Cop30 live: crucial climate talks begin in Brazil as hosts insist summit must lead to ‘implementation’

The F word: fossil fuels
In today’s statement, the 25 UN special rapporteurs also repeated calls made by climate justice activists for years now, that the UNFCCC ban fossil fuel lobbyists from the climate negotiations.

We reiterate the need to curb the presence of fossil fuel lobbyists at the Climate COP, and ensure transparency, public participation, meaningful dialogue with civil society, and effective protection of environmental human rights defenders and their associations. These are all necessary conditions for more effective and just climate action.

On Friday, we published exclusive research by the Kick Big Polluters Out Coalition that illustrated why this matters.
More than 5,350 lobbyists representing the interests of the oil, gas and coal industries were allowed to participate in the previous four climate summits. These lobbyists, who were allowed to mingle with world leaders and climate negotiators, worked for at least 859 fossil fuel organizations including trade groups and 180 oil, gas and coal companies involved in every part of the supply chain from exploration and production to distribution and equipment.
The figures do not even include fossil fuel representatives on official country delegations or those on behalf of other major polluting industries such as industrialized agriculture, aviation, and Big Tech.
So why do they come? Just 90 of the fossil fuel corporations including ExxonMobile, Chevron, BP and Petrobas which sent some of the highest number of lobbyists, accounted for 57% of all the oil and gas produced last year - and almost two-thirds of all short-term upstream expansion projects which are gearing up for exploration and production.
The fossil fuel companies - and other polluting industries - send representatives to the climate negotiations in order to influence climate policy. Advocates and many climate vulnerable countries want them kicked because they have been successful in helping to delay and block meaningful climate action for decades. Adilson Vieira, spokesperson for the Amazonian Work Group, said:

This information clearly exposes corporate capture of the global climate process … the space that should be about science and the people has been transformed into a large carbon business hall. While forest communities fight for survival, the same companies that cause climate collapse buy credentials and political influence to continue expanding their fossil empires.”

Hello, this is Nina Lakhani, climate justice reporter, taking over our blog from my colleague Damien Gayle for the rest of today.
This is the first UN Cop summit since the landmark climate ruling by the International Court of Justice (ICJ) in July, which clarified that all states - whether they are signed up to the Paris agreement or not - are bound under international law to to act with due diligence to prevent, mitigate and remedy harms to the climate system.
The ICJ judges rejected arguments from high polluting countries who opposed the case spearheaded by Vanuatu – including the US, UK, China, the EU, Russia and Saudi Arabia – that their obligations were limited to the consensus based climate regime, that is the UN framework convention on climate change, Kyoto protocol and Paris agreement.
Rather, the ICJ affirmed that every person has a human right to a “clean, healthy and sustainable” environment – a prerequisite for enjoying universal foundational rights such as life, health, food, water and housing. The court also confirmed that the onus is on the industrialised wealthy countries that have contributed most to the crisis to act first.
A short while ago, 25 UN experts including the special rapporteurs on climate change, Indigenous peoples and education, and a variety of other human rights issues, released a joint statement calling for “full compliance” with the ICJ ruling, along with a ban on fossil fuel lobbyists and more transparency as crucial steps in achieving just climate action. The UN experts said:

The credibility of the climate COP30 as a whole depends on achieving a meaningful outcome on mitigation and international financial and technological cooperation, with specific reference to fossil fuels and related subsidies as the main drivers of climate change and their impacts on human rights, including health, economic equality, adequate standard of living, education, and cultural rights.

So while the big polluters may want Cop30 to be business as usual, the landmark ICJ climate ruling is clear that failing to take decisive action on fossil fuels would be a violation of international law.
So what impact could or should the ICJ opinion have on the negotiations and domestic climate policies? This is something we’ll be keeping a very close eye on throughout Cop30.

