China’s carbon dioxide (CO2) emissions fell by 1% in the second quarter of 2026, as oil consumption plummeted amid the strait of Hormuz crisis.
The country’s use of oil fell by 9% overall and by 16% for transport, after the disruptions to supply from the Gulf through the strait.

China’s total CO2 emissions fell despite a continued rebound in coal-fired power generation.
This is the first time that reductions in oil consumption have been responsible for a fall in CO2 emissions overall – in all previous cases, coal consumption has been the main driver.
Other key findings for the second quarter of 2026 include:
- Electric vehicles (EVs) and public transport have become key factors in China’s oil demand, enabling transportation levels to increase even as fuel use fell sharply.
- The effect of EVs on oil consumption was almost twice as large as would be expected based on the increase in the number of EVs on the road alone, as the usage of existing EVs surged.
- Oil consumption displaced by EVs in China in the first half of 2026 exceeded the UK’s total oil consumption over a six-month period.
- These structural factors are not sufficient to account for the size of the fall in oil consumption, leaving behaviour changes as the other explanation.
- “Curtailment” of solar and wind output caused coal power to rise, despite strong hydro output, solar and wind capacity growth, as well as slower demand growth.
- Major increases in coal-power capacity and a power market that continues to favour coal limited the amount of coal generation displaced by new wind and solar capacity.
- Defying expectations of a boom, annual growth in coal use for chemicals production slowed down to 8%, from 15% in 2025 and 19% in the first quarter.
The second quarter of 2026 was a busy time for China’s government planners, with numerous energy-related five-year plan documents being released.
These plans list new measures to address solar and wind curtailment, as well as signalling a higher bar for the approval of new coal-power plants, but add few new quantitative targets.
After a 2% increase in the first quarter of 2026 and a 1% decline in the second, emissions are up marginally across the first half of the year, but they remain below their peak in 2023-24.
In addition, China is on track to add enough wind, solar, nuclear and hydropower this year to cover electricity demand growth, despite a slowdown in new capacity.
Given the structural pressures on oil demand, continued declines in real-estate construction and slower growth for coal-chemicals, China’s emissions could still fall this year. The emission trend remains a race between energy demand growth and clean-energy growth, both of which have slowed down this year.
Emissions still flat
There has now been a plateau in China’s CO2 emissions from fossil fuels and cement for more than two years, following a peak in March 2024.
Previous analysis for Carbon Brief described this as a “flat or falling” trend, which extended until the end of 2025. There was then a 2% increase in emissions year-on-year in the first quarter of 2026, resulting from a rise in the amount of “wasted” wind and solar power.
The latest analysis shows that this was followed by another decline in the second quarter of this year, when China’s emissions fell by 1%, as shown in the figure below.
For further details see: About the data.
Notably, China’s emissions fell in the second quarter despite an increase in coal use. For the first time ever, a drop in oil use was sufficient to drive a decline in emissions overall.
Oil use plummeted while coal grew
Within the overall 1% decline in China’s emissions in the second quarter of 2026, there were divergent trends when looking sector by sector and fuel by fuel.
The largest fall in CO2 emissions came from the consumption of petrol, diesel and jet fuel, with oil consumption in industry also falling, as shown in the figure below.
For further details see: About the data.
Crude oil processing volumes fell 11% in the second quarter, but some of the fall was absorbed by drawing down oil product inventories, with Sinopec sales down 9%.
In total, China cut back oil imports by 32% in the second quarter. The million–barrel question has been how much of this was enabled by genuine reductions in oil consumption and how much by the drawdown of the country’s vast oil stockpile.
Energy mix numbers reported by the National Bureau of Statistics indicate that oil consumption fell by 3% in the first half of the year and around 9% in the second quarter. This shows that reduced consumption played a substantial role, while still leaving 60% of the fall in imports to be covered by the swing from building stockpiles to using them.
The sector with the largest increase in emissions during the second quarter of the year was power, where coal use grew 2.4% while gas-fired generation fell 1.2%. This was despite strong growth in wind and solar capacity over the preceding year, a significant rebound in hydropower generation, a small increase in nuclear power output and a slowdown in electricity consumption growth.
