Using AI and Satellites to Track Illegal Fishing in Marine Protected Areas

2025-08-01 15:00:11

Marine protected areas cover more than 8% of the world’s oceans today, but they can get a bad rap as being protected on paper only.

While the name invokes safe havens for fish, whales and other sea life, these areas can be hard to monitor. High-profile violations, such as recent fishing fleet incursions near the Galapagos Islands and ships that “go dark” by turning off their tracking devices, have fueled concerns about just how much poaching is going undetected.

But some protected areas are successfully keeping illegal fishing out.

In a new global study using satellite technology that can track large ships even if they turn off their tracking systems, my colleagues and I found that marine protected areas where industrial fishing is fully banned are largely succeeding at preventing poaching.

What Marine Protected Areas Aim to Save

Picture a sea turtle gliding by as striped butterfly fish weave through coral branches. Or the deep blue of the open ocean, where tuna flash like silver and seabirds wheel overhead.

These habitats, where fish and other marine life breed and feed, are the treasures that marine protected areas aim to protect.

These vessels can operate worldwide and stay at sea for years at a time with visits from refrigerated cargo ships that ferry their catch to port. China has an extensive global fleet of ships that operate as far away as the coast of South America and other regions.

The global industrial fishing fleet — nearly half a million vessels — hauls in about 100 million metric tons of seafood each year. That’s about a fivefold increase since 1950, though it has been close to flat for the past 30 years. Today, more than one-third of commercial fish species are overfished, exceeding what population growth can replenish.

When well-designed and enforced, marine protected areas can help restore fish populations and marine habitats. My previous work shows they can even benefit nearby fisheries because the fish spill over into surrounding areas.

That’s why expanding marine protected areas is a cornerstone of international conservation policy. Nearly every country has pledged to protect 30% of the ocean by 2030.

Big Promises — and Big Doubts

But what “protection” means can vary.

Some marine protected areas ban industrial fishing. These are the gold standard for conservation, and research shows they can be effective ways to increase the amount of sea life and diversity of species.

However, most marine protected areas don’t meet that standard. While governments report that more than 8% of the global ocean is protected, only about 3% is actually covered by industrial fishing bans. Many “protected” areas even allow bottom trawling, one of the most destructive fishing practices, although regulations are slowly changing.

The plentiful fish in better-protected areas can also attract poachers. In one high-profile case, a Chinese vessel was caught inside the Galápagos Marine Reserve with 300 tons of marine life, including 6,000 dead sharks, in 2017. This crew faced heavy fines and prison time. But how many others go unseen?

Shining a Light on the ‘Dark Fleet’

Much of what the world knows about global industrial fishing comes from the automatic identification system, or AIS, which many ships are required to use. This system broadcasts their location every few seconds, primarily to reduce the risk of collisions at sea. Using artificial intelligence, researchers can analyze movement patterns in these messages to estimate when and where fishing is happening.

But AIS has blind spots. Captains can turn it off, tamper with data or avoid using it entirely. Coverage is also spotty in busy areas, such as Southeast Asia.

New satellite technologies are helping to see into those blind spots. Synthetic aperture radar can detect vessels even when they’re not transmitting AIS. It works by sending radar pulses to the ocean surface and measuring what bounces back. Paired with artificial intelligence, it reveals previously invisible activity.

A radar image shows ships in a line and also inside the marine park.

Synthetic aperture radar still has limits — primarily difficulty detecting small boats and less frequent coverage than AIS — but it’s still a leap forward. In one study of coastal areas using both technologies, we found in about 75% of instances fishing vessels detected by synthetic aperture radar were not being tracked by AIS.

New Global Analysis Shows What Really Happens

Two studies published in the journal Science on July 24, 2025, use these satellite datasets to track industrial fishing activity in marine protected areas.

Our study looked just at those marine protected areas where all industrial fishing is explicitly banned by law.

We combined AIS vessel tracking, synthetic aperture radar satellite imagery, official marine protected area rules, and implementation dates showing exactly when those bans took effect. The analysis covers nearly 1,400 marine protected areas spanning about 3 million square miles (7.9 million square kilometers) where industrial fishing is explicitly prohibited.

Two images show lots of fishing activity around the edges of the protected area, but little activity inside it.

The results were striking:
  • Most of these protected areas showed little to no signs of industrial fishing.
  • We detected about five fishing vessels per 100,000 square kilometers (38,610 square miles) on average in these areas, compared to 42 on average in unprotected coastal areas.
  • 96% had less than one day per year of alleged illegal fishing effort.

The second study uses the same AIS and synthetic aperture radar data to examine a broader set of marine protected areas — including many that explicitly allow fishing. They document substantial fishing activity in these areas, with about eight times more detections than in the protected areas that ban industrial fishing.

Combined, these two studies lead to a clear conclusion: Marine protected areas with weak regulations see substantial industrial fishing, but where bans are in place, they’re largely respected.

A map of global industrial fishing activity shows few vessels per 100,000 square kilometers in most fully protected and highly protected areas. The average is about nine times lower than what’s found in unprotected coastal areas. Jennifer Raynor, Sara Orofino and Gavin McDonald

We can’t tell whether these fishing bans are effective because they’re well enforced or simply because they were placed where little fishing happened anyway. Still, when violations do occur, this system offers a way for enforcement agencies to detect them.

Reason for Optimism

These technological advances in vessel tracking have the potential to reshape marine law enforcement by significantly reducing the costs of monitoring.

Agencies such as national navies and coast guards no longer need to rely solely on costly physical patrols over huge areas. With tools such as the Global Fishing Watch map, which makes vessel tracking data freely available to the public, they can monitor activity remotely and focus patrol efforts where they’re needed most.

That can also have a deterrent effect. In Costa Rica’s Cocos Island National Park, evidence of illegal fishing activity decreased substantially after the rollout of satellite and radar-based vessel tracking. Similar efforts are strengthening enforcement in the Galapagos Islands and Mexico’s Revillagigedo National Park.

Beyond marine protected areas, these technologies also have the potential to support tracking a broad range of human activities, such as oil slicks and deep-sea mining, making companies more accountable in how they use the ocean.

Senior Project Coordinator – Media in Exile

2025-07-31 16:49:32

The Thomson Reuters Foundation is seeking a highly organised and motivated Senior Project Coordinator to manage the delivery of grants and capacity building interventions for media in exile. This is an exciting time to join the Foundation, as the postholder will play an essential role in delivering an element of TRF’s expanding programme of support to independent exiled media organisations, which has grown substantially since 2022.

Exiled/hybrid media is an increasingly important feature of the global independent media landscape: as the spread of authoritarianism, restrictions on press freedoms and violence against journalists forces media organisations to leave their home countries to continue providing citizens with fair and accurate coverage of critical events. This phenomenon poses complex business, technological and journalistic challenges and TRF is committed to playing a leading role in supporting independent journalism to respond and thrive.