A dozen countries have pledged to formally recognise land rights across 80 million hectares where Indigenous, Afro-descendant and other communities live in tropical forests around the world by 2030 in a bid to stem global deforestation, Reuters reports.
The Intergovernmental Land Tenure Pledge, billed as the first global commitment recognising land tenure to secure additional land under Indigenous communities’ control, was announced on Friday ahead of the Cop30 climate summit that kicked off Monday.
So far nine tropical forest nations - Brazil, Costa Rica, Colombia, Democratic Republic of Congo, Ecuador, Fiji, Indonesia, Pakistan and Tanzania - have signed the commitment with more countries expected to follow, a pledge document showed.
The document, a final version of which is expected to be released on 17 November, states land rights and protection should be strengthened in another 80 million hectares that have already been formally recognised.

Brazil's Cop30 president formally opens the climate summit

Brazil’s Cop30 president, the veteran climate diplomat André Corrêa do Lago, has formally declared the conference open, writes Jonathan Watts, the Guardian’s international climate editor.Echoing a statement made by Brazil’s president in the run-up to the climate talks, do Lago said Belém would be the “Cop of Truth” and stressed the importance of urgency, given the growing impact of climate disasters, most recently in Brazil, the Philippines and Jamaica.
He said the Cop process was making a difference, but needed to move faster: “Remember that the Paris Agreement 10 years ago was at the time when it was predicted that we would exceed four degrees of temperature and today we know that we reduced it. But we also know that we have to work hard to reduce it more.”
Setting out the host’s priority for the world to accelerate implementation of commitments and policies, do Lago said he hoped “this would be an adaptation Cop, a Cop that will advance the integration of climate into the economy, job creation activities and most of all a copy that will listen and believe in science.”
Luiz Inácio Lula da Silva, Brazil’s president, stressed the importance of emissions reductions during this Cop, even though it is not on the formal agenda. “We need a road map so that humanity...can overcome its dependence on fossil fuels,” he said.
He stressed the importance of reducing deforestation and putting people at the heart of climate action, particularly indigenous communities.
Lula launched a fierce attack on those who spread fear and attacked science – an apparently veiled reference to Donald Trump, the US president, who has constantly called climate action a “hoax” and bullied smaller nations into weakening action on maritime emissions.
In a defence of the Paris Agreement, he said the world would be doomed to catastrophic warming of 5C by the end of this century if it were not for multilateral negotiations. “We are moving in the right direction,” he said, but emphasised the need for more urgency in implementation of policies.
Despite the criticism of the high prices and logistical challenges of hosting a COP in the Amazon rainforest, he said the host city had done an exceptional job. “I hope the serenity of the forest inspires in all of us much-needed clarity of thought,” he concluded.
Mukhtar Babayev, Azerbaijan’s minister for ecology and the president of the previous Cop in Baku, passed the baton to Brazil at the opening session of COP30.
He stressed the importance of building on the climate finance commitments made last year, when wealthy nations agreed to provide $300bn annually by 2035, with a broader aspiration to scale this up to 1.3trillion a year with support from private sources.
“Delivering the Baku finance goal will be essential to success,” he said. “We ask vulnerable Communities to accept the limits of how much support they could expect. Now in eagle measure we see the donors deliver in full with developed countries taking the lead.”

While the Trump administration is steering clear of Belém this month, Dharna Noor, Guardian US fossil fuels and climate reporter, last week wrote that dozens of US subnational leaders are planning to attend to promote their climate efforts.
“Whatever our nationalised policy is or isn’t, the people on the ground locally are getting it done, committing to partnerships and economic development that will last generations and create the kind of clean energy future we are all relying on,” said New Mexico’s governor, Michelle Lujan Grisham, on a press call.
Grisham, who addressed reporters from from a pre-Cop30 summit in Brazil, will travel to the negotiations with more than 100 other state and local US leaders. Organized by the subnational climate coalitions America Is All In, Climate Mayors, and the US Climate Alliance, the group will also include the Wisconsin governor, Tony Evers, Phoenix mayor, Kate Gallego, and others.

