Negotiators from world wide 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 top of the last decade. However that’s an enormous ”if,” particularly since nations stay reluctant to sort out the largest supply of methane emissions.
Methane is a mighty greenhouse fuel, roughly 30 occasions extra highly effective than carbon dioxide with regards to trapping warmth within the ambiance. 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 chopping humanity’s methane output is without doubt one of the quickest methods to cut back the planet’s charge of warming.
It additionally has worth as a gasoline, so there’s a monetary incentive to seize methane and burn it somewhat than let it escape. As well as, lots of methane air pollution tends to come back from distinct sources like fuel wells and landfills, so concentrating on these amenities 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 thus far have already signed onto the World Methane Pledge. It commits signatories to chopping methane emissions from human sources by 30 % from 2020 ranges by the top of the last decade, which, if achieved, 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 scale back methane.
The USA is the third-largest methane-emitting nation after China and Russia. The brand new US methane laws on the oil and fuel business, 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 tools upgrades and common inspections of air pollution management techniques.
The regulation even received reward from an oil firm: “We respect the collaborative manner EPA, NGOs and business labored collectively on this rulemaking,” BP America president Orlando Alvarez mentioned in a press release. “Within the spirit of COP28, enter from a broad vary of stakeholders makes for extra sturdy and efficient insurance policies.”
This yr at COP, a variety of companies have additionally promised to chop their methane output. Below the Oil and Fuel Decarbonization Constitution, 50 corporations 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 observe the place oil wells burn off amassed methane somewhat than capturing it on account of laws, 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 corporations keep away from flaring, however main oil and fuel corporations like Chevron and Exxon Mobil declined to chip in for now.
Few of the introduced actions, nonetheless, embrace the biggest driver of methane air pollution: the meals we eat.
From tilling soil to planting crops, to fertilizer, livestock, manure, harvesting, transport, and waste, meals techniques produce 34 % of general greenhouse fuel 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 world wide collectively burp up 231 billion kilos of this greenhouse fuel.

There have been some small efforts at COP28 to handle the local weather affect 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 power necessities than a extra animal-heavy menu. Greater than 100 nations agreed to search out methods to cut back emissions from meals manufacturing. The US and the UAE introduced that they pooled $17 billion to advance extra climate-friendly farming techniques world wide. 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 mentioned they’ll 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 eat essentially the most animal merchandise, as Vox’s Kenny Torrella defined:
The disinterest from Western governments in shifting diets isn’t stunning — meat stays the third rail of local weather politics. It tastes good, it’s grow to be a mainstay of Western diets, and it’s grow to be linked to beliefs like prosperity and masculinity. Taking it off the menu to assist save the planet isn’t politically in style, so even eco-minded politicians, environmental activists, and local weather reporters largely keep away from the problem.
Based on paperwork obtained by DeSmog and the Guardian, some lobbyists at COP28 are even making the case that extra meat and dairy are useful to the atmosphere. The Guardian additionally reported that some former officers on the United Nations Meals and Agriculture Group (FAO) mentioned 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. Based on the FAO, methane emissions from livestock must fall 25 % by 2030 in comparison with 2020 with a purpose to keep heading in the right direction for the Paris local weather settlement aim to restrict international warming this century to lower than 1.5°C or 2.7°F. Total emissions of heat-trapping gasses are nonetheless slated to extend, placing these objectives nearly out of attain.
Even with the brand new spherical of commitments at COP28, the world will doubtless blow previous the 1.5°C aim, based on the Worldwide Vitality Company, and it stays to be seen whether or not even these tepid guarantees will probably be fulfilled.
