After a tense year, the steady defrost in the US-China relationship and the expected face-to-face meeting of President Joe Biden and President Xi Jinping next week in San Francisco offers tantalising hope on climate action.
As President Biden said at this year’s United Nations General Assembly, progress on some issues hinges on their common efforts and “nowhere is that more critical than the accelerating climate crisis.”
Much ink has been spilled debating whether the US and China should cooperate or compete on addressing climate change.
These debates obscure a more important question: if revived, what could US-China cooperation on climate actually achieve?
As it turns out — a lot.
On one hand, as all countries work to implement their emissions reduction targets under the Paris Agreement, global climate progress no longer hinges so heavily on US-China cooperation.
But a high-level US-China agreement could provide the much-needed “course correction” to keep world temperatures on track to remain below 1.5C.
And it could also set the stage for a successful outcome at the Cop28, the UN’s largest annual international climate conference taking place the first two weeks of December in Dubai.
Based on what both countries are already prioritising, there is room for significant partnership when it comes to keeping domestic emissions reductions on track, raising ambition in multilateral negotiations, and accelerating climate action in developing countries.
Methane controls
Leaders from both countries have an opportunity to show that climate cooperation between the world’s two largest emitters shouldn’t just mean searching for the lowest common denominator.
To start, China’s recent delivery on its 2021 pledge, made alongside the US, to develop a plan to control methane has helped to restore trust.
Integrating non-CO2 gases into China’s climate targets would further assuage concerns that methane leakage from coal mines and other sectors could undermine action elsewhere.
Likewise, a commitment to limit emissions from burning coal could provide assurance that new coal plants won’t compromise climate targets.
In these areas, the US could lend monitoring and mitigation expertise, including from the development of its updated Methane Emissions Reduction Action Plan this year.
Hedging against a Republican administration
From China’s view, the potential for a Republican administration threatens the stability of US action and engagement.
To hedge against this, leaders on both sides could jointly endorse subnational and non-governmental cooperation.
This could pave the way for more partnerships that embed climate cooperation at multiple levels and across sectors, building on California’s recent agreement with a slew of Chinese provinces.
World Bank to initially host loss and damage fund under draft deal
US climate envoy John Kerry and his Chinese counterpart Xie Zhenhua are slated to co-host a local climate action summit during Cop28.
This could provide further opportunities to showcase and institutionalise multi-level cooperation on a global stage.
Unlocking higher global ambition
Finally, US-China cooperation could tackle thorny issues in the UN climate negotiations and unlock greater ambition.
Early, explicit communication of US-China consensus on the structure and ambition of NDC climate plans due in 2025 could lay the foundation for global consensus and position both countries as credible actors.
So too could joint communication of expectations for the new post-2025 goal on climate finance, known as the NCQG.
Doing so before Cop28 could inject important momentum ahead of a major milestone when countries will assess progress and gaps towards global climate goals – much like back in 2015, when the two countries helped lay the groundwork for the Paris Agreement by announcing their climate targets early, and together.
US raising climate finance
Perhaps US climate finance ambition could be the necessary show of goodwill to move talks forward.
This ambition was demonstrated by recent attempts to secure additional funding from Congress, supporting international financial reform at the annual meetings of the International Monetary Fund and the World Bank in early October, and an unspecified commitment to the Green Climate Fund.
For its part, China has expressed willingness to work with the US on green projects in developing countries.
Cooperation could address gaps by combining both countries’ respective strengths, such as China’s nimble construction capacity and US experience engaging with local stakeholders.
While joint projects may face hurdles, even conducting regular exchanges about shared challenges could improve investment outcomes for all sides – including, crucially, recipient countries – and create a multiplier effect.
None of this will be easy, but it is in both countries’ interests. Institutionalizing climate cooperation could weave a safety net for the US and China in light of other tensions.
New joint action could lend credence to their claims of being cooperative international players on climate – not to mention enabling substantive progress.

UN General Assembly backs “climate obligations” set by world’s top court
The UN General Assembly on Wednesday adopted a “historic” resolution calling on countries to comply with their climate obligations, as outlined in a landmark advisory opinion issued last year by the International Court of Justice (ICJ).
Last July, in the opinion first requested by the Pacific island state of Vanuatu, the world’s top court ruled that harming the climate by increasing fossil fuel production may constitute an “international wrongful act”. This could result in affected countries claiming compensation from those responsible, the court said.
To follow up on the ICJ ruling, a dozen nations led by Vanuatu submitted a proposal to the UN’s main deliberative body to recognise the advisory opinion and identify ways of implementing it.
Several large oil-producing nations mounted a late push to weaken the text by introducing last-minute amendments, but the General Assembly rejected those and adopted the resolution with 141 countries in favour at a plenary session in New York.
The resolution urges countries to implement measures to cut carbon emissions, including by tripling renewable energy capacity, “transitioning away from fossil fuels in energy systems”, and phasing out “inefficient” fossil fuel subsidies.
It also requests the UN Secretary-General to draft a report “containing ways to advance compliance with all obligations in relation to the court’s findings” by next year’s UN General Assembly in September 2027.