The US’s absence in Belem is notable, writes Oliver Milman, Guardian US environment correspondent. There is no official American pavilion alongside those of other major powers, no government officials, not even embassy help for the few US members of Congress who have attempted to get here amid a shutdown in Washington.Given the hostility of the Trump administration to any sort of climate action, though, many diplomats are privately relieved that the US is staying away. They have feared a repeat of the bully-like tactics that the US recently used to stymie planned rules to curb planet-heating emissions from the shipping sector.The Trump administration could show up and cause some fireworks next year, though, according to Chris Wright, the US energy secretary. Speaking at a business summit in Greece on Friday, some 5,000 miles away from Brazil, Wright said he may attend next year’s Cop “just to try to deliver some common sense.”“It’s essentially a hoax. It’s not an honest organisation looking to better human lives,” Wright told the Associated Press of the Cop gatherings.

Mana Omar, 29, is the Executive Director and Founder of Spring of the Arid & Semi-Arid Lands (Sasal) and a dedicated advocate for climate justice and gender equality among Kenya’s indigenous pastoralist communities, writes Aseel Mousa, Guardian reporter.
She will be attending COP as an individual representing her organisation, continuing her active engagement in climate negotiations since COP27 in Egypt. Her motivation to participate in this year’s COP — hosted in Brazil — stems from its focus on indigenous issues.

As an indigenous woman from Kenya, I am passionate about amplifying African indigenous voices, which I feel are often overlooked compared to those from Latin America. Through my public speaking, advocacy, and media engagement, I work to ensure that African indigenous perspectives are recognized and included in global climate discussions.

Mana’s primary area of focus is climate finance, particularly the Loss and Damage Fund.

Adaptation alone is insufficient for communities already suffering from severe climate impacts. In Kenya’s arid and semi-arid regions—covering around 83% of the country—prolonged droughts, failed rains, and rising temperatures have devastated agriculture and livestock, leading to cascading social challenges such as income loss, reduced access to education, gender-based violence, and mental health issues.”
Despite my commitment, I often feel frustrated with COP’s outcomes. I see a systemic exclusion of those most affected by climate change from key decision-making spaces, and even the Loss and Damage Fund’s board largely represents high-emission countries. Although I remain skeptical about seeing immediate progress, I still believe in the long-term power of persistent advocacy and collaboration among those who share the same vision for justice and inclusion.

Jamaica's former climate change director calls for hurricane accountability

UnaMay Gordon, former director of climate change for the government of Jamaica, had some strong words for big polluters on the opening day of Cop30.
The climate summit comes as huge parts of Jamaica lie devastated by Hurricane Melissa, a category five storm with winds up up to 185mph (298km/h) that slammed into the Caribbean island last month.
Last week team of scientists reported that they had found that every aspect of Melissa, the most powerful hurricane ever to hit Jamaica, was made worse by climate breakdown.
“Every single Jamaican now knows the words catastrophic loss,” Gordon, now a senior associate at the International Institute for Environment and Development.

Within a day of Melissa’s passing, Jamaica became the world’s symbol of climate devastation. [Cop30] therefore needs to prove to the world that it is a symbol of climate action.
I am here to ask where the accountability is. I am here to ask who should pay, the people responsible, we are asking you to take responsibility and start to pay up. While the US is not here, there are a lot of major emitters here on the ground and they have to stop talking, they have to help us to survive.When we fought for 1.5C [at the Paris climate summit in 2015], we were fighting for our survival. That was 10 years ago and we are still fighting for survival. Every single life lost is your responsibility.