The explanation for the rise in emissions was – similar to the first quarter of 2026 – an increased amount of solar and wind generation being “wasted” due to the power market and grid not being adapted to increasing shares of variable renewable generation.
In other sectors, there was a fall in cement production, driven by falling construction volumes, which accelerated to 9% in the second quarter, from 8% in the first quarter. Crude steel output fell by 1% and pig-iron production by 3% in the second quarter.
Growth of coal use for chemical production slowed down in the second quarter, both compared with the previous quarter and the last year.
The rate of utilisation of installed coal processing capacity was already high before the current oil shock, so there was no headroom for production to increase even though rising oil prices made coal-chemicals more profitable. Oil-based chemical production also kept growing, with ethylene output up 17% and primary plastics production flat.
Coal use for heating continued to increase, with the sector’s coal consumption in the second quarter dominated by industrial heat, as there is little need for space heating at this time of year. Growth has continued despite the prominent drive for “zero-carbon industrial parks”, demonstrating the importance of the initiative for tackling industrial coal use.
What drove the fall in oil consumption?
The dramatic fall in China’s demand for oil imports during the Hormuz crisis has been widely hailed as the most important price stabilising factor for the global oil market.
To understand the implications for China’s oil consumption and CO2 emissions going forward, it is important to unpack what enabled this reduction in imports.
A significant contribution comes from ongoing, structural reductions in transport oil demand driven by electrification. Sinopec had forecast 6% and 5% drops in diesel and petrol consumption this year, respectively, already before the start of the war on Iran. Actual sales fell 9% in the first half of the year.
Transportation levels show a slowdown in growth, but no outright decline. Cross-regional passenger trips were 0.1% higher year-on-year in the second quarter, while urban passenger trips were 2.9% higher. Commercial freight tonnage increased 2.4%.
The exception is air travel, where passenger numbers fell 7% in May-June, after 7% growth in the first quarter. However, this sector plays a minor role in overall transport oil consumption in China.
The stable or growing transportation levels show that the shift to electric vehicles, rail, public transport and other clean transportation, rather than a fall in mobility, played the key role in reducing oil consumption.
The rise in fuel prices that accompanied the Hormuz crisis only accelerated the structural shifts in transportation that were already underway.
Electric heavy-truck sales rose about 77% in the second quarter, year-on-year, with June sales more than doubling and the market share of electric trucks exceeding 45% of all new sales.
The total number of EVs on the road at the end of the quarter grew 33% year-on-year. Some 12.1m EVs were added, of which 8.1m were electric-only battery EVs.
EV usage saw even more of a shift. Charging volumes increased 60% in the second quarter, indicating that EVs already on the road were utilised much more than before, at the expense of petrol and diesel vehicles, with plug-in hybrid drivers likely favouring electricity over fuel.
One factor enabling EV utilisation to grow was the increased use of electric taxis. Intense competition in the sector has pushed prices down at the same time as the use of private petrol vehicles has become more expensive.
Stronger subway and rail use also made a contribution. Rail-passenger traffic increased 5% in the first half of the year.
The fall in diesel demand has been particularly pronounced in the construction and mining sectors. The heavy machinery in the sectors is well-suited for electrification, in addition to which construction levels are also falling.
Based on reported growth in charging volumes, EVs helped avoid an estimated 19m tonnes of oil consumption (Mtoe) in the second quarter, up 50% year-on-year.
This took the total amount of oil displaced by EVs to 36 Mtoe in the first half of the year, as shown in the figure below, well exceeding, say, the total oil consumption of the UK over six months. Notably, trucks are the fastest-growing source of oil displacement, with avoided fuel use up 90% year-on-year in the first half of 2026.
For further details see: About the data.
The increase in avoided oil consumption due to EVs is equal to 4.5% of China’s oil imports in the same period in 2025. If EV sales and charging volumes continue their growth at the same rates in the second half of the year, avoided oil consumption will reach 80 mn tonnes, equal to the consumption of Mexico.
