A New Book Dives Deep Into the Climate and Health Impacts of Gas Stoves

News Feed
Wednesday, August 14, 2024

Each year, 100,000 Americans die from coal and car pollution. And each year, 20 percent of deaths worldwide are attributable to fossil fuel use. Rob Jackson, Stanford climate scientist and chair of the Global Carbon Project, keeps a long list of statistics like these—on the devastating health impacts of fossil fuels—ready to share. “That’s 10 million senseless deaths [due to fossil fuels] when we have cleaner fuels available,” Jackson explained to Civil Eats as he prepped for the launch of his new book, Into the Clear Blue Sky: The Path to Restoring Our Atmosphere. “One reason I push the intersection between health and climate is because it reaches people who won’t otherwise pay attention to climate.” That intersection hits home in about 40 percent of U.S. kitchens, where Americans still cook over flames powered by natural gas. The week of Jackson’s book launch, many of those cooks were probably drenched in sweat, too: July 22 was the hottest day ever recorded on Earth. In the book, Jackson tells stories of measuring both the staggering greenhouse gas emissions gas stoves produce and the dangerous levels of air pollutants home cooks breathe in as they sauté and roast (even long after the burners are off). Last year, some of those measurements, published in research studies, contributed to public awareness that quickly spiraled into what multiple media outlets branded “gas stove culture wars.” (Just last week, Senator JD Vance told his supporters Vice President Kamala Harris “wants to take away your gas stoves,” which is entirely false.) But Into the Clear Blue Sky  is a solutions book written by a scientist, and Jackson approaches the phaseout of gas-powered home appliances with the same steady, measured urgency he applies to exploring decarbonizing steel and electrifying vehicles—two other important solutions in his book. Also, early on, he establishes a throughline: that the impacts of the climate crisis are unequally felt, and solutions need to be accessible and applicable to all. Jackson spoke to Civil Eats about his groundbreaking research, the pushback against policies that could speed electrification, and how writing about climate solutions—gas stove phaseouts and otherwise—has left him angry and afraid, but also hopeful. You set out to write about climate solutions, and you allotted two chapters to the food system—one on gas stoves, one on beef. Considering all the ways that climate change intersects with the food system, why those two? For a couple of reasons. In the book, I highlight the opportunities for reducing methane concentrations in the atmosphere as probably our best short-term goal for climate action. And the two largest sources of methane in the world are food: primarily cows and rice paddies, and gas appliances in our homes and buildings. We did the first studies looking at emissions from water heaters and have spent the last five years studying gas stoves—initially, purely for their greenhouse gas emissions, to see how much methane leaks into the air. We found that the leaks from gas stoves alone in the U.S. were responsible for pollution equivalent to half a million U.S. cars. But as we were going into hundreds of homes measuring methane, we started measuring indoor air pollutants like NOx [nitrogen oxide] gasses, which triggers asthma, and benzene, which is carcinogenic. That opened a whole new field of study for me, because I realized every time I turned on a burner on a gas stove or started the oven, pollution levels shot up above health benchmarks, even when I had the ventilation hood on in my house. You wrote that the U.S. Environmental Protection Agency (EPA) doesn’t include methane leakage from gas appliances in their greenhouse gas emissions estimates. Is that still true, or has your research changed things? It’s still mostly true. They do now include some emissions from gas stoves, but they don’t include the full set of emissions, including leakage. I began measuring methane from appliances in homes and buildings because it was the least-studied part of the gas supply chain, and I wanted to fill a fill a research gap there. Our research has drawn a lot of attention to the issue of gas appliances in our homes. The largest source of emissions indoors is the furnace, because it burns so much more gas. But the furnace and the water heater are required to vent directly outdoors through a chimney or a pipe. I focus a lot on gas stoves because there’s no vent. Or there’s a hood that most people don’t use—and that surveys show often isn’t effective. The levels of air pollutants you’ve measured in people’s homes are unbelievably high. In the book, you talk about how the industry knew about the health concerns more than 100 years ago, to the extent that their own experts said gas shouldn’t be used in homes without requiring hoods that vented to the outside, which didn’t happen. How much of this evidence on indoor air pollutants and the health implications is just emerging now and how much is new? It’s a fascinating question. For example, there’s 50 years of measurements on NOx pollution indoors. There were meta-analyses done in the 1990s showing that stoves increased indoor NOx levels and that the likelihood of asthma and wheezing and different health outcomes increased if you lived in a home with a gas stove. So, that knowledge was well known 30 years before I ever thought about measuring gas stoves. I think our instruments are better now, and we have a finer-scale resolution. And until we did it, no one had measured benzene emissions indoors from gas stoves. So, we’re still learning about the full set of pollutants that are generated indoors. And I think we’re learning more now about not just the emission rates but the concentrations that people actually breathe. That’s the tricky part, because what you need to know for predicting health outcomes is how high the levels are—not just in the kitchen but in the bedrooms down the hall where people spend their time and sleep. That was the biggest surprise of our studies for me—the fact that concentrations of pollutants rose so quickly in bedrooms down the hall and stayed above health benchmarks for hours after the stove was off. When you think about cooking meal after meal, day after day, month after month and these concentrations just recurring all the time in our homes . . . sometimes I think we would never willingly stand over the tailpipe