This week, world leaders gather in Baku, Azerbaijan for the 29th annual United Nations Climate Change Conference, known as COP29. Last year’s global climate conference broke new ground as the first to tackle greenhouse gas emissions from food, with over 100 countries signing a key declaration to deliver change in their food sectors by 2025. Food systems are responsible for a third of global emissions, mostly driven by meat, especially beef. Yet even as a chorus of researchers repeatedly stress the urgency of fixing our broken food systems, only a fraction of the countries who pledged support have made any progress.

Many Countries Still Need to Update Climate Plans, Despite Pledges

At COP28, 160 countries signed on to the UAE Declaration on Sustainable Agriculture, Resilient Food Systems and Climate Action. These countries play a significant role — the 160 make up 70 percent of farmers and 80 percent of emissions from agriculture. A key point of the declaration: the countries committed to adding agriculture and food systems into their national climate plans — also known as “Nationally Determined Contributions” (NDCs). In other words, the agreement promised a concrete commitment to reduce food-related emissions.

Yet progress has been slow. Based on estimates, there are roughly just 40 countries on track to have a revised NDC in time for COP30 in Belém, Brazil next year, Edward Davey, a senior advisor for The Food and Land Use Coalition at the World Resources Institute (WRI), tells Sentient. That means 120 countries haven’t done any work to incorporate food into national climate plans so far.

While Davey says he is “very proud” of what was achieved at COP28 — calling it “a privilege to be involved in a supporting role to the UAE government as it brokered the food declaration” — he also expressed concern: “we do very much need to deliver on that declaration,” he wrote to Sentient in a subsequent email, stressing the critical importance of all 160 countries bringing revised NDCs to Brazil.

One country that has signaled they will bring a revised NDC to this year’s COP is the United Kingdom. The UK cannot possibly meet its net zero goals by 2035 and beyond if it doesn’t address diet shifts, Davey says.

And this isn’t just the case for the UK. Researchers at the World Resources Institute have warned that Global North countries cannot meet their international climate commitments without making dietary change — that is, shifting to more plant-forward diets — part of the solution.

For his part, Davey has recommended “forcefully” to the UK Government that its revised national climate plan should include solutions that address the way we farm and the way we eat. Davey cites strategies like better land management, changes to feed, reducing herd sizes, reducing food loss and waste precision breeding, among others. But dietary change — “people of the UK eating less meat per capita” — has to be in the mix too, he says.

There are obvious challenges. Shifting diets and the politics of meat consumption is a contentious subject in the UK, just as it is in the United States. And yet, meat consumption in the Global North plays a massive role in driving global emissions.

There are roughly 20 Global North countries –– including the UK and United States –– that contribute the majority of global agricultural and land use emissions, Davey says. “I think the UAE Declaration will succeed or fail [depending on] whether those 20 or so countries come back to Belém next year with a serious, quantifiable goal of food [and land use] management.”

At COP28, food system pledges also came from businesses and foundations. More than $7 billion was allocated last year from the UAE, the Bill and Melinda Gates Foundation, the Bezos Earth Fund among others. Jeff Bezos’ foundation committed $57 million into climate food solutions such as reducing methane emissions from livestock. Further, more than 200 non-state actors, including businesses, financial institutions and farmers, signed up to the a UN Call to Action to transform food systems. Large food companies like Nestle and Danone were also signatories.

The United Nations Roadmap Faces Delays and Scrutiny

The UN’s Food and Agriculture Organization (FAO) announced a three-part roadmap for food systems at last year’s conference — aimed at curbing food-related emissions while also addressing global food security concerns. The UN has predicted the world’s population will hit 9.7 billion by the year 2050, so an ongoing global food system challenge is figuring out how to feed nearly 10 billion people without making climate pollution even worse.

The roadmap is supposed to illuminate a path forward — a way for countries to mesh food system change with climate and health goals.

