Candidates are being nominated to take over as the UN secretary general, when António Guterres steps down after nearly a decade in the role at the end of 2026.
Since becoming the ninth secretary general on 1 January 2017, Guterres has been a strong advocate for climate action, saying in January 2026:
“We have been outspoken on the urgent need for climate action, demanding ambition and working to rally governments, businesses and civil society.”
According to the UN, his predecessor, Ban Ki-moon, also “fought tirelessly to ensure that climate change stays at the top of the leaders’ agendas”.
Following a call for nominations going out in November last year, member states are currently nominating candidates to be the next secretary general.
To date, six candidates have been nominated by UN member states, with more expected in the coming months.
Below, Carbon Brief looks at the candidates’ views on climate change.
The UN secretary general’s role in climate action
The UN charter describes the secretary general as the organisation’s “chief administrative officer”.
According to the UN, they are a “symbol of UN ideals and a spokesperson for the interests of the world’s peoples, in particular the poor and vulnerable among them”.
It adds that the role is “[e]qual parts diplomat and advocate, civil servant and CEO”.
Over the past two decades, UN secretaries general have used their platform to advance action on climate change.
They have done so both by serving as a “moral authority” on climate change and as mediators in the drive to bring countries together, according to the UN.
Ban Ki-moon, the UN secretary general from 2007 to 2016, oversaw and brokered negotiations that culminated in the Paris Agreement, which he described as a “peace pact with the planet”.
Additionally, he pushed for its rapid ratification by member states so it could enter into force in record time compared to other treaties – such as its predecessor the Kyoto Protocol, which took eight years to come into force – with Ban securing an early buy-in from the US and China.
He also worked to mobilise $100bn per year by 2020 in climate financing from developed to developing countries. (The target was, ultimately, met two years late.)
His successor and current secretary general, Guterres, had been Portugal’s prime minister from 1995 to 2002, making him the first former national leader to hold the position.
Guterres served as the UN’s high commissioner for refugees between 2005 and 2015, a period that saw the highest level of human displacement since the second world war.
Guterres was the first secretary general to be elected through the current process, which includes public hearings and anonymous polling. (See: Next steps.)
He was chosen as the successful candidate in 2016, when he was voted in without opposition “in a rare show of unity” by members of the security council.
In his near-decade in office, he has become known for his references to the climate “emergency” and his calls for nations to make rapid emissions cuts.
Describing climate change as a “battle for our lives” and the Intergovernmental Panel on Climate Change’s (IPCC) 2021 report as a “code red for humanity”, Guterres has repeatedly demanded immediate action towards limiting global warming to 1.5C.
In 2024, as the world edged closer to hitting 1.5C of warming in an individual year, Guterres said:
“The battle to limit temperature rise to 1.5C will be won or lost in the 2020s – under the watch of leaders today.”
Besides repeatedly urging developed countries to meet their climate-finance obligations, Guterres has also intervened in attempts to resolve gridlocked negotiations at the annual “COP” climate summits.
He is known for his pointed advocacy on phasing out fossil fuels and for regularly convening states to submit more ambitious climate pledges.
The candidates
In the run-up to the UN general assembly in September 2026, nations are putting forward candidates for the secretary general position.
According to Reuters, tradition dictates that the role rotates between regions, with Latin America and the Caribbean next in line.
Thus far, five of the six candidates are from South or Central America: Michelle Bachelet Jeria; Rebeca Grynspan Mayufis; Rafael Mariano Grossi; María Fernanda Espinosa Garcés; and Carolyn Rodrigues Birkett.
The outlier is Macky Sall, a former Senegalese president nominated by the east African nation of Burundi.
Reuters adds that there is an “unwritten rule” that the secretary general never comes from one of the five permanent members of the UN security council – the UK, China, France, Russia and the US – to avoid an over-concentration of power.
In its 80-year history, a woman has never held the position of UN secretary general. Four of the six candidates nominated to date are women.
As shown below, this fact was noted “with regret” by a UN general assembly resolution in 2025, setting out the rules of the process to appoint the next secretary general.