The programme of work includes a significant training programme element and a grant-making component, with a mix of long-term grants; shorter-term project funds; and associated technical assistance available to eligible organisations. This role would sit within the core project team and focus on the design and delivery of key programmatic elements, including a capacity building training programme and a one-year grant programme which fits within the wider programme for exiled media. The successful post holder will coordinate and lead the implementation of these, working closely with the Project Manager and Finance Team to ensure grants and training delivery are managed to a high standard and contribute to TRFs overall strategic and learning objectives for the programme.

Notes from a Small Island: Bernadette Carreon on Covering Palau, the Pacific, and the World 

2025-07-31 15:00:23

10 Questions Palau Bernadette Carreon

When, as a young journalist, Bernadette H. Carreon took a reporting job at a newspaper in the small Pacific island nation of Palau; she didn’t know it would become her home — and reporting beat — for the next 20 years.

Born and raised in Manila, Carreon studied journalism at the University of Santo Tomas, and worked in the capital before making the move from the Philippines — with a population of 118 million — to Palau, with a population of 21,000 — to work for the now-defunct Palau Horizon.

“I wanted to do something different, and I wanted to travel,” Carreon told GIJN. “Palau was the first place that had a vacancy for a reporter. I was young. I wanted to try it for a year, and the rest is history.”

For more than two decades, Carreon was based on a small island but covered a vast beat — the Pacific — for local outlets and international newspapers and agencies, including the Guardian, Agence France-Presse, and the Australian Broadcasting Corporation, covering topics as diverse as Palau’s cryptocurrency plans and the global seafood industry.

As the OCCRP’s Pacific investigative reporter, she worked on the 2022 story Pacific Gambit: ​​Inside the Chinese Communist Party and Triad Push into Palau, which exposed how her adopted home had become a front in the rivalry between China and the West. The OCCRP reported that “string of questionable ventures” in Palau, such as illegal online gambling operations connected to organized crime figures, were not a matter of “isolated criminal outfits,” but Beijing’s latest step in an attempted push into the Palau — a strategic Western ally in the Pacific and one of only 14 nations that diplomatically recognize Taiwan.

OCCRP Pacific Gambit, Bernadette Carreon

She is also the project manager for the Pacific Freedom Forum, a press freedom watchdog raising funds for Pacific-based journalists to help them fight legal action and intensifying attacks against their work.

GIJN spoke with Carreon, who is now based in the United Kingdom, about her favorite investigation, her “old-school” journalism heroes, and how to navigate reporting where everyone knows your name.

GIJN: Of all the investigations you’ve worked on, which has been your favorite and why? 

Bernadette Carreon: The Pacific region and Pacific journalists are still new to investigative journalism. But one of my favorites is Pacific Gambit: ​​Inside the Chinese Communist Party and Triad Push into Palau. The story has legs to it. Although the investigation was published in 2022, it has been referenced a lot by international publications on organized crime. It also made Palau known for political stories. International reporters who come to Palau now always include stories on geopolitics and the Chinese Communist Party (CPP)’s alleged influence in the region. It opened up the subject of alleged CCP influence in the Pacific.

GIJN: What are the biggest challenges in terms of investigative reporting in your country/region?

BC: I’ve spent my time in the Pacific, in Palau, specifically, for over 20 years. Palau is small, really small. Small can be good, and small can be bad. It has its benefits and its hindrances. It can be hard to do investigative reporting because everyone knows you, and everyone knows where you live. And when I was starting, technology and the internet weren’t as good as they are today. Also, because everyone knows me there, it can be hard to do investigative journalism because everyone knows who reported it.

And also, when I arrived in Palau, I was an overseas worker, a foreign worker. Palau also didn’t really respect journalists at the time, and it was hard, especially because I was not from there. It was hard for me to report because there was a lack of respect, and I was a foreigner. My status in Palau at that time was based on my immigration papers. So I could be sent home.

GIJN: What’s been the greatest hurdle/challenge that you’ve faced in your time as an investigative journalist? 

BC: Of course, censorship. In Palau, they have this respect for the elders. They have this respect for politicians, for people in authority. It’s the culture that you don’t shame your elders, and you don’t shame someone who’s in authority. To me, the biggest challenge is self-censorship. Because I’m part of the community. Sometimes I think, who would I hurt? Would I shame people around me? I see them in personal events, like school events with my child, or parties, or the supermarket, because Palau is so small. And people don’t tend to talk. It can be difficult to find sources and information. Getting documents is also hard, they won’t easily give them to you because they’re a higher authority from whom you have to ask permission.

Funding is a challenge. Investigative journalism takes time and resources. And usually it’s a one-woman show or one-man show, or a small newsroom. So you’re the editor, you’re the photographer, you’re the reporter, you’re the driver. That’s just so taxing emotionally and financially.

GIJN: What is your best tip for interviewing? 

BC: Those who have worked with me would probably say that I have a good communication style, that I am direct and firm, but respectful. You have to listen to what people are saying. Because I’m from the Philippines, we have a saying — I’m going to try to translate it — ‘if you talk to everyone, no information is a waste.’ Have a conversation with people you are interviewing; don’t just ask questions that feel like interrogation.

I also do like to research the people I interview: What kind of questions will make them angry, or are they someone who will be evasive? So I have to think of a way to ask that question, so I research the person I’m interviewing. I try to use the right words, the right tone to interview, a tone that’s not aggressive, a tone that’s very warm, but at the same time, direct.

GIJN: What is a favorite reporting tool, database, or app that you use in your investigations?

BC: I’m old school; the way I do reporting is building sources. I like to talk to people. So, messaging apps. In the Pacific, people still like to use Facebook Messenger, so I talk a lot to my sources through Facebook, because if you see them or meet them in a coffee shop, because it’s a small country people will say, ‘Why is she talking to the reporter?’

And when I was working with the OCCRP, I relied a lot on their Aleph tool —  a great database on public information with a large dataset. I did use that, especially in the Pacific Gambit story.

GIJN: What’s the best advice you’ve gotten thus far in your career, and what words of advice would you give an aspiring investigative journalist? 

BC: I’m not sure it was advice to me, but I heard it at the last Global Investigative Journalism Conference (GIJC2023) in Sweden. One of the panelists said that investigative journalism is really hard, so it’s a team sport. You can’t do it alone — it involves collaboration with other journalists, editors, and researchers.

From my editors, the best advice I got is not to take everything personally. To aspiring investigative journalists, I would say be patient. Be patient, because if you are impatient, you kill a story.

GIJN: Who is a journalist you admire, and why?

BC: Because I’m old school, probably the biggest ones are Bob Woodward and Carl Bernstein, who broke the Watergate scandal, because we studied that in the journalism school in the Philippines. And of course, I’m from the Philippines, so I admire Maria Ressa. She opened up the Philippines to investigative journalism. I like Christiane Amanpour, who gets interviews that nobody else does. And from The New York Times, I admire Megan Twohey — she does a lot of stories that impact women and also exposes systemic failures.

GIJN: What is the greatest mistake you’ve made and what lessons did you learn?

