Since Donald Trump moved into the White House for his second term as president in January 2025, you’d be forgiven for thinking the US has abandoned all action to tackle climate change and is working aggressively to undermine the efforts of other countries towards that end.
This week, at the Spring Meetings of the International Monetary Fund and World Bank in Washington DC, US Treasury Secretary Scott Bessent cast doubt on the scientific consensus around global warming and pressured the two institutions to reverse what he called their “mission creep” and “myopic focus” on climate.
But this hostile rhetoric from the Trump administration and its withdrawal from the UN climate regime – coupled with its support for fossil fuels – doesn’t tell the whole story of what’s happening in the US, according to Lou Leonard, the first dean of the School of Climate, Environment, and Society at Clark University.
At the state, city and community level, as well as in business and higher education, efforts are resolutely continuing to reduce planet-heating emissions, boost clean energy and adapt to climate shocks, Leonard, an environmental lawyer, told Climate Home News in an interview from Massachusetts.
Thanks to impetus from coalitions such as America Is All In – whose predecessor group he helped launch – the US can still make significant progress towards its 2035 goals to cut emissions, research shows. Leonard, who worked as senior vice president for climate and energy at the World Wildlife Fund for over a decade, explains how US climate action and the Paris Agreement can survive Trump’s wrecking ball.
Q: Has the effect of the Trump administration’s efforts to undermine global climate action and the UN climate process been worse than you expected?
A: A thing that is striking to me, looking at the decade of the Paris Agreement… is that over the course of that decade, the United States had a hostile sort of leadership in Washington, and the agreement has endured.
And it has endured despite the United States, not because of the United States – at least from a federal standpoint. The US was really important in the formation stage but has not been as vital to the endurance of the agreement.
Q: Is it not fair to say though that the current US abandonment of the UN climate process could reduce the impact and influence of the Paris Agreement?
A: The nature of an international cooperative framework means that the aggregate ambition is as strong as the countries that make up it, right? I’m not saying that, in the dream scenario where every country was in a really aggressively positive place that we would not get more out of the international framework. There’s no question that that’s true.
I think it’s just when we’re thinking about the singular role of one country – even the United States – there’s much more in play here than that theory of how things were going to work; the centrality of the United States to all this, especially at the Washington level. I think that turned out to be wrong – at least in the longest sweep of the progress that we’ve made.
Fossil Free Zones can be on-ramps to the clean energy transition
I think the reason why what’s happening in Washington didn’t have as great an impact as it might have in the rest of the world is because the story of what’s happening in the United States is not limited to what’s happening in Washington.
And that’s the second part – which is the things that sometimes frustrate people about the American political system – the sharing of power and the federal system, and all of those things which were intentionally built into the US system.
In these moments, that structure has helped create a reality… and then the rest of the world can see for itself that there’s all these efforts through America Is All In and in other places to bring those actors and that leadership and analysis of the impact of that effort to the rest of the world. I think that that has been an important part of the story of why the Paris Agreement has endured.


Q: What have some of the most important of those subnational efforts been in your view?
A: California’s the most obvious example, because it’s the world’s sixth largest economy and it’s certainly one of the most aggressive states moving forward on climate action. But it’s more than that: if you look at the America Is All In analysis that was released at COP30 in Belém, it shows a roadmap to maintain US trajectories, as a way to keep things from really collapsing when you have these changes in federal leadership.
There’s a parallel there to what’s happening globally – this is a distributed effort. We need all of society, all over the world, to be moving in this direction in order to reach our most ambitious goals.
And I think the fact that the US has over half of the economy, at least, really leaning in this direction really helps. And then if you just look at the energy transition in the US, we have begun to reach this tipping point where the role of the markets and the role of politics are shifting to some degree.
We really needed the policy incentives, and a lot of that [earlier] signal coming from Washington and then the states to get us to a point where renewable energy penetration was significant enough to begin to have momentum on its own, and I think we’re starting to see that. In just the last two years, over 90% of the new generation capacity in the United States has been renewables.
Q: Where do you see real momentum on US climate action continuing or gathering pace despite what Washington is up to?
A: What I really think is going to take us to another level than just relying on state governments… is the catalysing of more of a collaborative “all of society” approach here.
That’s what led me to higher education. I felt like there was an understanding and an alignment within higher education of the importance of these topics – and then the bench within higher education is filled with some of the top experts in the world on climate who were already leading as it related to climate science and talking about the problem. But if we could take that capacity and bring it into more direct relationship with businesses, municipalities and states, then that has the potential to unlock more of the impact of those actors together … that’s the reason I made the move.
The thing that drew me to [Clark] was you had a small university with really a national research capacity. And in Massachusetts, you have the only state in the country that has a chief climate officer that reports to the governor. You’ve got policy that’s been put in place related to green banks and zoning rules related to decarbonisation of buildings. And a state-based climate law that’s aligned with the Paris Agreement goals and has decarbonisation or net zero emissions by mid-century. You’ve got that policy piece in place, and then it’s how can you begin to catalyse some more of the collaboration that’s going be necessary to actually meet those goals? I think that’s really exciting.