Speaking during the first candidates’ debate, Espinosa Garcés quipped:
“I think, of course, a woman – it’s about time, isn’t it? After 80 years [of the UN’s existence].”
The debate was held in June by the UN Foundation, in collaboration with women’s organisation GWL Voices.
Bachelet, Espinosa and Grynspan took part in person at the event in Geneva, Switzerland.
(Sall sent in a video intervention, played at the beginning of the debate. Grossi was, according to the presenter, “not available” to participate and “chose not to send” a message by video.)
The three candidates were asked by an audience member how they would “ensure the climate governance becomes more equitable in response to those on the front lines of the crisis”, if they were elected as secretary-general.
Bachelet called for increased urgency in tackling climate change. Grynspan highlighted the need for action on adaptation as well as mitigation. Espinosa emphasised the need for a wide range of people to be involved in climate action, from Indigenous people to the financial sector.
The three participants all emphasised the need for finance in their responses. Bachelet, for example, specifically highlighting the need for grant-based finance. She said that “we cannot” keep asking “states that are fighting with a terrible debt” to accept climate-finance loans, which, ultimately, add to their debt. She added:
“They’re drowning and we’re asking them to ask for loans with a debt service that’s so big.”
All six candidates attended the Jeju Forum for Peace and Prosperity, co-hosted in Geneva by the Ban Ki-moon Foundation, at the end of June, ahead of the scheduling of further debates.
Additionally, for the first time in the selection process, candidates have been asked to voluntarily disclose their funding sources at the time of nomination.
Below, Carbon Brief details the candidates that have been nominated so far, what climate-relevant roles they have held previously and their views on climate change. (The list will be updated as further candidates are announced.)
Michelle Bachelet Jeria
Dr Michelle Bachelet Jeria is a Chilean diplomat, politician and doctor, nominated to be the next UN secretary general by Brazil and Mexico.
Bachelet was the former UN high commissioner for human rights, having served as its seventh commissioner from 2018 to 2022 and as the first director of UN Women.
She originally trained as a doctor – an education that was disrupted by being exiled in 1975 following the Chilean coup d’état led by general Augusto Pinochet – and specialised in paediatrics and public health.
In 1990, she began taking on roles in government bodies, including work in the Ministry of Health. This led her to further study, completing courses in military strategy and continental defence.
She became health minister in March 2000, before becoming the first woman to be the defence minister in Chile and Latin America in 2002.
Bachelet was elected as Chile’s first – and only – woman president, serving two terms: from 2006 to 2010 and 2014 to 2018.
As president and in public office, she consistently framed action on climate change as a human-rights obligation and a preventive tool to mitigate the worst impacts, arguing that “there is no space for [climate] denial”.
During her second term as Chile’s president, the share of renewables in the nation’s energy mix grew from 6% to 17% in four years. Bachelet also enacted South America’s first carbon tax and announced a 70% by 2050 renewable-energy goal, as well as expanding marine protected areas.
Among the range of international positions she has held over the last 20 years, Bachelet was named as the first director of the UN Women agency by former UN secretary general Ban.
Throughout her first term as high commissioner for human rights, Bachelet advocated for the protection of environmental defenders at risk, particularly in Latin America and the Caribbean, as well as women and girls impacted by climate change.
In a 2022 address to the UN human rights council following devastating fires in the Amazon, Bachelet remarked: “We are burning up our future – literally.” She continued:
“The world has never seen a threat to human rights of this scope. This is not a situation where any country, any institution, any policymaker can stand on the sidelines.
“The economies of all nations; the institutional, political, social and cultural fabric of every State, and the rights of all your people – and future generations – will be impacted.”
In an interview after she stepped down as human rights chief, Bachelet described the “triple planetary crisis – climate change, pollution and biodiversity loss” – as the “worst threat for humanity”.
In February 2026, she “broke new ground” when she was nominated by multiple UN member states – Chile, Mexico and Brazil – for the secretary general position.
