With voluntary commitments to cut methane pollution floundering, the prime minister of Barbados urged fellow leaders at the United Nations last month to draw up a “legally binding global agreement” to reduce emissions of the particularly potent greenhouse gas.
Mia Mottley told the UN Secretary-General’s Climate Summit in New York that voluntary efforts like the UAE-led Oil and Gas Decarbonisation Charter – signed by over 50 oil and gas companies – were “not enough” to rein in methane. She said governments should urgently discuss a “no more than two-or-three page agreement on the reduction of methane as a matter of legally binding obligations”.
The Barbadian leader – who has a global reputation for proposing new ideas on climate action and finance – said governments “do not need to reinvent the wheel”. She suggested replicating the 1987 Montreal Protocol that has phased out the production and use of CFC and other gases found in fridges and air conditioners that were responsible for opening a hole in the Earth’s ozone layer.
That protocol put in place legally binding reduction targets for these chemicals, many of which are also greenhouse gases, incentivising government policies to make companies redesign their appliances.
Emissions of ozone-depleting substances have since dropped by almost 100%, and the ozone layer is closing, with Mottley calling it “the most successful climate agreement in history”.
Why focus on methane?
Methane is a short-lived greenhouse gas that is more than 80 times more potent than carbon dioxide (CO2). Experts say cutting methane emissions is a “low-hanging fruit” for tackling global warming, as it would make a big difference with relatively small actions.
Methane emissions come mainly from the agriculture sector (40%), the oil and gas industry (35%) and waste (20%).
Since COP26 in Glasgow, 111 countries have signed up to the Global Methane Pledge – which aims to cut methane emissions by 30% by 2030, compared to 2020 levels.
But, in its latest global tracking update in May, the International Energy Agency said methane emissions from fossil fuels remain at stubbornly high levels. Commitments like the pledge have boosted target-setting and momentum, it added, but so far “few countries or companies have formulated real implementation plans for these commitments, and even fewer have demonstrated verifiable emissions reductions”.
Russia justifies fossil gas use by citing contentious COP28 loophole
Mottley told the summit at UN headquarters that tightening regulation on methane emissions made sense for the planet, fossil fuel firms and farmers – and would help buy time in the short-term as countries roll out their national climate plans to cut greenhouse gases across the board.
Her call was backed by French President Emmanuel Macron and Tuvalu’s Prime Minister Feleti Teo, who both said in their speeches that a “binding commitment” on methane is needed. “We know that this is a reachable goal,” Macron said, adding that methane reduction would be a priority when France chairs the G7 next year.
A more difficult challenge than ozone?
But replicating the Montreal Protocol for methane will be challenging. The vast majority of ozone-depleting gases come from a relatively small number of appliances and so could be reduced relatively easily. On the other hand, methane escapes into the atmosphere from a wide variety of sources including belching cows, rice paddies, landfills, leaking gas pipelines, coal mines and oil production facilities.
While some emissions can be prevented cheaply or even profitably – particularly in oil and gas production – others, like those from cows, are more expensive and politically controversial to avoid.
Durwood Zaelke, president of the Institute for Governance and Sustainable Development, has previously campaigned against ozone-depleting substances and is now pushing for methane cuts. He spoke alongside Mottley and Macron at a high-profile meeting on methane in New York in late September.
He told Climate Home News that getting a “coalition of the willing” to agree on methane targets is more likely than persuading all the world’s governments to sign up to an agreement. Countries could make their targets legally binding through their own domestic law, he said.

An international agreement is possible, he added, “but it also can start from the bottom up” if other governments – including sub-national ones like California and Punjab – adopted similar rules to the European Union’s methane regulation.
The EU requires oil and gas companies to detect and repair methane leaks and bans them from burning gas as a waste product in a process known as flaring. It is also imposing increasingly stringent methane intensity standards – opposed by the Trump administration in the US – on imported fossil fuels.
Zaelke said the next step was for Barbados to try and get the rest of the Climate Vulnerable Forum – a group of around 70 Global South countries which it now chairs – and other small island states on board with the idea.
He predicted that methane would have its “moment” at the COP30 climate summit in Brazil, as reduction of non-CO2 gases is one of the 30 objectives of the COP30 presidency’s “action agenda”.