of a car breathing in the exhaust, but we willingly stand over a gas stove and breathe the same pollutants. Have you done any of this research in restaurants? We are doing that right now, literally. I have a part of my lab up in Pittsburgh doing measurements. We’ve done some in the Bay Area. We’re doing some in the Midwest, and we’re going to go to Washington, D.C. this summer and do some more. Generally, [commercial] kitchens have industrial hoods, which are much better. However, they also have many more burners. And they have pilot lights, which are the most inefficient way that we burn. So, I worry about exposures where the concentration is building up at night after the restaurant closes and the hoods are off and these pilot lights are burning. I worry more about small kitchens . . . somewhere where maybe the ventilation is not so good. We’re really trying to understand the risks in kitchens and, frankly, to do it more positively. We’re trying to work with chefs to promote the benefits of electrification. There’s an increasing number of chefs willing to speak out and say, “Yes, I can cook with electricity and there’s no reason not to switch now.” In terms of electrification, you talk a lot in the book about how climate solutions need to be accessible to everyone. Switching to induction from gas can be really costly. How do you see the transition becoming possible for people at all income levels? I do think the cost will come down over time. But I think of climate solutions [as having] two flavors: One is to use less of whatever it is that emits fossil fuels. The other is to decarbonize whatever infrastructure is left. And we can’t really cook less, so that’s not a realistic solution set for our homes. So, I think we need to favor reach codes that require future construction to be all electric. Governor [Kathy] Hochul and the Assembly and Senate in New York passed the country’s first state-level bill requiring new homes and buildings be all-electric by 2026. Those bills make sense to me, because every time we plumb a new house or new building with gas infrastructure or fossil fuel infrastructure, we lock in greenhouse gases for decades to come. I don’t suggest that we need to go into every home and rip people’s stoves off the walls. We need an orderly transition, and the place to do that is when our stoves reach the end of their lifetime, to switch them out. Since I am fortunate and relatively wealthy, I chose to replace my gas stove with an induction stove before the end of its lifetime because I could. But the hundreds of homeowners we sample in Bakersfield and lower-income neighborhoods, they don’t have that option, and even if they can afford it, they rent. So, I worry the most about people in lower-income communities. There’s also been a lot of pushback. Are you optimistic about these electrification laws moving forward? The industry is powerful. The reach codes that Berkeley passed have been overturned. There were 100 cities and counties in California that had passed similar reach codes, and most of those are now moot. States like New York have taken a different approach, and I’m optimistic that states that want to act will find a way to incentivize the transition to electric appliances. But there have now been a couple of dozen states that have passed preemption laws to make such codes illegal. Though there’s tremendous pushback, I think induction stoves will win eventually, because they’re a better product. They’re more efficient. A child can’t burn their hand. But [with climate], winning slowly is the same as losing, as Bill McKibben likes to say. On that note, my editor suggested I ask you about what gives you hope, and I felt myself having an emotional reaction. Like, “I don’t care about hope! I care about what’s possible. Brass tacks. What can be done—or not—to move the needle?” But you use the word hope a lot in the book, so I thought I should ask: Why? I would say that hope and optimism are muscles that we need to exercise. My first homework assignment in any class is for students to go home and research things in the environment that are better today than they were 50 years ago. That list is long. It’s lifespan and childhood mortality. It’s water and air quality. It’s a decline in global poverty, despite the injustices that remain. Then there’s a long list of targeted regulations that have saved us money and made us healthier. The phaseout of leaded gasoline has literally made us smarter and made lead levels in our kids’ blood drop 95 percent. There’s the Montreal Protocol that saved billions of cases of skin cancers and cataracts. And there’s my favorite example—the Clean Air Act—that saves 100,000 American lives a year, a bipartisan bill at a 30-fold return on investment. So, I think by acknowledging past successes we make future successes in climate more likely, because we can see a path to a better future. And I guess I believe strongly that it’s very easy in my world to sink only into the latest statistics of drought and disasters—but it doesn’t seem to motivate people. So, it’s a sort of hope grounded in facts and history. Yes, but the undercurrent is there, which is, you know, I’m afraid and angry, because we’ve wasted decades. We’ve sprinted right to 1.5°C—something that people thought was unfathomable 20 years ago—and we seem to be sprinting towards 2°C. So yes, I’m hopeful, but I’m also angry and afraid for all of us. Given the urgency, do you think that this upcoming election could partially determine whether catastrophic outcomes are locked in? I’m an environmental scientist, and at this point in my life, there’s only one party that seems to take climate and the environment seriously. It wasn’t always that way. My biggest regret is how politicized and polarized the environment has become. Republican administrations created the EPA and signed the Montreal Protocol. Even Margaret Thatcher, she once said something like, “We have treated the atmosphere like a dust bin.” She of course backtracked later in her career, but she was a chemist and scientist, and she understood. I regret the fact that we are in a place where a Republican who mentions climate gets defeated in a primary by someone farther to the right. I don’t want to pick parties, but I’m deeply concerned about this election. We can’t afford another administration undoing climate rules. It isn’t just for the climate. It’s killing millions of people around the world and hundreds of thousands of Americans. Let’s be frank about it.