BC: I have made a lot of mistakes. The first mistake I made was when I was working in Manila as a young reporter. There are a lot of journalists in Manila, and it’s very competitive. I always went with a pack of young reporters, and we would kind of do stories together. There was a story where we thought we had an exclusive — but it turned out the story was not true, and it was published… I don’t know how I kept my job, probably because I was young at that time, some of the more senior reporters protected me and defended me. Don’t believe what one source says, even if they’re a person in authority — it doesn’t mean that they are going to tell you the truth. Always fact-check.

I made a lot of mistakes. There were stories where I was scared to ask questions, or I didn’t want to do it because it was scary. Then one of my editors said, ‘Well, if you don’t want to do the story, then don’t come back to the office.’ Those are the mistakes I do —  to show fear.

GIJN: How do you avoid burnout in your line of work?

BC: Take a break and do something other than being a reporter, like hobbies. It’s nice to have a group of other journalists who understand you, so you can talk to them about what you’re feeling, because it can take an emotional toll on you. As Buddhist philosophy says, empty yourself. If you’re going to another investigation, just get rid of the stuff that you’ve already done and move forward.

GIJN: What about investigative journalism do you find frustrating, or do you hope will change in the future? 

BC: Coming from a small region and having moved to the UK, I find it hard to get into investigative journalism because my experience is from one region. That’s the thing about being in a small region — you don’t become an expert on only one issue. Because you have to cover everything from sports to geopolitics, from politics to the environment.

Also, that there won’t necessarily be an immediate result [when pursuing a story], because there are a lot of dead ends in a story. And that your story and pitch depend on your editor or the publication you’re writing for — they can make decisions for you that this story is not worth pursuing, even when you know in your gut that it is. And of course, lack of funding, especially in this environment at the moment.

GIJN Reporting Guide for Landfill Methane Emissions and Solutions

2025-07-30 15:00:34

GIJN reporting guide for landfill methane emissions

Methane gas spewing from landfills and waste dumps contributes significantly to global warming, but “garbage” often flies under the media’s radar.

Reducing methane emissions is one of the fastest and most cost-effective ways to slow climate change. Methane from the waste sector is the third-largest human source of methane after the agriculture and fossil fuel sectors.

Investigating methane emissions from waste sites and reporting on the practical solutions can be done worldwide. Plus, improving how waste is handled benefits the health of those living near disposal sites.

How waste is managed is not only a major climate change story, but also an important local story.

Learning about methane emissions is now easier because of the availability of satellite and remote sensing data. However, ground-level reporting is essential.

Solutions exist. There are practical and economical ways to reduce methane emissions from solid waste. Investigative reporting can explore whether viable solutions are being pursued, and if not, why.

This GIJN guide will describe what resources are available and what questions to ask about methane emissions from landfills and how to reduce them.

The main topics covered are:

Examples of great investigations on the issue can be found at the end of this guide.

Section One: The Big Picture

Methane emissions are a major contributor to global warming.

The decomposition of organic matter in an oxygen-free environment results in the creation of methane gas as one by-product.

Methane (CH₄) is the second-largest contributor to climate warming after carbon dioxide (CO₂), which is more abundant and longer-lasting. Methane, over a 20-year time frame, is 80 times more potent than carbon dioxide as a greenhouse gas. “A molecule of methane traps more heat than a molecule of carbon dioxide, but methane has a relatively short lifespan of seven to 12 years in the atmosphere, while CO₂ can persist for hundreds of years or more,” according scientific research. (See a summary by the US National Aeronautics and Space Administration (NASA).)

Decomposition happens in nature all the time, resulting in methane emissions. Rising temperatures are accelerating methane emissions — for example, in the Arctic tundra. But human activities are the real culprits, generating an estimated 60% of all methane emissions. (See NASA and other sources listed at the end of this section.)

Organic waste, such as food and paper, accounts for about 20% of anthropogenic (human-caused) methane emissions worldwide, according to the 2021 United Nations Global Methane Assessment: 2030 Baseline Report. Agriculture accounts for 40% of methane emissions (32% from livestock, 8% from rice production), and fossil fuels contribute another 35%, the same report said.

Waste Production Increasing

The amount of waste is projected to increase.

“By 2050, in a business-as-usual scenario, the world is projected to generate 73% more MSW (municipal solid waste) than in 2020,” the World Bank said in a 2023 report.

“Every year across the globe more than two billion tons of municipal solid waste (MSW) is generated,” according to a 2024 report by the UN Environment Programme (UNEP). “If packed into standard shipping containers and placed end-to-end, this waste would wrap around the Earth’s equator 25 times, or further than traveling to the moon and back.” (And that doesn’t count construction and demolition waste, industrial waste, agricultural waste, and health care waste.)

“High-income countries produce the most waste per capita, where rising incomes and consumption have been associated with higher waste generation,” the World Bank noted. But that could be changing. The report elaborated: “Going forward, waste generation rates in most high-income countries are expected to either remain stable or slightly increase. Middle-income countries, conversely, are projected to see the largest increase in both per capita waste generation and total waste generation.”

The generation of more waste “will be driven by high levels of growth in both economic activity and population” and urbanization, according to the World Bank. “Waste volumes are projected to grow by more than 2.5 times for low-income countries (LICs) and nearly double for middle-income countries.”

Want another metaphor?

The world population generated 1.9 gigatons per year of municipal solid waste (MSW) in 2015 and is expected to generate about 3.5 gigatons per year of MSW in 2050, according to one study. That’s a lot. A gigaton is 1,000,000,000 metric tons. (A metric ton equals 2,205 pounds, about 10 percent heavier than a US ton.)

The authors of the study said that projected waste in 2050 would equal the weight of 200 million elephants; enough elephants to stretch from the Earth to the moon.

Landfills Everywhere

Where does all that waste go?

There are 48,000 landfills worldwide, according to a 2022 estimate by the UK publication Landfill Today.

There’s a distinction between “landfills,” where methods are being employed to mitigate environmental damage (such as liners to prevent water seepage), and “waste sites,” where there are no controls and garbage is simply dumped, and often burned.

The 2024 UNEP report said 38% of the MSW generated globally in 2020 was “uncontrolled.” Over 90% of waste in low-income countries is still openly dumped or burned, according to a 2018 World Bank report. One study of India identified 3,184 existing dump sites, handling about 160,038.9 tons per day of solid waste, with only half of it treated.

While “open” burning and random dumping of waste is widely seen as environmentally damaging, incineration to produce energy (waste-to-energy) is controversial. Burning causes carbon dioxide emissions, along with “black carbon” and other pollutants. This guide, however, focuses on landfills.

Managing all waste properly, in landfills, is costly. “Municipalities in low-income countries are spending about 20% of their budgets on waste management, on average,” according to a World Bank report.

Other Pollutants, Too

While this guide is focused on methane emissions, there are many other types of toxic pollution from landfills that have negative health consequences.

