The first three quarters of 2023 has seen exceptional heat globally, putting 2023 on track to be the warmest year since records began in the mid-1800s, and likely for millennia before as well.
The past four months, in particular, have far exceeded any prior records, with September smashing the prior record by around 0.5C.
In this latest “state of the climate” quarterly update, Carbon Brief finds:
- June, July, August, September and (very likely) October were the warmest respective months since records began.
- 2023 is now virtually certain to be the hottest year on record globally.
- A strong El Niño is expected to persist until mid-2024 in the majority of El Niño Southern Oscillation (ENSO) forecast models.
- October is likely to be extremely warm based on daily data so far, though not quite as unusual as September.
- While the exceptional warmth of the last few months is primarily driven by a strong El Niño on top of human-driven warming, other contributing factors include an uptick in the 11-year solar cycle, an unusual volcanic eruption last year and a 2020 phaseout of planet-cooling sulphur dioxide in marine shipping fuels.
- Ocean heat content set a new record in September and has increased substantially over the past 12 months.
- Antarctic sea ice has been exceptionally far below the prior record low for the past six months, while Arctic sea ice remains at the low end of the historical range.
- Global temperatures are closely aligned with the projections from climate models.
Global temperatures have soared in recent months
After a cool start due to an unusually persistent “triple dip” La Niña event, global temperatures have soared in recent months driven by rapidly growing El Niño conditions.
This short-term natural variability builds on top of the roughly 1.3C warming that has occurred since the mid-1800s due to human emissions of CO2 and other greenhouse gases.
The figure below shows how global temperature so far in 2023 (black line) compares to each month in different years over the prior decade (coloured lines) in the Berkeley Earth surface temperature dataset.
Temperatures for each month from 2015 to 2023 from Berkeley Earth. Anomalies plotted with respect to a 1850-99 baseline. Chart by Carbon Brief.
Every month from June onward this year has set a clear record, with July, August and September shattering prior records by at least 0.3C (and around 0.5C in the case of September). The exceptional summer warmth means that it is now virtually certain that 2023 will be the warmest year on record.
In this latest quarterly state of the climate assessment, Carbon Brief analysed records from five different research groups that report global surface temperature records: NASA’s GISTEMP; NOAA’s GlobalTemp; Hadley/UEA’s HadCRUT5; Berkeley Earth; and Copernicus/ECMWF.
The figure below shows the annual temperatures from each of these groups since 1970, along with the average over the first nine months of 2023. (Note: at the time of writing, September data was not yet available for the Hadley/UEA record.)
Annual global mean surface temperatures from NASA GISTEMP, NOAA GlobalTemp, Hadley/UEA HadCRUT5, Berkeley Earth and Copernicus/ECMWF (lines), along with 2023 temperatures to date (January-September, coloured shapes). Each series is aligned by using a 1981-2010 baseline, with warming since pre-industrial based on HadCRUT5 values from the 1850-1899 to 1981-2010 periods. Chart by Carbon Brief.
The globe as a whole has warmed around 1C since 1970, with strong agreement between different global temperature records. All show that year-to-date 2023 records are higher than any prior annual record. However, there are larger differences between temperature records further back in time (particularly pre-1900) due to sparser observations and a resulting greater sensitivity to how gaps between measurements are filled in.
This year started out a bit on the colder side in all the different temperature records, with January only the seventh warmest January on record and February only the fourth or fifth warmest. March was the second warmest on record, April the fourth or fifth, and May the third warmest across all datasets.
However, from June onward each month has been unambiguously the warmest on record across all the different datasets. The respective rankings of each month in each dataset are shown below.
| GISTEMP | HadCRUT5 | NOAA | Berkeley | Copernicus | |
|---|---|---|---|---|---|
| Jan | 7th | 7th | 7th | 7th | 7th |
| Feb | 4th | 4th | 4th | 5th | 5th |
| Mar | 2nd | 2nd | 2nd | 2nd | 2nd |
| April | 4th | 4th | 5th | 4th | 5th |
| May | 3rd | 3rd | 3rd | 3rd | 3rd |
| June | 1st | 1st | 1st | 1st | 1st |
| July | 1st | 1st | 1st | 1st | 1st |

Rankings of 2023 global temperature by month across different datasets.
The continued strengthening of El Niño over the next few months means that it is likely that this streak of record-setting warmth will continue.
The figure below shows a range of different ENSO forecast models produced by different scientific groups. The values shown are sea surface temperature variations in the tropical Pacific – the El Niño 3.4 region – for three-month periods.
Virtually all models expect El Niño conditions to remain until early-to-mid 2024. Most models project a strong El Niño (>1.5C Niño 3.4 sea surface temperature – SST – anomaly), but relatively few expect a “super El Niño” (>2.5C) as strong as the world saw in 2015-16 or 1997-98.