Are Dairy Digesters the Renewable Energy Answer or a ‘False Solution’ to Climate Change? $2 Billion for Farmer Discrimination. On July 31, Secretary of Agriculture Tom Vilsack announced that the U.S. Department of Agriculture (USDA) had successfully distributed more than $2 billion to 43,000 farmers who had experienced discrimination while attempting to secure USDA loans. The announcement marked a historic moment in a long saga. Farmers have alleged discrimination in the agency’s loan programs for decades, and multiple lawsuits have been filed over the years by women, Indigenous, and Black farmers who said they were treated differently when applying for loans, driving many out of business. In 2020, lawmakers set aside $4 billion specifically to compensate Black farmers for race-based discrimination, but the program was thrown out in the wake of lawsuits, many of which were filed by Republican officials who alleged discrimination against white farmers. So when Democrats passed the Inflation Reduction Act, they authorized a new, race-neutral fund that would compensate any farmer who alleged discrimination based on race, ethnicity, gender, and other factors. During a press call announcing the news, Vilsack said the agency received 58,000 applications and ultimately approved 43,000. While the agency could not compensate farmers for losses or pain endured, he said, “I think it represents USDA acknowledging and responding to reported discrimination.” Vilsack could not provide statistics on how many of the individuals who received funding were Black farmers, but said that analysis may become available in the future. He also pointed out that the states with the most farmers awarded funding were Mississippi and Alabama. In addition to the payments, he said the agency has been working to root out and prevent future discrimination and break down barriers to access within its loan programs with, for example, “new processes that reduce the need for human discretion in loan decision-making.” Many Democrats in Congress and advocacy organizations released statements applauding the USDA’s progress on the issue. “Today marks an important milestone for USDA and for our collective efforts to hold the Department accountable in addressing a history of acts of discrimination against perpetually marginalized agricultural producers and their communities,” said Michelle Hughes, Co-Executive Director of the National Young Farmers Coalition, in a press release. The coalition was one of the cooperating organizations, along with others like the Federation of Southern Cooperatives, that helped the USDA get the word out to farmers about the application process.

According to a report published last week by the Midwestern Prairie Rivers Network (PRN), herbicides sprayed primarily on row crops in Illinois are drifting far from targeted fields, damaging trees and other plant life. Researchers at PRN monitored symptoms of pesticide drift—such as curled leaves—and collected tissue samples from plants over six years. They found symptoms of drift during 677 out of 679 total visits to nearly 300 sites. Of 127 tissue samples taken from trees and other plants, 90 percent contained herbicide residues. Herbicides detected included 2,4-D, atrazine, dicamba, glyphosate, and seven others. Many of the sites where researchers documented incidents of drift were more than 500 feet from the likely source of exposure, suggesting the chemicals are drifting significant distances. “Our monitoring and tissue sampling program indicates that current legal safeguards/protections and regulatory efforts are inadequate at protecting people and the environment from herbicide drift,” the researchers wrote. At a press conference for the release of the report, co-author Kim Erndt-Pitcher said the results pointed to the fact that herbicides are playing a significant role in the decline of tree health across the state, and residents and farmers expressed concerns about potential risks to animals and their families’ health. Patsy Hopper, an organic farmer and landowner south of Urbana, Illinois, said her land long produced a bounty of fruits and vegetables. At one point in time, she remembered harvesting 50 gallons of cherries in a season. “In the past few years, we’ve hardly had a harvest because of pesticide drift. The trees are dying,” she said. “This year, we had enough cherries for one pie.” Read More: Beyond Damaging Crops, Dicamba Is Dividing Communities EPA Weakens Safeguards for Weed Killer Atrazine, Linked to Birth Defects Farm-State Veep. On August 6, Vice President and Democratic presidential candidate Kamala Harris chose Tim Walz as her running mate, catapulting agriculture and other food issues into the 2024 presidential election in a new way. As a member of the House of Representatives, Walz served on the Agriculture Committee. There, he played a role in three farm bill cycles, sponsoring various proposals focused on expanding on-farm conservation efforts and supporting beginning farmers and ranchers. As Governor of Minnesota, Walz has advocated for biofuels, a key priority of commodity ag groups, and local advocates for small farms say he fought consolidation to keep more farmers on the land. He also championed and ultimately signed into law a universal school meals program in the state. Read more: States Are Fighting to Bring Back Free School Meals This Farm Bill Really Matters.

