A victory for Donald Trump in November’s presidential election could lead to an additional 4bn tonnes of US emissions by 2030 compared with Joe Biden’s plans, Carbon Brief analysis reveals.
This extra 4bn tonnes of carbon dioxide equivalent (GtCO2e) by 2030 would cause global climate damages worth more than $900bn, based on the latest US government valuations.
For context, 4GtCO2e is equivalent to the combined annual emissions of the EU and Japan, or the combined annual total of the world’s 140 lowest-emitting countries.
Put another way, the extra 4GtCO2e from a second Trump term would negate – twice over – all of the savings from deploying wind, solar and other clean technologies around the world over the past five years.
If Trump secures a second term, the US would also very likely miss its global climate pledge by a wide margin, with emissions only falling to 28% below 2005 levels by 2030. The US’s current target under the Paris Agreement is to achieve a 50-52% reduction by 2030.
Carbon Brief’s analysis is based on an aggregation of modelling by various US research groups. It highlights the significant impact of the Biden administration’s climate policies. This includes the Inflation Reduction Act – which Trump has pledged to reverse – along with several other policies.
The findings are subject to uncertainty around economic growth, fuel and technology prices, the market response to incentives and the extent to which Trump is able to roll back Biden’s policies.
The analysis might overstate the impact Trump could have on US emissions, if some of Biden’s policies prove hard to unpick – or if subnational climate action accelerates.
Equally, it might understate Trump’s impact. For example, his pledge to “drill, baby, drill” is not included within the analysis and would likely raise US and global emissions further through the increased extraction and burning of oil, gas and coal.
Also not included are the potential for Biden to add new climate policies if he wins a second term, nor the risk that some of his policies will be weakened, delayed or hit by legal challenges.
Regardless of the precise impact, a second Trump term that successfully dismantles Biden’s climate legacy would likely end any global hopes of keeping global warming below 1.5C.

The ‘Trump effect’ on US emissions
US greenhouse gas emissions have been falling steadily since 2005, due to a combination of economic shifts, greater efficiency, the growth of renewables and a shift from coal to gas power.
Since taking office in early 2021, Biden has pledged under the Paris Agreement to accelerate that trend by cutting US emissions to 50-52% below 2005 levels in 2030 and to net-zero in 2050.
He has implemented a long list of policies – most notably the 2022 Inflation Reduction Act – to keep those targets within reach. (See: How the Biden administration is tackling warming.)
In the “Biden” scenario in the figure below (blue line), all federal climate policies currently in place or in the process of being finalised are assumed to continue. The scenario does not include any new climate policies that might be adopted after November’s election.
The administration’s current climate policies are expected to cut US emissions significantly, bringing the country close to meeting its 2030 target range. Nevertheless, a gap remains between projected emissions and those needed to meet the 2030 and 2050 targets (green).
The “Trump” scenario (red line) assumes the IRA and other key Biden administration climate policies are rolled back. It does not include further measures that Trump could take to boost fossil fuels or undermine the progress of clean energy. (See: What a second-term Trump might do.)
For both projections, the shaded area shows the range of results from six different models, with varying assumptions on economic growth, fuel costs and the price of low-carbon technologies.
In total, the analysis suggests that US greenhouse gas emissions would fall to 28% below 2005 levels by 2030 if Trump secures a second term and rolls back Biden’s policies – far short of the 50-52% target. If Biden is reelected, emissions would fall to around 43% below 2005 levels.
In the Trump scenario, annual US greenhouse gas emissions would be around 1GtCO2e higher in 2030 than under Biden, resulting in a cumulative addition of around 4GtCO2e by that year.
Based on the recently updated central estimate of the social cost of carbon from the US Environmental Protection Agency (US EPA) – which stands at some $230 per tonne of CO2 in 2030 – those 4GtCO2e of extra emissions would cause global climate damages worth more $900bn.
To put the additional emissions in context, EU greenhouse gas emissions currently stand at around 3GtCO2e per year, while Japan’s are another 1GtCO2e. If the EU meets its climate goals, then its emissions would fall to 2GtCO2e in 2030 and to below 1GtCO2e in 2040.
Only eight of the world’s nearly 200 countries have emissions that exceed 1GtCO2e per year – and 4GtCO2e is more than the combined yearly total from the 140 lowest-emitting nations.