Extreme heat worldwide
Record-setting global temperatures contributed to record heatwaves in many regions over the recent northern-hemisphere summer. The figure below shows the parts of the world that saw record warm or cold temperatures over the first two-thirds of 2023 (January through to September) in the Berkeley Earth dataset.
Large parts of the North Atlantic saw record warm temperatures, as did the UK, large parts of Europe, the southern US and Mexico, Central America, South America, the Caribbean, Korea, Japan and China.
Notably, no area on Earth saw record cold (or even the second-to-fifth coldest temperatures on record).
In September alone, 77 different countries – mostly in Europe and the tropics – set new monthly average records.
Virtually everywhere on the planet saw warmer-than-usual temperatures for the year so far, with the exception of the western US, India and Greenland.
The tropical Pacific shows a strong characteristic “warm tongue” associated with El Niño over the first nine months of the year. The global temperature anomalies (changes) relative to the 1951-80 period used by Berkeley Earth are shown in the map below.
October continuing the record warm streak
While global temperature records are not yet in for the full month of October 2023, real-time reanalysis products increasingly allow scientists to track global temperatures on a daily basis.
Reanalysis pulls together a huge amount of data from satellites, weather balloons, aeroplanes, weather stations, ships and buoys to provide a detailed look at how the Earth’s climate is changing in real-time.
Modern reanalysis products, such as JRA-55 and ERA5, use state-of-the-art methods to produce records that align well with traditional surface temperature datasets over recent decades.
In the figure below, Carbon Brief shows the daily global temperature anomaly values from the JRA-55 reanalysis product for each day since the record began in 1958 (grey lines). It shows the current year to date (2023) in red and the prior record warm year, 2016, in blue. Nearly every single day since mid-June 2023 has been warmer than any prior days since the JRA-55 record began in 1958 – and, potentially, much further into the past.
The heat map below focuses on 2023, showing each day in the year, with columns representing each month. The red shading shows the temperature anomaly of each day, with darker shading indicating more extreme temperatures. The map highlights how extreme the prior four months (from July onward) have been compared to the prior period.
With most of the data for the month of October now available in the JRA-55 reanalysis product, Carbon Brief estimates that October 2023 will be the warmest October on record, and is likely to exceed the prior record by at least 0.3C.
The figure below shows Carbon Brief’s estimate for October, with uncertainty intervals estimates based on the historical relationship between the first 19 days of the month available at the time of publication and the overall monthly average.
October is projected to not be quite as extreme as September’s record-shattering anomaly, but will still come in as the second highest anomaly of any month in 2023 to-date.
In addition to temperature anomalies, reanalysis products are able to provide an accurate near-real-time estimate of global absolute temperatures. The figure below shows the absolute temperature of each month of 2023 compared to all prior years in the record, with Carbon Brief’s October estimate and its uncertainties shown.
Unpacking the drivers of recent record warmth
The extreme surface temperatures seen over the past few months have triggered a broader debate in the scientific community around its potential drivers.
For example, the world has never seen a month exceed the prior monthly record by 0.5C – as experienced in September. The closest analogue is February 2016, where global temperatures beat the prior record by 0.47C.
However, February 2016 was shortly after the peak of a super El Niño event – when the effect of El Niño on global temperatures is expected to be the largest. September 2023, by contrast, occurred early in the evolution of the current El Niño event when the contribution to global temperatures is typically much smaller.
This has led to a search for alternative explanations of factors contributing to recent record warmth. While the rapid switch from modest La Niña conditions at the start of the year to growing El Niño conditions on top of human-driven warming remains the primary explanation, it cannot easily explain the full extent of extreme global temperatures over the past few months.
A number of different potential contributors to recent global temperature records have been identified, including an uptick in the 11-year solar cycle, an unusual volcanic eruption last year that put a large amount of water vapour into the stratosphere with minimal cooling sulphate aerosols, and a 2020 phaseout of planet-cooling sulphur dioxide in marine shipping fuels.
The figure below, developed by Dr Robert Rohde at Berkeley Earth, shows a current best-estimate of the impact of each of these effects over the past 10 years based on published studies to-date. The shading indicates a warming (red) or cooling (blue) influence on global temperatures.
While each of these factors are small on their own, their combined effects may be to add around 0.1C to global temperatures in 2023.
Temperatures are tracking climate model projections
Climate models provide physics-based estimates of future warming given different assumptions about future emissions, greenhouse gas concentrations and other climate-influencing factors.
The figure below shows the range of individual models forecasts featured in the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report – known collectively as the CMIP5 models – between 1970 and 2030, with grey shading and the average projection across all the models shown in black. Individual observational temperature records are represented by coloured lines.