The trees are dying,” she said. “This year, we had enough cherries for one pie.”

Farm-State Veep. On August 6, Vice President and Democratic presidential candidate Kamala Harris chose Tim Walz as her running mate, catapulting agriculture and other food issues into the 2024 presidential election in a new way.

As a member of the House of Representatives, Walz served on the Agriculture Committee. There, he played a role in three farm bill cycles, sponsoring various proposals focused on expanding on-farm conservation efforts and supporting beginning farmers and ranchers.

As Governor of Minnesota, Walz has advocated for biofuels, a key priority of commodity ag groups, and local advocates for small farms say he fought consolidation to keep more farmers on the land. He also championed and ultimately signed into law a universal school meals program in the state.

Climate Scientists Raise a Middle Finger to Trump’s Censorship Efforts

This story was originally published by Inside Climate News and is reproduced here as part of the Climate Desk collaboration. Researchers across the United States and the world who raced to protect climate data, public reports and other information from the Trump administration’s budget cuts, firings, and scrubbing of federal websites are launching their own climate information portals. A group of scientists and other experts who formerly worked for the National Oceanic and Atmospheric Administration recently launched Climate.us, where they eventually hope to replicate much of the public-oriented climate content from Climate.gov.  In a parallel effort, two major scientific institutions, the American Geophysical Union and the American Meteorological Society, have started soliciting studies for a special “Climate Collection” to maintain momentum on the work that was already under way on a Congressionally mandated 6th National Climate Assessment, due in 2028, before all the scientists working on the report were fired and cabinet-level team that led the effort disbanded. “It’s unbelievable…We were literally forced to word search our own website and take down articles because they didn’t want to read the word ‘equity’ “ The new efforts demonstrate how difficult it is to erase or obscure climate science from the public in an era when thousands of scientists and computers around the world are continuously calculating and measuring climate and greenhouse gas emissions. Other science rescue efforts have focused on preserving those data sets, but the public-facing portals are also important, experts said. Current efforts by the US government to make it harder for people to get scientific information are a clear-cut case of censorship, said Haley Crim, currently a climate solutions researcher at MIT and one of the leaders of an effort to restore important climate information that officials in the Trump administration purged from federal websites. Along with significant funding and personnel cuts to various federal climate programs and other scientific efforts, some scientists report facing increased harassment and threats online. Others worry that misleading, inaccurate and potentially dangerous misinformation is being posted on official government websites. Gaining traction for new climate websites can be a challenge in a world filled with misleading and false scientific information, but the latest efforts have endorsements from leading scientists and scientific institutions. And the researchers working on the science preservation and restoration efforts say that, in the long run, the projects may result in new ways to store and share scientific information, and perhaps even better ways to make that information more relevant to the growing number of people experiencing deadly and disruptive climate impacts in the US and around the world.  During her last few months working on the Climate.gov website, Crim said she was ordered to remove articles mentioning diversity and other terms identified by political appointees. The altered version of the website remains online, but its future beyond the end of this year is uncertain.  A NOAA spokesperson said that changes to Climate.gov were made in compliance with an executive order, and that all research products from climate.gov will be relocated to Noaa.gov to “centralize and consolidate resources.” “It’s unbelievable, and it is censorship, and I think people were afraid to say that for a long time,” Crim said. “We were literally forced to word search our own website and take down articles because they didn’t want to read the word ‘equity’, or other related terms.” The administration could still use Climate.gov to publish misleading information, like a recent debunked climate report from Trump’s DOE. On top of the censorship, Crim said she and others working on the new website fear that the Trump administration could lash out at them or their institutions, but she said she won’t be intimidated. “There’s no other option for me,” she said. “I can’t sit back and watch this stuff be taken down because someone didn’t like it. It is state-of-the-art climate information and I’m not just going to let that go away.” Any mentions of climate justice were also purged, said former Climate.gov editor Rebecca Lindsey, who is now working on the effort to restore the deleted information on the new website, Climate.us.  So far, a handful of people are coordinating the effort publicly, with dozens of others volunteering behind the scenes. The long-term goal is to ensure there is as complete a backup as possible, including censored material, if Climate.gov goes offline. “They removed anything about trying to increase diversity in the sciences, and the fact that the impacts of human-caused climate change are going to be disproportionately felt by people who are already marginalized,” Lindsey said, adding that the team wants to revive that potentially life-saving information. Through mid-September, crowdfunding efforts have enabled the volunteers to launch their new website and, in a big step, to post the Fifth National Climate Assessment.  The NCA5, published in 2023, is the most comprehensive federal report on human-caused warming and its impacts and serves as a critical resource for communities facing wildfires, rising sea levels and other climate-related challenges. It was relegated to an archival website in June when the administration shut down the interagency US Global Change Research Program, which had a congressional mandate to produce the report. In a worst-case scenario, Lindsey added, the administration could use the popular Climate.gov portal to publish deliberately misleading information, like a recent debunked climate report from the US Department of Energy. To establish the new website’s credibility, the team plans to partner with authoritative institutions, such as the World Meteorological Organization and the American Meteorological Society, and recruit an independent science advisory panel for expert review and oversight, she said. Parallel to the efforts to re-create the Climate.gov information portal, the AGU and the AMS are working to ensure that climate information relevant to the United States’ interests is being properly cataloged in a format that could be used in a future national climate assessment. Their project compensates for the potential discontinuation of work on a new congressionally mandated National Climate Assessment scheduled for 2028. The Trump administration defunded the interagency team and dismissed the scientists working on the assessment in April. A federal task force coordinated the National Climate Assessment, but the new US climate collection will be more of a grassroots project, as the peer-reviewed contributions help define its shape.  Working “outside the federal fence” could open avenues for climate communications that weren’t previously an option.” “One of the things that we in the broader science community can do in this moment is do what we do best, and that’s peer-reviewed, rigorous science,” said Costa Samaras, director of the Scott Institute for Energy Innovation and trustee professor of civil and environmental engineering at Carnegie Mellon University, who is helping to coordinate the collection. “Information about how climate affects communities and resources is essential for both public understanding and for public and private decision making,” he said.  The collection can be a beacon for the scientific community to submit “high-quality, rigorous scientific research around climate that can be peer-reviewed and widely shared for free,” he said, “in a way that helps, our broader understanding of these issues, especially as climate impacts accelerate.” He said some of the research likely will focus on questions like where extreme rains will lead to flooding in coming decades, and where sea level rise may take unexpectedly big bites out of coastal communities, as well as studies looking at overall ecosystem impacts and community impacts, with an eye toward how climate impacts “disproportionately affects marginalized communities, both here and around the world,” he said.  Co-organizer Bob Kopp, a climate researcher at Rutgers University who has also participated in several other major national and international climate assessments, said there has been significant research on systemic climate impacts that could be part of the collection, including effects on insurance and real estate markets, and how climate impacts strain municipal health infrastructure. Additionally, he said assessments of carbon dioxide removal and other negative-emissions technologies would be useful. There are, for example, a lot of ways to think about climate impacts and climate solutions that “relate to the education sector, the IT sector, or the legal system. I personally would love to see things that haven’t been assessed as much,” he said. “New synthesis papers could really lay the groundwork for future assessments.” Lindsey, the former NOAA contractor now working on the new public climate information portal, climate.us, said that working “outside the federal fence” could open avenues for climate communications that weren’t previously an option for the federal agency, including posting information about global warming and carbon dioxide mitigation, which was not part of the mission of the climate.gov website, she said. “We see this as an opportunity to diversify our support, to get out from under potential political interference,” she said.