Expressed another way, the extra 4GtCO2e would be equivalent to double all of the emissions savings secured globally, over the past five years, by deploying wind, solar, electric vehicles, nuclear and heat pumps.
Carbon Brief’s analysis highlights several key points.
First, that Biden’s climate goals for the US in 2030 and 2050 will not be met, without further policy measures after the next election.
This could include additional state-level action, which could yield an additional 4 percentage points of emissions savings by 2030. Added to the “Biden” pathway, this would take US emissions to 47% below 2005 levels – closer to, but still not in line with the 2030 pledge.
Second, despite this policy gap, Biden’s current climate policies go a significant way towards meeting the 2030 target and could be added to in the future.
Third, if Trump is able to remove all of Biden’s key climate policies, then the US is all but guaranteed to miss its targets by a wide margin.
Given the scale of US emissions and its influence on the world, this makes the election crucial to hopes of limiting warming to 1.5C. (See: The global climate implications of the US election.)
Finally, there is policy uncertainty around which policies will be finalised, how strong any final rules will be, what legal challenges they may face and how easy they prove to roll back.
There is also uncertainty – illustrated by the ranges in the chart – around the impact of Biden’s policies, the response of households, business and industry to those measures, and the rate of economic growth, as well as over future prices for fossil fuels and low-carbon technologies.
These uncertainties are partly – but not entirely – captured by the six models underlying the analysis, which have different model structures and input assumptions.
How the Biden administration is tackling warming
In 2015, the then-president Barack Obama pledged a 26-28% reduction in US emissions below 2005 levels by 2025 as an intended “nationally determined contribution” (iNDC) to the Paris Agreement.
On taking office in 2017, the climate-sceptic president Trump then pulled the US out of the Paris Agreement, attracting global opprobrium. He then rolled back or replaced Obama-era climate policies, including the Clean Power Plan, while attempting – unsuccessfully – to prop up coal.
Trump’s successor as president, Joe Biden, campaigned in 2020 on a platform of a “clean energy revolution”. On gaining office in 2021, he immediately rejoined the Paris Agreement and then issued a more ambitious pledge to cut US emissions to 50-52% below 2005 levels by 2030.
Biden also pledged to decarbonise the electricity grid by 2035 and joined roughly 150 other countries in committing the US to reaching net-zero emissions by 2050 – the global benchmark, if the world is to keep warming below 1.5C.
In order to keep these targets within reach, the Biden administration has ushered in a series of climate policies. Most notable is the 2022 IRA, unexpectedly passed by Congress after a 51-50 Senate vote, with the tie broken by the vice president Kamala Harris.
This has been called the largest package of domestic climate measures in US history. It offers incentives covering a broad swathe of the economy from low-carbon manufacturing to clean energy, electric vehicles, “climate-smart” agriculture and low-carbon hydrogen.
The IRA accounts for the most significant part of the emissions reductions expected as a result of Biden’s climate policies to date and shown by the blue line in the figure above.
It includes grants, loans and tax credits initially estimated to be worth $369bn. However, most of the tax credits are not capped, meaning the overall cost and impact on emissions is uncertain.
In general, cost estimates have risen since its passing, as investments triggered by the bill’s incentives have rolled in, with some now putting its ultimate cost above $1tn.
However, a recent analysis of progress since the bill passed in 2021 shows that while electric vehicle sales are running at the top end of what was expected in earlier modelling of the IRA’s impact, the deployment of clean electricity – in particular, wind power – is falling slightly behind.
(Another recent study looks at the behavioural challenges that could affect the success or failure of the IRA, including as a result of political polarisation. Separately, gas power expansion plans from several major US utilities also pose a challenge to the IRA.)
Other Biden administration initiatives with important implications for US emissions include the 2021 Infrastructure Investment and Jobs Act, loans for nuclear power plants and new standards on appliance efficiency issued by the Department of Energy.
Meanwhile, the US Environmental Protection Agency (US EPA) has finalised rules on methane emissions from oil and gas facilities. It has also proposed – but not yet finalised – rules on vehicle fuel standards, power plant greenhouse gas standards and power plant air pollution.
The administration is now rushing to finalise these rules within the next couple of months, so that they could not be overturned easily after the election using the Congressional Review Act.