Governments failing to shift to a low-carbon economy will be blamed for famine and conflict abroad, and will face stagnation and rising inflation at home, the UN’s climate chief warned at the start of the Cop30 climate talks, writes Fiona Harvey, Guardian environment editor.
Simon Stiell, the executive secretary of the UN framework convention on climate change, addressed the gathering of ministers and high-ranking officials from nearly 200 countries, in a stark portrayal of the price of failure on the climate crisis.
“Not one single nation among you can afford this, as climate disasters rip double digits off GDP,” he warned. “To falter whilst mega droughts wreck national harvests, sending food prices soaring, makes zero sense, economically and politically. To squabble while famines take hold, forcing millions to flee their homelands, this will never be forgotten, as conflicts spread.”
He told the opening meeting of the UN climate summit: “When climate disasters decimate the lives of millions, when we already have the solutions, this will never, ever be forgiven.”

Hundreds lined up for Cop30 on opening morning, with some in Indigenous headdresses and others in trouser suits, writes Dharna Noor, fossil fuels and climate reporter for the Guardian US.
The conference is being held in a massive temporary building in Belem’s Parque da Cidade area. It was still under construction just days ago, but now seems to be ready to use.
Upon entering the conference venue, participants were immediately greeted by a sprawl of national pavilions, where countries will show off their climate bonafides at speeches and roundtables. Close to the entrance, side by side, sit pavilions for Turkey and Australia, which are currently in a bitter standoff over who will host next year’s Cop31 climate talks.
Some countries have gone all out with their pavilions this year. Malaysia’s says it will include a “virtual rainforest,” billed an “immersive experience,” while Indonesia’s will feature traditional dancing. China’s booth features free paper fans adorned with calligraphy, handmade for each participant. At Brazil’s pavilion, I waited in a too-long line for what turned out to be a small splash of coffee.
Conspicuously absent from the maze of booths: the US. The world’s largest historical emitter, lead by climate denier Donald Trump, has chosen not to send a delegation this year.
The drab, grey halls of the Cop30 venue were full by 8am on Monday morning. Some delegates were hugging or shaking hands. Others were whispering to one another with concerned facial expressions. Still others were queueing up for coffee or pastries, seemingly bewildered by the new cashless system that conference organisers have implemented for purchases of food and drink this year.
Though the main halls were packed, the media centre appeared stunningly empty, with entire tables going unused. Perhaps it’s too early to tell, but it appears fewer outlets are sending big teams to cover the conference, even though some have called it the most consequential Cop since the Paris climate agreement was signed a decade ago.

The opening plenary is starting now. Mukhtar Babayev, Azerbaijan’s minister for ecology and the president of the previous COP in Baku has passed the baton to Brazil.

Governments are failing to address child hunger and malnutrition in the context of climate change, the charity World Vision has warned.
To mark the beginning of the Cop30 climate talks, World Vision has published an analysis of 84 national climate plans to assess how well governments are addressing hunger and nutrition in the context of the climate crisis.
The charity found four-fifths to be failing, with less than 20% of countries even mentioning child hunger in their plans, and even fewer mentioning child malnutrition or budgeting to address the impacts.
World Vision pointed out that almost one-third of the world’s population – about 2.6bn people – cannot afford a healthy diet. The charity said this figure could rise by 20% by 2050 as a result of climate breakdown.
Kate Shaw, senior advisor at World Vision International, said:

When children are invisible in data, budgets, and strategies, they are invisible in the solutions that shape their lives. Policies that fail to track how resources reach girls and boys are failing the very generation most affected by the climate crisis.
We are entering an age of hungry futures. Children are on the frontlines of climate change, yet their needs and voices are almost invisible in the world’s climate blueprints. COP30 in Brazil must be a turning point. Children cannot be an afterthought in climate policy - they must be at the heart of it.

