Brazil’s President Luiz Inácio Lula da Silva said on Wednesday he is “optimistic” about a potential donation from the United States to the Tropical Forest Forever Facility (TFFF), a new international instrument to channel money for forest protection.
During a press conference at United Nations headquarters in New York, Lula said that, if Brazil had already pledged $1 billion to the fund, as it announced on Tuesday, “how much could the U.S. present?”
The TFFF, championed by the COP30 host nation Brazil, aims to raise money to keep forests standing in tropical countries by generating returns on investments in financial markets.
Lula’s comments came just a day after he met his US counterpart – a climate change denier – for the first time in the corridors of the UN. After the brief encounter, described by Lula as “a surprise”, Trump said they had “excellent chemistry.”

Lula said he was “very happy” with Trump’s comment, as Brazil and the US – the two largest economies in the Americas – have many industrial, technological and scientific interests in common, as well as “in the debate about digital platforms and artificial intelligence”.
In recent weeks, relations between the two countries have been frosty over Trump’s efforts to slap trade tariffs on Brazil.
Lula said multiple times that a formal meeting between the two leaders could happen soon – also mentioned by Trump – adding he would treat the US president with respect and expect the same from him. “This is what I want, and I believe that’s what he wants too.”
Praise for China’s NDC
Lula also said he had written letters to world leaders, including Trump and China’s President Xi Jinping, to personally invite them to COP30, the UN climate summit happening in November in the Brazilian state of Pará. “The US knows, people know, that the climate change issue is not something that we can joke around, fool around, and the world is in need and suffering,” he said.
On Tuesday in a long speech to the UN General Assembly, right after bumping into Lula, Trump rejected global efforts to transition to renewable energy and urged countries to keep drilling for fossil fuels – dismissing scientists’ warnings that this could set the world on a dangerous trajectory of unfettered warming. He described climate change as “the greatest con job”.
In his press conference as the climate summit continued, Lula also welcomed China’s new emissions-cutting target which its leader unveiled at the start, with the Asian giant pledging a 7-10% cut in greenhouse gas emissions by 2035 compared to “peak” levels.

Lula said he was “very happy with” with the announcement, “because China is a very big country”. He mentioned that, during COP15, the UN climate summit in Denmark in 2009 which ended in a failure to seal a new global accord, “the world wanted to throw the responsibility on the shoulders of China”, but that wouldn’t work as industrialised nations have a debt of 200 years of emitting greenhouse gases.
“But in the last years, China has advanced a lot. That’s the truth of the matter,” he added, praising the country’s energy transition and recent declining emissions.
At climate summit, UN chief urges countries to go “much further, much faster” on NDCs
As in his opening speech at the climate summit, Lula called on all governments to respect what climate scientists say, at the risk of losing credibility if they don’t.
But the only way to ensure that countries actually comply is that every time they make a decision that damages the world, they need to be punished “not in a unilateral manner, but… by the whole collective of countries”, he said.

Paris Agreement committee names three countries snubbing it over NDCs
Three countries have been named by the Paris Agreement’s compliance committee for failing to submit a nationally determined contribution (NDC) and repeatedly snubbing offers of help with their climate plans.
After months of internal debate over whether to identify serial non-responders, the Paris Agreement’s Implementation and Compliance Committee (PAICC) named the three countries which have failed to engage with it over their NDCs on Friday.
It named Democratic Republic of Congo, Senegal and North Korea in a footnote of its annual report, adding that it decided to name them “with a view to facilitating engagement”, adding that representatives of the three nations had been invited to its meeting in early 2027 “with the purpose of identifying any challenges and constraints”.
“The Committee noted the importance of Parties engaging with the Committee in a timely manner, while noting that some delays may be due to the national capabilities and circumstances of the Parties”, the report said.
In July, PAICC said 12 countries had ignored its repeated attempts to discuss why they had not published an NDC as required every five years under the 2015 Paris accord.
Members of the committee had been divided over whether to name them, but at a September meeting decided to do so in their annual report to the annual climate COP summit.
By the time the report was published on Friday, only Congo, Senegal and North Korea “had not communicated an NDC or submitted a [Biennial Transparency Report] and had not yet responded to any of the Committee’s notifications, despite several reminders issued by the Committee in this regard”.
Rainforest and renewable energy ambitions
The silence from Congo and Senegal is notable because the former is home to much of the Congo Basin rainforest while the latter has sought billions of dollars in climate finance to support its renewable energy ambitions.
After Brazil, Congo has more rainforest than any country in the world. This forest, and the country’s peatlands, absorb huge amounts of greenhouse gas but are fast being lost to expanding farmland, charcoal production, logging and mining.
Senegal signed a Just Energy Transition Partnership with Canada and wealthy European nations in 2023, to help it meet its renewable energy targets under the-then government of Macky Sall. It was chair of the Least Developed Countries group between January 2022 and December 2023.