The administration is reportedly planning to weaken its proposed vehicle fuel standards. The final version would retain the original aim of having two-thirds of new sales be all-electric by 2032, but would ease the trajectory to reaching that target, according to the New York Times. This would reduce the emissions-cutting impact, relative to what is assumed in the “Biden” scenario.
Separately, the administration is reported to be exempting existing gas-fired units from its proposed power plant emissions rules, focusing for now on existing coal and future gas-fired units. The New York Times quotes EPA administrator Michael Regan saying this will “achieve greater emissions reductions”, but the timescales could also affect the scenario projection.
Meanwhile, Biden has also overseen a rare Senate approval of an international climate treaty, when it ratified the Kigali Amendment on tackling climate-warming hydrofluorocarbons in 2022, with the US EPA issuing related rules the following year.
In addition, Biden’s time in office has seen further state-level action on emissions. This includes California’s clean car standards, as strengthened in 2022 and adopted by six other states.
What a second-term Trump might do
For his part, former president and Republican front-runner Donald Trump has made no secret of his desire to roll back his predecessor’s climate policies, just as he did during his first term.
For example, in 2018, the Trump administration lifted Obama-era rules on toxic air pollution from electricity generating and industrial sites – with Biden now moving to reverse the reversal.
Similarly, in 2020, his administration rolled back an Obama-era EPA rule on methane emissions from the oil and gas industry. The Biden administration’s methane rule could face a similar fate under a second Trump term.
Trump also has form when it comes to energy efficiency regulations, which he rolled back in 2020.
In November 2023, the Financial Times reported that Trump was “planning to gut” the IRA, increase investment in fossil fuels and roll back regulations to encourage electric vehicles. The newspaper added that Trump had called the IRA the “biggest tax hike in history”.
It quoted Carla Sands, an adviser to Trump, as saying:
“On the first day of a second Trump administration, the president has committed to rolling back every single one of Joe Biden’s job-killing, industry-killing regulations.”
Indeed, Republicans in the US House of Representatives have already made multiple attempts to repeal parts of the IRA. While some analysts think a full repeal of the act is unlikely, it is clear that a second-term Trump could – as Politico put it – ”hobble the climate law”.
A February 2024 commentary from investment firm Trium Capital argues that the impact on IRA will depend not only on whether Trump wins victory in November, but also on whether the Republicans retain control of the House and gain a Senate majority.
Even if the Republicans win all three races, the commentary suggests that some parts of IRA might survive beyond the election. It says that consumer incentives for electric vehicles and home heating are “most at risk”, whereas tax credits for clean energy might only be modified.
Equally, MIT Technology Review says that clean energy and EV tax credits both “appear especially vulnerable, climate policy experts say”. The publication adds:
“Moreover, Trump’s wide-ranging pledges to weaken international institutions, inflame global trade wars, and throw open the nation’s resources to fossil-fuel extraction could have compounding effects on any changes to the IRA, potentially undermining economic growth, the broader investment climate, and prospects for emerging green industries.”
Meanwhile, Trump has also criticised Biden’s infrastructure act and previously revoked California’s ability to set tougher car emissions standards, which are also adopted by other states.
In 2022, the California “waiver” was reinstated by Biden, who also opposed a 2023 Republican bill designed to remove California’s right to regulate. Yet the waiver is now embroiled in legal action brought by Republican states, expected to end up in the Supreme Court.
If he emerges victorious in November, Trump would also “plan to destroy the EPA”, according to a Guardian article published earlier this month. It reported:
“Donald Trump and his advisers have made campaign promises to toss crucial environmental regulations and boost the planet-heating fossil fuel sector. Those plans include systematically dismantling the Environmental Protection Agency (EPA), the federal body with the most power to take on the climate emergency and environmental justice, an array of Trump advisers and allies said.”
The paper cites Project 2025, described as “a presidential agenda put forth by the Heritage Foundation and other conservative organisations”. It also quotes Mandy Gunasekara, Trump’s EPA chief of staff and a contributor to the Project 2025 agenda.
After Trump was elected for the first time, many scientists, politicians and campaigners argued that his presidency would only have a relatively short-term effect on emissions and climate goals.
Many of his first-term efforts to rollback climate rules and boost fossil fuels ended in failure.
