The amount of UK electricity generated from fossil fuels fell 22% year-on-year in 2023 to the lowest level since 1957, Carbon Brief analysis reveals.
The 104 terawatt hours (TWh) generated from fossil fuels in 2023 is the lowest level in 66 years. Back then, Harold Macmillan was the UK prime minister and the Beatles’ John Lennon and Paul McCartney had just met for the first time.
Electricity from fossil fuels has now fallen by two-thirds (199TWh) since peaking in 2008. Within that total, coal has dropped by 115TWh (97%) and gas by 80TWh (45%).
These declines have been caused by the rapid expansion of renewable energy (up six-fold since 2008, some 113TWh) and by lower electricity demand (down 21% since 2008, some 83TWh).
As a result, fossil fuels made up just 33% of UK electricity supplies in 2023 – their lowest ever share – of which gas was 31%, coal just over 1% and oil just below 1%.
Low-carbon sources made up 56% of the total, of which renewables were 43% and nuclear 13%. The remainder is from imports (7%) and other sources (3%), such as waste incineration.
Overall, the electricity generated in the UK in 2023 had the lowest-ever carbon intensity, with an average of 162g of carbon dioxide per kilowatt hour (gCO2/kWh).
This remains a long way from the government’s ambition for 95% low-carbon electricity by 2030 – just seven years from now – and a fully decarbonised grid by 2035.
Fossil falls
Historically, fossil-fuel generation rose steadily as the size of the UK’s economy expanded – and, relatedly, as demand for electricity grew.
The rise in demand for electricity paused during the late 1970s and 1980s, as the country’s economic situation and industrial relations worsened. Yet the upwards march soon resumed.
Electricity demand then started to “decouple” from economic growth in the early 2000s, leading to a peak in 2005. Since then, demand has dropped precipitously, falling from 396TWh in 2008 to 313TWh in 2023, as shown by the dark blue line in the figure below.
This reduction in demand of 83TWh (21%) is equivalent to more than three times the expected output of the Hinkley Point C nuclear power plant, which is currently being built in Somerset.
Demand reductions are the result of a poorly understood combination of more efficient appliances and lighting, high prices driven by expensive gas and changes in the structure of the UK as it shifts to an ever more service-led rather than manufacturing-heavy economy.
(In the medium- to long-term, electricity demand is expected to rise as transport and heating are increasingly electrified using electric vehicles and heat pumps.)
While electricity demand was falling, the UK was also starting to rapidly scale its renewable energy capacity, primarily from wind, but also from solar and bioenergy.
As a result, renewable electricity output climbed six-fold from 23TWh in 2008 to 135TWh in 2023, shown by the red line in the chart below.
The combined impact of falling demand (-83TWh) and rising renewables (+113TWh) has acted as a pincer on electricity generation from fossil fuels, squeezing it from two directions.
Having peaked at 303TWh in 2008, the UK got just 104TWh of electricity from fossil fuels in 2023 – as shown by the steep black line in the figure below – a two-thirds reduction in 15 years. This takes fossil-fuel generation to its lowest level since 1957.

In 1957, the Conservative party’s Harold Macmillan was elected UK prime minister in January following Anthony Eden’s resignation due to ill health.
That same year, the Central Electricity Generating Board was established ‘to keep the lights on’. It was responsible for electricity generation, transmission and bulk sales in England and Wales up until the electricity sector was privatised in the 1990s.
The world’s first commercial nuclear power station, at Calder Hall in Cumbria, had just opened its second unit, yet fossil fuels still supplied 97% of the UK’s electricity.
Also that year, the Suez canal was reopened, “Sputnik 1” – the first artificial satellite to orbit Earth – was launched by the Soviet Union and the UK government unveiled plans to allow women to join the House of Lords for the first time.
Shifting shares
For most of the past century, fossil fuels generated almost all of the UK’s electricity, as shown by the black line in the figure below. Fossil fuels – predominantly coal – made up 97% of the total in 1957, a figure that had barely changed for decades.
The rise of nuclear power (dark blue line) from the late 1950s onwards – after Calder Hall opened in 1956 – pushed the fossil fuel share downwards.
Yet electricity demand continued to grow and the earliest nuclear reactors were starting to shut down by the early 2000s, with only Sizewell B in Suffolk, in 1995, having replaced them.
With renewables still in their infancy, this meant that, in 2008, the UK was still getting 76% of its electricity from fossil fuels. Of this, 45% was from gas and 30% from coal.
Since then, fossil fuels’ share has dropped to a record-low 33% in 2023, being overtaken by renewables in the process (red line).
Renewables’ share reached a record high of 43% in 2023, with nuclear (13%, light blue line), imports (7%) and other sources (3%) making up the remainder.