Estimated emissions avoided are 35 MtCO2, or 1.3% of China’s total CO2 emissions in the second quarter, after taking into account emissions from power generation for vehicle charging.
While the amount of oil displaced by the shift to EVs is significant – and is rising fast – the year-on-year increase in displaced oil still only accounts for a third of the drop in China’s oil consumption in the first half of the year, with the fall in consumption only accounting for half of the drop in imports. The remaining reduction is due to the shift from building to drawing down stockpiles, slower growth in chemical industry output, as well as behavioral adaptations by consumers and operational adaptations by businesses.
Coal power continued to rise despite clean-capacity growth
China saw record increases in solar and wind capacity over the past year. In addition, hydropower generation increased 9% in the second quarter of the year, compared with the same period in 2025, and there was a small 2% increase in nuclear-power output.
At the same time, the rate of power demand growth slowed down from 5.9% in the second quarter of 2025 to 5.2% in the same period in 2026.
Yet, power-sector emissions increased 3.0% in the first half of 2026, after falling 3.2% in the first half of 2025. Power generation from fossil fuels rose because of an increase in the amount of potential solar and wind generation that was wasted, as well as exceptionally poor wind conditions. Without those factors, coal-fired power generation and power-sector emissions would also have fallen in 2026.
Wind-power capacity has continued strong growth in 2026, with capacity additions in both the first and the second quarter of the year comfortably exceeding those in any year other than the record-setting 2025.
Solar power additions have slowed sharply from the rates seen in 2025, even falling behind 2024. Yet, they are in line with 2023, when more than 200 gigawatts (GW) was added by year-end.
Nuclear power development continues at pace, with eight new reactors approved in July and five reactors with 4.5GW total capacity expected to enter commercial operation this year. This includes China’s second commercial small modular reactor, Linglong One, with new policies paving the way for further development.
Reactor commissioning will pick up further next year: the government has approved 10 new reactor projects every year since 2022 and those projects will begin to come online. Meanwhile, 3GW of conventional hydropower was added, with a total of 6GW of projects targeting operation in 2026.
Taken together, this clean-energy growth puts China on track to add enough non-fossil generating capacity in 2026 to cover electricity demand growth of up to 5%, despite the slowdown in solar.
Power demand grew 5.3% in the first six months of 2026 and the energy regulator projects 5-6% for the whole year. This means that the increase in power-sector emissions seen in the first half would be reversed, once the obstacles to solar and wind sending their output to the grid are addressed – and once wind conditions revert to average levels.
Moreover, total energy demand growth has slowed down much more sharply than electricity demand, making it more feasible for clean-power generation growth to significantly exceed the increase in total energy consumption and to drive down fossil-fuel consumption.
For further details see: About the data.
The key reason for solar and wind curtailment in China is that neither the power-grid operating model nor the electricity market model require – or encourage – the flexible operation of coal-power plants, hydropower plants and inter-provincial transmission lines.
This situation has been exacerbated by a wave of new coal-power plants entering operation, with newly added capacity reaching 30GW in the first half of 2026, the highest level since 2016. Another 25GW started construction, while less than 3GW was retired.
The electricity prices paid to coal-fired generators are fixed months in advance, as are the volumes of electricity that will be transmitted through long-distance power lines.
This removes the incentive for plants to adjust their output in response to conditions. This could include variations in solar and wind supply, or changes in power demand.
As a result, there is limited ability for the grid to absorb variable renewable power. Furthermore, coal plants are entitled to “capacity payments”, which require them to be available to generate, but do not reward them for operating flexibly.
One solution to integrate more solar and wind into the grid is increasing energy storage capacity. Battery storage capacity continued to grow, with 17GW added in the first half of 2026, bringing total installed capacity to 153GW. This represents a slowdown in storage additions, however, down from 23GW in the first half of 2025.