While some modelling suggested that his first presidency would delay hitting global emissions targets by a decade, Carbon Brief analysis found that US states and cities might be able to take sufficient steps to meet the country’s then-current climate goal without federal action.
However, another recent Guardian article says that a second-term Trump would be “even more extreme for the environment than his first, according to interviews with multiple Trump allies and advisers”. It adds:
“In contrast to a sometimes chaotic first White House term, they outlined a far more methodical second presidency: driving forward fossil fuel production, sidelining mainstream climate scientists and overturning rules that curb planet-heating emissions.”
Carbon Brief’s “Trump” scenario does not include additional fossil fuel emissions as a result of policies supporting coal, oil and gas production or use, as the success or otherwise of any such efforts are highly uncertain.
In addition, higher US fossil fuel production would not all be consumed domestically and would not increase global demand on a one-for-one basis.
While it would be likely to raise demand and emissions, both domestically and internationally, the precise impact would depend on the response of markets and overseas policymakers.
The global climate implications of the US election
If Biden – or another Democrat – wins the election in November and if his party regains control over the House and Senate, then they could push to implement new climate policies in 2025.
There is a clear need for further policy, if US climate goals are to be met. Moreover, the expiration of a large number of tax cuts at the end of 2025 could present an opportunity to deploy carbon pricing in support of raising revenues – and cutting emissions – according to a recent study.
It suggests that a price on emissions, described as a “carbon fee”, could significantly boost US chances of hitting its 2030 target, even if paired with a partial repeal of the IRA.
(Note that the “Repeal IRA; no new emissions rules” scenario in this study is similar to the “Trump” scenario in Carbon Brief’s analysis. However, the model used in the study finds a relatively weak 2030 emissions impact of the IRA compared with most of the five others, with which it is aggregated by Carbon Brief.)
An additional point of leverage is the EU’s carbon border adjustment mechanism (CBAM), which will put a carbon price on US exports unless they face an equivalent price domestically, according to Democratic senator Sheldon Whitehouse, speaking at a launch event for the study:
“The 2025 opportunity when the Trump tax cuts collapse [creates] huge room for negotiation. Then you’ve got the CBAM happening in Europe that puts enormous pressure to get a price of carbon, if you want to avoid being tariffed at the EU and UK level.”
Whether a second-term Biden administration would attempt to put a price on carbon or not, it would be likely to push forward new policies in pursuit of US climate targets.
In contrast, a victory for Donald Trump could be expected, at a minimum, to result in full or partial repeal of the IRA and rollbacks of Biden’s climate rules, including power plants, cars and methane.
This is reflected in Carbon Brief’s “Trump” scenario, which would add a cumulative 4GtCO2e to US emissions by 2030, as shown in the figure below.
Moreover, assuming no further policy changes, this cumulative total would continue to climb beyond 2030, reaching 15GtCO2e by 2040 and a huge 27GtCO2e by 2050.
The increases in cumulative emissions under the “Trump” scenario are so large that they would imperil not only the US climate targets, but also global climate goals. (Under the 22nd amendment of the US constitution, Trump would not be allowed to run for a third term.)
In 2022, the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report (AR6) said that it would be “impossible” to stay below 1.5C without strengthening current pledges:
“[F]ollowing current NDCs until 2030…[would make] it impossible to limit warming to 1.5C with no or limited overshoot and strongly increas[e] the challenge to likely limit warming to 2C.”
The corollary of this is that if the US – the world’s second-largest emitter – misses its 2030 target by a wide margin, then it would be likely to end any hope of keeping global warming below 1.5C.
How the analysis was carried out
The two scenarios set out in this analysis are based on an aggregation of modelling published by Bistline et al. (2023) and the Rhodium Group (2023).
The first study was explained by the authors in a Carbon Brief guest post. It compares the impact of the IRA using results from 11 separate models, some of which only cover the power sector. Carbon Brief’s analysis uses results from the six models that cover the entire US economy.
The “Trump” scenario is based on the “reference” pathway in this study, corresponding to the average of the six models. The only modification is that the Trump scenario is set to match the Biden scenario below until 2024.
The “Biden” scenario is based on the average IRA pathway from this study, extended using modelling from the Rhodium Group to include the impact of further Biden administration policies.