The rich must eat less meat

Here’s a sobering fact: Even if the entire world transitions away from fossil fuels, the way we farm and eat will cause global temperatures to rise 1.5 degrees Celsius above preindustrial levels — the critical threshold set in the Paris Climate Agreement.

Here’s a sobering fact: Even if the entire world transitions away from fossil fuels, the way we farm and eat will cause global temperatures to rise 1.5 degrees Celsius above preindustrial levels — the critical threshold set in the Paris Climate Agreement. The further we go above that limit, the more intense the effects of climate change will get. The good news is that we know the most effective way to avert catastrophe: People in wealthier countries have to eat more plant-based foods and less red meat, poultry, and dairy. Such a shift in diets — combined with reducing global food waste and improving agricultural productivity — could cut annual climate-warming emissions from food systems by more than half. That’s one of the main findings from a new report by the EAT-Lancet Commission, a prestigious research body composed of dozens of experts in nutrition, climate, economics, agriculture, and other fields.   The report lays out how agriculture has played a major role in breaking several “planetary boundaries”; there’s greenhouse gas emissions — of which food and farming account for 30 percent — but also deforestation and air and water pollution. The new report builds on the commission’s first report, published in 2019 — an enormous undertaking that examined how to meet the nutritional needs of a growing global population while staying within planetary boundaries. It was highly influential and widely cited in both policy and academic literature, but it was also ruthlessly attacked in an intensive smear campaign by meat industry-aligned groups, academics, and influencers  — a form of “mis- and disinformation and denialism on climate science,” Johan Rockström, a co-author of the report, said in a recent press conference.   Our food’s massive environmental footprint stems from several sources: land-clearing to graze cattle and grow crops (much of them grown to feed farmed animals); the trillions of pounds of manure those farmed animals release; cattle’s methane-rich burps; food waste; fertilizer production and pollution; and fossil fuels used to power farms and supply chains. But this destruction is disproportionately committed to supply rich countries’ meat- and dairy-heavy diets, representing a kind of global dietary inequality. “The diets of the richest 30% of the global population contribute to more than 70% of the environmental pressures from food systems,” the new report reads.  To set humanity on a healthier, more sustainable path, the commission recommends what they call the Planetary Health Diet, which consists of more whole grains, fruits, vegetables, legumes, and nuts than what most people in high- and upper-middle-income countries consume, along with less meat, dairy, and sugar. But in poor regions, like Sub-Saharan Africa and South Asia, the commission recommends an increase in most animal products, as well as a greater variety of plant-based foods. If globally adopted, this plant-rich diet would prevent up to 15 million premature deaths each year. (The commission notes that the diet is a starting point and should be adjusted to accommodate individual needs and preferences, local diets, food availability, and other factors.) It would also reshape the global food industry, resulting in billions of fewer land animals raised for meat each year and a significant increase in legume, nut, fish, and whole grain production (while many regions currently eat more fish per capita than the report recommends, total global fish production would increase over time under the report’s parameters to meet demand from growing populations).  Rather than expecting billions of people to actively change how they eat, the commission recommends a number of policies, including reforming school meals, federal dietary guidelines, and farming subsidies; restricting marketing of unhealthy foods; and stronger environmental regulations for farms. If EAT-Lancet’s main recommendations were to be implemented, shifting to plant-rich diets would account for three-quarters of the major reduction in agricultural emissions. Other recommendations, like improving crop and livestock productivity and reducing food waste, are important, but their impact would be much smaller than diet change, contributing a quarter of expected agricultural emissions reductions.   The report is thorough and nuanced, but its conclusions aren’t exactly novel; for the past two decades, scientists have published a trove of studies on the environmental impact of agriculture and have landed on the same takeaways — especially that rich countries must shift their diets to be more plant-based. But that message has, with few exceptions, failed to incite action by governments and food companies, or even the environmental movement itself.  That failure can be explained, in part, by the meat industry’s aggressive, denialist response to the scientific consensus on meat, pollution, and climate change. The meat industry’s anti-science crusade, briefly explained In the 2010s, it seemed possible that the US and other wealthy countries might adopt more plant-based diets: Some researchers and journalists predicted that better plant-based meat products, from companies like Beyond Meat and Impossible Foods, could disrupt the conventional meat industry; governments in several countries recommended more plant-based diets; and campaigns like Meatless Monday and Veganuary had gained momentum. This story was first featured in the Processing Meat newsletter Sign up here for Future Perfect’s biweekly newsletter from Marina Bolotnikova and Kenny Torrella, exploring how the meat and dairy industries shape our health, politics, culture, environment, and more. Have questions or comments on this newsletter? Email us at futureperfect@vox.com! These trends posed an existential threat to the livestock sector, and it was in this environment that the first EAT-Lancet report was published. It made international headlines, but the backlash was swift: The meat industry coordinated an intense and successful online backlash operation. Shortly after, the World Health Organization pulled its support for an EAT-Lancet report launch event. One report author said she was “overwhelmed” with “really nasty” comments, and another said he faced career repercussions.   