The total share from low-carbon sources – renewables and nuclear – was 56% in 2023. This was down one point from the record 57% share in 2022, as a result of a drop in nuclear output.
The current government’s ambition is to get 95% of the country’s electricity from low-carbon sources by 2030, which would mean an increase of 39 percentage points in seven years.
To date, the fastest rate of increase has been 25 percentage points in seven years, achieved between 2010 (23% low-carbon) and 2017 (48%).
The aim is then to fully decarbonise the grid by 2035. The opposition Labour Party’s aim is even more ambitious, hoping to fully decarbonise the electricity grid already by 2030. This would be a 44 percentage point increase in seven years.
Renewable rise
The rise of renewables since 2008 has been nearly as steep as the fall for fossil fuels, as shown by the red line in the figure below.
Notably, however, since reaching 134TWh in 2020, renewables have effectively stood still, with output of 135TWh in 2023, matching the record 135TWh set in 2022.
This reflects the balance between continued increases in wind and solar capacity, variations in average weather conditions and reduced output in the past two years from bioenergy.
The 135TWh of renewable electricity in 2023 was made up of:
- 82TWh from wind (up 2TWh year-on-year, a 2% increase);
- 35TWh from bioenergy (down 5TWh and 13% from 2021 levels);
- 14TWh from solar (up 2% year-on-year);
- 5TWh from hydro (down 1TWh year-on-year, a 9% drop).
At the same time, coal has nearly disappeared from the UK electricity system, falling from 119TWh in 2008 to 4TWh in 2023 (down 115TWh, 97%), shown by the black line below.
Gas, meanwhile, is now down to levels rarely seen since the mid-1990s (grey line), falling from 178TWh in 2008 to just 98TWh in 2023 (down 80TWh, 45%).
Nuclear also continues to decline, reaching 41TWh in 2023, a 7TWh reduction year-on-year (15%) from already low levels, after Hinkley Point B in Somerset closed down and the remaining five stations were temporarily offline for planned maintenance outages.

Capacity for both onshore and offshore wind projects rose in 2023, by 0.6GW and 1.1GW, respectively.
Average wind speeds in the first 11 months of 2023 were well below the long-term average however, according to government figures, whereas 2022 had only been marginally below average. This muted overall generation growth over the last year somewhat.
A windy December helped boost overall generation figures for the year, with a new wind generation provisionally set on 21 December according to National Grid ESO. Wind generation hit 21.8GW between 8:00 and 8:30 on 21 December, providing 56% of the generation mix.
Notably, only one offshore windfarm was completed in 2023 – the 1GW Seagreen development off the east coast of Scotland – whereas three projects totalling 3GW were commissioned in 2022.
In October 2023, Dogger Bank off the coast of Yorkshire sent power to the national grid for the first time. It will be the world’s largest offshore windfarm, at 3.6GW, when it is completed in 2026.
Nevertheless, the government’s ambition for 50GW of offshore wind by 2030 is in doubt after the latest auction for new renewable capacity failed to secure any additional projects.
For bioenergy, the 35TWh in 2023 was similar to the level delivered in 2022, but down from 40TWh in 2020 and 2021. Plant biomass – mainly woodchips – is around two-thirds of these annual totals.
The four wood-burning former coal units at the Drax plant in Yorkshire account for around one-third of power from bioenergy on their own. However, their output has been subdued in 2022 and 2023, with some reporting having raised questions about the incentives at play.
Meanwhile, electricity generation from solar power only increased by 2% in 2023, despite a surge in new capacity being connected to the grid.
The number of hours of sunshine during 2023 was roughly in line with the long-term average, government figures show, whereas 2022 had been unusually sunny.
According to figures from consultancy Rystad Energy cited by Drax Electric Insights, the UK’s solar capacity was expected to rise from 15GW at the start of 2023 to 18GW by the end of the year.
Recent growth in solar installations comes after an extended period of stagnation, with installed capacity having reached 13GW in 2018 and only climbing to 14GW in 2022.
Rystad Energy expects UK solar capacity to continue accelerating, topping 25GW in 2025.
The latest reduction in coal generation, down another 33% in 2023, came as three of the UK’s four remaining coal-fired power stations shut down.