Outlook for China’s CO2 emissions
The key developments affecting the outlook for China’s emissions in the second quarter include the effects of the Hormuz oil-and-gas crisis, the release of a long list of sectoral five-year plans and a slowdown in energy consumption growth.
The rise in oil prices has caused a stronger shift in China’s transportation sector than anyone anticipated, with EV deployment and use accelerating from an already high base. This trend is unlikely to be reversed. It has also proven the value of electrification to China’s energy security strategy.
The government is targeting a slight acceleration in the pace of electrification, aiming for electricity to make up 35% of energy end-use by 2030, up from 30% in 2025. This is a larger increase than achieved over the past five years, when the share of electricity rose from 26.5% in 2020 to 30% by 2025. The transportation sector plays a significant role in this, with a target for EVs to make up 30% of the vehicle fleet, up from 12% in 2025, and 25% of commercial vehicles.
Electrification both reduces emissions immediately and sets different sectors up for deep decarbonisation as electricity is much easier to produce without CO2 emissions than fuels. Faster transport sector electrification lowers the outlook for oil demand, increases the role of the sector in peaking and reducing emissions, plus means that more of China’s clean energy growth ends up displacing oil.
While transport emissions fell, power-sector emissions continued to rebound for the second quarter in a row. The increased coal-fired power generation and emissions can be attributed to increased solar and wind curtailment. Curtailment has emerged as the key obstacle to both continued rapid solar and wind capacity growth and full utilisation of existing capacity.
Several sectoral five-year plans published in recent months have laid out measures to improve solar and wind utilisation.
Long-distance transmission will continue to expand, helping to move wind and solar generation from remote “energy bases” to centres of demand. There is also a growing emphasis on local consumption of clean power. The power sector five-year plan, published in August, promotes direct purchases of clean electricity, smart microgrids, zero-carbon industrial parks and closer coordination between renewable resources and AI computing infrastructure
Yet the same plan further loosened the limits on the amount of wind and solar that can be curtailed.
The limit for curtailment was 5%, until it was relaxed to 10% in 2024 in provinces with good wind and solar resources. The new plan allows the limit to be increased further to 15% for some provinces, while keeping it at 5% and 10% for others.
Looking at the 2025 data on reported curtailment, very few provinces had higher rates than 15% – only Tibet for wind and Qinghai and Tibet for solar.
Unless the most lenient limit is only applied to those two provinces, it means the plan would allow for higher levels of curtailment.
This is also true of the national average target of “around” 10% curtailment, given reported rates in 2025 were 94% and 95% for wind and solar, respectively.
Notably, monthly data on curtailment has not been published in recent months, raising the possibility that the indicator is being revised. Reported data has understated actual curtailment by a wide margin, compared to implied curtailment.
If the curtailment indicator is revised, such that it captures more of the actual curtailment, then this could make the headline targets stronger than they appear, in comparison to previously reported numbers.
The new five-year plans also lowered the overall level of ambition on coal use. Chinese president Xi Jinping announced in 2021 that China would “gradually reduce coal consumption during the 15th five-year period”, covering 2026-30. However, the target now is for coal consumption to “enter a plateau” during those five years.
The five-year plans call for “reasonably controlling coal-power capacity and generation”, signaling a higher bar for the approval for new coal-power projects, after the government’s active promotion of new coal power in recent years. This could also imply more retirements of older coal plants. However, there is 204GW of coal-power capacity under construction, even after the wave of new coal-power plants starting operation in 2025 and in the first half of 2026, making the implementation of the “reasonable control” more challenging.
It is the first time that the government has vowed to control “coal-power generation” and not just “generation growth”, as the energy regulator did in 2021, but the significance of that distinction is unclear.
The renewable energy five-year plan also broadens the concept of system reliability, which was a key justification for new coal power during the previous five years. Rather than relying primarily on coal-fired power for system stability, it increasingly looks to other options.
Alternatives include storage, flexible demand, EVs, “virtual power plants” and smarter system operation to provide balancing services. The plan also puts an emphasis on increasing the contribution of renewable energy to meeting demand peaks.