Carbon Brief’s analysis uses the “mid-emissions” pathway from the Rhodium study’s “federal-only” scenario, which includes the impact of vehicle fuel standards, power plant greenhouse gas and pollutant emissions rules, and energy efficiency regulations.
This additional Rhodium Group modelling is based on draft rules which have not yet been finalised and are subject to change, as well as to potential legal challenge, as discussed above.
The uncertainty shown for the “Trump” and “Biden” scenarios corresponds to the range in the six economy-wide models from Bistline et al. (2023).
Carbon Brief’s analysis does not include any additional post-2025 climate policies that could be adopted by a second Biden administration. Nor does it include the potential impact of pro-fossil fuel policies that could be introduced by a second Trump administration.
Finally, it also does not include additional subnational climate policies that could be introduced, nor does it consider the risk that current or future state action could be hit by federal or legal challenge.
Historical US greenhouse gas emissions are taken from the US EPA inventory through to 2021. Figures for 2022 and 2023 are based on estimated annual changes from the Rhodium Group.

Analysis: Trump election win could add 4bn tonnes to US emissions by 2030
Antarctic sea ice has recorded its third-smallest winter peak extent since satellite records began 48 years ago, new data reveals.
Provisional data from the US National Snow and Ice Data Center (NSIDC) shows that Antarctic sea ice hit its annual winter peak on 14 September, with an extent of 17.59m square kilometres (km2).
The organisation notes that the data is still preliminary, adding that “large fluctuations in extent are typical of Antarctic sea ice near the seasonal maximum”.
One expert tells Carbon Brief that it is “concerning to see these low values persisting”, but says that scientists need more time to determine whether this represents a “structural shift” in Antarctic sea ice extent.
Meanwhile, at the Earth’s other pole, Arctic sea ice reached its annual minimum on 12 September, ranking as the joint-10th lowest in the satellite record.
The NSIDC notes that the last 20 years have seen the lowest 20 Arctic sea ice extents in the satellite record.
Antarctic peak
Dr Lettie Roach, a polar climate scientist at the Alfred Wegener Institute in Germany, tells Carbon Brief that this year’s Antarctic sea ice maximum was “well below average for the season”. She warns that, “after several decades of stable or increasing winter Antarctic sea ice conditions, it is concerning to see these low values persisting”.
She adds:
“Compared with the Arctic, it’s less clear how recent changes in Antarctic sea ice are attributable to human-caused warming vs natural variability. We need more years of observations to better understand whether this is truly a structural shift.”
Dr Clare Eayrs, a postdoctoral researcher at the Korea Polar Research Institute (KOPRI), tells Carbon Brief that, since recording a “near-average February minimum” extent, Antarctic sea ice has “returned to unusually low winter coverage”.
She notes that Antarctic sea ice extent in July and August this year were the fifth and fourth lowest on record, respectively, adding that “all five of the lowest July extents have occurred since 2022 and all four of the lowest August extents since 2023”.
The chart below shows Antarctic sea ice extent in 2025 (dark blue) and 2026 (red) so far. For comparison, the chart shows decadal averages (dotted lines) as well as 2023 (mid blue), the year of the smallest winter sea-ice maximum on record.
Eayrs tells Carbon Brief that the regional pattern of Antarctic sea ice cover “changed substantially during the growth season”.
For example, she says that “in April, the Bellingshausen Sea remained almost entirely ice-free, while the neighbouring Amundsen Sea had more ice than usual”.
However, by late August, changes in atmospheric pressure and wind meant that “the Bellingshausen deficit had largely recovered, while ice was unusually scarce in the Amundsen Sea and across much of East Antarctica”.
Arctic minimum
Meanwhile, the Arctic recorded its minimum summer sea ice extent on 12 September. At 4.60m km2, this year ties with 2025, 2010 and 2008 as the 10th-lowest sea ice extent on record.
The chart below shows Arctic sea ice extent in 2025 (dark blue) and 2026 (red) so far. For comparison, the chart shows decadal averages (dotted lines) as well as 2012 (mid blue), the year of the smallest summer sea-ice minimum on record.
Roach tells Carbon Brief that although this minimum is not “record setting”, it is still “lower than any sea ice minimum before 2007”. She adds:
“Human-caused climate change has reduced Arctic sea ice cover and thickness, so the region is fundamentally different compared to a few decades ago.”
