Negotiators from all over the world assembly on the COP28 local weather convention within the United Arab Emirates (UAE) final week agreed to place more cash behind pledges to chop methane air pollution. If met, these commitments would avert a big quantity of warming earlier than the tip of the last decade. However that’s an enormous ”if,” particularly since nations stay reluctant to deal with the largest supply of methane emissions.
Methane is a mighty greenhouse gasoline, roughly 30 occasions extra highly effective than carbon dioxide on the subject of trapping warmth within the environment. About 60 % of worldwide methane emissions come from human exercise, accounting for 1 / 4 of all warming. However in contrast to carbon dioxide, it doesn’t linger that lengthy within the sky, so slicing humanity’s methane output is without doubt one of the quickest methods to scale back the planet’s charge of warming.
It additionally has worth as a gas, so there’s a monetary incentive to seize methane and burn it moderately than let it escape. As well as, lots of methane air pollution tends to come back from distinct sources like gasoline wells and landfills, so focusing on these services for cuts can have an outsize impact.
This all makes methane a ripe, juicy goal for folks hoping to curb local weather change — yielding higher reductions in warming and at decrease prices than simply limiting carbon dioxide.
Greater than 150 nations up to now have already signed onto the International Methane Pledge. It commits signatories to slicing methane emissions from human sources by 30 % from 2020 ranges by the tip of the last decade, which, if completed, has the potential to avert 0.2 levels Celsius of warming by 2050 (0.36 levels Fahrenheit).
At COP28, a number of nations — together with the US, Canada, Brazil, and Egypt — introduced how they plan to fulfill their targets, and nations introduced greater than $1 billion in new grant funding to assist cut back methane.
The US is the third-largest methane-emitting nation after China and Russia. The brand new US methane rules on the oil and gasoline trade, which the Environmental Safety Company introduced as a closing rule on the convention, would avert 58 million tons of methane air pollution between 2024 and 2038. The regulation additionally requires gear upgrades and common inspections of air pollution management programs.
The regulation even gained reward from an oil firm: “We admire the collaborative means EPA, NGOs and trade labored collectively on this rulemaking,” BP America president Orlando Alvarez stated in an announcement. “Within the spirit of COP28, enter from a broad vary of stakeholders makes for extra sturdy and efficient insurance policies.”
This yr at COP, various companies have additionally promised to chop their methane output. Beneath the Oil and Gasoline Decarbonization Constitution, 50 firms accounting for 40 % of worldwide oil manufacturing dedicated to eliminating their methane emissions by 2050. Additionally they dedicated to ending flaring by 2030. Flaring is a apply the place oil wells burn off gathered methane moderately than capturing it on account of rules, for security, or as a result of it’s less expensive. To facilitate this, the World Financial institution introduced the creation of a $250 million belief fund to assist firms keep away from flaring, however main oil and gasoline firms like Chevron and Exxon Mobil declined to chip in for now.
Few of the introduced actions, nonetheless, embody the most important driver of methane air pollution: the meals we eat.
From tilling soil to planting crops, to fertilizer, livestock, manure, harvesting, transport, and waste, meals programs produce 34 % of total greenhouse gasoline emissions. Agriculture is the single-largest anthropogenic, or human-driven, supply of methane, and most of that’s from our urge for food for meat. Animals raised for meals account for 32 % of human-driven methane.
Only one cow can produce wherever from 154 to 264 kilos of methane yearly, so the 1.5 billion cattle raised for beef all over the world collectively burp up 231 billion kilos of this greenhouse gasoline.

There have been some small efforts at COP28 to handle the local weather impression of meals, and the assembly has devoted extra time to agriculture than previous conferences. Greater than two-thirds of the menu for the convention was plant-based, which comes with far smaller land, water, and vitality necessities than a extra animal-heavy menu. Greater than 100 nations agreed to seek out methods to scale back emissions from meals manufacturing. The US and the UAE introduced that they pooled $17 billion to advance extra climate-friendly farming techniques all over the world. There have been additionally a pair new bulletins to deal particularly with methane. Canada launched incentives for Canadian ranchers to chop methane emissions from their cattle farms. And a number of other of the world’s largest dairy producers stated they are going to start reporting their methane emissions subsequent yr and draft plans to ratchet them down.
However there’s been little urge for food for decreasing demand for meat and dairy, significantly among the many rich nations that devour probably the most animal merchandise, as Vox’s Kenny Torrella defined:
The disinterest from Western governments in shifting diets isn’t shocking — meat stays the third rail of local weather politics. It tastes good, it’s develop into a mainstay of Western diets, and it’s develop into linked to beliefs like prosperity and masculinity. Taking it off the menu to assist save the planet isn’t politically standard, so even eco-minded politicians, environmental activists, and local weather reporters largely keep away from the problem.
In response to paperwork obtained by DeSmog and the Guardian, some lobbyists at COP28 are even making the case that extra meat and dairy are helpful to the surroundings. The Guardian additionally reported that some former officers on the United Nations Meals and Agriculture Group (FAO) stated their work exhibiting the damaging methane results from livestock was sidelined and censored.
The reluctance to even acknowledge the local weather impacts from elevating animals for meals is troubling on the tail finish of the hottest yr ever recorded. In response to the FAO, methane emissions from livestock must fall 25 % by 2030 in comparison with 2020 to be able to keep on target for the Paris local weather settlement purpose to restrict international warming this century to lower than 1.5°C or 2.7°F. General emissions of heat-trapping gasses are nonetheless slated to extend, placing these targets nearly out of attain.
Even with the brand new spherical of commitments at COP28, the world will possible blow previous the 1.5°C purpose, in line with the Worldwide Vitality Company, and it stays to be seen whether or not even these tepid guarantees will likely be fulfilled.