In these models, estimates of temperatures prior to 2005 are a “hindcast” using known past climate influences, while temperatures projected after 2005 are a “forecast” based on an estimate of how things might change.
Twelve-month average global average surface temperatures from CMIP5 models and observations between 1970 and 2023. Models use RCP4.5 forcings after 2005. They include sea surface temperatures over oceans and surface air temperatures over land to match what is measured by observations. Anomalies plotted with respect to a 1981-2010 baseline. Chart by Carbon Brief.
While global temperatures were running below the pace of warming projected by climate models between 2005 and 2014, the past decade has been closer to the model average.
Currently the latter part of 2022 and early 2023 is suppressing the 12-month average compared to the most recent months, but observations are expected to be well above the model average by mid-2024.
Record high ocean heat content
Human-emitted greenhouse gases trap extra heat in the atmosphere. While some of this warms the Earth’s surface, the vast majority – around 93% – goes into the oceans. About two-thirds of this accumulates in the top 700 metres, but some also ends up in the deep oceans.
The figure below shows annual OHC estimates between 1950 and present for both the upper 700 metres (light blue shading) and 700-2000 metre (dark blue) depths of the ocean.
Monthly global ocean heat content (in zettajoules – billion trillion joules, or 10^21 joules) for the 0-700 metre and 700-2000 metre layers. Data from IAP. Chart by Carbon Brief.
In many ways, OHC represents a much better measure of climate change than global average surface temperatures. It is where most of the extra heat ends up and is much less variable on a year-to-year basis than surface temperatures.
Just about every year since 1991 has set a new OHC record, showing that heat has continued to accumulate in the Earth system as concentrations of atmospheric greenhouse gases have increased.
Over the last 12 months, ocean heat content has increased by 42 zettajoules, or around 72 times as much as the total energy produced by all human activities on Earth last year.
Record low Antarctic sea ice extent
Highly accurate observations of Arctic and Antarctic sea ice have been available since polar-observing satellites became available in the late 1970s.
The figure below shows both Arctic (red) and Antarctic (blue) sea ice extent in 2023, the historical range in the record between 1979 and 2010 (shaded areas) and the record lows (dotted black line).

The bold lines show daily 2023 values, the shaded area indicates the two standard deviation range in historical values between 1979 and 2010. The dotted black lines show the record lows for each pole. Chart by Carbon Brief.
Arctic sea ice extent during the first three quarters of 2023 has been at the low end of the historical 1979-2010 range, but has not seen any record daily lows except for a few days in February and April.
The annual minimum sea ice extent in September was the sixth lowest on record, though still well above the record low set in 2012.

Antarctic sea ice, on the other hand, has set new all-time low records for most of 2023, set a new all-time low extent in February 2023, and has been far below any prior levels ever since mid May.

State of the climate: Global temperatures throughout mid-2023 shatter records
The European Commission has rejected requests by green groups to review the status of 16 controversial projects it has designated as “strategic” to shore up the bloc’s supply of critical minerals needed for the energy transition, despite environmental concerns.
Campaigners accused the European Union’s executive arm of being more interested in labelling projects as “strategic” to accelerate their development than ensuring they meet its environmental standards.
Legal experts told Climate Home News that despite the EU’s rhetoric on developing sustainable mining standards, it will be very difficult for local communities and NGOs to use the judicial system to enforce compliance with environmental safeguards.
Earlier this year, the European Commission labelled 47 mineral extraction, processing and recycling projects within EU member states as “strategic“, granting them preferential treatment for gaining permits and easier access to EU funding.

COP30 draft text includes energy transition minerals in UN climate first
A draft negotiating text on defining principles for a just transition to clean energy systems recognises the social and environmental risks associated with mining critical minerals
Spanning from the north of Sweden to Portugal and southern Spain, these projects are due to help the EU reach targets for sourcing more of the minerals it needs for clean energy and digital technologies within its own borders in an environmentally friendly way, while reducing its dependence on imports from China.
However, NGOs and local communities have accused the European Commission of a lack of transparency and of failing to engage civil society over the selection of these projects, most of which are in the early stages of development and are yet to obtain the necessary permits or conduct detailed environmental impact assessments.
Civil society groups challenged the decision to include around a third of projects on the strategic list, arguing that the commission had not properly assessed their sustainability. They also cited risks of social and environmental harm and human rights violations.
EU: Environmental compliance lies with member states
In total, 11 requests for review covering 16 of the projects planned within the EU were filed under the Aarhus Regulation, which gives NGOs the right to ask the European Commission to review administrative decisions if they are considered to violate the bloc’s environmental law.
In a single response shared with green groups this week, and seen by Climate Home News, the commission found that the requests to review the projects’ status were “unfounded”.
“A thorough assessment confirmed that all points raised by the NGOs had already been properly addressed during the selection process. All the projects concerned therefore retain their status as strategic projects,” a European Commission spokesperson told Climate Home News. They did not respond to detailed questions about their assessment.