Mottley’s proposal is expected to be discussed at the pre-COP gathering in Brasilia on October 13-14, although opposition from some countries will likely make reaching global consensus very difficult.
Citing comments by UN chief Antonio Guterres that we are on “the highway to climate hell”, Zaelke said: “We’ve got a methane emergency brake. If you pull it and turn the wheel, you can reverse course and slow warming in the near term more than any other way. I think this is becoming clear and so we’ll see the drumbeat for mandatory pick-up.”

Mottley’s “legally binding” methane pact faces barriers, but smaller steps possible
At Climate Home News, we found this year a pretty depressing one to cover, shaped as it was by Donald Trump’s attacks on climate science and action at home and abroad – and rounded off by the UN declaring global warming will break through the key 1.5C limit the world set itself in 2015.
But it wasn’t all bad. Nobody had decided to follow the US out of the Paris Agreement by the time it turned 10 this month. Anti-climate candidates in Canada and Australia, backed by Trump, lost elections convincingly. And 2025 may also have been the year carbon dioxide emissions fell for the first time.
What’s more, our reporting this year saw results in the real world. After we revealed that Chilean doctors believe pollution from copper mines in the northern hub of Calama is causing autism, campaigners sued state-owned mining company Codelco. The case is ongoing.
One of the lawyers representing the campaigners said “when [Climate Home News] revealed our silent suffering and our fight, we felt we had finally been heard and had entered the national conversation thanks to international media coverage. That was the final push to file the lawsuit.”

Below are nine of our best stories this year and, if that’s not enough, here’s nine more from 2024.
1. Solar squeeze: US tariffs threaten panel production and jobs in Thailand
In the year of trade wars, Trump extended Biden-era tariffs on solar panels from China to neighbouring countries. Nicha Wachpanich spoke to some of those workers who subsequently lost their jobs making panels at Chinese-run factories in Thailand and found that the US levies and bad behaviour by bosses had combined to crush their dreams of a better life.
2. Business-as-usual: Donors pour climate adaptation finance into big infrastructure, neglecting local needs
Trump being Trump, and axing US climate finance, is no reason to let other wealthy donor nations off the hook. We examined the latest spreadsheets for annual adaptation aid and found Japan is counting support for massive infrastructure projects in its figures, despite them having only a dubious role in helping people adapt to climate change.
Our reporter Tanbirul Miraj Ripon visited one such project – the Matarbari port in Bangladesh. He found that the port handles coal and gas imports and has destroyed locals’ homes and livelihoods. Despite this, on paper it represents $363 million in Japanese climate adaptation finance, the biggest single climate resilience project being funded by a wealthy country in 2023.
3. Ethiopia’s bold EV ambitions hit bumps in rural areas
Other nations are trying hard to go green but finding it tricky. This year, Ethiopia hosted the Africa Climate Summit, was selected as the host of COP32 and opened the continent’s biggest hydropower dam.
It plans to use some of this clean power to charge electric vehicles, after banning imports of cars with internal combustion engines (even as the European Union is softening its own 2035 ban on ICEs). While that will reduce Ethiopia’s already tiny emissions and its fossil fuel import bills, it won’t be easy in a nation where only half the population has electricity access, as Solomon Yimer and Vivian Chime reported.
4. Ending poverty and gangs: How Zambia seeks to cash in on the global drive for EVs
Other African governments are trying to cash in on their minerals, which big players like China, the US and increasingly Saudi Arabia want for green technologies and/or making equipment for wars.
Pamela Kapekele went to look at the situation in Zambia’s Copperbelt province – where you can probably guess what they produce! She found that good tax regulations and working conditions will be needed if locals are to see the benefits of surging demand for the metal.
Later in the year, an acid spill from a copper-mine tailings dam that contaminated the country’s main river showed the value of environmental regulation too. Reporting from Nigeria’s lithium and South Africa’s platinum mines also highlighted the challenges of making minerals mining and processing cleaner and fairer for communities.