Some of the other pollutants from landfills are airborne, while others leach into the soil and groundwater. These pollutants, and their effects, include:

  • Benzene, which causes cancer, found mainly in plastics;
  • Volatile organic compounds (VOCs) that react in the sunlight with nitrogen oxides to form ozone pollution, which can cause respiratory health problems;
  • Hydrogen sulfide, which smells like rotten eggs and can cause irritation to the eyes and respiratory system, and derives mainly from gypsum wallboard;
  • Toluene, which damages the nervous system, and is used in many applications as a solvent;
  • Per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals.” According to new research, landfill gas serves as a major pathway for the release of PFAS.

And methane, besides being a potent greenhouse gas, contributes to ground-level ozone that is linked to respiratory diseases and premature deaths.

Dumping garbage outside of landfills can damage the environment, often with significant human and economic consequences. For example, wetlands can be destroyed, natural fisheries can be degraded, and beaches polluted.

In addition, poor and Indigenous populations are more likely to be negatively affected by waste disposal and pollution, since these sites are often located in their vicinity. Not to mention the impact on waste-site workers, including those in the “informal sector” who scavenge sites. In the US, the modern environmental justice movement can be traced, in part, back to “Dumping in Dixie,” a 1990 book showing that landfills were disproportionately sited next to poor and Black communities.

Noxious smells and increased illness in neighboring communities may well be important subjects for stories. Gypsum drywall has been associated with the generation of hydrogen sulfide. Odors may also signal leaky gas collection systems. “If you smell something, that is oftentimes indicative of a problem,” said Tom Frankiewicz, who leads Waste Sector Methane Mitigation at the Rocky Mountain Institute (RMI), an independent, non-partisan, nonprofit organization.

In sum, many waste management problems, and solutions, are related to methane emissions.

Solutions Are Available

While the problems seem overwhelming, journalists should be aware that a wide variety of cost-effective solutions can yield significant benefits, according to policy experts.

Methane emissions from waste are largely preventable and need to be reduced by at least 30 to 35% to limit global warming to 1.5°C., according to the UN’s 2021 Global Methane Assessment.

“Transforming open dumpsites worldwide into sanitary landfills, while diverting organic waste to composters and bio-digesters, can decrease methane emissions by 80% (60–89%)… “ according to a study published July 2025, in Nature Climate Change.

The solutions are good investments. As much as 60% of waste-sector targeted measures are low cost or pay for themselves quickly by saving money (negative cost), according to the report.

The waste sector has proven to have the greatest mitigation potential for sources of pollution after the oil and gas sector, even though it only contributes 20% of overall emissions.

More on solutions to come later, but first a look at measurement.

Section Two: Identifying Methane Emissions

Methane is invisible to the naked eye, but emissions can be made visible and documented using a variety of techniques, both on the ground and from above.

“We can’t really manage it if we don’t measure it,” said David Risk, a Canadian methane researcher, while telling the CBC about a simulation project run by FluxLab, an organization he heads.

Satellites, airplanes, and drones are increasingly a great source for images and emissions data.

The levels of emissions seen from above frequently exceed what’s officially reported. Ground measurements of methane emissions, from oil fields and landfills, are regularly underestimated. A 2024 study by Carbon Mapper in the US found “a large discrepancy and generally poor correlation” between what scientists observed from the air and what was reported to the US government. This underestimation was supported by an earlier NASA study.

Ground measurement can be gathered by landfill operators, but the results can be hard to get. Governments could mandate measurement, or do it themselves, but often do not. Instead, the focus is more on finding major leaks than identifying emission rates. Even when operators are mandated to report emissions, the data may not be made public.

“[W]hile tools to collect data exist, their application and translation into actions are lacking, meaning there is a huge untapped potential of unlocking action and finance through data collection and data use,” according to a March 2025 report by the Climate and Clean Air Coalition (CCAC), a multilateral group whose Secretariat and Trust Fund is hosted by UNEP.

More transparency is needed about potential solutions, according to the CCAC. “Key data gaps include the volume and composition of waste (particularly food loss and waste), and the quantified benefits of relevant prevention, recovery, and recycling solutions on human and ecosystem health, job creation, and economies,” according to CCAC. The report includes forms to be used for data collection.

The CCAC LOW-Methane Data Strategy has supported some national projects, “designed to unlock action on methane mitigation from organic waste by improving data collection, analysis, and application.”

Methane Tracker from the International Energy Agency provides estimates of annual national methane emissions from the waste sector.

What Are the Units of Emission Measurements?

Greenhouse Gas Equivalencies Calculator

Methane emissions are usually expressed as the volume emitted per hour: kilograms per hour (kg/hr) or tons per hour.

To make these figures more relatable, the Guardian wrote: “An outburst near Lahore in Pakistan in February leaked at 214 tons an hour, equivalent to 34 million car exhausts.”

There’s a tool to make this conversion: the Greenhouse Gas Equivalencies Calculator, run by the US EPA.

From Above: Satellite Images Proliferating

Orbiting satellites are providing valuable data on greenhouse gas emissions, including methane from landfills.

GIJN did some test drives and learned that the data can be very useful, but with some caveats. The main one being that supplementary ground-level reporting is essential.

Satellite data usually includes longitude and latitude coordinates for specific emissions but may not pinpoint a landfill and usually does not identify the emission source by name. This means it’s essential to use your local knowledge of landfill locations to figure out where the emissions are coming from and who’s responsible.

Here are a few other things to keep in mind about satellite images:

  • Satellite observation has its complications. The circling cameras take snapshots, but there are important variables, including how often the satellite flies over the site and the resolution of the images. Winds blow emissions, which is why the plumes shown are often elongated. Interview the sources of the information about the data and its limitations.
  • Note that the providers usually include an “uncertainty factor.”
  • The data provided by these sources typically is at least 30 days old, usually due to contractual obligations of providers who sell the data commercially.

For a detailed explanation of satellite detection of methane, read a April 2025 report by The Center for Law, Energy & the Environment (CLEE) at the University of California, Berkeley, and The Emmett Institute at the University of California, Los Angeles.

After looking at the data online, ask for assistance from the data providers. They may help you navigate the maps and the data. On request, some will provide more specific and more periodic observations. Many of these sources will work with reporters.

Satellite Image Sources

These sources are listed roughly in order of how much information is available.

Carbon Mapper: This US nonprofit posts global carbon dioxide and methane emissions from the fossil fuel, waste, and agriculture sectors on a searchable map. To refine the view to methane plumes from waste specifically, find the tiny print “Show Filters” just below the search bar. Locate “Sector” and pick “Solid Waste.” Also select “CH4.” This will pull up plumes of methane — indicated on the map as purple circles — that have been observed by airborne and satellite instruments. At the geographic location you want, click the circle to pull up a specific plume and get key details about the observed emissions event, such as the emissions rate and the number of observations. Previous observations, if available, are shown in a box in the right corner. There’s also a Product Guide. You can create saved searches and receive email alerts for newly published data on the Carbon Mapper portal. Press contacts are Kelly Vaughn ([email protected]), Annabelle Blair ([email protected]) or [email protected]

Methane Alert and Response System (MARS): This international methane tracking effort is run by the UN Environment Programme, relying on many public and private sources. The map view can be narrowed to “waste” and by date. Clicking on the identified spots will bring up emissions information. While in map view, click the vertical words “Access Data” to see various download formats. UNEP has an access to information policy that may be used to make requests for additional information. However, UNEP will not provide the notices it sends to governments about significant emissions. Reporters could try using national access laws to request the notices. Contact [email protected].