Could a cold war emerge between fossil-fuel-powered petrostates and states embracing the accelerating transition towards electrifying everything? Some observers think so and a quiet deal made on the eve of Cop30 hints in that direction, writes Damian Carrington, Guardian environment editor.
China and the European Union have agreed to join a coalition to harmonise carbon markets between countries, Bloomberg reported. The UK, Canada, France, Germany, Mexico, Chile, and Zambia are also on board.
National emission trading systems usually set a cap on total emissions, with companies emitting less than their quota able to sell permits to those that exceed theirs. But there are more than 35 different emissions trading systems in the world.
Harmonising these could unify major blocs of nations, all operating under the same rules which would ease free trade between them. The significance is that this would exclude petrostates refusing to play by the same rules as the world works to slash the emissions driving the climate crisis. These nations, such as Saudi Arabia, Russia and – under Donald Trump – the US, might face border tariffs on their high-carbon goods.
In this scenario, the world could divide into opposing blocs of electrostates and petrostates. Which bloc might prevail is up for discussion, but the Economist noted this week: “China is now making more money from exporting green technology than the US makes from exporting fossil fuels.”

The global south has put the north to shame in the run up to the Cop30 climate conference in Belém, writes Jonathan Watts, the Guardian’s global environment editor.
From heartrending testimonies of extreme weather disasters and conflicts exacerbated by droughts to inspiring examples of ambition in their climate plans, the less developed nations of the world have shown they are willing to step up and face the climate crisis even as some of the wealthiest countries most responsible for it walk away.
Ahead of the two-week gathering, only 106 out of 194 nations that signed up to the Paris agreement have submitted updated climate plans, known as nationally determined contributions (NDCs). This is down by a third from Cop26 in 2021. More than half of those who submitted were from the global south. The omissions include at least five of the G20 group of wealthy countries - Russia, Argentina, South Korea, Turkey and Saudi Arabia - according to the latest United Nations register of NDCs.
The number of presidents and prime ministers who attended last week’s climate summit is also down from previous editions. At its conclusion, only 44 leaders signed the Belém declaration, which warned: “Climate change, environmental degradation, and biodiversity loss are worsening hunger, poverty, and food insecurity.”
The planet’s three biggest emitters - China, the US and India – did not send state leaders to Belém, though the latter two nations at least sent representatives to address the gathering in a constructive manner.
The absences allowed Trump, Xi and Modi to avoid hearing of the horrifying experiences and requests for help from their counterparts in poorer nations who are suffering the consequences of those still-rising emissions. Delegate after delegate from Africa, Asia and South America stated that dire climate impacts are now the lived reality for millions of their people.
Tuvalu climate minister Maina Vakafua Talia said the US withdrawal from the Paris agreement and Trump’s denial of climate science showed “a shameful disregard for the rest of the world.” He said the dangers of inaction were evident in recent disasters like Hurricane Mellissa, which devastated Jamaica, Cuba and others Caribbean islands, and Typhoon Tino, which has killed more than 188 people in the Philippines. “The more we warm our oceans the more extreme these weather events are becoming,” he said. “There is no time in history when the world has faced such a threat.”
Pakistan’s climate secretary, Aisha Humera, said the climate crisis was the biggest human rights violation of our time. She said a 2022 a superflood had inundated a third of her country and caused $30bn dollars of damage. “We thought that was a one-in-a-century event, but just three years later we faced another flood of catastrophic proportions, washing away lives and livelihoods.” In Pakistan’s mountains, she said 13,000 glaciers were melting at unprecedented rates. “Recurring glacial outburst floods have become an annual nightmare,” she said. “This is not a cycle of disaster, it is a escalating cascade.”
Like several other climate afflicted countries, she said Pakistan needed the wealthy nations of the world, which were most to blame for the climate disasters, to face up to their responsibilities and make good on promises of financial support: “From the frontline of this crisis, we demand that we operationalise the loss-and-damage fund with billions not millions and make it available to countries like Pakistan.”
The grimmest testimonies came from delegates from war-torn nations who described how climate-induced problems were amplifying the damage afflicted by conflict. Even so, they had made the efforts to update their NDCs.
The ambassador of Sudan, Ahmed Eltigani Mohamed Swar, painted a nightmarish picture of climate collapse and violence: “An unprecedented rise in temperatures, along with recurring waves of drought and desertification. Devastating floods that threaten the livelihoods and food security of millions of citizens” and “armed conflicts that exacerbate the fragility of the state and drain its resources.” Outlining a vicious cycle, he said air and water pollution had also deteriorated due to attacks on industrial plants, oil storage facilities and forests. Despite this he said Sudan continues its unwavering commitment to the goals of the Paris agreement and was striving to implement its climate plans in the agriculture, energy and water sectors.
Palestine’s ambassador, Ibrahim Al-Zaben, said climate change intensified the already dire situation imposed on his people by the 58-year Israeli military occupation and more recent “war of extermination.” He described a worsening shortage of water and food, collapsing sewage systems and grave risks to public health. Despite the grim situation in Gaza, where he said there were a quarter of a million victims of the Israeli army, he spelled out how Palestine was trying to take steps to upgrade its climate plans and improve its sustainability and transparency. He called for global solidarity to stop greenhouse gas emissions, secure climate finance and improve environmental justice. In the face of all the challenges, he said Palestine remained steadfast. “Our message to the world and our appeal from this platform is a message of hope, resilience, and determination to contribute to a just, sustainable, peaceful, and free future, not only for our people but for our planet, for our future generations.”
While many observers in the global north lament the decline in the climate consensus, multilateralism and overseas development aid as inexorable, the hosts and many delegates at last week’s Belém summit spelled out alternatives and stressed the need for political solidarity.
One of the primary bones of contention is climate funding. On 5 November, Brazil and Azerbaijian (the hosts of last year’s and this year’s COP) unveiled a Baku-Belém Roadmap to raise $1.3tn so that poorer nations could cope with the climate crisis. The authors said the funds were available, noting that the target was less than 1% of the $180tn managed by pension funds and insurers worldwide. They said political will was needed to channel this money where it was needed more.
Some wealthier nations and groups, including the EU said they were aware of the need to support the worst-affected countries, but there were few specifics. Meanwhile the World Bank, other international institutions and many governments continue to pour huge sums into subsidising fossil fuels. A huge gap remains in financing expectations and delivery. Movement in this area will be key to a successful conference.
Most of the western media has blamed the low participation rates in Belém on a lack of accommodation and high prices, but this too is shifting responsibility onto the global south. There are certainly infrastructure problems, which is not surprising given this Amazonian municipality is one of the poorest host cities in the history of the Cop and one of the worst affected by rising temperatures. But a bigger reason for the weak turnout is just as likely to be that rich, high-emitting countries are turning their backs on the parts of the world that they have lived off for centuries and now condemn by their slow or non-existent action to phase out fossil fuel emissions.

