Ten years after the adoption of the Paris Agreement, as geopolitical tensions slow climate action, leading experts have urged ambitious countries to forge new coalitions that can drive forward efforts to limit global warming without waiting for consensus.
As the implementation of the landmark Paris accord enters a “more difficult phase”, French economist Laurence Tubiana, one of the pact’s key architects, said some countries could go ahead “with more speed and more ambition” than others.
“[The Paris Agreement] is not a Bible – it has to evolve with time,” she said. Tubiana, a former diplomat, added that the framework needs to grapple with a “much more fragmented” landscape as countries are sharply divided over the pace of the transition away from fossil fuels.
Why the Paris Agreement worked – and what it needs to do to survive
At COP30, more than 80 countries wanted a global roadmap for phasing down coal, oil and gas to be formally included in the main political outcome of the Belém summit. But strong opposition from most fossil-fuel producing nations pushed such a plan out of the final Global Mutirao decision which had to be agreed by consensus.
Instead, the Brazilian presidency promised to create voluntary roadmaps on tackling fossil fuels and deforestation outside of the UN climate process over the next year.
Move faster than global consensus
Tubiana suggested that the “next wave” of climate action could be unleashed through enforcing Article 6.1 of the Paris Agreement, which recognises that some countries “choose to pursue voluntary cooperation” in implementing their national climate plans (NDCs) “to allow for higher ambition”.
That, she added, could provide “the hook” to link initiatives led by external alliances to the official framework guided by the Paris Agreement, and make them more effective and accountable.
Echoing Tubiana’s words, Rachel Kyte, the UK’s special representative for climate, argued for building “ever more interesting coalitions within countries and across countries” among those that “continue to be inspired by Paris”.
So-called coalitions of the willing have been useful before “for some countries to move further, faster when the global consensus was not there”, she added.
Bernice Lee, a distinguished fellow at Chatham House, said countries that have already invested political and economic capital in implementing the Paris Agreement – such as China – have “skin in the game” in a way that sets them apart from those that have yet to do so. It’s a “coalition of the doing rather than just the willingness”, she added.
Climate action slows in recent years
As the United States, led by climate change–denying President Donald Trump, prepares to formally exit the Paris Agreement in January, nations in Belém “strongly” reaffirmed their unity and commitment to the accord’s goals. That came as UN Secretary-General António Guterres conceded for the first time that global temperatures will rise, at least temporarily, above the 1.5C threshold set in the Paris deal.
But even if the most ambitious target is missed, the projected global temperature increase by the end of the century has fallen by at least 1C in the decade since the landmark agreement was struck.
“That means Paris has already reduced future risks for people and ecosystems: fewer extreme heat events, lower sea-level rise, and less pressure on vulnerable communities than in a 3–4C world,” Bill Hare, CEO of Climate Analytics, said in a statement.
But he warned that climate action “has slowed in the last four years”. Now, he emphasised, “our future depends on the political will to move forward fast enough to finish the job”.
Need for “pragmatic” partnerships
Kyte advised developed countries “still in the mix”, like the UK and European Union member states, to find a different way to forge partnerships with more humility. “What we saw in Belém is that a decade of over-promising and under-delivering in many dimensions has grown old,” she said, singling out the provision of money by wealthy governments to help vulnerable countries cope with escalating climate impacts.
At COP30, a demand from the world’s poorest nations to triple adaptation finance given by rich countries was agreed, but only by a deadline of 2035 rather than 2030, and within the strict contours of the $300-billion-a-year UN climate finance goal, which covers all kinds of public funding including loans and private finance mobilised by governments.
Comment: Why the Paris Agreement worked – and what it needs to do to survive
In tackling thorny issues such as transitioning away from fossil fuels, as agreed at COP28 in Dubai, Kyte said that, while some countries are actively trying to “weaponise” this tension, others are “just fearful of a world where there is going to be some kind of diktat on how to manage their transitions”.