Under the EU’s Critical Raw Materials Act, which was adopted last year, the commission can designate mineral projects as strategic if they meet a shortlist of criteria, including that the project “would be implemented sustainably” and monitor, prevent and minimise environmental and adverse social impacts.
The strategic status can be revoked if projects no longer meet the criteria.
However, the commission said it was not its job to carry out a full and detailed assessment of whether the projects fully comply with EU environmental laws, adding that it is only required to make an “overall assessment”.
Rather, it argued, member states have the responsibility to ensure the projects fully comply with EU environmental standards including impacts on biodiversity and ground water as well as waste management.
The commission also refused to examine the social impacts of the projects on community livelihoods, health and human rights – which could arise from environmental degradation – arguing that this was outside the scope of the review mechanism under the Aarhus Regulation.
Campaigners have strongly criticised the response.
“Cosmetic”sustainability criteria
Ilze Tralmaka, a lawyer at Client Earth, told Climate Home News the commission’s decision showed that the designation of mineral projects as “strategic” doesn’t make them safe or sustainable, despite creating a legal presumption that they serve the public interest and protect public health and safety.
“While on paper, there is mention of sustainability, in practice, it’s almost cosmetic,” she said. “It seems the environmental standards are just briefly looked at and that the policy of declaring these projects as strategic is more important than real engagement with the sustainability criteria.”
Client Earth argues that while securing supplies of minerals for the energy transition is a legitimate goal, the status of strategic project is being “misused” to fast-track questionable mining projects.
Tralmaka said the European Commission should engage where there are “unanswered questions, or if there is credible information about these projects being potentially unsafe”.
Client Earth was part of a group of NGOs that challenged the decision to designate the Barroso lithium project in Portugal as a strategic project.
“Textbook example of how not to do a green transition”
London-listed Savannah Resources is planning to dig four open pit mines in the northern Barroso region to extract lithium from Europe’s largest known deposit. The company says it will extract enough lithium every year to produce around half a million batteries for electric vehicles.
However, local groups have staunchly opposed the mining project, citing concerns over waste management and water use as well as the impact of the mine on traditional agriculture in the area.
Earlier this year, a UN committee found that Portugal had failed to respect citizens’ rights to information and public participation in the case of the Barroso project. Portuguese authorities denied the breach.
Efforts to green lithium extraction face scrutiny over water use
The commission said it was satisfied with the project’s overall sustainability credentials and that campaign groups should take a case to their national court if they are concerned about the legality of any project.
“This decision shows that the EU is willing to trade rural lives and irreplaceable landscapes for a political headline,” said Nik Völker of MiningWatch Portugal. “The truth is, the Mina do Barroso mine offers minimal benefits and enormous risks: a textbook example of how not to do a green transition.”
Savannah Resources did not respond to a request for comment.
“Murky” standards make legal challenge hard
Simon Simanovski, a business and human rights attorney with German law firm Günther Rechtsanwälte, has advised dozens of communities affected by projects designated as “strategic” under the EU’s Critical Raw Materials Act over the past year.
For him, the commission’s response creates a disconnect between its role as a decision-making body and the responsibility for enforcing the bloc’s environmental laws, by pushing it to member states. That, he said, creates “murky standards”.
This, he added, will make it “really difficult” to challenge inadequate environmental safeguards through the courts. “It means that there is no effective judicial protection… and that the projects will happen,” he told Climate Home News.
However, Simanovski still expects some campaign groups to try filing a case before the general court of the European Court of Justice to challenge the European Commission’s response and ask it to review its assessment of the projects.
Simanovski represents communities in Serbia that are also challenging the “strategic” designation of the Jadar lithium mine – one of an additional 13 “strategic projects” located outside EU countries – which has seen massive local opposition.
The commission is expected to respond to requests to review those external strategic projects in January.

DeBriefed 28 November 2025: COP30’s ‘frustrating’ end; Asia floods; UK ‘emergency’ climate event
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
‘Lukewarm’ end to COP30
BYE BELÉM: The COP30 climate talks in Belém ended last weekend with countries agreeing on a goal to “triple” adaptation finance by 2035 and efforts to “strengthen” climate plans, Climate Home News reported. The final deal “fell short on the global transition away from oil, gas and coal”, the outlet said, as Brazil announced that it would bring forward voluntary roadmaps to phase out fossil fuels and deforestation, before the next COP. It was a “frustrating end” for more than 80 countries who wanted a roadmap away from fossil fuels to be part of the formal COP agreement, BBC News said.