The CAMS Methane Hotspot Explorer: New in 2025, this resource shows large methane plumes from strongly emitting localized sources using European Space Agency Copernicus Sentinel-5P TROPOMI methane satellite data. The data are updated daily and provide global coverage. Select source type, “Urban/landfill” and set the time period on map. The map shows only the last 14 days, but all data can be downloaded. Hover over identified spots to see more information. The exact sources usually are not identified, but the most likely source type is. See documentation. Contact the Copernicus press team.

GHGSat Spectra: A periodically updated map posted by the Canadian-based company, GHGSAT, includes a selection of recent major emissions worldwide, usually about seven months old. (Sign-up is required for access.) Clicking on any of the locations shows a table of the featured emissions and identifies some as “waste management.” Also provided: the time the image was taken and rate of flow. The precise location is not given, but there’s a close-up image of the plume. Above the map it says: “Upgrade your account to add real-time emission, catalog data and analytics!” A spokeswoman said that, upon request the company will “share aggregate statistics about the prevalence of emissions at a regional level to give a sense of scale” and also provide specific local data to journalists. Contact Alison Boyer ([email protected]) or [email protected].

Kayrros Methane Watch: The French company Kayrros offers some of its data for free. The Kayrros map, after you click “Access Data,” allows you to narrow a search. See “Source Type” and click on “Other Human Activity” (the category in which landfill emissions would fit). You also can define the timeline. The map may show multiple readings from a location, as overlapping orange circles, but these are not easy to click on. Instead, go to “Download Data” at the lower right and use the tool with the connecting dots to define the area of interest. Then download the data. Media contact: [email protected]

Climate Trace: The not-for-profit coalition has a map that can be narrowed to cover the waste sector (and five sub-sectors). There were 363 sites identified in a May 2025 check. Methane emissions data (in a CO₂ equivalent) is shown, but you can also switch to methane by using the drop-down menu at the top right of the screen. Updated monthly. Media contact: [email protected]

WasteMAP: This US nonprofit identifies specific landfills on a map and estimates how much methane they are emitting. These estimates are based on public data from a variety of sources, modeling, and sometimes satellite images. WasteMAP researchers also calculate total country and city emissions. The data here is mostly from 2022, but projections are made for identified locations. The project was created by the Rocky Mountain Institute and the Clean Air Task Force.

On the Ground: Landfill Operators Collect Data

Satellite data can be a great starting point for an investigation, but it isn’t essential and needs to be supplemented with other information to fill out the picture.

Interview landfill operators and relevant government officials. They may be skeptical about the satellite data and say the problems have been fixed, but there’s lots to ask about what they know about methane emissions.

Starting questions for landfill operators:

  • What data exists on your methane emissions?
  • What methods do you use to monitor emissions?

Be prepared for complex answers and be skeptical.

“[M]any of these large persistent landfill emissions are not included — or are misrepresented — in traditional emissions accounting methods,” said Tia R. Scarpelli, staff scientist at Carbon Mapper in 2024 testimony to a US Senate committee.

Importantly: ask for documentation.

In some countries, landfill operators are required to file reports with regulators. If so, the documents may or may not be covered by freedom of information laws.

Seek out local environmental groups, scientists, and other experts.

A lack of data from a landfill operator is itself a story. No measurements? Why not?

Now let’s look at the ways emissions are measured on the ground.

Ground-Level Measurement Techniques

The quality of data gathered on site depends on which measurement techniques are used and how well, among other factors.

Ask landfill operators about their practices.

Measurement techniques include walking surveys with handheld methane detectors that use laser technology to map emissions.

“There is no single monitoring technology that can ‘see’ all of the methane at the granularity that’s needed at landfills,” Scarpelli wrote in a 2024 article about research on US landfills. Getting too close to the “working face,” where trucks drop off their loads, may be dangerous, Scarpelli wrote, “… which means that large emission sources may be missed during the survey.”

Her research showed that much of the methane released, at least at US landfills, comes from the working face, where solid wastes are discharged, spread, and compacted before being eventually covered up. Operators also commonly identified construction activity on the landfill surface, malfunctioning gas wells, taking gas capture wells offline, and cracks in surface cover as sources of emissions, she found.

Robotic dogs equipped with methane sensors are now patrolling landfill sites, and drones are being used to measure emissions, too, RMI reported: “Compared to traditional monitoring, where a technician walks the site for miles, these methods are safer, more efficient, and more economical.”

See a summary of techniques on page eight of the CCAC report. Also note a Waste Wise Cities guide from UN-Habitat with seven steps for collecting data on municipal solid waste.

Methods matter. But even if some methods have faults, the data over time may identify trends.

Monitoring also applies to “flaring,” or burning off of landfill gases. Flaring does reduce methane emissions, but is not ideal compared to other solutions. Flares not operating correctly increase methane release, so monitoring is necessary. “Enclosed” flaring is an alternative that produces minimal emissions, although it does create some particulate air pollution. The World Bank’s Global Gas Flaring Tracker has data and reports on flaring, but not on specific landfill sites.

World Bank global gas flaring data tracker

Can reporters use handheld methane monitoring devices? Not really.

First, without access to the landfill, accurate measurements can’t be taken.

Second, infrared cameras and other specialized equipment used from a distance can show the existence of methane emissions from point sources, such as flare stacks and vents, but not more dispersed emissions. These devices are expensive and require training, so it’s probably best to work with environmental groups, some of which are happy to help journalists in joint projects. (For more, see the investigating leaks and emissions chapter of GIJN’s Methane Guide.)

Nevertheless, images from infrared cameras do provide excellent graphics. Satellite images can serve the same visual purpose.

Finally, what goes into a landfill will affect what comes out. Estimating emissions by measuring inputs is also feasible, although complicated.

The Solid Waste Emissions Estimation Tool (SWEET) is an Excel-based tool that quantifies emissions of methane, black carbon, and other pollutants from sources in the municipal solid waste sector. The tool was created by the Global Methane Initiative, an international public-private project. While it’s designed for experts, landfill officials can use it as well — for example, in detailed studies, such as this one from 2022 on Accra, Ghana. Journalists can ask landfill officials if they use it or similar tools to track output from their sites

Section Three: Solutions

GIJN reporting guide landfill methane emissions section 3

A variety of actions could significantly reduce greenhouse gas emissions from landfills. Delving into possible solutions during reporting may be the real value of a landfill investigation.

Potential solutions include:

  • Reducing the amount of organic material disposed of in landfills.
  • Capturing emissions for a renewable source of energy, sometimes called bio-gas.
  • Cutting emissions with improved landfill operations.
  • Setting emissions limits through law.