Once work gets underway on the roadmaps for phasing down fossil fuels and halting deforestation, “I hope we can recapture the spirit of Paris, which was about pragmatic partnership in pursuit of things which are really difficult,” Kyte added.

COP17: Key outcomes agreed at the UN biodiversity conference in Yerevan
Countries have completed the first “global review” of their progress towards reversing nature loss by 2030 at the COP17 biodiversity talks in Yerevan, Armenia.
The review “notes with deep concern” that, unless action is “rapidly accelerated”, the goal to reverse nature loss and meet a set of 23 targets by 2030 “will not be achieved”.
It “urges” countries to accelerate action, including by “increased ambition in addressing the gaps”.
Much of the discussions in Yerevan focused on how to raise the necessary funds to help developing countries protect nature.
Some major economies pushed to expand the range of nations that are expected to provide finance, with countries agreeing at the end of the two weeks of talks that non-donors that want to contribute can “signal interest” before COP18.
This came after developed countries failed to meet a target to significantly ramp up nature finance over the last few years.
It also came as a landmark fund agreed at COP16 in Colombia to pay communities for the genetic resources derived from nature stands nearly empty two years on.
The Yerevan talks marked the halfway point of the “Kunming-Montreal Global Biodiversity Framework” (GBF), the “Paris Agreement for nature” first made in 2022 and due to be achieved by 2030.
During the nearly 12-hour-long final plenary, countries voted for Quito, Ecuador, to host the COP18 nature talks, which will be held in 2028.
Countries managed to sign off on all the major negotiation texts, marking a stark contrast to COP16, which ran so far over time that the Colombian presidency lost “quorum”, forcing talks to resume in Rome months later.
Below, Carbon Brief has detailed analysis of all of the key outcomes from COP17.
Formal negotiations
Finance
Finance, predictably, was at the heart of the discord and deadlock at the Yerevan talks.
At COP17, discussions on finance had to achieve several outcomes.
The first part – to take stock of biodiversity finance mobilised so far to meet the nature deal’s goals – fell under the global review.
As the global report noted, developed countries failed to meet their commitments to raise “at least $20bn a year by 2025” for nature. Delegates pointed to falling aid levels and a sharp 27% decline in environmental funding for the 2026-30 period.
The second part was to agree on how to mobilise resources for the next four years, to meet the GBF’s goals and targets.
Calls to “broaden the contributor base” of who pays to protect nature – and whether that should include emerging economies – became the most fraught element of the talks.
Eventually, countries agreed on what Switzerland described as a “super, mega-delicate” text. It hinged on major “political compromises”, with “no major winner or loser”, according to Kenya.
Per the decision, countries that want to be included on a list of developed country donors can “signal interest” through bilateral, confidential consultations before COP18 and every alternate COP after.
Finally, countries also agreed on criteria to shape and resource a new, permanent financial mechanism to protect nature after 2030.
However, this did not immediately take the form of a new fund under the COP that biodiverse countries have demanded since 2022, deferring the mechanism’s institutional structure to COP18.
Resource mobilisation discussions at the GBF’s halfway mark were supposed to agree on how to close the “biodiversity finance gap” and to “increase resources from all sources” to “at least” $200bn per year by 2030, as set out in target 19 of the GBF.
The talks were largely dominated by a push, led by the JUSCANZ bloc of developed countries, to “broaden the contributor base”. This could see emerging economies, such as Qatar, China, Saudi Arabia and India, being added to the list of countries that pay to protect nature.

Article 20 of the UN Convention on Biological Diversity (CBD) states that developed countries “shall provide new and additional financial resources” to developing countries to meet the costs of implementing measures to protect nature.

The text states that other countries – including emerging economies – may “voluntarily assume” these obligations to pay. However, it adds that this list of developed countries “shall” be reviewed periodically and amended “if necessary”.
The list was last amended in 2006.
(See this “jargon buster” which explains the specific meaning and legal weight of various terms and verbs used in UN formal documents.)
Discussions around this fraught subject had reached a dead end at intersessional talks this year, but resurfaced in Yerevan.