Rich countries have lost enthusiasm for combating the climate crisis while China is surging ahead in producing and using clean energy equipment, the president of the UN climate talks has said, writes Fiona Harvey, Guardian environment editor.
More countries should follow China’s lead instead of complaining about being outcompeted, said André Corrêa do Lago, the Brazilian diplomat in charge of the Cop30 conference, which begins on Monday.
“Somehow the reduction in enthusiasm of the global north is showing that the global south is moving,” Corrêa do Lago told reporters in Belém, the city in the Amazonian rainforest where the fortnight-long Cop30 conference is taking place. “It is not just this year, it has been moving for years, but it did not have the exposure that it has now.”
He pointed to the world’s biggest emitter of greenhouse gases, China, which is also the biggest producer and consumer of low-carbon energy. “China is coming up with solutions that are for everyone, not just China,” he said. “Solar panels are cheaper, they’re so competitive [compared with fossil fuel energy] that they are everywhere now. If you’re thinking of climate change, this is good.”
Ministers and high-ranking officials from 194 countries will seek to forge plans at Cop30 to stay within, or as close as possible to, the limit of 1.5C of heating set out in the Paris agreement, to set a roadmap to phase out fossil fuels, and to ensure that poor countries receive the help they need.
Top of the agenda will be national plans on cutting greenhouse gas emissions, which currently would lead to a devastating 2.5C of heating. Vulnerable countries want to draw up a plan that will show how countries can outdo their current inadequate efforts and meet the Paris agreement targets.