WHAT HAPPENED?: Carbon Brief published its in-depth analysis of all the key outcomes from COP30, spanning everything from negotiations on adaptation, just transition, gender and “Article 6” carbon trading through to a round-up of pledges on various issues. Another Carbon Brief article summed up outcomes around food, forests, land and nature. Also, Carbon Brief journalists discussed the COP in a webinar held earlier this week.
ART OF THE DEAL: The “compromise” COP30 deal – known as the “global mutirão” – “exposed deep rifts over how future climate action should be pursued”, Reuters noted. The “last-ditch” agreement was reached after fossil-fuel wording negotiations between the EU and Saudi Arabia, according to the Guardian. Meanwhile, Carbon Brief revealed the “informal” list of 84 countries said to have “opposed” the inclusion of a fossil-fuel roadmap in the mutirão decision, but analysis of the list exposed contradictions and likely errors.
UNITY, SCIENCE, SENSE: The final agreement received “lukewarm praise”, said the Associated Press. Palau ambassador Ilana Seid, who chaired the coalition of small-island nations, told the newswire: “Given the circumstances of geopolitics today, we’re actually quite pleased…The alternative is that we don’t get a decision and that would have been [worse].” UN climate chief Simon Stiell said that amid “denial, division and geopolitics”, countries “chose unity, science and economic common sense”, reported the Press Trust of India.
Around the world
- Floods and landslides killed more than 200 people in Thailand and Indonesia this week, reported Bloomberg. At least 90 people also died in recent floods in Vietnam, said Al Jazeera.
- New measures to cut energy bills and a “pay-per-mile” electric-vehicle levy were among the announcements in the UK’s budget, said Carbon Brief.
- The Group of 20 (G20) leaders signed off on a declaration “addressing the climate crisis” and other issues, reported Reuters, which had no input from the US who boycotted last week’s G20 summit in South Africa.
- Canadian prime minister Mark Carney signed a deal with the province of Alberta “centred on plans for a new heavy oil pipeline”, said the Guardian, adding that Canadian culture minister and former environment minister, Steven Guilbeault, resigned from cabinet over the deal.
- Greenpeace analysis, covered by Reuters, found that permits for new coal plants in China are “on track to fall to a four-year low” in 2025.

Captured
The key COP30 agreement – termed the “global mutirão” – contained 69 inactive verbs, which require no action from countries, compared to 32 active ones. “Recognises”, “recalls” and “acknowledges” were used far more often than more active verbs, such as “decides”, “calls” and “requests”, showed Carbon Brief analysis.
Spotlight
Nine warnings from a UK climate and nature ‘emergency’ briefing
This week, Carbon Brief’s Orla Dwyer reports from an event where experts and campaigners sounded the alarm bell on climate change and nature loss.
Naturalist and broadcaster Chris Packham urged attendees at a climate and nature “emergency briefing” in London yesterday to “listen to the science” on climate change amid a “dangerous wave of misinformation and lies”.
The “first-of-its-kind” event heard from nine experts on the links between climate change, nature loss, health, food production, economics and national security.
Event host, Prof Mike Berners-Lee from Lancaster University, called for a “World War II level of leadership” to tackle the interconnected crises.
Hundreds of people showed up, including Green Party, Labour and Liberal Democrat MPs, leader of the Greens Zack Polanski, musician Brian Eno and actress Olivia Williams.
Here is a snapshot of what the nine speakers said in their short, but stark, presentations.
Prof Kevin Anderson, professor of energy at University of Manchester
Anderson focused on the risks of a warmer world and the sliver of emissions left in the global carbon budget, noting:
“We have to eliminate fossil fuels or temperatures will just keep going up.”
He urged a “Marshall-style” plan – referencing the 1948 post-war US plan to rebuild Europe – to ramp up actions on retrofitting, public transport and electrification.
Prof Nathalie Seddon, professor of biodiversity at University of Oxford
Nature is not a “nice to have”, but rather “critical national infrastructure”, Seddon told attendees. She called for the “need to create an economy that values nature”.
Prof Paul Behrens, British Academy global professor at University of Oxford
Behrens discussed the food security risks from climate change. Impacts such as poor harvests and food price inflation are “barely acknowledge[d]” in agricultural policy, he said.
He also emphasised the “unsustainable” land use of animal agriculture, which “occupies around 85% of total agricultural land” in the UK.
Prof Tim Lenton, chair in climate change and Earth system science at Exeter University
Lenton outlined the “plenty” of evidence that parts of the Earth system are hurtling towards climate tipping points that could push them irreversibly into a new state.
He discussed the possibility of the shutdown of the Atlantic Meridional Overturning Circulation, which he said could cause -20C winters in London. He also noted positive tipping points, such as momentum that led the UK to stop burning coal for electricity last year.
Prof Hayley Fowler, professor of climate change impacts at Newcastle University
One in four properties in England could be at risk of flooding by 2050, Fowler said, and winters are getting wetter.