Another place where we’re seeing these ingredients come together is Pennsylvania. Just a month ago, the state of Pennsylvania created a new programme called Prepare PA, which is both about preparing for climate impacts and reaching goals related to the energy transition and the like. And they’re putting Penn State University at the centre of trying to help them implement a plan that involves businesses and municipalities. I think you’re seeing more and more of this kind of experimentation.
… This was always going to be an all-of-society effort, and the more we can see that, and the more we can make it real – how we all have roles to play at the local level, at the state level, in the private sector, in universities, in civil society, the more we have the opportunity to avoid this sense of powerlessness [about climate change] that can lead us to nihilism.

IPCC scientists vow to press on with climate reports despite political deadlock
Scientists have vowed to keep working on the next flagship set of reports for the Intergovernmental Panel on Climate Change (IPCC), after a political row over the timeline for their release saw its latest session suspended on Friday evening without agreement.
During the weekend, government officials and scientists alike expressed disappointment over the inability to reach a compromise before some delegates from developing countries and small island states had to leave the week-long meeting in Ethiopia to catch flights home.
The disagreement – which has persisted since early 2024 – turns on whether the three key parts of the AR7 assessment should all be published before the conclusion of the UN’s next Global Stocktake of global climate action, which is due to be completed in late 2028.
The IPCC issued a statement after the close of the session, saying that “key agenda items” – the timelines for the three AR7 reports, as well as the IPCC budget – remain open and under discussion. It said the IPCC’s plenary session and its deliberations on the pending agenda “will resume at the earliest opportunity”, giving no further details of when.
IPCC Chair Jim Skea told delegates in closing remarks that recent months had been some of the most turbulent for the climate science panel and that, if there were stronger words than “profound disappointment” he would use them, according to a summary published by the Earth Negotiators Bulletin (ENB). IPCC discussions happen behind closed doors.
IPCC scientists remained committed
In an open letter, issued on Monday, a group of nearly 120 scientists – from a total of 664 AR7 authors – said they “stand committed to continue working to deliver the AR7 reports in a manner that is rigorous, timely and inclusive, in line with our mandate to be policy-relevant”.
“An assessment that arrives after the decisions it is meant to inform cannot serve its purpose,” they emphasised. “The second Global Stocktake in 2028 is such a decision point, and the world should not have to face it without the IPCCʼs latest assessment.”
Europe, small islands and the least developed countries, plus many Latin American and developed nations, want the IPCC to meet this deadline, arguing that the findings from the UN climate science body are irreplaceable in the UN climate policy-making process.
However, around a dozen developing countries plus Russia have argued that the reports should come later in order to allow for greater research input from the Global South – something that, in their view, would make the findings fairer. They also claim that a shorter timeline would put excessive pressure on experts.
The most vocal of this group at last week’s meeting were India and Saudi Arabia, according to the ENB summary and a developed country diplomat. Critics see this push for a longer timeline as an excuse to deprive government decision-makers of the latest science and ease pressure on emerging economies to raise their ambition, particularly on cutting emissions.
Commenting on last week’s meeting, France’s ambassador for climate negotiations Benoît Faraco said a broad coalition of developed and developing countries from all five continents, “united in their support for science and the timeline proposed by scientists”, had withstood pressure “from a few countries” seeking to slow down the process of adopting the IPCC reports.
He added that France would not back down and would “continue to fight tirelessly for science, protect the integrity of information, and convince our partners that without the best available scientific data, we will be less effective in tackling climate change and protecting our populations”.