More below on each of these, but also check out a thorough survey option of solutions and implementation steps by the Clean Air Task Force (CATF), The Waste Methane Toolbox: Policy Solutions for a Low Methane Future, which notes that waste and wastewater are responsible for approximately 20% of global anthropogenic methane emissions. That’s equivalent to roughly 5.4 gigatons of carbon dioxide equivalents annually, says CATF. Country examples are provided for Colombia, Germany, India, Italy, Perú, the Republic of Korea, and the US.

CATF wrote, “When we consider examples of countries that have successfully used these approaches to improve waste management and reduce climate impacts… it becomes clear that there is no silver bullet or single solution to achieve this goal.”

But the benefits can be substantial.

Reductions of about 80% below baseline methane emissions by 2050 could be obtained if reform steps are taken, according to a 2020 study by scientists published in Environmental Research Communications.

“Fortunately, there are a number of technically feasible, readily available strategies to reduce landfill emissions today, at modest cost,” said the RMI’s waste expert Frankiewicz in his 2024 testimony before a US Senate committee.

“Modernizing landfill operations — through comprehensive leak detection and repair, expanded gas collection system coverage, and enhanced cover practices — can cut methane immediately from waste-in-place, while protecting nearby communities from co-pollutants,” according to Frankiewicz.

He also said that “scaling up efforts that keep organic waste out of landfills — through strategies like edible food donation and composting — will avoid future landfill methane generation and ensure organic materials are put to their highest and best use in the circular economy.”

“The economics of it check out,” said another expert, who works internationally but preferred not to be quoted because of his institutional connection.

There is increasing private sector interest because some of the solutions can be economically viable. “Bankability is becoming the big story,” according to the same expert. But investment is slow to come, and what there is, is mostly for extraction of bio-gas. More on that below.

Some financial assistance for landfill improvements has been provided by international development agencies, such as the World Bank. Some mitigation projects have been funded by the CCAC, a UNEP initiative, including in Panama, Senegal, Nigeria, Uganda, Argentina, Cambodia, Paraguay, Brazil, Pakistan, Costa Rica, and Liberia. (The list includes those started in 2024.)

However, the prospects for implementing solutions vary widely.

One study published in the journal Waste in 2025, began: “In sub-Saharan Africa municipal solid waste management faces significant challenges, including inadequate infrastructure, increasing waste generation, and limited resources, leading to severe environmental and public health issues.” The article said that governance structures, data availability, and informal practices prevalent in sub-Saharan Africa make it “difficult” to introduce appropriate innovations in waste management customized to local needs.

In terms of climate change ambitions, in many developing countries there’s a significant disconnect between national climate change goals for the waste sector and what is achieved, according to the 2021 World Bank report Bridging the Gap in Solid Waste Management.

“Central authorities often regard solid waste management as a local function and beyond their mandate,” the report says. “Line ministries often do not see it as being either their role or practical for them to provide the guidance, support and resources needed by local authorities to implement national policy. Yet, the primary responsibility for setting the overall institutional, policy and legislative framework for the municipal waste management sector belongs with central governments.”

A taste of how large the challenges are is provided in a 2025 study of three rural Cambodian cities. All waste was going to “unsanitary open dumpsites without soil coverage, landfill liners, leachate treatment facilities, or gas control systems.” Plus, “open burning of waste was observed across all the landfills and temporary dump sites,” according to the researchers.

For investigative reporters, this means that there will be many different situations and possible solutions.

Mitigation efforts may already be underway, so the questions to ask may be about whether they are working.

“Most” landfill operators, said Frankiewicz, who consults internationally, “are trying to do the right thing, but it’s challenging.”

What to Ask, Who to Ask

Approaching landfill operators and government officials might best be done initially with open-ended questions about the problem and what solutions are being employed or being considered.

National governments have an interest in this. In pursuit of global climate change goals, most governments make pledges to reduce greenhouse gas emissions.

Senegal, for example, aims to reduce its overall methane emissions 7% by 2030, or by 29% over the same period if external assistance is provided. “For the waste sector, Senegal’s emissions reduction intentions are set at 11% until 2030 and up to 65% if adequate external funding can be provided,” summarized a UN report.

Getting to these goals will involve various strategies.

Financially strapped countries lacking basic infrastructure may need quite different approaches, as described in A Playbook for Municipal Solid Waste Methane Mitigation by the Rocky Mountain Institute.

The playbook identifies four municipal solid waste management types. The lowest category is “characterized by low to medium collection rates, poor waste management systems, low recycling rates, and limited or no waste treatment prior to final disposal.”

The playbook — which is a good primer for reporters — describes strategies to mitigate methane for each of the four archetypes, “providing a starting point for countries to further customize methane abatement solutions unique to their local context.”

For countries in the lowest category, lack of access to finance for capital projects is “a major obstacle.” As a result, “these countries can start reducing methane emissions by building basic infrastructure or implementing relatively low-cost operational improvements at the dumpsites.” These strategies “can include developing small-scale decentralized organics processing facilities, limiting waste pickers’ access to dumpsites, installing landfill covers, and installing basic gas capture and control systems (GCCS).” Examples given include the Dominican Republic, Guatemala, Nepal, Nigeria, Tajikistan, and Uganda.

The playbook doesn’t list all countries by categories, although it gives a handful of examples.

Use the categories in exhibits four through nine as a basis for questions. Pathways can be read in conjunction with a 2022 RMI report on “key strategies.”

Similarly useful as a source of ideas for questions is CCAC’s LOW-Methane Data Strategy.

Potential Sources

There are many sources to consult, including:

  • Environmental groups, especially those concerned with climate change;
  • Other non-governmental organizations and civil society organizations, including those looking to cut government costs and to reduce food waste;
  • Scientists and social scientists;
  • Waste management trade associations;
  • Businesses looking to cut their waste costs or help others do so;
  • Businesses hoping to profit from recycling, composting, and gas capture;
  • Potential customers for products such a fertilizer;
  • Affected citizens, such as neighbors of landfills.

Searching for news about landfills in your area may prove useful.

Here’s more about four main strategies for reducing methane emissions from landfills, followed by a collection of resources.

Reducing Organic Material Levels

Diverting organic waste from landfills can reduce methane emissions and pay other dividends.

“A third of the global trash mountain ‘built’ every year is generated by about one-sixth of the population (high-income countries),” noted one group of researchers, adding, “However, only around 13% is recycled and 5.5% composted.”

Reducing food waste is considered key. “Because food waste is the largest component of the organic waste stream, food loss and waste prevention is the best option to reduce methane emissions from municipal solid waste,” according to RMI’s Playbook. Keeping biodegradable waste from being sent to landfill is also underscored in an analysis by the International Institute of Applied Systems Analysis.

The mantra of “reduce, reuse, and recycle” will keep organics out of landfills. Among other things, food waste can be composted and paper can be recycled.

Plastics in the waste stream “is a major challenge to the diversion, recovery, and treatment of organic waste,” according to CATF’s The Waste Methane Toolbox. The amount of plastics can be reduced with a variety of prohibitions and incentives, the report says. Doing so reduces the cost of later separation.