Pacific islands celebrate “historic” resolution
The group of Pacific island nations, which led the diplomatic push for the resolution, as well as Latin American nations and the European Union, celebrated its adoption as a “historic” moment, while some countries noted the persistence of diverging views.
Belize’s UN representative Janine Coye-Felson said in a statement on behalf of the Alliance of Small Island States (AOSIS) that the General Assembly resolution, as well as the ICJ advisory opinion, are important because “climate change is not governed only” by the Paris Agreement, but that “climate justice requires the application of the full breath of international law”.
“When future generations look back at this moment, they will ask whether we rose to meet the defining crisis of our time with the full force of international law. Today, this General Assembly answers: yes,” she told the plenary.
The EU said in a statement during the session that, with the adoption of the resolution, countries are moving beyond “simply recognising” the ICJ’s work and instead “actively upholding the legal integrity” of the multilateral system by seeking to implement the court’s recommendations.
Yet the bloc also warned the process that follows must not “seek to establish new mechanisms or engage in any determination of state responsibility”, referring in particular to the upcoming report by the Secretary-General. Earlier drafts of the resolution contained proposals to establish a register of climate-driven loss and damage and a dedicated compensation mechanism, but these were removed during negotiations on the text.
France’s ambassador to the UN, Jérôme Bonnafont, highlighted the resolution’s provision to reduce dependence on fossil fuels, and said “science clearly establishes their role in climate change”. The recent increase in oil and gas prices, which have soared because of the war in Iran, “underscores the cost vulnerability of this dependence”, he added.
Push-back by oil-producing nations
Some oil-producing countries – among them the US, Saudi Arabia and Russia – were critical of the new resolution, arguing that it creates “quasi-binding” obligations from an advisory opinion that should be non-binding, and rejected the request for a report from the Secretary-General.
“This is a direct duplication of work that is being done at the [UN climate convention],” said Russia’s delegate. “Creating a parallel process will waste resources, will undermine the fragile consensus at the conference of the parties and will lead to the fragmentation of the climate regime.”
In an effort to weaken the resolution, a group of seven oil-producing Middle Eastern states – including Saudi Arabia, Kuwait and Iran – tabled four last-minute amendments proposing to delete certain paragraphs and softening the language on the obligations of states.

In response, Pacific island nations said these amendments sought to “reopen provisions that were [the] subject of extensive negotiation”, while the EU added that they were “difficult to reconcile with the spirit of cooperation”. They were all rejected in a series of votes.
The US, for its part, described the resolution as “highly problematic” and denied the obligation of preventing climate harm beyond its borders, as well as the assertion that climate change is an “unprecedented civilizational challenge”. The country urged others to vote against the resolution.
India, which abstained, said the text failed to address the need for climate finance flows from developed to developing countries, which is “a serious omission”. The Indian delegate pointed to the absence of the term “climate finance” in the text, which “deserves more attention in a resolution that deals with the obligations of states”.
“Turning point in accountability”, activists say
WWF’s climate chief and former COP president Manuel Pulgar-Vidal said the General Assembly’s vote was a step forward that “raises the pressure on all states to act in line with their obligations”.
Rebecca Brown, CEO of the Center for International Environmental Law (CIEL), said the UN resolution shows that “multilateralism works” and with it, countries “carry the ICJ’s historic ruling forward as a roadmap for climate action and accountability”.
“By acting together, we can prevent further climate harm, in line with science and the law, by speeding up a just and equitable transition away from fossil fuels, protecting climate-vulnerable communities, and advancing climate justice,” she added in a statement.
Vishal Prasad, director of Pacific Islands Students Fighting Climate Change – a group of young people who first made the push for an advisory opinion from the ICJ – said “the world has not only reaffirmed that ruling, but committed to making it a reality”.
“This must be a turning point in accountability for damaging the climate. Communities on the frontlines, like in the Pacific, have been waiting far too long and continue to pay too high a price for the actions of others,” he said. “The journey of this idea from classrooms in the Pacific to The Hague and the United Nations gives us continued hope that when people organise, the world can be moved to act.”

REPORT: The Hidden Risks of Plastic Pouches for Baby Food
It’s been less than 20 years since baby food in plastic pouches first appeared on supermarket shelves. Since then, these convenient and popular “squeeze-and-suck” products have become the dominant packaging for baby food, transforming the way that millions of babies are fed around the world. But emerging evidence raises concerns that big food brands are feeding our children plastic pollution with unknown consequences, by selling baby food in flexible plastic packaging.
Testing commissioned by Greenpeace International in 2025 found plastic particles in the baby food products of two global consumer goods companies – Danone and Nestlé. The study suggests a link between the type of plastic the pouches are lined with – polyethylene – and some of the microplastics found. Tests also suggest a range of plastic-associated chemicals in the packaging and food of both products.
Sign the petition for a strong Global Plastics Treaty
Governments around the world are now negotiating a Global Plastics Treaty – an agreement that could solve the planetary crisis brought by runaway plastic production. Let’s end the age of plastic – sign the petition for a strong Global Plastics Treaty now.