She discussed extreme weather risks and listed the impacts of floods in recent years in Germany, Spain and Libya, adding:
“These events are not warnings of what might happen in the future. They’re actually examples of what is happening right now.”
Angela Francis, director of policy solutions at WWF-UK
Francis factchecked several claims made against climate action, such as the high cost of achieving net-zero.
She noted that the estimated cost for the UK to achieve net-zero is about £4bn per year, which is less than 0.2% of GDP.
Lieutenant general Richard Nugee, climate and security advisor
Discussing the risks climate change poses to national security, Nugee said:
“Climate change can be thought of as a threat multiplier, making existing threats worse or more frequent and introducing new threats. Climate shocks fuel global instability.”
Tessa Khan, environmental lawyer and executive director of Uplift
Khan said the rising cost of energy in the UK is “turning into a significant political risk for the energy transition”.
She discussed the cost of fossil-fuel dependency and the fact that these fuels cost money to burn, but renewable “input[s], sun or wind [are] free forever”.
Prof Hugh Montgomery, professor of intensive care medicine at University College London
Montgomery discussed the health and economic benefits of climate actions, such as eating less meat and using more public transport, noting:
“The climate emergency is a health emergency – and it’s about time we started treating it as one.”
Watch, read, listen
WATER WORRIES: ABC News spoke to three Iranian women about the impacts of Tehran’s water crisis amid the “worst drought in 60 years”.

Revealed: Leak casts doubt on COP30’s ‘informal list’ of fossil-fuel roadmap opponents
A confused – and, at times, contradictory – story has emerged about precisely which countries and negotiating blocs were opposed to a much-discussed “roadmap” deal at COP30 on “transitioning away from fossil fuels”.
Carbon Brief has obtained a leaked copy of the 84-strong “informal list” of countries that, as a group, were characterised across multiple media reports as “blocking” the roadmap’s inclusion in the final “mutirão” deal across the second week of negotiations at the UN climate summit in Belém.
During the fraught closing hours of the summit, Carbon Brief understands that the Brazilian presidency told negotiators in a closed meeting that there was no prospect of reaching consensus on the roadmap’s inclusion, because there were “80 for and 80 against”.
However, Carbon Brief’s analysis of the list – which was drawn up informally by the presidency – shows that it contains a variety of contradictions and likely errors.
Among the issues identified by Carbon Brief is the fact that 14 countries are listed as both supporting and opposing the idea of including a fossil-fuel roadmap in the COP30 outcome.
In addition, the list of those said to have opposed a roadmap includes all 42 of the members of a negotiating group present in Belém – the least-developed countries (LDCs) – that has explicitly told Carbon Brief it did not oppose the idea.
Moreover, one particularly notable entry on the list, Turkey – which is co-president of COP31 – tells Carbon Brief that its inclusion is “wrong”.
Negotiating blocs
COP28, held in Dubai in 2023, had finalised the first “global stocktake”, which called on all countries to contribute to global efforts, including a “transition away from fossil fuels”.
Since then, negotiations on how to take this forward have faltered, including at COP29 in Baku, Azerbaijan, where countries were unable to agree to include this fossil-fuel transition as part of existing or new processes under the UN climate regime.
Ahead of the start of COP30, Brazilian president Luiz Inácio Lula da Silva made a surprise call for “roadmaps” on fossil-fuel transition and deforestation.
While this idea was not on the official agenda for COP30, it had been under development for months ahead of the summit – and it became a key point of discussion in Belém.
Ultimately, however, it did not become part of the formal COP30 outcome, with the Brazilian presidency instead launching a process to draw up roadmaps under its own initiative.
This is because the COP makes decisions by consensus. The COP30 presidency insisted that there was no prospect of consensus being reached on a fossil-fuel roadmap, telling closed-door negotiations that there were “80 for and 80 against”.
The list of countries supporting a roadmap as part of the COP30 outcome was obtained by Carbon Brief during the talks. Until now, however, the list of those opposed to the idea had not been revealed.
Carbon Brief understands that this second list was drawn up informally by the Brazilian presidency after a meeting attended by representatives of around 50 nations. It was then filled out to the final total of 84 countries, based on membership of negotiating alliances.
The bulk of the list of countries opposing a roadmap – some 39 nations – is made up of two negotiating blocs that opposed the proposal for divergent reasons (see below). Some countries within these blocs also held different positions on why – or even whether – they opposed the roadmap being included in the COP30 deal.
These blocs are the 22-strong Arab group – chaired in Belém by Saudi Arabia – and the 25 members of the “like-minded developing countries” (LMDCs), chaired by India.
For decades within the UN climate negotiations, countries have sat within at least one negotiating bloc rather than act in isolation. At COP30, the UN says there were 16 “active groups”. (Since its invasion of Ukraine, Russia has not sat within any group.)