Here too, however, progress has stalled. The full version of the first part of the roadmap has been very delayed and the current “brief” version has also drawn criticism. Experts from the U.S., Brazil and Norway published a comment in Nature earlier this year critiquing the roadmaps various “missed opportunities for greenhouse gas emissions reductions,” among other issues. The guidelines on how to sustainably increase productivity in the Global South, while still protecting the environment, has also been left ambiguous, notes Beatriz Luraschi, a policy analyst at the European Climate Foundation.

Another setback to the roadmap was a letter to the FAO signed by more than 100 academics, calling for a controversial livestock “Pathways” report published at COP28 to be retracted over unclear and inaccurate methods. They called for the release of the roadmap to be “delayed until the FAO has engaged in serious dialogue with experts and civil society in a reflective process to assess what went wrong in the Pathways report,” as well as an overhaul of the FAO’s internal review processes.

That Pathways report seemingly promoted growing the livestock industry while ignoring emissions. The authors of a study mentioned in the report also spoke out separately, saying the FAO report “distorted” their research and underestimated the climate impact of reducing meat consumption.

These criticisms “cast a shadow over the roadmap,” says Davey, who is hopeful for the roadmap’s next installment.

The first two parts of the roadmap — both global and regional “pathways” — are due to be published at COP29. However, so far there has been no formal review or consultations with stakeholders, Luraschi says, so it’s still unclear whether the FAO will address the raised concerns in the new reports.

The Launch of a Dedicated Food Transformation Coalition

Despite the slow movement elsewhere, one coalition has made progress. The Alliance of Champions for Food Systems Transformation (ACF) comprising Norway, Brazil, Sierra Leone, Rwanda and Cambodia, was born at last year’s COP to drive change in their country’s prospective food systems. The Alliance is “incredibly powerful [and] one of the best things that happened at COP28,” Davey says.

Supported in part by the Bezos Earth Fund, The Alliance acts across ten key priority areas to transform food systems, including food waste reduction and gender parity advancement. These sweeping focus areas are significant, says Clem Perry, director of partnerships for the Food and Land Use Coalition which acts as part of the ACF’s Secretariat, as each of these individual countries face their own unique challenges. “The production, the consumption, the trade flows, the land use challenges, the nutrition [and] health levels and challenges are very, very different in each [Alliance] country,” Perry tells Sentient.

Members of the Alliance spent this year in regular talks, both by phone and in person every three months, hashing out their biggest challenges and goals. “One of the most difficult trade-offs that we’ve been grappling with are those between improving or enhancing national feed production whilst not negatively impacting nature,” Perry says.

Sierra Leone has set an example of how to do this effectively by cracking down on their excessive rice imports and reforming their own national food system without encroaching on virgin rainforest. With a $100 million investment from the African Development Bank, Sierra Leone has put the infrastructure in place to increase rice production without deforesting. “In less than a year, that felt like a really significant and massive win and is exactly the kind of thing that we’re looking to replicate with other countries,” Perry says.

The hope is that countries can rally together to act as a collective to tackle food systems, Davey says, as we don’t want developed countries to simply offshore the environmental impact of farming to others. “We live in an integrated world. The decisions that one country takes [has] a bearing on another,” he says. It remains to be seen whether this week’s conference in Azerbaijan can correct the course.

Across Pennsylvania and other northern U.S. states, climate change -- from burning oil, coal and methane gas -- is increasing the number of winter days with minimum temperatures above freezing.

The phenomenon is known as "lost winter" and a Climate Shift Index analysis of temperatures showed more than 60% of 28 snow belt states are having at least one additional week of days above freezing.

Shel Winkely, a meteorologist and weather and climate engagement specialist for Climate Central, said winter weather will not be as cold for as long as it used to be.

"Temperatures that are below freezing -- so, 32 degrees Fahrenheit, or zero degrees Celsius -- those are important days," Winkely explained. "We found out how many days climate change has taken away overnight lows that are at or below the freezing temperature."