In the years that followed, the industry ramped up its efforts to steer policy and narratives in its favor and out of line with scientific consensus:  From 2020 to 2023, European meat companies and industry groups successfully weakened EU climate policy.  The number of delegates representing the meat industry at the UN’s annual climate change conference tripled from 2022 to 2023. A 2023 United Nations report on reducing climate emissions in the food system omitted meat reduction as an approach, which some environmental scientists found “bewildering” (this could be due to intense meat industry pressure imposed on UN officials). The industry spent a great deal of money attacking plant-based meat companies, downplaying meat’s environmental impact, cozying up to environmental nonprofits, and spreading the narrative that voluntary, incremental tweaks to animal farming methods are sufficient — not regulations and diet shifts. Now, as global ambitions to reduce meat consumption and livestock production have shriveled in the face of intense pressure from industry, the new EAT-Lancet report feels more important, and also more vulnerable, than ever. But I worry most of the climate movement is only too eager to go along with the industry’s preferred approaches and narratives because many environmental advocates, like virtually everyone else across society, don’t want to accept that meat reduction in richer countries is non-negotiable. That much was evident when I attended last month’s Climate Week NYC, the world’s second-largest climate change gathering. The meat conversation missing from Climate Week The annual event brings together some 100,000 attendees for more than 1,000 events across the city. This year, only five events centered on plant-based food as a solution to climate change. In other words, what environmental scientists consider to be the most effective solution to addressing around 16 percent of greenhouse gas emissions received around 0.5 percent of the week’s programming. At the same time, the meat and dairy sectors managed to establish a large presence at Climate Week’s food and agriculture programs.  The Protein Pact, a coalition of meat and dairy companies and trade groups, sponsored a panel put on by the climate events company Nest Climate Campus, which listed one of Protein Pact’s representatives — who spoke on its main stage — as a “climate action expert.” The Protein Pact is also a leading sponsor of Regen House, an agriculture events company that hosted several days of Climate Week programming. Meanwhile, the Meat Institute — the founder of the Protein Pact — sponsored events put on by Food Tank, a nonprofit think tank. It would be one thing if the Protein Pact were open to compromise on environmental regulation and spoke more honestly about their industries’ climate impact. But many of its members lobby against environmental action and downplay the industry’s environmental footprint. Some even participated in the campaign against EAT-Lancet’s first report. Given this track record, it’s hard to see the industry’s presence at Climate Week as anything but a reputation laundering effort.  The Meat Institute, Food Tank, Nest Climate Campus, and Regen House didn’t respond to requests for comment.  This dynamic — in which meat industry narratives are welcomed and legitimized in much of the environmental movement — has contributed to public ignorance of the industry’s pollution and its underreporting in the news media.  According to a new, exclusive analysis from the environmental nonprofit Madre Brava, only 0.4 percent of climate coverage in US, UK, and European English-language news outlets mention meat and livestock. Madre Brava also polled US and Great Britain residents and found they underestimated animal agriculture’s environmental impact.  Finding hope in Climate Week’s Food Day   A lot of climate news coverage — including this story — is depressing and fatalistic, so I’ll try to end on a hopeful note. I felt a bit of this strange emotion at Food Day, a Climate Week event organized by Tilt Collective, a philanthropic climate foundation advocating for plant-rich diets. I’ve attended a lot of conferences on shifting humanity toward more plant-based diets, and I usually end up seeing a lot of the same people. That wasn’t the case at Food Day. There were a lot of unrecognizable faces — people from climate foundations, environmental nonprofits, government agencies, and universities — all eager to take on this big, challenging, fascinating problem, however intimidating it may be.  The following day, I attended a climate journalism event hosted by Sentient, a nonprofit news outlet that covers meat and the environment. Similarly, the room was packed with journalists and communications professionals, most of whom don’t cover these issues but were there to learn about them. These events — and the few others that centered on plant-based foods — were overshadowed by the meat industry’s Climate Week presence. But the events did suggest that there’s growing acceptance that we must change the way we eat, and that time is running out to do something about it. That’s not enough, but it’s better than nothing. Given the state of our politics and environmental policy, that’s maybe the best one can hope for.  