West Burton in Nottinghamshire closed in March, then Drax in Yorkshire closed in April, followed by Kilroot in Northern Ireland at the end of September.
Only Ratcliffe in Nottinghamshire, operated by utility firm Uniper, remains operational. It plans to close in September 2024, ahead of the government’s ambition to end coal power by October 2024.
While the UK saw a major coal-to-gas transition in the 1990s “dash for gas”, recent reductions in coal use have been driven by renewables and reduced demand. These same forces have also been driving gas out of the mix.
The large drop in gas generation in 2023 of 27TWh (21%) reflects a combination of this longer-term trend with a one-off flip in the UK’s electricity imports.
The dip in the dark blue line for “oil, imports and other” in 2022 is due to the UK becoming a net electricity exporter that year for the first time ever.
Every year since the opening of the first “interconnector” linking the grids of the UK and France in 1986, the UK has been a net electricity importer – apart from 2022.
The switch in 2022 was due to widespread outages in the French nuclear fleet, with neighbouring countries including the UK picking up the slack.
In 2023, the UK reverted to being a net importer, buying 23TWh of electricity from countries including France, the Netherlands, Belgium and Norway. This was similar to 2021 (25TWh).
The switch from being a net exporter of 5TWh in 2022 to net imports of 23TWh in 2023 combined with steady output from renewables and falling demand to push down the need for fossil fuels.
The UK now has 8.4 gigawatts (GW) of interconnector capacity to link its electricity system with that of neighbouring countries. Some 4.4GW of this has been added in the past five years.
In addition, the 1.4GW Viking Link interconnector between the UK and Denmark was completed in late 2023 and was due to have started operating in late December.
Another 4.7GW has regulatory approval, with further projects totalling 5.6GW also planned.
Cleanest power
With fossil fuels reaching a record-low 33% share and coal down to 1% of the total, the UK saw its lowest-carbon electricity mix ever in 2023.
The carbon intensity of electricity – in other words, the amount of CO2 associated with each unit of electricity – fell to a record-low 162gCO2/kWh in 2023, a reduction of 18% year-on-year.
This continues a longer-term trend, shown in the figure below. In the early years of the series, the reductions in carbon intensity reflect a shift towards more efficient power plants.
The expansion of nuclear power in the 1970s and 1980s was followed by the “dash for gas”, which is lower-carbon than coal. From around 2008, the decline is due to the rise of renewables.

The government had earlier set a goal of reducing the carbon intensity of electricity generation to below 100gCO2/kWh by 2030. Since then, the UK’s 2050 climate target has been strengthened from an 80% cut in emissions to a 100% cut – reaching net-zero by that date.
If the government reaches its aim of 95% low-carbon electricity by 2030 then the carbon intensity of generation would fall to well-below 100gCO2/kWh. Just how far below would depend on the contribution from bioenergy and whether CO2 associated with imported electricity is counted.
The figure above counts bioenergy lifecycle emissions and imports towards the total.
Methodology
The figures in the article are from Carbon Brief analysis of data from DESNZ Energy Trends chapter 5 and chapter 6, as well as from BM Reports. The figures from BM Reports are for electricity supplied to the grid in Great Britain only and are adjusted to include Northern Ireland.
In Carbon Brief’s analysis, the BM Reports numbers are also adjusted to account for electricity used by power plants on site and for generation by plants not connected to the high-voltage national grid. This includes many onshore windfarms, as well as industrial gas combined heat and power plants and those burning landfill gas, waste or sewage gas.
The analysis of carbon intensity is based on the methodology published by National Grid ESO, but also takes account of fuel use efficiency for earlier years.
DESNZ historical electricity data, including years before 2009, is adjusted in line with other figures and combined with data on imports from a separate DESNZ dataset. Note that the data prior to 1951 only includes “major” power producers.