Therefore, while coal remains an important backup resource in the plan, reliability is no longer framed as something that can only be provided by coal.
The Chinese government has published numerous other sectoral five-year plans since its overarching plan came out in March. These include plans for the energy sector (“new-type energy system”), power system, renewable energy, carbon peaking, coal, climate-change mitigation, and the environment (“Beautiful China”). Some clear priorities emerge from these plans: electrification, electric vehicles, energy storage, offshore wind and “green”” fuels.
The energy plan also substantially increased ambition on the development of conventional hydropower, despite ecological and social risks and potential for tensions with neighbouring countries. The capacity additions will largely only materialise after 2030, however.
At the same time, energy consumption growth has slowed down markedly after the surge during and immediately after the “zero-Covid” period, making it more feasible for clean energy to meet all incremental demand.
If this trend continues, then total CO2 emissions will begin to fall even as power-sector emissions continue to plateau.
About the data
Data for the analysis was compiled from the National Bureau of Statistics of China, National Energy Administration of China, China Electricity Council and China Customs official data releases, as well as from industry data provider WIND Information and from Sinopec, China’s largest oil refiner.
Electricity generation from wind and solar, along with thermal power breakdown by fuel, was calculated by multiplying power generating capacity at the end of each month by monthly utilisation, using data reported by China Electricity Council through Wind Financial Terminal.
Total generation from thermal power and generation from hydropower and nuclear power were taken from National Bureau of Statistics monthly releases.
Total primary energy consumption is converted to the electricity equivalent using the substitution method.
Monthly utilisation data was not available for biomass, so the annual average of 52% for 2023 was applied. Power-sector coal consumption was estimated based on power generation from coal and the average heat rate of coal-fired power plants during each month, to avoid the issue with official coal consumption numbers affecting recent data.
CO2 emissions estimates are based on National Bureau of Statistics default calorific values of fuels and emissions factors from China’s latest national greenhouse gas emissions inventory, for the year 2021. The CO2 emissions factor for cement is based on annual estimates up to 2024.
For oil, total oil consumption is calculated based on energy mix data for the first quarter and first half of the year released by the National Bureau of Statistics. Consumption of transport fuels – diesel, petrol and jet fuel – is estimated based on the sales growth reported by Sinopec for the first quarter and the first half of the year, with monthly disaggregation based on production minus net exports. The consumption of these three fuels is labeled as oil product consumption in transportation, as it is the dominant sector for their use. Apparent consumption of other oil products is calculated as the residual.
Estimated non-energy use of fossil fuels is subtracted from total chemical industry fossil fuel consumption, and process emissions are calculated based on fossil fuel consumption with carbon retained in products subtracted. Emissions from the incineration of plastics are based on a peer-reviewed estimate of plastics incineration in 2022, combined with growth rates in the overall power generation from waste-to-energy plants. Metals industry process emissions are calculated using industrial output data and IPCC default emission factors.
Oil consumption displaced by EVs is estimated using China Association of Automobile Manufacturers’ sales data, via Wind Financial Terminal. The data breaks down vehicle sales by type and powertrain: passenger cars, buses, vans, semis and trucks of different sizes, each split into battery-electric and plug-in hybrid, with assumptions about how far each vehicle type is driven per year and the fuel economy of the conventional vehicle it replaces.
Annual mileage and fuel-consumption assumptions are compiled from different sources, including the International Council on Clean Transportation. Each electric vehicle sold is credited with avoiding the fuel a comparable internal-combustion vehicle would have burned; plug-in hybrids are credited only with the portion of driving done on electricity (a utility factor of 64%).
The electricity and oil figures are calibrated to figures from China’s National Energy Administration, which put new-energy-vehicle charging at 142.3 TWh in 2025 and reported 56.9% year-on-year growth in the first half of 2026. The second half of 2026 is a projection: each vehicle segment’s actual second-half-2025 displacement is grown by its first-half-2026 year-on-year rate.

Analysis: China’s CO2 emissions fall in Q2 2026 due to plummeting oil use
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.

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”.