A Recipe for Avoiding 15 Million Deaths a Year and Climate Disaster Is Fixing Food, Scientists Say

Scientists are presenting new evidence that the worst effects of climate change can’t be avoided without a major transformation of food systems

Their conclusion: Without substantial changes to the food system, the worst effects of climate change will be unavoidable, even if humans successfully switch to cleaner energy.“If we do not transition away from the unsustainable food path we’re on today, we will fail on the climate agenda. We will fail on the biodiversity agenda. We will fail on food security. We’ll fail on so many pathways,” said study co-author Johan Rockström, who leads the Potsdam Institute for Climate Impact Research.The commission's first report in 2019 was regarded as a “really monumental landmark study” for its willingness to take food system reform seriously while factoring in human and environmental health, said Adam Shriver, director of wellness and nutrition at the Harkin Institute for Public Policy and Citizen Engagement. Key points from the latest report: A ‘planetary health diet’ could avert 15 million deaths every year The first EAT-Lancet report proposed a “planetary health diet” centered on grains, fruits, vegetables, nuts and legumes. The update maintains that to improve their health while also reducing global warming, it's a good idea for people to eat one serving each of animal protein and dairy per day while limiting red meat to about once a week. This particularly applies to people in developed nations who disproportionately contribute to climate change and have more choices about the foods they eat.The dietary recommendations were based on data about risks of preventable diseases like Type 2 diabetes and cardiovascular disease, not environmental criteria. Human and planetary health happen to be in alignment, the researchers said.Rockström said it may seem “boring” for an analysis to reach the same conclusion six years later, but he finds this reassuring because food science is a rapidly moving field with many big studies and improving analytics.Food is one of the most deeply personal choices a person can make, and “the health component touches everyone’s heart,” Rockström said. While tackling global challenges is complicated, what individuals can do is relatively straightforward, like reducing meat consumption without eliminating it altogether.“People associate what they eat with identity” and strict diets can scare people off, but even small changes help, said Emily Cassidy, a research associate with climate science nonprofit Project Drawdown. She wasn’t involved with the research. Our food choices could push the planet past a tipping point The researchers looked beyond climate change and greenhouse gas emissions to factors including biodiversity, land use, water quality and agricultural pollution — and concluded that food systems are the biggest culprit in pushing Earth to the brink of thresholds for a livable planet.The report is “super comprehensive” in its scope, said Kathleen Merrigan, a professor of food systems at Arizona State University who also wasn’t involved with the research. It goes deep enough to show how farming and labor practices, consumption habits and other aspects of food production are interconnected — and could be changed, she said. “It’s like we’ve had this slow awakening to the role of food” in discussions about planetary existence, Merrigan said. Changing worldwide diets alone could lead to a 15% reduction in greenhouse gas emissions from agriculture, because the production of meat, particularly red meat, requires releasing a lot of planet-warming gases, researchers concluded. Increased crop productivity, reductions in food waste and other improvements could bump that to 20%, the report said.Cassidy said that if the populations of high- and middle-income countries were to limit beef and lamb consumption to about one serving a week, as recommended in this latest EAT-Lancet report, they could reduce emissions equal to Russia's annual emissions total. Incorporating justice in an unequal world Meanwhile, the report concludes that nearly half the world's population is being denied adequate food, a healthy environment or decent work in the food system. Ethnic minorities, Indigenous peoples, women and children and people in conflict zones all face specific risks to their human rights and access to food.With United Nations climate talks around the corner in November, Rockström and other researchers hope leaders in countries around the world will incorporate scientific perspectives about the food system into their national policies. To do otherwise “takes us in a direction that makes us more and more fragile,” he said.“I mean both in terms of supply of food, but also in terms of health and in terms of stability of our environments,” Rockström said. “And this is a recipe to make societies weaker and weaker.”The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Study Shows the World Is Far More Ablaze Now With Damaging Fires Than in the 1980s