Tejas Rao, who is researching the PAICC as part of a doctoral thesis at Cambridge University, said the governments of the three countries should engage with the committee.
“Engagement costs these governments very little and the committee has shown it will listen,” he said.
“Silence leaves the committee with no basis to help, and it leaves the [governments] exposed to the narrative that they are simply disengaged,” he told Climate Home News.
Paris Agreement requirement
The 2015 Paris Agreement requires all parties to publish an NDC every five years outlining their emissions reduction targets, with each plan meant to be more ambitious than the country’s last NDC.
The latest set – the third round of plans, with new targets for 2035 – was due in February 2025. While most countries missed this deadline, all but around 30 – mostly small emitters but including Egypt, Vietnam and Argentina – have now submitted them.
Over the year, the PAICC – which is made up of government climate officials from developed and developing countries – has been communicating with governments that have not submitted NDCs and trying to overcome barriers to them doing so.
Some nations have cited exceptional circumstances as the reason for not submitting an NDC, a process that requires a significant amount of work in tracking emissions and consulting on how to curb them across the economy. For example, a letter from a Sudanese official to the PAICC, seen by Climate Home News, said that the country’s civil war had led to the suspension of its NDC preparation.
The US and Iran are not signed up to the Paris Agreement and so do not have active NDCs, nor does Taiwan, which is not a UN member state.
Rao said that because the PAICC is “facilitative and non-punitive”, naming the countries “is meant to open a door, not close one – the invited consultation is the point”.
“In recent months, governments that explained their constraints, whether capacity, finance or domestic process, have been met with follow-up and support rather than sanction, and the number of silent governments has fallen sharply,” Rao said.

Q&A: Why a pivotal IPCC meeting in Ethiopia ended in ‘profound disappointment’
Countries have failed – for the sixth time running – to agree on the timeline for publishing the Intergovernmental Panel on Climate Change’s (IPCC) next set of influential reports.
The IPCC’s 65th session (IPCC-65) was seen by many to be the final opportunity for countries to agree on a schedule where its seventh assessment report (AR7) would be published in time for the UN’s second “global stocktake” of climate action.
Before last week’s meeting in Addis Ababa, Ethiopia, IPCC chair Prof Sir Jim Skea had warned that releasing the reports in time for the stocktake in 2028 would depend on a timelines being agreed by the end of 2026.
But the week-long meeting descended into fraught disagreements between governments, resulting in Skea “suspending” the talks on Friday evening with no decision made.
Countries were also unable to agree on the IPCC’s budget for the rest of the AR7 cycle, leaving the body with a “serious funding crisis”.
The IPCC has pledged to reconvene the meeting at the “earliest opportunity”; however, it has not yet given an indication of when this will be.
In his concluding remarks, Skea described the Addis Ababa summit as a “profound disappointment” and “among the most difficult IPCC meetings”, according to reporting from the Earth Negotiations Bulletin (ENB).
Some countries have reacted with dismay to the breakdown of negotiations, warning that a failure to have the IPCC’s latest assessments on climate adaptation and mitigation ready for the UN stocktaking exercise would undermine global climate action.
A climate envoy from a Pacific island state said it was a “travesty that a handful of countries continue to delay the IPCC’s reports – the science we need back home to help us save lives and livelihoods”.

What timeline options were delegates debating?
Top of the agenda during the Addis Ababa meeting was a decision on the timeline of the publication of AR7’s three working group reports – also known as the “work plan”. The three reports cover climate science (WG1), impacts and adaptation (WG2) and mitigation (WG3).
Countries failed to reach a resolution on the scheduling of the influential reports at five consecutive IPCC meetings since 2024 – despite drafting being well underway.

Reporting from the ENB from inside these meetings has highlighted that countries are split, broadly, into two groups – those that want all three reports to be published in time for the UN’s second “global stocktake” in 2028, and those that one, or more, to be published afterwards.