However, in March, Chile’s newly sworn-in right-wing government, led by José Antonio Kast, withdrew its backing for Bachelet. Her nomination was dubbed “unviable” and a “mistake” by figures in the new government.
This is the first time a nominating state has withdrawn its support for a candidate. Bachelet’s candidacy is still supported by Brazil and Mexico.
Additionally, more than two dozen Republican US lawmakers accused Bachelet of “prioritis[ing] an extreme abortion agenda” in a letter earlier in 2026. They called for the US to veto her nomination.
She pushed back during a hearing in New York, US, saying that she “will always be by the side of women”.
In her pitch for secretary general, Bachelet calls for “simplify[ing] access to climate funds”, “innovative financial instruments” to address biodiversity loss and climate change and “sustainable responses that ensure climate justice, particularly for developing countries and vulnerable communities”.
She calls for debt relief, “true reform” of the international financial architecture, promoting investment in sustainable infrastructure and accelerating a just energy transition, with special attention to small-island states and least-developed countries. She says:
“From climate change to armed conflict, from growing inequality to technological disruption, the future of the UN will depend on its ability to adapt, renew and lead.”
Rebeca Grynspan Mayufis
Rebeca Grynspan Mayufis is a Costa Rican economist, diplomat and the former vice-president of Costa Rica. The nation backed her nomination.
In 2021, Grynspan became the first woman to be appointed secretary general of the UN Conference on Trade and Development (UNCTAD).
As part of this role, in February 2022, she outlined the UN’s vision for a sustainable recovery from the Covid-19 pandemic that “avoid[s] another lost decade of development for developing countries”.
In July 2022, Grynspan was credited with playing a “central” role in negotiating the Black Sea grain initiative struck between Russia, Ukraine, Turkey and the UN.
Brokered on behalf of the UN and as part of the Istanbul agreements, the initiative allowed grain and fertiliser exports blocked by Russia to resume to some of the world’s most food-insecure nations, with global food prices falling 23% in response to the deals.
In her pitch to become secretary general, Grynspan prioritises “durable peace and security” and UN reform as the first two of her three key priorities.
She warns that the world is “sleepwalking into dangerous climate-change scenarios”. Still, she adds that “technology offers new paths to development”, including through clean energy and critical minerals that are becoming “as valuable as oil”.
Grynspan has been especially vocal on the interconnections between climate and debt, observing that “financing is really key for any objective that we set to stick to the 1.5C target”.
Grynspan also supports the Bridgetown Initiative, championed by Barbados’ prime minister, Mia Mottley, to reform the global financial architecture and address debt and climate change, particularly in climate-vulnerable countries.
In her pitch, Grynspan warns that many millions “will continue to live in crushing scarcity and face compounding crises” if current trends continue.
These, she says, include small-island states “hit by cyclones that grow fiercer each year, landlocked nations facing the brunt of rising trade costs [and] developing economies servicing debt while capital moves past them”. She continues:
“Many states, including middle-income countries that are home to most of the world’s poor, struggle to fully access the trade, finance, technology and investment opportunities of the global economy.
“The UN must help widen the pathways to economic opportunities and help remove the structural constraints that stifle people’s potential. Sustainable development is not given, but unleashed.”
Rafael Mariano Grossi
Rafael Mariano Grossi is an Argentine diplomat and has served as the director-general of the UN’s nuclear watchdog – the International Atomic Energy Agency (IAEA) – since 2019.
Grossi was nominated by Argentina in November 2025.
A month later, Iran opposed his candidacy for failing to condemn US-Israeli attacks against “safeguarded, peaceful nuclear facilities”. It has since accused him of political bias and “destructive statements”.
While his “vision statement” for the UN does not directly mention “climate” or “climate change”, he refers to progress on the UN’s Sustainable Development Goals as “unfulfilled aspirations”.
Grossi suggests a “grounded, sectoral approach” to the world’s challenges through “collaborative partnerships” with “civil society, the private sector and the scientific community”.