Scientists have been tracking Arctic sea ice thickness using a reanalysis produced called the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) since 1979.
In March 2026, the National Oceanographic and Atmospheric Administration (NOAA) terminated a global dataset of air pressure that scientists relied upon to produce PIOMAS, forcing both datasets to stop publishing updates.
The PIOMAS website says it will take “considerable effort and time” to find alternative data to use in their reanalysis. It adds that “we don’t yet have a good sense if that’s possible with available funds and if so, when we will be able to resume production of a new PIOMAS timeseries”.
Roach also notes that August saw record-breaking heat sweep across much of the world, explaining that high temperatures “extended into Arctic coastal regions, close to regions with substantial sea ice loss – particularly the Barents-Kara and East Siberian seas”.
Dr Zack Labe, a scientist at Climate Central, tells Carbon Brief that the absence of a new record does not mean that ice cover is becoming more “resilient”. He says:
“Local weather patterns across the Arctic play a really important role in year-to-year sea-ice extent, even as the long-term trend is clearly downward.”
Labe tells Carbon Brief that weather in the Arctic this summer was “influenced mainly by lower pressure toward the central Arctic, which brought cloudier and cooler conditions that limited surface melt and delayed the start of the melt season”.
He explains that this “was most obvious across parts of the Beaufort and Chukchi seas, where the melt season didn’t really kick off until after early July, which was more than two weeks later than normal”.
In contrast, he says, the Atlantic side of the Arctic “had a much more extreme summer”, with sea ice in the Barents Sea recording its “earliest melt-out on record”.
This was partly due to “unusually warm air and ocean temperatures”, Labe says. He notes, for example, that parts of western Siberia saw unusually persistent temperatures more than 5C above the 1981-2010 average for much of the summer, which extended out over the Kara Sea and contributed to substantial ice melt in this area”.
Labe tells Carbon Brief that, going forward, scientists need “more data and observations of other sea-ice metrics, like ice thickness, which may give us better insight into the overall condition of the ice pack, especially during years like 2026 when it is very fragmented”.
(In March 2026, Arctic sea ice reached its peak extent for this winter, clocking in as the joint-smallest in a satellite record going back almost half a century.)

‘Concerning’ low sea ice persists as Antarctic hits third-lowest winter peak
Participants at COP31 in Antalya will have a “duty” not to interfere in Türkiye’s internal affairs under the country’s hosting deal with the UN, reviving a clause dropped for last year’s climate summit in Brazil that human rights groups warn could put activists at risk.
Türkiye has faced growing criticism from human rights groups over the jailing of opposition figures, journalists and activists and imposed a blanket protest ban around July’s summit of the NATO military alliance in Ankara.
The contested provision is included in the binding agreement between the UN climate secretariat and the Turkish government that sets out responsibilities over logistical arrangements and details participants’ rights and obligations.
The document, signed in June but only made public on Wednesday, gives accredited COP31 attendees immunity from legal action over what they say, write or do in connection with the conference. Climate Home News understands that this safeguard can be applied to what takes place both inside and, in certain circumstances, outside of the UN-controlled COP “Blue Zone”. For the first time, this protection explicitly continues after the summit ends.
But participants enjoying these “privileges and immunities” also have a duty to respect Türkiye’s laws and regulations and not to interfere in its internal affairs, the agreement states. Rights groups fear its wide-ranging formulation could be used to discourage criticism of the host government.
Climate Home News understands that whether an action is covered by the immunity or infringes on the host’s internal affairs would be evaluated on a case-by-case basis, with close coordination between the country’s authorities and the UN climate change body.
A separate provision states that immunity shall be waived where the UN believes it would “impede the course of justice”.
‘Chilling effect’
Those same provisions featured in the host country agreements for COP28 in the United Arab Emirates and COP29 in Azerbaijan, both regarded as authoritarian regimes, before being dropped for COP30 in Brazil.
Ann Harrison, climate justice policy advisor at Amnesty International, said it is “extremely disappointing” that the COP31 agreement re-introduced clauses that could “hinder the ability of human rights defenders and civil society organisations to conduct their work safely”.