The first “non-paper” had four different options for expanding the contributor base. These ranged from using the World Bank’s country income groups “as a proxy” to identify high-income countries, to commissioning a study on the impacts of being included on the list.
By 21 October, the number of options swelled to eight, including two from Saudi Arabia and one from Peru.
Some countries “expressed concern” that certain options were based on a CBD secretariat study on “what constitutes a developed country”, Earth Negotiations Bulletin reported.
By the end of the first week, it was clear that the finance deadlock would have to go into informal ministerial consultations for any consensus to emerge.
At a press conference on 28 October, Christopher O’Sullivan, Ireland’s nature minister and representing the EU delegation, told Carbon Brief:
“Our position isn’t that we want to pull back in terms of contributing…but it’s been 20 years since that list was added to, times have changed and there are new realities. We just simply want those new realities reflected. I don’t fully understand why there’s so much opposition to that.”
The EU chose not to comment on which countries it would like to see on that list.
Lim Li Ching from the Third World Network, meanwhile, called the push for others to “assume the obligations” of developed countries “sheer hypocrisy”, adding that any country could make a voluntary contribution. She told Carbon Brief:
“At a forum like the CBD, this linking of income status with finance does not take into account where historical and current responsibilities lie. If you want to generate more funding for biodiversity, let’s look at sovereign debt burdens and rules, which are inequitable for developing countries. But if you can fund wars, and provide resources for your defence industry, then you know where the priorities are.”
On 29 October – at a plenary meant to adopt final texts for the most contentious subjects – Norway’s Gaute Hanssen announced that resource-mobilisation discussions would go into a smaller “friends of the chair” meeting.
Facilitated by Carolina Caceres from Canada and Imèn Meliane from Tunisia, the meeting would discuss the most contentious elements of a draft decision that had swelled to 112 brackets, denoting areas of disagreement on specific details in the text.
While the meeting was open to all, countries that were called to be present included Brazil, Canada, Chile, China, the EU, Fiji, Norway, Russia, Switzerland, Saudi Arabia, South Africa and the UK.
At the same time, a “non-paper” text by finance and environment ministers laid out countries’ red lines and compromises.

At the end of COP17, countries welcomed a final compromise text, with Kenya thanking the “strong women” co-chairs who strove to strike a “delicate” balance.
China, Saudi Arabia, Switzerland and Fiji cautioned against any further interventions, with Brazil warning: “If we open this text, we will never close it again.”
While the final decision “recognises” that “contributions from more parties would improve the mobilisation” of biodiversity finance, it steered away from issuing criteria to expand the list of donor countries.
The text makes it clear that no additions to the list would be made without inviting and confidentially consulting with interested countries, to secure their explicit consent.
Instead, the CBD secretariat “invites” countries keen to be on the list and “assume the obligations” of developed countries to “signal interest” before COP18 and at every alternate COP thereafter.
At the same time, developing countries can contribute to meeting the GBF and biodiversity convention’s goals on a “voluntary basis”, with contributions not implying inclusion on the list.
A negotiator for China told Carbon Brief at the closing plenary:
“We welcome this balanced document. It was a very long discussion that has gone [on] since [2022 nature talks in] Nairobi. But actually this time, there were a lot of sensitive issues, [there were] a lot of critical things we didn’t open in the contact groups; it mainly went to the high-level discussion.”
The decision also establishes a financial mechanism for nature funding after 2030 under the governance of the COP, a key ask from developing countries.
However, it defers decisions on what form this mechanism would take – whether this would be a new fund or based on existing arrangements – until COP18.
Oscar Soria at the Common Initiative told Carbon Brief that the decision on the financial mechanism leaves things “very open”, with “no movement” towards a new fund or money and no upgrades to existing funding arrangements.
The text acknowledges the links between debt and biodiversity eight times, mentioning how debt-related instruments can be included in biodiversity plans, but does not go further.
“It is almost as if the debt studies they called for at COP16 didn’t happen,” said Soria, who had earlier flagged serious methodological issues with the first-ever