Winkley pointed out when you look at the 30-year average of snowfall for Pennsylvania, cities like Philadelphia now have only a 9% chance of seeing a white Christmas, with Pittsburgh faring a bit better at about 31%.

Winkley emphasized the loss of cold winter days can negatively affect some regions that depend economically on winter sports for recreation and tourism income. He added lost winter days can also contribute to a smaller snowpack, meaning less spring-melt water is available for municipal systems or agricultural operations.

"On the whole, the state, when you take the average over this decade -- again, 2014 to 2023 -- climate change added about 10 days per year above 32 degrees or so above freezing," Winkley reported.

Winkley noted the report does not mean winters are going away but the warming climate is making winters shorter and less intense.

"This doesn't mean that there's not cold, or that we're losing all of the cold," Winkley stressed. "We still have cold that is to be found. It just means that we're losing those classic winters. This isn't the winters that our parents experienced or that our grandparents experienced."

Lately, the city of Dallas has been hearing from local leaders across the U.S. and as far as London, England, said Rosana Savcic, a division manager in the city's code compliance department. What has caught their attention? A city policy that took effect in 2017 requiring landlords to provide working air conditioning equipment.

More cities are looking into establishing a renter's right to cooling equipment as climate change drives record-breaking temperatures across the world. Such rules codify tenants' right to housing that can be cooled to a specific maximum indoor temperature, a number that varies from jurisdiction to jurisdiction. Tenants may still be on the hook for their energy bills, however.

Right now, cities that require landlords to provide AC systems are the exception, not the rule, says V. Kelly Turner, a heat policy researcher and associate director of the University of California, Los Angeles' Luskin Center for Innovation.

That may be changing. Montgomery County, Maryland, passed a first-in-the-region law in 2020 requiring many landlords to provide AC equipment capable of cooling units to at least 80 degrees Fahrenheit from June through September. A 2022 Chicago law requires some large residential buildings or buildings for older people to provide AC in common spaces when the outdoor heat index exceeds 80 F. A New Orleans rule went into effect this year mandating AC equipment that can cool bedrooms to at least 80 F.

In New York City's sustainability plan, the nation's largest city indicates its intention to develop a summer indoor maximum temperature policy by 2030. In July, a NYC council member introduced legislation that would require landlords to provide AC equipment in the summer. Los Angeles County officials are in the early stages of developing a similar policy.

The case for cooling

The trend toward cooling requirements is part of a broader recognition that climate change necessitates new protections and policies, experts say.

"What we're learning is we have to develop policies specific to the issue of heat," said Ashley Ward, director of Duke University's Heat Policy Innovation Hub. In addition to rental cooling standards, heat-specific policy needs include worker protections and universal cooling for schools and prisons, Ward notes.

The major challenge proponents of rental cooling standards need to overcome, Ward says, is the public perception that air conditioning is a luxury, not a necessity. That perception "is why we can justify not having air conditioning in prisons. Forty percent of our schools in the U.S. have inadequate HVAC," Ward said. But as heat records get broken again and again, and heat-related deaths escalate, proponents see policymaker attitudes shifting.

Limitations of right-to-cooling policies

While rental cooling standards may be a step toward addressing urban heat impacts on residents, these policies aren't perfect solutions, Ward said.

Even if lower-income renters have AC equipment, they might not turn it on for fear of high energy bills. That's why some experts have urged states and cities to complement rental cooling standards with utility bill assistance programs that take cooling needs into account. States typically use much more of the federal Low Income Home Energy Assistance Program to help people with heating rather than cooling bills. And while the need for support is growing, the pot of available LIHEAP funding shrank from $6.1 billion in fiscal year 2023 to $4.1 billion in fiscal year 2024, according to a June report from the National Energy Assistance Directors Association and Center for Energy Poverty and Climate.

Cities need to start monitoring low-income households' ability to pay for cooling, Turner said in an email. That data could build a case for better supporting cooling through subsidy programs like LIHEAP.