COP31 electrification pledge leaves out clean power commitment
She added the provisions could have a “wider chilling effect” on rights to freedom of expression and peaceful assembly, given concerns over the human rights situation in Türkiye, including laws that “have shrunk civic space” and their “abusive” implementation by authorities.
The UN climate change body declined to comment.
Rights groups have documented blanket protest bans, unlawful use of force by the police and prosecutions of journalists, human rights defenders and lawyers across Türkiye in the last year.
Arrests and protest bans
Last July, environmental activist Esra Işık was sentenced to more than two years for “resisting” a public official over what Amnesty International described as a peaceful protest against an urgent expropriation order linked to the expansion of coal mining in south-western Türkiye. She is appealing the conviction.
Ahead of a summit of the NATO alliance in the capital Ankara in July, authorities put in place a 13-day blanket ban on demonstrations, citing “national security”, and arrested over 200 people. Human Rights Watch said the crackdown showed Türkiye’s “ruthless intolerance of freedom of speech and assembly”.
Earlier this month, Turkish police detained dozens of people as part of what rights groups described as the government’s widening crackdown on LGBTQ+ activists and venues.
Questioned by media as to how he would guarantee the right to protest at COP31, Kurum said earlier in September that his team would “try to meet” any request they receive from civil society and give them “a free space to express themselves”.
“Don’t worry, thinking you will not be able to voice your opinions or really share your thoughts,” he said in an attempt to reassure campaigners, adding that he had put former deputy environment minister Mehmet Birpinar in charge of liaising with civil society.
Civic space needed
Camilla Pollera, human rights and climate change campaigner at the Center for International Environmental Law (CIEL), said meaningful participation at COP31 is fundamental to the legitimacy of climate action.
“At a climate summit, civil society participation necessarily includes being present, speaking out, scrutinising governments’ decisions and climate policies, and advocating for communities most vulnerable to climate change,” she added.
At last year’s COP30 summit, thousands of Indigenous people and climate activists peacefully marched through the Amazonian city of Belém in the first major demonstration outside the UN venue in four years. Smaller-scale demonstrations were largely confined to the “Blue Zone” at COP27 in Egypt, COP28 in the UAE and COP29 in Azerbaijan.
In two other separate incidents in Belém, members of the Munduruku tribe blocked access to the conference centre for hours, demanding an end to development projects in their ancestral land, and protesters stormed through the venue clashing with UN security officials.
The COP31 hosting agreement keeps some of the safeguards previously hailed by civil society groups. The government and the UN secretariat commit to upholding “the fundamental human rights” of all participants in the agreement’s preamble.
Under the deal, Türkiye also needs to ensure that security personnel follow “the highest ethical and professional standards and are expected to behave with integrity and respect”.

COP31 attendees told not to interfere in Türkiye’s “internal affairs”
As rising seas submerge growing swathes of land, countries that lose territory should still keep their national boundaries, sovereign rights and UN membership, according to a political declaration adopted at the UN General Assembly in New York on Thursday.
The declaration, which was championed by climate-vulnerable small island states, affirms “the presumption in favour of continued statehood” in the face of sea level rise fuelled by climate change, and urges countries to work together to assist communities affected by encroaching oceans.
Speaking at a high-level UN meeting to address the existential threats posed by sea level rise, Cabo Verde’s Prime Minister Francisco Carvalho, one of the initiative’s co-facilitators along with Australia, said the adoption of the text by consensus sends “a message of hope”.
“This declaration has a very special meaning. For us, sea level rise is neither a distant threat nor a theoretical concern,” he said, adding that rising seas put at risk key infrastructure, water resources and economic growth in small island states.
In the Pacific, sea levels have risen at twice the global rate, dramatically increasing coastal flooding events from two to 20 a year in the Republic of the Marshall Islands, and from zero to 102 events per year in American Samoa, according to the World Meteorological Organization (WMO).
Surangel Whipps Jr., president of the Pacific island of Palau, said the summit in New York represents a “moment of international solidarity”, and highlighted that small island states will remain permanent members of the UN.