Reducing organic waste disposal requires not only political will but also behavioral changes by the public and increased capital investment. For example, a 2022 report on Ghana underwritten by the World Health Organization noted that increased composting and recycling “would likely be preferred by society, but needs significant investments in capital, skilled labor, planning capacity and societal participation in waste separation.”

Figuring out the social, financial and political details can be complex.

Table Formal vs. informal recycling waste pickers in various cities

Image: Screenshot, World Bank, Bridging the Gap in Solid Waste Management report

Among other things, in many places, waste pickers are a key part of the equation — totaling an estimated 15-20 million individuals worldwide, who focus primarily on plastic recycling. “In Colombia, waste pickers have transformed their social and professional status, evolving from being seen as ‘disposable people’ to being recognized as providers of public recycling services,” according to a 2024 article by the Platform Cooperativism Consortium. Women in Informal Employment: Globalizing and Organizing (WEIGO) points out:It is well established that waste pickers contribute to reducing greenhouse gas emissions in many cities and are the backbone of recycling.”

National efforts are being tried in some countries.

The Swachh Bharat (Clean India) Mission, started in 2014, includes segregation of waste among its goals, and envisions diverting 80% of municipal solid waste from landfills by 2026.

There has been progress, but the Swachh Survekshan (National Sanitation Survey) for 2023 said India’s national waste processing average remains below 40%. Similarly, a 2023 report by the Centre for Science and Environment, a public interest research organization based in New Delhi, says about half of the total waste generated in the country remains uncollected.

Even when diversion tactics are being used, oversight is warranted. Watchful reporting by the Hindustan Times exposed weaknesses in the trash-sorting process.

South Korea has been credited with reducing food waste by the Korea Economic Institute of America, a think tank.

Taiwan, “with its stringent regulatory frameworks and advanced recycling technologies, generates significantly less FW [food waste] per capita compared to Malaysia and Bangladesh,” according to a 2024 academic study.

In the US, researchers found that, although five states passed laws pressing businesses to compost food waste instead of trashing it, only one state, Massachusetts, achieved a decrease.

There are many and varied strategies to keep organics out of landfills.

One option is to send organic waste to composting facilities or anaerobic digesters instead of landfills, so that much less methane is produced, with potential byproducts such as compost, biogas, or other beneficial end products.

A 2024 RMI report said: “Diverting organic waste to compost or anaerobic digestion can achieve up to 95% methane reduction efficiency when compared with landfilling, depending on operational practices, and strategies to prevent waste generation further reduce greenhouse gas emissions throughout the supply chain.” And further: “Reducing organic waste disposal also brings significant benefits to communities and ecosystems in terms of food security, soil health, and green job creation.”

Organics recycling projects, Frankiewicz acknowledged, “typically come with incremental capital costs to invest in new infrastructure, but the revenue from valorized end products (e.g., compost, biogas, digestate) can make projects economically viable and in some instances more favorable than landfilling over time, which can be passed on to consumers through lower rates.”

In addition, other beneficial changes can occur from such initiatives. Jobs can be created, according to a study by the NGO GAIA. It concluded that “zero waste approaches create orders of magnitude more jobs than disposal-based systems that primarily burn or bury waste.” Frankiewicz in his 2024 Senate testimony said: “From an economic standpoint, preventing and reducing organic waste saves consumers money and avoids the costs associated with managing discards.”

Using Gas Capture Systems

Methane emissions from landfills can be profitably captured and used as fuel.

Methane can be extracted by embedding perforated tubes into the landfill and creating a vacuum system.

The captured methane, variously called landfill gas (LFG), renewable natural gas (RNG), biomethane, or bio-gas, can be refined and then used in any number of ways. It can be burned to generate electricity for onsite use or supplied to the grid. It can be converted to liquid natural gas that can fuel vehicles, such as garbage trucks. It can be transported elsewhere by pipeline, for industrial and other uses. Because it is fuel domestically produced, it potentially reduces the need for more expensive imports.

The choices are not all black and white, however. “In some contexts,” producing renewable natural gas, “could lead to a net increase in methane emissions when used as a vehicle fuel,” according to a report by the World Resources Institute.

The use of capture systems is growing, and there is plenty of upside potential.

The US EPA reported that 61% of methane generated by landfill food waste in the US in 2023 is not captured by gas collection systems.

A 2024 assessment in India by academic experts said power generation from landfills could result in annual financial gains of US$4.7 to $13 billion. “These findings underscore the importance of implementing integrated waste management strategies that prioritize waste reduction, efficient treatment, and energy recovery from landfill gas,” wrote the authors. Savings from methane recovery were analyzed in a 2024 article in Frontiers.

A key impediment to this solution is the expense of installing capture systems, and in many places it won’t be feasible. It may be challenging for smaller landfills.

A 2022 World Health Organization report on Ghana pointed to the complications, stating, “While the landfill gas capture scenario has lower methane emissions, it would require large infrastructure investments, building new sanitary landfill capacity, and guaranteeing robust regulatory enforcement to ensure that all collected waste is diverted to sanitary landfills.” The report also discussed alternatives.

However, investors, including oil and gas companies, are looking into deals with landfills, to underwrite the cost of developing recovery systems in exchange for a share of the revenue. Oil and gas companies are investing in landfills that turn trash into clean fuel, according to an NBC News report on a Fort Wayne, Ind., landfill that is converting waste to natural gas.

Specialized companies sell the equipment. For example, Qnergy, “a leading provider of methane abatement solutions” based in the US, in 2025 announced TORCH4, “developed for small, unregulated landfills to mitigate methane emissions and gain compliance with minimal operating costs.”

A Landfill Gas Screening Tool was created by the US EPA to assist cities in assessing the potential feasibility of landfill gas energy projects.

It’s impossible to review all the options, but the increased interest in this area should provide sources. Companies looking to profit by collecting emissions could be useful sources. The comparative experiences of places using different systems could be instructive. Landfill operators could be interviewed about their options and experiences.

Operational Methods to Mitigate Emissions

Sometimes overlooked are basic landfill practices that can reduce emissions.

Waste is covered, usually daily, and the thickness and compaction of the cover affects emissions and also can increase the efficiency of capture operations. Tuning and maintenance can boost gas collection system performance. Biocovers spread across a landfill’s surface contain naturally occurring methane-eating microorganisms, which reduce emissions between 70 and 100%.

“Our modeling shows that in the short term, large methane emissions reductions will come from improvements to gas collection and cover, while organics diversion measures result in methane reductions in the long run, as it takes time for these measures to have an impact,” according to a report by the US non-profit think tank Industrious Labs.

These are complicated issues for journalists, likely to require expert help.

Government Actions

Governments have sought to reduce emissions in a variety of ways:

  • Requiring more monitoring and transparency;
  • Setting abatement goals;
  • Raising taxes and fees;
  • Incentivizing mitigation efforts;
  • Running awareness campaigns;
  • Closure of open or illegal dumpsites and conversion of open dumps to controlled dumpsites;
  • Imposing fines when emissions rise above set levels.