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

Climate Change
In Guatemala, Indigenous women build climate resilience with old and new farming methods
In Guatemala’s southwest region lies a large lake with a storied history.
Lake Atitlán is one of Central America’s most critical local sources of drinking water, and is surrounded by volcanoes, a thriving tourism industry and an ancient Mayan culture. The Sololá region has long been home to Indigenous communities who have been attracted to its fertile land and pristine natural resources.
But in recent years, this site of natural beauty in Guatemala’s highlands has had to contend with the growing impacts of the climate and nature crises. Climate change is disrupting the rain cycle and significant areas of land show signs of erosion and loss of soil fertility. These changes are threatening crop production and pushing local people into food insecurity.
Elena Wason, co-executive director at Natün, a local non-profit supporting Indigenous people, told Climate Home News that community leaders have “identified deforestation and the effects of climate change in their communities as among their greatest concerns”. Forest cover declined by an estimated 12% in the past two years alone.
Women are often the social group most exposed to these changes and Natün has focused its efforts on reviving Indigenous agriculture techniques in a bid to improve climate resilience and empower female farmers.
How to fight drought
The impacts of climate change on Indigenous communities can often lead to further environmental damage as farmers are forced to rely on unsustainable practices, such as cutting down trees to clear more land. This can accelerate water scarcity, soil erosion and ultimately food insecurity.
An ongoing adaptation project led by Natün has sought to reverse these impacts, working with local people to combine modern climate-smart agriculture and ancestral knowledge. The approach involves the use of drought-resistant crops, organic pest management and soil conservation techniques. This is increasingly recognised as an effective way to strengthen climate resilience.
“Our approach is based on soil analysis and the use of locally resilient, endemic tree species, significantly increasing survival rates and ensuring sustainable water availability despite changing rainfall patterns,” Wason explained.


A US$170,000 grant from the Adaptation Fund-UNDP innovation platform (through the AFCIA programme) also allowed it to scale. For example, Natün established over 300 family food gardens – small spaces with shared resources that focus on growing nutrient-rich crops.
The project was built for the long-term by embedding innovation within Indigenous knowledge systems, organic farming and Mayan land stewardship rather than imposing external solutions. In this way, it ensures that communities remain the architects of their own resilience. Diversified revenue streams, including carbon credits and replicable learning kits, further support its longevity.
Nearly all of the typical Mayan gardens are managed by women, with the project training up to 30 women in climate-resilient practices, such as seed bank management. The approach has paid dividends by bolstering local food security and providing almost 19,000 people with sustainable food sources.
Young South Africans take up sustainable agriculture for food security
“The project uses locally led innovation by helping to restore sustainable Indigenous Mayan practices, while empowering vulnerable communities and women to build resilience and adapt to climate change and bolster food security,” said Mikko Ollikainen, head of the Adaptation Fund.
“Community-led approaches like these can have profound positive impacts on the directly affected communities and beyond by creating practical scalable solutions,” he added.
Growing incomes
The programme was expanded in 2025 with the creation of over 260 small poultry farms, further diversifying family incomes. The early results have been positive: two-thirds of families with both a garden and poultry now have surplus produce and incomes that have grown by an estimated $61 per month.
“These impacts especially benefit women, who not only make up 75% of programme participants and have taken leadership roles in managing community gardens, but also generally take on the responsibility of providing nutritious food for their families,” said Wason.
The project follows an earlier $5.4 million activity in Guatemala, also funded by the Adaptation Fund, that focused on honey bee production, forest conservation and ancestral knowledge across Suchitepéquez and Sololá. The aim was to empower vulnerable communities and Indigenous populations to adapt to floods and landslides, while enhancing diverse production landscapes and livelihoods.
Advancing women’s rights and empowerment in climate adaptation
That project resulted in 6,093 hectares under forest management and conservation, nearly 1,500 beehives in operation, and 328 family gardens with the purpose of helping women adapt. Utilising such ancestral practices have helped to increase agricultural resilience in the Nahualate River basin, benefiting some 1,125 people.