In the statement – his pitch for the secretary general position – Grossi writes:
“Development cooperation must deliver tangible benefits, including access to health care, food, water and energy security, environment, education and real opportunities for a better quality of life, especially in countries facing the greatest challenges. Words must lead to action, and action to impact.”
Grossi takes credit for helping to achieve “global consensus around the need for nuclear power in the energy transition”.
At the UN climate summit COP28 in Dubai in 2023, Grossi delivered a statement saying:
“Net-zero needs nuclear power. The world needs nuclear power to fight climate change and action should be taken to expand the use of this clean energy source and help build a low-carbon bridge to the future.”
At the conference, a declaration to triple nuclear energy was endorsed by 22 national governments, including the US, France, the UAE and the UK.
More recently, Grossi has described the annual COP summits as “unmanageable” due to their size. According to the National, he has also “said he hoped to bridge the gap between climate agreements and growing energy demands, particularly in developing countries”.
Macky Sall
Macky Sall is a Senegalese politician who served as prime minister from 2004 to 2007 and then president from 2012 to 2024. He has been nominated by Burundi, which is currently the chair of the African Union (AU).
However, Sall’s candidacy has been rejected by other AU states, with Rwanda calling the use of a “silent procedure” to push through consensus on the African candidate for the position “a gross breach of AU rules and regulations”.
In his “vision statement”, Sall says that “peace and security cannot be sustained when the foundations of development are undermined by poverty, inequality, exclusion and climate vulnerability”.
While Sall underlines shortfalls in development financing, he emphasises that a “solidarity-based approach, founded on trust in crisis management, combined with sustained efforts for prevention and strengthening of early warning initiatives and mechanisms” is needed to address the challenges created by climate change.
Although Sall’s 12-year stint as president focused on “reducing power cuts and connecting remote villages to the power grid”, his candidacy is also facing charges of corruption, protestor crackdowns and media repression, according to Al Jazeera.
During the early part of Sall’s presidency, Senegal discovered oil and gas reserves – and the country’s oil exports have since surged from $0.4bn in 2015 to $2.4bn in 2024.
He was supportive of the African oil-and-gas sector, with much of the development of Senegal’s first oil production site undertaken during his term in office.
In 2019, a BBC Africa Eye investigation alleged that a company owned by Aliou Sall – Sall’s brother – received secret payments from businessmen who had obtained licences for two offshore gas blocks that same year. Sall denied the allegations.
María Fernanda Espinosa Garcés
María Fernanda Espinosa Garcés is an Ecuadorian linguist, poet, politician and conservationist. She was nominated by Antigua and Barbuda on 12 May, the only Caribbean state to put forward a candidate in this year’s selection process.
Espinosa was the president of the UN general assembly (UNGA) from 2018 to 2019. She has also served as Ecuador’s minister of foreign affairs twice, as well as its defence minister.
Before her political career, Espinosa was known for her work with Indigenous communities in the Ecuadorian Amazon and biodiversity conservation.
She established the socio-environmental studies programme at the Latin American Faculty of Social Sciences (FLACSO) and served as the regional director for South America at the International Union for the Conservation of Nature (IUCN) from 2005 to 2007.
Espinosa is no stranger to climate talks: she was Ecuador’s chief climate negotiator at UN COPs from Copenhagen in 2009 to Paris in 2015.
In a statement ahead of COP24 in Katowice, Poland, Espinosa – as UNGA president – remarked:
“I clearly remember the long negotiation days; the emotions, the frustrations, the sense of duty fulfilled in Cancun, Johannesburg or Copenhagen; the great hope of Paris. Clearly, we have come a long way, and much has been achieved, but we must rise to the new evidence and the new threats.
“The current climate crisis gives us now the opportunity to show the world that effective, results-oriented multilateralism is not an option but a survival necessity.”
In a 2024 paper, she lists fragmentation, “coordination challenges” and an “implementation deficit” as some of the key hurdles undermining the UN’s global environmental governance framework. She argues that its effectiveness “is significantly compromised by its very structure”.