Utilities can also help make cooling more affordable, explained Gregory Pierce, research and co-executive director of UCLA's Luskin Center and an associate professor of urban planning. State public utilities commissions can play a big role in imposing or encouraging utility-run energy affordability programs, but cities can pitch in on the effort, too, such as by collaborating with utilities on programs that make baseline amounts of energy more affordable for people, Turner said.

Tiered payment programs, for example, charge those who use a lot of electricity a higher rate than those who use less. Hotter weather, however, might mean those tiers need to be adjusted, so that the most affordable tier accounts for the amount of energy needed to cool the typical home, Pierce said.

"Not a lot of utilities have, I think, adjusted those tiers accordingly yet to account for AC, much less electrification," he said.

Any equity-oriented program must involve listening to community members about their specific struggles, Turner added. "There may be solutions we don't even know to think about because we need to hear from those that would be facing those tough choices," such as between turning on the AC and putting food on the table, she said.

Rental cooling standards also present other challenges. Cash-strapped landlords may struggle to undertake complex, expensive retrofits. Waste heat that AC equipment generates increases the urban heat island effect, and adding cooling equipment to buildings can drive up greenhouse gas emissions - although heat pumps allow building owners to simultaneously offer cooling and potentially replace fossil fuel-powered HVAC equipment.

How low should cities go?

Then there's the question of what cities should set as the maximum temperature in rental housing. Dallas' rule requires AC equipment that can keep rooms at least 15 degrees cooler than the outdoor temperature, with a maximum temperature threshold of 85 F. That means that even if it's 105 degrees outside, rental housing must be equipped to stay at 85 F or cooler.

Ward thinks cities should set the maximum temperature lower. She cites 73 F as the threshold for a good night's sleep and recovery. She recommends cities set a maximum temperature around 76 F, since fans can help bring the temperature down another couple of degrees.

However, over-debating the exact maximum temperature can stifle productive policymaking, Turner warned. She said she'd rather set the maximum temperature at 80 F and start a conversation about what it will take to implement the policy, including developing a complaint-reporting process and finding funding.

"To some degree, the question isn't, 'Can we get exactly [the right] temperature?' The question is, 'Can we get something on the books to at least give people a fighting chance of having a safe thermal environment?'" she said. "Once we do that, we can start to tinker."

Three environmental nonprofits filed suit Wednesday against the California Air Resources Board to oppose the expansion of a program allowing oil and gas companies to offset their pollution by buying credits from huge farms producing natural gas from animal waste.

Last month, the state amended the low carbon fuel standard to expand credits favoring biogas, arguing it removes methane from the waste stream and creates renewable power.

Tyler Lobdell, staff attorney for the nonprofit co-plaintiff Food and Water Watch, said the program is actually a perverse incentive for factory farms to get bigger.

"The biggest operators, the biggest polluters, are the most rewarded," Lobdell pointed out. "That is the incentive structure here. Go out and be as big and as polluting as possible, and you will see the largest reward from our program."

The low carbon fuel standard is intended to reduce carbon pollution by incentivizing the transition to clean cars. The lawsuit argued the credit program prioritizes pollution-heavy practices over sustainable solutions.

Lobdell noted manure only produces methane when large quantities are liquefied at concentrated animal feeding operations. He suggested the state require factory farms to manage their manure in ways which do not rely on anaerobic environments emitting methane.

"The real solution to addressing pollution is to reduce the pollution, not to monetize it and lock it in for generations," Lobdell contended. "We should be requiring these facilities to more sustainably manage their waste. That would have climate benefits, that would also have benefits to local air quality and to local water quality."

The lawsuit asks the court to require the California Air Resources Board to disclose, analyze and mitigate the environmental impact caused by the change to the low-carbon fuel standard. The other two plaintiffs include the nonprofits Defensores del Valle Central para el Aire y Agua Limpio, and the Animal Legal Defense Fund.