12.33pm GMT

We try our best, but high level negotiations do not always make for the most-compelling news coverage. Nevertheless, it is still disappointing that UK national papers dedicated more space to advertising high carbon travel than to coverage of last year’s Cop talks.
According to research by the New Weather Institute, for the Badvertising campaign, UK papers gave 1,745 column inches over to advertisements for flights and cruises, compared to 1,540 inches to reporting on the climate talks on the key dates at the beginning and end of Cop29.
The total amount of ‘high carbon advertising’ – which includes high-carbon travel, products and services that are inseparable from the energy sector, banks who finance the fossil fuel industries, and supermarkets, which are key retailers of petrol and other high-carbon products – amounted to 5,086ins, more than three times the space given to coverage of the climate conference.
Badvertising call for a cigarette-style ban on advertising for high carbon products. The Guardian is the only national newspaper in the UK that has made a commitment to end advertising for coal, oil and gas companies.
Andrew Simms, a co-director of the New Weather Institute and a founder of the Badvertising campaign, said:

The science tells us that we must do everything possible to prevent catastrophic climate breakdown, but instead of discouraging climate pollution it is being actively promoted wherever you look, in ads for flights and big SUVs. Many climate challenges are hard, like changing energy systems and buildings, but it is easy to stop actively pushing high carbon, often luxury products and lifestyles.
Fossil fuels are like the new tobacco and we need to stop promoting them. Without action, the signal from scientists will be drowned out in the marketing noise from oil companies, airlines, and SUV makers trying to persuade us to consume as many high carbon goods and services as possible.

12.06pm GMT

There has already been significant wrangling over the Cop30 agenda, with Simon Evans, a journalist from Carbon Brief, posting on on Bluesky yesterday afternoon that the agenda was already on its fourth iteration.
“Agenda fights have been common in recent years,” Evans reports, citing similar disagreements ahead of Cop29 in Azerbaijan. The negotiations cannot actually get started until the parties agree on what it is they will talk about.
Among the potential items on the agenda are two from the “like-minded developing countries”, a bloc that includes Bolivia, China, India and Saudi Arabia, including one calling for a new, more ambitious finance goal and another for discussion of “unilateral trade-restrictive measures”.
Honduras, Suriname and Papua New Guinea want to discuss deforestation finance. Small island states want space in the agenda to discuss how to “accelerate implementation & drive ambition toward 1.5C”, with the current process “insufficient for addressing the need for accelerated action”, they say.
And the EU, meanwhile, wants to discuss reporting under Article 13, the provision of the UNFCCC which asks countries to report on their emissions.
“Many developing countries have yet to do this as required,” writes Evans. “[I] suspect this a way to put on them in response to calls for more finance…”