UN Climate Summit: UN chief says world has tools to end fossil fuel age
At the UN Secretary-General’s climate summit in New York, countries shared their energy transition plans while Nepal and island nations advocated for more international support
Declaration recognises statehood
An advisory opinion by the world’s top maritime court, the International Tribunal on the Law of the Sea (ITLOS), first upheld in 2024 that countries do not have to shrink their maritime borders even if they lose land territory due to sea level rise. This was reiterated by the International Court of Justice in last year’s landmark ruling on the climate obligations of states.
The new declaration endorsed by all governments at the UN General Assembly stresses that sea level rise “is not a distant scenario but a real and lived experience for many”, and notes that international law must be implemented in global responses to rising seas.
UN Secretary-General António Guterres said the “milestone must now be translated into action”, adding that the declaration should encourage an “ongoing dialogue” at the “highest possible level” leading to practical outcomes. Pacific islands have proposed an international treaty on sea level rise that would provide more legal certainty.
“Those on the frontlines must be front and centre on every decision. We cannot allow countries and cultures to vanish beneath the waves,” he said. “The SOS has gone out. The world must answer.”
At regional summit, Pacific islands ask for COP31 support for clean energy and finance
Goodwin Friday, prime minister of St. Vincent and the Grenadines, said measures to protect vulnerable states will require adequate finance. “Investing in resilience now is more cost-effective than paying the far greater price for loss and damage later,” he added.
Championed by Australia’s COP31 co-presidency, Pacific islands have sought to put adaptation to sea level rise and ocean conservation at the top of the political agenda by inviting world leaders to attend the pre-COP31 summit co-hosted by Fiji and Tuvalu in October.
Tuvalu will also host the second global fossil fuel phase-out summit in April 2027, after around 60 governments met this year in Santa Marta, Colombia, to discuss ending their dependence on coal, oil and gas.
“Our coastlines, our reefs and our communities are living with the consequences of fossil fuel dependence every day, and our people have earned the right to help shape the way forward,” Lynda Tabuya, Fiji’s climate minister, said in a statement announcing details of the conference.
Ocean monitoring gets a boost in New York
Amid record-breaking marine heat and seas rising at unprecedented speed, governments in New York announced new commitments to protect the world’s ocean, as efforts to bolster marine ecosystems and coastal communities rise up the political agenda.
On Wednesday, the EU and Canada announced more funding for a new Europe-led ocean monitoring system called OceanEye, launched in the aftermath of a failed attempt by the Trump administration to dismantle the largest existing network of deep-sea observatories.
During an event at UN headquarters in New York, EU President Ursula von der Leyen and Canadian Prime Minister Mark Carney announced around $163 million in new funding for the initiative, with the EU pledging €92 million ($105m) on top of existing seed funding and Canada pledging C$82 million (US$58m) over five years.
According to an EU statement, while OceanEye will collaborate with the Global Ocean Observing System, that network “remains vulnerable to financial shortfalls and geopolitical disruptions”. A group of 30 countries from Europe, Africa and the Americas joined an international initiative in support of OceanEye, including large coastal nations like Brazil, Namibia and Mexico.
Von der Leyen said OceanEye “can make us the leading ocean data provider in a matter of years”, including by launching new satellites and installing new observatories in the deep ocean. “From outer space to the deepest ocean, our funding helps us keep watch beneath the waves,” she added.
Carney said the initiative would help protect Canada’s Arctic region with real-time monitoring operating year-round. “We can’t protect what we can’t see,” he said, also highlighting that Canada had expanded conservation of its ocean territory from 1% a decade ago to 15% now.
In New York, a group of 19 countries said they are either developing or implementing plans to sustainably manage all of their ocean territory, with 12 new nations joining the initiative. In a joint communiqué, they called on more countries to sign up ahead of COP31.
Warnings of El Niño-fuelled extreme heat
Scientists and world leaders have raised the alarm over this year’s record-breaking marine temperatures, which have persisted above historical peaks for more than 100 days as the naturally occurring El Niño phenomenon intensifies in the Pacific.
Extreme ocean heat could become a threat to coastal ecosystems and communities, experts fear. Water temperatures 1.5C above normal levels have also rapidly fuelled a strong hurricane in the Pacific in recent days.
Despite scientific calls for additional ocean conservation efforts, a report launched this week in New York warned that efforts to protect ocean ecosystems are lagging behind, with only 10% of the global ocean covered by conservation areas and just 3.5% designated as “effectively protected”.