In the same paper, Espinosa observes that the UNFCCC’s consensus-based decision-making “paradoxically contributes” to challenges in responding to climate change.
In her vision statement, Espinosa says that she plans to encourage a “more coherent international response” to support highly indebted, climate-vulnerable countries.
She states that the UN must act as a platform to strengthen cooperation on energy and support states during energy shocks.
According to Espinosa, “energy security, access, sustainability, trade and strategic autonomy are central to global stability”, with the energy transition “reshaping patterns of dependence and competition”.
She also says critical mineral extraction is being “unevenly distributed and developing at breakneck speed”.
If selected as secretary general, Espinosa plans to establish a “global energy security coordination mechanism” between UN member states and “other key actors” to manage the impacts of global energy shocks. These include impacts on energy access and affordability, food security, development and social stability, according to her nomination statement.
At a special UNGA meeting on climate ambition and sustainable development in 2019, Espinosa warned the gathering:
“We are the last generation that can prevent irreparable damage to our planet. Climate justice is intergenerational justice.”
Carolyn Rodrigues Birkett
Carolyn Rodrigues-Birkett is a politician, diplomat, former school teacher and Guyana’s permanent representative to the UN. She was nominated by her home nation on 15 June 2026, becoming the first Indigenous candidate in the current elections.
Rodrigues-Birkett served as Guyana’s minister for Amerindian affairs – the Indigenous population – in 2001 and 2006.
Appointed at the age of 27, Birkett is widely recognised as one of the “architects” of the Amerindian Act of 2006 – a piece of legislation described as “a milestone for Amerindian land rights, not only in Guyana but the western hemisphere”.
The act codified Indigenous land rights, governance and mandates their consent before mining or development projects on communally owned forest land.
In 2008, Birkett was appointed the country’s minister for foreign affairs and trade for two terms, the first and youngest woman of Indigenous descent to rise to the role.
Birkett has served as Guyana’s envoy in the security council in its two-year tenure between 2024 to 2025, supporting statements on the linkages between climate, peace, security and food insecurity.
Between 2015 and 2020, she coordinated the Food and Agriculture Organization’s (FAO) work with other UN organisations and its outreach to parliamentarians, particularly in Africa, Latin America and the Caribbean.
In her vision statement for the role, Birkett places a strong emphasis on climate finance and unmet sustainable development goals. She says:
“While trillions exist globally in potential financing, many developing countries continue to struggle with access. There has also been a profound shift in the risk landscape characterised by interconnected threats and climate-related challenges.”
The new secretary general, she says, must work with member states to “champion the implementation of existing commitments”. She adds that “there must be continued support to [m]ember [s]tates as they implement agreed” climate commitments.
If elected, Birkett pledges to use the secretary general’s convening powers to “bring all stakeholders together to address climate impacts and protect the environment”.
Next steps
While parties were encouraged to submit their candidates by April 2026, they can continue to make nominations for the next UN secretary general until the end of July.
At this point, the 15-member security council will begin to discuss the candidates “behind closed doors”.
Candidates will need to clear a “straw poll” vote by the council. These are informal, anonymous ballots to determine the viability of candidates.
Security council members have the option to “encourage” or “discourage” a candidate within these straw polls, as well as state that they have no opinion.
Polls are run numerous times until a consensus is found on a candidate. For example, when Guterres was selected in 2016, it took six straw polls for the council to reach agreement.
The selected candidate is then publicly put to a vote, in which non-permanent members of the council have a single vote and the five permanent members each have a power of veto.
This results in a council “resolution”, recommending the appointment of a candidate. This resolution must secure support from nine out of 15 members and no vetoes to pass.
Subsequently, there is a formal vote by the UN general assembly to endorse the council’s recommendation – although Reuters notes that this final vote has “long been seen as a rubber stamp”.
Ultimately, the security council process is likely to be finalised between August and October, ahead of the general assembly formalising the appointment at the end of the year.
The next secretary general is due to take office on 1 January 2027.

Q&A: Where do the UN secretary general candidates stand on climate change?
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”.

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”.