Inclusivity proposal stalled
In a bid to unlock a solution for the AR7 timeline, countries discussed ways to improve the inclusivity of the IPCC’s work. One option put on the table was for the IPCC to expand its funding for delegates from developing countries to attend some or all of its sessions from one to two participants, according to the ENB summary and a delegate speaking to Climate Home News.
That would increase the costs for the IPCC to complete AR7 by up to a quarter, according to an assessment shared by the secretariat. The panel’s budget is under severe strain and its officials have warned that, without additional voluntary contributions, it risks running out of money before it can deliver on this assessment cycle.
Climate Home News understands that some of the IPCC’s traditional donors – which mainly include European countries, Japan and Australia – indicated a willingness to support funding for an additional developing country participant. But without an agreement over the budget or the timeline for the reports, that option was ultimately not adopted.
‘Disappointed and worried’
The three reports are managed by working groups that collate and draw overall findings from the latest scientific studies and data on the physical effects of global warming around the world, how to adapt to it, and pathways for cutting planet-heating emissions in order to meet the temperature goals of the Paris Agreement.
Winston Chow, an urban climate professor at Singapore Management University who co-chairs Working Group II on adaptation, wrote in a LinkedIn post that he was “disappointed and worried” for the IPCC authors who have worked “extraordinarily hard” to assess the relevant climate science over the past two years.
He said he shared their concern that “the rigour, time and goodwill they’ve invested are now being put at risk by the Panel’s stalemate”.
As science comes under attack at UN talks, climate movement splits over how to respond
For Working Group II, a meeting for 250 experts writing that report is scheduled for January 2027, followed by the approval of a special report on cities and climate change in Singapore next March.
But because the IPCC’s budget has not been confirmed due to uncertainty about the AR7 schedule, travel support for those researchers is at risk, wrote Chow. “If they cannot participate, our assessments will lose vital expertise, perspectives and scientific breadth, and the collective effort of our authors will be undermined,” he warned.
Scientific work continues
Despite the political holdups, he – together with French climate scientist Robert Vautard, co-chair of Working Group 1 – agreed with IPCC head Skea who told the IPCC’s closing session on Friday: “The engine room of the IPCC is working, and it’s healthy.”
Vautard commented in a separate post on LinkedIn after it ended: “The boat is at full steam.” Working groups I and II are due to start revising the first drafts of their reports, while Working Group III on reducing emissions is finalising its first draft which will be out soon, he wrote.
“The most exciting two years of the cycle are ahead, for the authors. The momentum in the engine room is here and now. Trust the engine room!” he added.
The IPCC and some scientists report that progress has been made towards achieving an equitable balance of authors from the Global North and the Global South.
The group of researchers who signed the open letter on Monday noted that “inclusivity is at the heart of how we work”, with author teams bringing together experts from developed and developing countries with diverse backgrounds and at different stages of their careers.


Plea to overcome political differences
The signatories include several scientists from some of the countries opposed to the alignment of all IPCC reports with the Global Stocktake.
“We are committed to an assessment in which the knowledge, experience and priorities of every region are fully reflected, a commitment we share with the leadership of the IPCC.
Equity is built into how our assessment is being drafted,” they added.
They appealed to governments that make up the IPCC “to overcome their political differences and work together as we do as a global scientific community, so that we can deliver the IPCC reports the world needs to hear”.
In a statement published on Monday, IPCC chair Skea said reaching consensus on the schedule for the reports is “vital”. He added that the assessments provide authoritative scientific evidence to inform national climate policies, strengthen adaptation and resilience and support access to climate finance, as well as helping communicate the scale of the climate crisis and the urgency of efforts to tackle it.

Protecting nature is a public duty, not a Wall Street profit opportunity
An Lambrechts is a biodiversity politics expert at Greenpeace International with extensive experience in biodiversity-related multilateral negotiations. She is the head of the Greenpeace delegation at the Convention on Biological Diversity (CBD) COP17 happening in Yerevan, Armenia.
In 2022, COP15 delivered the landmark Kunming-Montreal Global Biodiversity Framework to halt and reverse biodiversity loss by 2030. With COP17 starting in Yerevan, we are now halfway to the deadline, and according to the first Global Review of progress, countries are not on track to meet the biodiversity targets, and implementation must accelerate fast.
One of the main findings of the Global Review is that funding falls far short of the scale needed to halt and reverse nature loss. But the crisis facing the world’s biodiversity is not an absolute scarcity of capital – it is a profound public policy distortion.
The global economy currently spends roughly $30 destroying nature for every single dollar invested in its protection. According to a report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, a staggering $2.4 trillion is spent in public subsidies for fossil fuels, agriculture and water use, while global investment in biodiversity conservation and restoration stands at a mere $220 billion.
Countries urged to ramp up “insufficient” nature policies at COP17
Yet, discussions about how to close the biodiversity finance gap continue to claim that salvation lies in mobilising private capital, scaling offsets and “derisking” investments in nature. This is a fundamental misunderstanding of both the nature of ecological stewardship and of the global financial architecture.
Biodiversity conservation is not a speculative investment portfolio – it is the foundation of human survival. The health of our planet is a non-monetisable, non-excludable public good. Expecting profit-seeking private capital to protect nature perpetuates the structural drivers of ecosystem destruction in the first place.
But if private market mechanisms cannot save biodiversity, where will the necessary public resources come from?
Money going to the wrong places
The answer lies in recovering the vast public wealth currently drained by cross-border tax abuse, financial secrecy and corporate impunity. Finance and environment ministers meeting in Yerevan must give a strong political signal that, to avert ecological breakdown, countries need to take swift action to reform global tax rules, eliminate harmful public subsidies and cancel unsustainable sovereign debts for the public revenues to end up where they belong.
Extractive sectors such as industrial agriculture, fishing, timber and mining continue business-as-usual, often heavily subsidised by public treasuries, while voluntary carbon and biodiversity offset markets pose a serious risk to nature conservation. Offset schemes have delivered only a negligible fraction of the funding needed to preserve ecosystems, allowing industries to continue with their destructive business-as-usual practices.