5. Is the world’s big idea for greener air travel a flight of fancy?
Some sectors – like international aviation and shipping – tend to fall outside the scope of national media, and it’s a gap we’ve aimed to fill. Together with Singapore’s Straits Times, we tracked the supply chain for what the airline industry calls “Sustainable Aviation Fuel” (SAF) and found that virgin and barely used palm oil – which threatens rainforests – is being passed off as waste cooking oil and used to power planes in Europe.
Malaysia is a particular hotspot for this fraud, as government subsidies there make virgin palm oil cheap in the shops – and it can be sold for a higher price as “used” cooking oil, providing a profit motive for flipping it. Our investigation was picked up by the Financial Times, Bloomberg and the Malaysian authorities, who have since launched a crackdown on this kind of fraud.
But with verification of the materials used for SAF relying on just a handful of commercial auditors conducting mainly paper-based checks, airlines currently cannot know for sure if their green jet fuel is actually sustainable. Their advertising to passengers should – but often doesn’t – reflect this uncertainty.
6. Brazil’s environment minister suggests roadmap to end fossil fuels at COP30
Our reporting was often prescient this year. We called it correctly that the US would leave the Paris Agreement but not the UNFCCC, that Argentina would not follow America out of Paris, that Ethiopia rather than Nigeria would be chosen as COP32 host and that petrostates would try to kill a new green shipping framework at the International Maritime Organization.
We are also pretty sure we were the first – at least in English – to pick up on Brazilian Environment Minister Marina Silva’s proposal for COP30 to agree on a roadmap away from fossil fuels, which she aired back in June at London Climate Week. That proposal was pushed by President Lula at the start of COP30, dominated much of the conversation at the summit and will continue to be discussed throughout 2026.
8. PR firm working for Shell wins COP30 media contract
In the summer of 2025, our crack investigative reporter Matteo Civillini got the scoop on how the Brazilian government, via a contract tendered by the UN, was working with Edelman on international media relations for the COP30 climate summit while the global PR giant was simultaneously engaged in promoting Shell’s fossil fuel interests in Brazil.
This story was picked up by a range of other media, and amplified calls for agencies whose clients include fossil fuel firms to be excluded from the climate negotiations. Advocacy group Clean Creatives was inspired by Matteo’s reporting to launch a campaign against Edelman’s COP involvement. That culminated in an open letter from influencers and creators with a combined audience of over 24 million calling for Edelman to be dropped. The drumbeat on this theme is likely to get louder in 2026.
8. “House of cards”: Verra used junk carbon credits to fix Shell’s offsetting scandal
And talking of smoke and mirrors, just when we thought the murky web of carbon offsetting linking oil and gas major Shell to sham rice-farming projects in China couldn’t get any more convoluted, it did exactly that.
By combing through the records of carbon-credit registry Verra – the world’s biggest – Matteo confirmed that nearly a million bogus offsets from 10 disqualified methane reduction projects had been compensated for with the same number of junk credits from another four such projects that were also axed by Verra.
“It’s frankly unbelievable that Verra considers it appropriate to compensate for hot air credits with other hot air credits,” Jonathan Crook, policy lead at Carbon Market Watch, told us. “To pretend this is a satisfactory resolution is both absurd and deeply alarming.”
Verra insists the replacement credits were technically available to plug the gap left by the first batch – even though the second set, too, now need to be swapped out. Shell is keeping its distance, saying it does not manage or operate “the projects in question” despite being earlier involved in the Chinese rice-farming programmes as their “authorised representative”. Mind-boggling indeed!
9. Self-taught mechanics give second life to Jordan’s glut of spent EV batteries
In what was on balance a bad year, we brought you some hope too. A landmark advisory opinion on climate change and human rights from the International Court of Justice in The Hague was stronger than anyone imagined and may open the door to lawsuits against polluting countries and companies in 2026.
Other good news stories included analysts suggesting China’s fossil fuel use could peak this year, the UN’s loss and damage fund launching its first call for proposals, South Korea and Morocco moving to phase out coal and a boom in imports of solar panels to Africa.
Hope came too from ordinary people and their ingenuity – like the untrained Jordanians interviewed by Yamuna Matheswaran, hooking up solar panels to old Tesla batteries, lowering both their electricity bills and their carbon emissions into the bargain.