12.01pm GMT

Ministers and high-ranking officials from nearly 200 countries have gathered in the Amazonian city of Belem to discuss how to rein in the climate crisis, before catastrophic levels of global heating become inevitable, writes Fiona Harvey, Guardian environment editor.
On Sunday, carpenters and builders were still hard at work in the conference centre where the Cop30 UN climate summit will take place, unpacking boxes and erecting pavilions where countries will show off their commitment to tackling greenhouse gas emissions and shifting to a low-carbon economy.
By Monday, the pomp and ceremony were ready to begin. There is an element of deja vu here – world leaders have already visited Belem, jetting in last week to this same conference centre to join in round tables about climate action, preserving forests, boosting biofuels and ensuring social justice while the climate crisis bites.
More than 50 heads of state and government or their deputies took part in that “leaders’ summit” segment, on 6 and 7 November, including the UK’s Keir Starmer, the EU’s Ursula von der Leyen, and Germany’s Friedrich Merz. (Donald Trump, of course, has withdrawn the US from the Paris climate agreement and did not attend; nor did Russia’s Vladimir Putin; Xi Jinping of China and Narendra Modi of India also skipped the summit but have made friendly overtures to Brazil over Cop30.) They have all now departed and left the stage to their negotiating teams.
But these are climate talks with a difference. Brazil is refusing to countenance the standard form of tortuous negotiations that have characterised the last 30 years of nearly annual “conferences of the parties” (Cops) under the UN Framework Convention on Climate Change, the parent treaty to the Paris climate agreement, that was signed in 1992 in Rio de Janeiro.
Those were characterised by long and bitter sessions, often stretching late into the night, where negotiators re-stated entrenched positions for days on end before finally – sometimes – reaching a compromise conclusion that some present would frequently seek to back track on immediately afterwards.
Instead, Brazil insists, this will be “the Cop of implementation”. That means the real world impact of measures to combat the climate crisis today will take precedence over longwinged discussions of future promises.
“Negotiations need consensus,” said Andre Correa do Lago, president of Cop30. “But implementation is countries choosing what they want to do and executing what they have said they are going to do.”
The problem with that approach is that countries which chose to do very little may be able to get away with it. How Brazil intends to combat that tendency is yet to be seen.
The main outcomes of this Cop, instead of being a list of pledges as has become usual, are more likely to be a collection of “roadmaps” covering the key issues: a roadmap on finance, which has already been published; a roadmap on how to transition away from fossil fuels; a roadmap on how to scale up low-carbon energy and reduce greenhouse gas emissions in line with the target of limiting global heating to 1.5C above pre-industrial levels.
On some of these issues, it may not be possible to produce the final roadmap at this Cop – in the case of the transition away from fossil fuels, for instance, what is more likely is that a forum could be set up that will continue for several Cops before reporting.
Cop30 will cover enormous ground – from the future of energy, to the future of climate finance, to the need for social justice to accompany climate action. It will involve ministers, diplomats, local government officials, scientists, businesspeople, Indigenous people and representatives of all forms of civil society, from nearly every country in the world. Issues including health, biodiversity, nature, wildlife, water, the oceans, transport, migration, food, gender and technology will all be addressed at some point across the two weeks of talks.
The problem Cop exists to solve could scarcely be more urgent: scientists are warning that, as temperatures rise faster than at any point in at least 24,000 years, the world stands on the brink of a series of “tipping points” that could pitch us into greatly accelerated heating and unstoppable climate catastrophe.
But one question will dominate overall: the question of whether the collective will to solve this problem exists. Can the world come together, despite geopolitical headwinds and open conflict, despite the forces of division fanned by populism, despite the global tide of climate disinformation, despite influential voices claiming the climate somehow matters less than it did before the populists took over – and show the unity, mutual respect and spirit of cooperation that are desperately needed, if we are to face this existential threat?

Welcome to the Cop30 live blog! I’m Guardian environment correspondent Damien Gayle, and I will be taking you through the first few hours of our live coverage of the UN climate summit taking place in Belém, Brazil.
I’ll be collating all the latest dispatches from our reporters on the ground, the files from the news agencies and any bits and pieces that appear on social media to try to give you the best possible picture of the summit as it unfolds.
This morning we will see the opening plenary for Cop30, where the first point of order will be to vote on an agenda, since at the moment it remains unclear what exactly will be under discussion during the two-week summit.
Andre Correa do Lago, the Cop30 president, said countries had been wrangling for months over what to include, a process he described as a healthy exchange of priorities. Brazil’s president Lula has said he hopes countries will consider setting a plan for quitting fossil fuels, and other possible issues for the agenda include deciding how countries will cut emissions further, with their current plans falling short of what’s needed to limit extreme warming.