A new study shows that the world's most damaging wildfires are happening four times more often now compared to the 1980s

WASHINGTON (AP) — Earth’s nastiest and costliest wildfires are blazing four times more often now than they did in the 1980s because of human-caused climate change and people moving closer to wildlands, a new study found.A study in the journal Science looks at global wildfires, not by acres burned which is the most common measuring stick, but by the harder to calculate economic and human damage they cause. The study concluded there has been a “climate-linked escalation of societally disastrous wildfires.”A team of Australian, American and German fire scientists calculated the 200 most damaging fires since 1980 based on the percentage of damage to the country's Gross Domestic Product at the time, taking inflation into account. The frequency of these events has increased about 4.4 times from 1980 to 2023, said study lead author Calum Cunningham, a pyrogeographer at the Fire Centre at the University of Tasmania in Australia. “It shows beyond a shadow of a doubt that we do have a major wildfire crisis on our hands,” Cunningham said.About 43% of the 200 most damaging fires occurred in the last 10 years of the study. In the 1980s, the globe averaged two of these catastrophic fires a year and a few times hit four a year. From 2014 to 2023, the world averaged nearly nine a year, including 13 in 2021. It noted that the count of these devastating infernos sharply increased in 2015, which “coincided with increasingly extreme climatic conditions.” Though the study date ended in 2023, the last two years have been even more extreme, Cunningham said.Cunningham said often researchers look at how many acres a fire burns as a measuring stick, but he called that flawed because it really doesn't show the effect on people, with area not mattering as much as economics and lives. Hawaii's Lahaina fire wasn't big, but it burned a lot of buildings and killed a lot of people so it was more meaningful than one in sparsely populated regions, he said.“We need to be targeting the fires that matter. And those are the fires that cause major ecological destruction because they’re burning too intensely,” Cunningham said. But economic data is difficult to get with many countries keeping that information private, preventing global trends and totals from being calculated. So Cunningham and colleagues were able to get more than 40 years of global economic date from insurance giant Munich Re and then combine it with the public database from International Disaster Database, which isn't as complete but is collected by the Catholic University of Louvain in Belgium.The study looked at “fire weather” which is hot, dry and windy conditions that make extreme fires more likely and more dangerous and found that those conditions are increasing, creating a connection to the burning of coal, oil and natural gas.“We’ve firstly got that connection that all the disasters by and large occurred during extreme weather. We’ve also got a strong trend of those conditions becoming more common as a result of climate change. That’s indisputable,” Cunningham said. “So that’s a line of evidence there to say that climate change is having a significant effect on at least creating the conditions that are suitable for a major fire disaster.”If there was no human-caused climate change, the world would still have devastating fires, but not as many, he said: “We’re loading the dice in a sense by increasing temperatures.”There are other factors. People are moving closer to fire-prone areas, called the wildland-urban interface, Cunningham said. And society is not getting a handle on dead foliage that becomes fuel, he said. But those factors are harder to quantify compared to climate change, he said."This is an innovative study in terms of the data sources employed, and it mostly confirms common sense expectations: fires causing major fatalities and economic damage tend to be those in densely populated areas and to occur during the extreme fire weather conditions that are becoming more common due to climate change," said Jacob Bendix, a geography and environment professor at Syracuse University who studies fires, but wasn't part of this research team.Not only does the study makes sense, but it's a bad sign for the future, said Mike Flannigan, a fire researcher at Thompson Rivers University in Canada. Flannigan, who wasn't part of research, said: "As the frequency and intensity of extreme fire weather and drought increases the likelihood of disastrous fires increases so we need to do more to be better prepared."The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.