Governmental carrots and sticks may both be required.

A next step in India is a government proposal to make producers and others responsible for collecting and recycling the packaging waste they generate, as described in a Down to Earth article.

Environment and Climate Change Canada in 2024 issued a proposal for national minimum landfill gas standards.

In the United States, the Biden administration issued a rule in April 2024 that required “comprehensive and accurate information on landfill emissions and the efficacy of gas collection systems and destruction devices.” However, the Trump administration has signaled opposition to the rule, announcing a reconsideration of the Greenhouse Gas Reporting Program (GHGRP).

Some US state governments are active in this area. Colorado, for example, is considering earlier installation of gas collection systems and more use of technologies such as aerial monitoring and biofilters, as reported by WasteDive and Colorado News Line.

Some Signs of Progress

There are signs that solutions are reducing methane emissions from landfills.

Landfills in the US recorded their third consecutive year of declining methane emissions, dropping to 119.8 million metric tons of carbon dioxide equivalent in 2022, according to a 2024 report by the US EPA, Inventory of US Greenhouse Gas Emissions and Sinks.

In one locale, Orange County, Calif., a variety of solutions are being implemented. Waste Today reported on a successful capture program at a landfill in Iowa. In the absence of US federal leadership, states are taking the lead, Canary Media reported.

In Europe, methane emissions decreased by 45% between 1990 and 2021, and that trend is projected to continue. “[B]ased on the Member States’ projections of greenhouse gas emissions, methane emissions from the waste sector will decrease by 52% by 2050,” according to the European Environment Agency.

Summer Reading List for Data Journalists: For Those Who Believe in the Power of Storytelling with Numbers

2025-07-29 15:00:47

Data journalism has evolved beyond merely working with verified statistics; it now encompasses the integration of data with emotion, ethics, and aesthetics to foster greater transparency, fairness, and understanding in the world.

Effective data journalism demands not only robust analytical skills but also empathy, visual literacy, data literacy, strategic thinking, and ethical sensitivity. Our summer book reading list, tailored for data journalists seeking to cultivate this multifaceted skill set, extends beyond conventional technical resources.

I have been teaching data journalism for 13 years, and for the past six years, I have been teaching data visualization, data management, big data, and insights. This experience has taught me that I need to develop an interdisciplinary approach, so when sharing reading materials, I have prioritized sources that include experiences from various sectors, such as sociology, marketing, or the experiences of a data visualization engineer at a software company or a graphic designer. When compiling this list, I considered both the primary sources that are part of my reading and teaching, as well as recommendations.

As a result, these selections encompass a diverse array of intellectual fields, ranging from feminist data inquiry to art-centered data visualization, ethical dilemmas to storytelling, and scientific narratives to pedagogical facilitation. It highlights the challenges of making femicide visible through data, the role of media production accelerated by artificial intelligence, and heartfelt narratives that convey to children or those unfamiliar with data that “numbers are not something to fear.”

This reading list is designed for data journalists who not only work with data but also engage with it critically — discussing, writing, collecting, processing, and analyzing it. Each book serves as a gateway: some enhance technical skills, others refine narrative abilities, and still others provide ethical and human insights that deepen our relationship with data.

Data is not merely information; in the right hands, it evolves into freedom, justice, visibility, meaning, remembrance, restoration, and action.

This list encompasses four continents and at least eight countries, offering a global perspective on data journalism. It also incorporates methodologies from various languages — English, German, Turkish, Urdu, and Indonesian — and disciplines, including engineering, journalism, sociology, visual arts, women’s studies, artificial intelligence, and education. This transformation elevates the field of data journalism from a purely technical compilation to a culturally and intellectually enriching reading experience.

Counting Feminicide: Data Feminism in Action 

Catherine D’Ignazio (2024)

Language: English

Counting Feminicide book

In this book, academic Catherine D’Ignazio examines the relationship between data and feminism from a compelling perspective. It details how feminist data activists in Latin America systematically document femicide/feminicide (gender-based murders of women and girls), thereby redefining the conventional approach to data science through the lenses of “care,” “memory,” and “justice.” Essentially, if you’re not counted, it’s like you don’t exist! Drawing on her collaborative research project “Data Against Feminicide,” D’Ignazio demonstrates how activists, researchers, data experts, and journalists fact-check information from media, social networks, and field sources, and how they disseminate this data in a variety of creative ways, including through political narratives, public awareness-raising, and policy reform and transformation. She presents data not only as a tool for analysis but also as a form of community healing and as a collective struggle against structural inequality. Furthermore, by revealing how the system renders invisible the truths that cannot be counted — loss, suffering, and voicelessness — she explains how feminist data practice, by recording the lived experience of each individual, transforms into a demand for justice at both the individual and societal levels. The book underscores the quest for equality, bridges data science, women’s studies, social movements, and human rights practices, and offers a powerful and transformative read for readers who embrace data as a technical, emotional, ethical, and political tool.

Selena Fisk’s 192-page book serves as a useful resource for anyone who struggles with numbers or feels hesitant to engage with data. Fisk contends that data should not be feared or viewed as complicated; rather, with the right questions, straightforward explanations, and a quest for meaning, anyone can read, analyze, and enhance their decision-making. Indeed, data journalism can be particularly beneficial for those at the start of their careers. Drawing on her teaching and leadership experience, she provides practical examples that resonate with professionals in education, social services, and healthcare, illustrating that data can convey meaning not only through graphs and tables but also through narratives and human context. With its empathy-focused, non-judgmental approach, this book democratizes data literacy and offers a transformative starting point for anyone who says: “I don’t understand numbers.” By arguing that data literacy is not exclusive to analysts or those proficient in mathematics. Fisk shows how everyone can cultivate their skills in data-based thinking, production, and writing. This approach, which emphasizes “understanding and sharing data” rather than merely “speaking to data,” offers a perspective that can lead to more conscious, transparent, and effective decision-making. In this book, Fisk has crafted a warm invitation for those who shy away from data and has provided a profoundly humane roadmap for the curious.

Whitney Battle-Baptiste and Britt Rusert (Editors) (2018)

Language: English

This tome connects contemporary readers with the groundbreaking infographic works of W. E. B. Du Bois, one of America’s most significant sociologists, historians, and civil rights advocates, focusing in particular on the work he prepared for the 1900 Paris Exposition. The book charts the development of the African-American community in areas such as education, property, labor, and population through statistical data, while serving as a visual tool to document the racial injustices of the era. With striking hand-drawn diagrams, Du Bois and his team not only presented data but also did so artistically, honoring the narrative of Black Americans. Colorful graphics, circular diagrams, and creatively arranged charts take both an aesthetic and political stance, demonstrating that data visualization can be not only a technical endeavor but also an ethical and cultural form of expression. This work stands at the intersection of visual sociology, the politics of race and representation, and data art. It is a historical legacy that illuminates the past while inspiring the present and future. Even today, it deserves a place on every data journalist’s reading list.