The inclusion on the “informal list” (shown in full below) of both the LMDCs and Arab group is accurate, as confirmed by the reporting of the International Institute for Sustainable Development’s Earth Negotiations Bulletin (ENB), which is the only organisation authorised to summarise what has happened in UN negotiations that are otherwise closed to the media.
Throughout the fortnight of the talks, both the LMDCs and Arab group were consistent – at times together – in their resistance to proscriptive wording and commitments within any part of the COP30 deal around transitioning away from fossil fuels.
But the reasons provided were nuanced and varied and cannot be characterised as meaning both blocs simply did not wish to undertake the transition – in fact, all countries under the Paris Agreement had already agreed to this in Dubai two years ago at COP28.
However, further analysis by Carbon Brief of the list shows that it also – mistakenly – includes all of the members of the LDCs, bar Afghanistan and Myanmar, which were not present at the talks. In total, the LDCs represented 42 nations in Belém, ranging from Bangladesh and Benin through to Tuvalu and Tanzania.
Some of the LDC nations had publicly backed a fossil-fuel roadmap.
‘Not correct’
Manjeet Dhakal, lead adviser to the LDC chair, tells Carbon Brief that it is “not correct” that the LDCs, as a bloc, opposed a fossil-fuel roadmap during the COP30 negotiations.
He says that the group’s expectations, made public before COP, clearly identified transitioning away from fossil fuels as an “urgent action” to keep the Paris Agreement’s 1.5C goal “within reach”. He adds:
“The LDC group has never blocked a fossil-fuel roadmap. [In fact], a few LDCs, including Nepal, have supported the idea.”
Dhakal’s statement highlights a further confusing feature of the informal list – 14 countries appear on both of the lists of supporters and opposers. This is possible because many countries sit within two or more negotiating blocs at UN climate talks.
For example, Kiribati, Solomon Islands and Tuvalu are members of both the “alliance of small island states” (AOSIS) and the LDCs.
As is the case with the “informal list” of opposers, the list of supporters (which was obtained by Carbon Brief during the talks) is primarily made up of negotiating alliances.
Specifically, it includes AOSIS, the “environmental integrity group” (EIG), the “independent association of Latin America and the Caribbean” (AILAC) and the European Union (EU).
In alphabetical order, the 14 countries on both lists are: Bahrain; Bulgaria; Comoros; Cuba; Czech Republic; Guinea-Bissau; Haiti; Hungary; Kiribati; Nepal; Sierra Leone; Solomon Islands; Timor-Leste; and Tuvalu.
This obvious anomaly acts to highlight the mistaken inclusion of the LDCs on the informal list of opposers.
The list includes 37 of the 54 nations within the Africa group, which was chaired by Tanzania in Belém.
But this also appears to be a function of the mistaken inclusion of the LDCs in the list, many of which sit within both blocs.
Confusion
An overview of the talks published by the Guardian this week reported:
“Though [Brazil’s COP30 president André Corrêa do Lago] told the Guardian [on 19 November] that the divide over the [roadmap] issue could be bridged, [he] kept insisting 80 countries were against the plan, though these figures were never substantiated. One negotiator told the Guardian: ‘We don’t understand where that number comes from.’
“A clue came when Richard Muyungi, the Tanzanian climate envoy who chairs the African group, told a closed meeting that all its 54 members aligned with the 22-member Arab Group on the issue. But several African countries told the Guardian this was not true and that they supported the phaseout – and Tanzania has a deal with Saudi Arabia to exploit its gas reserves.”
Adding to the confusion, the Guardian also said two of the most powerful members of the LMDCs were not opposed to a roadmap, reporting: “China, having demurred on the issue, indicated it would not stand in the way [of a roadmap]; India also did not object.”
Writing for Climate Home News, ActionAid USA’s Brandon Wu said:
“Between rich country intransigence and undemocratic processes, it’s understandable – and justifiable – that many developing countries, including most of the Africa group, are uncomfortable with the fossil-fuel roadmap being pushed for at COP30. It doesn’t mean they are all ‘blockers’ or want the world to burn, and characterising them as such is irresponsible.
“The core package of just transition, public finance – including for adaptation and loss and damage – and phasing out fossil fuels and deforestation is exactly that: a package. The latter simply will not happen, politically or practically, without the former.”
Carbon Brief understands that Nigeria was a vocal opponent of the roadmap’s inclusion in the mutirão deal during the final hours of the closed-door negotiations, but that does not equate to it opposing a transition away from fossil fuels. This is substantiated by the ENB summary:
“During the…closing plenary…Nigeria stressed that the transition away from fossil fuels should be conducted in a nationally determined way, respecting [common, but differentiated responsibilities and respective capabilities].”
The “informal list” of opposers also includes three EU members – Bulgaria, the Czech Republic and Hungary.
The EU – led politically at the talks by climate commissioner Wopke Hoekstra, but formally chaired by Denmark – was reportedly at the heart of efforts to land a deal that explicitly included a “roadmap” for transitioning away from fossil fuels.
Carbon Brief understands that, as part of the “informal intelligence gathering” used to compile the list, pre-existing positions on climate actions by nations were factored in rather than only counting positions expressed at Belém. For example, Hungary and the Czech Republic were reported to have been among those resisting the last-minute “hard-fought deal” by the EU on its 2040 climate target and latest Paris Agreement climate pledge.
(Note that EU members Poland and Italy did not join the list of countries supporting a fossil-fuel roadmap at COP30.)
The remaining individual nations on the informal list either have economies that are heavily dependent on fossil-fuel production (for example, Russia and Brunei Darussalam), or are, like the US, currently led by right-leaning governments resistant to climate action (for example, Argentina).
Turkey is a notable inclusion on the list because it was agreed in Belém that it will host next year’s COP31 in Antalya, but with Australia leading the negotiation process. In contrast, Australia is on the 85-strong list of roadmap supporters.
However, a spokesperson for Turkey’s delegation in Belem has told Carbon Brief that it did not oppose the roadmap at COP30 and its inclusion on the list is “wrong”.
Media characterisations
Some media reporting of the roadmap “blockers” sought to identify the key proponents.
For example, the Sunday Times said “the ‘axis of obstruction’ – Saudi Arabia, Russia and China – blocked the Belém roadmap”.
Agence France-Presse highlighted the views of a French minister who said: “Who are the biggest blockers? We all know them. They are the oil-producing countries, of course. Russia, India, Saudi Arabia. But they are joined by many emerging countries.”
Reuters quoted Vanuatu’s climate minister alleging that “Saudi Arabia was one of those opposed”.
The Financial Times said “a final agreement [was] blocked again and again by countries led by Saudi Arabia and Russia”.
Bloomberg said the roadmap faced “stiff opposition from Arab states and Russia”.
Media coverage in India and China has pushed back at the widespread portrayals of what many other outlets had described as the “blockers” of a fossil-fuel roadmap.
The Indian Express reported:
“India said it was not opposed to the mention of a fossil-fuel phaseout plan in the package, but it must be ensured that countries are not called to adhere to a uniform pathway for it.”
Separately, speaking on behalf of the LMDCs during the closing plenary at COP30, India had said: “Adaptation is a priority. Our regime is not mitigation centric.”
China Daily, a state-run newspaper that often reflects the government’s official policy positions, published a comment article this week stating:
“Over 80 countries insisted that the final deal must include a concrete plan to act on the previous commitment to move beyond coal, oil, and natural gas adopted at COP28…But many delegates from the global south disagreed, citing concerns about likely sudden economic contraction and heightened social instability. The summit thus ended without any agreement on this roadmap.
“Now that the conference is over, and emotions are no longer running high, all parties should look objectively at the potential solution proposed by China, which some international media outlets wrongly painted as an opponent to the roadmap.
“Addressing an event on the sidelines of the summit, Xia Yingxian, deputy head of China’s delegation to COP30, said the narrative on transitioning away from fossil fuels would find greater acceptance if it were framed differently, focusing more on the adoption of renewable energy sources.”
Speaking to Carbon Brief at COP30, Dr Osama Faqeeha, Saudi Arabia’s deputy environment minister, refused to be drawn on whether a fossil-fuel roadmap was a red line for his nation, but said:
“I think the issue is the emissions, it’s not the fuel. And our position is that we have to cut emissions regardless.”
Neither the Arab group nor the LMDCs responded to Carbon Brief’s invitation to comment on their inclusion on the list.
The Brazilian COP30 presidency did not respond at the time of publication.
While the fossil-fuel roadmap was not part of the formal COP30 outcome, the Brazilian presidency announced in the closing plenary that it would take the idea forward under its own initiative, drawing on an international conference hosted in Colombia next year.
Corrêa do Lago told the closing plenary:
“We know some of you had greater ambitions for some of the issues at hand…As president Lula said at the opening of this COP, we need roadmaps so that humanity, in a just and planned manner, can overcome its dependence on fossil fuels, halt and reverse deforestation and mobilise resources for these purposes.
“I, as president of COP30, will therefore create two roadmaps, one on halting and reverting deforestation, another to transitioning away from fossil fuels in a just, orderly and equitable manner. They will be led by science and they will be inclusive with the spirit of the mutirão.
“We will convene high level dialogues, gathering key international organisations, governments from both producing and consuming countries, industry workers, scholars, civil society and will report back to the COP. We will also benefit from the first international conference for the phase-out of fossil fuels, scheduled to take place in April in Colombia.”