Enduring benefits
The long-term benefits of the Lake Atitlán project will be in providing communities, especially women, with practical tools to respond to the environmental challenges of drought, storms and deforestation in the Sololá region. These challenges are becoming more pronounced as the climate becomes more extreme and unpredictable.
Guatemala is ranked among the most exposed countries to climate risk. The World Bank estimates that up to 83% of its GDP is generated in areas prone to disasters. As such, it is not only the people around Lake Atitlán who stand to benefit from sustainable farming techniques.
The Natün project is easily replicable by harnessing local knowledge and offering a practical model that can be adapted across Indigenous communities facing similar climate pressures. In a country with an Indigenous population of over 6 million people, this approach will be of importance to many other communities as they face similar existential crises in a warming world.

World Bank’s climate work can endure without finance target, experts say
The World Bank has scrapped its headline climate finance target under pressure from the Trump administration, but experts believe the survival of its wider climate programme should preserve support for clean energy and resilience in developing nations.
Following tense negotiations between its government shareholders, the global lender announced this week it would extend its Climate Change Action Plan (CCAP) while “retiring” its commitment to direct 45% of its financing to projects with climate benefits – a target it has already met.
“It could have been a lot worse,” said Danny Scull, a senior policy advisor at think-tank E3G. “I would have loved to see the most ambitious outcome possible, but it is far less likely we’ll see a scenario where the bank all of a sudden reverses its current trajectory and starts delivering less on climate,” he added.
Introduced in 2021, the CCAP has been credited with overhauling the World Bank’s approach to climate finance after years of criticism over the development finance institution’s lukewarm support for cutting planet-heating emissions and building resilience to extreme weather and rising seas.
Since the CCAP began, the World Bank’s climate finance nearly doubled to $39.2 billion in 2025, with 48% of its financing showing climate “co-benefits” and exceeding the target first set at COP28.
US attack partially rebuffed
With the CCAP due to lapse at the end of June, the US – the World Bank’s largest shareholder – mounted a campaign for the lender to axe the programme entirely. Last April, US Treasury Secretary Scott Bessent publicly welcomed the plan’s upcoming expiration, urging the bank to “shift its myopic focus on climate” and abandon its “distortionary” 45% climate finance target.
But Washington was left increasingly isolated during protracted negotiations in recent months as both European governments and a wide-ranging coalition of developing countries held firm on the plan’s extension, sources with knowledge of the discussions told Climate Home News.
In May, executive directors representing a bloc of nearly 100 countries, including China, Brazil, Saudi Arabia and Russia, sent a letter to the World Bank’s board requesting the CCAP be extended and calling for an independent review of the programme.
While the US had previously seemed unwilling to compromise with its European counterparts, that intervention got it to “back off from its most extreme positions”, E3G’s Scull said.
Focus on “outcomes”
In its statement on Monday, the World Bank Group said it would place less weight on the amount of money flowing into projects with climate benefits and shift its focus to “outcomes”, including indicators such as greenhouse gas emissions avoided and the number of people better shielded from climate risks.
The UK’s international development minister, Jenny Chapman, said in a post on LinkedIn this week that the extension of the CCAP is “a critical step forward”, adding that the stronger emphasis on results “is essential to ensure maximum impact, and the UK will hold the Bank to account to ensure delivery”.
Despite ditching its headline goal, the international lender is still expected to keep counting the volumes of climate finance for the vast majority of its activities. That’s because the individual entities belonging to the group continue to have their own climate targets embedded in their current mandates.

For example, the International Development Association (IDA), which supports the world’s poorest nations, has committed to providing 45% of its funding to climate-related activities until 2028. And its larger lending arm, the International Bank for Reconstruction and Development (IBRD), should keep aiming for 30% of its financing to have climate benefits.
Joe Thwaites, a climate finance expert at the Natural Resources Defense Council (NRDC), said these targets “can be a backstop against the bottom falling out”. “Client countries are emphasising that they want to see more investments in clean energy and resilience,” he added.
No major change expected
The World Bank’s provision of climate finance is also crucial for wealthy countries’ efforts to meet a commitment to provide $300 billion a year for developing countries by 2035 under the new UN climate goal agreed at COP29 in 2024.
That year, multilateral development banks (MDBs) accounted for around half of all climate finance provided by developed countries under the previous $100-billion-a-year goal, according to calculations by the Organisation for Economic Co-operation and Development.
UK development minister Chapman said this week that the bank “must continue to meet the expectations of the wider international community, including those set out at COP29”. There, MDBs said that by 2030, their annual joint climate financing for low- and middle-income countries would reach an estimated $120 billion.

Rajneesh Bhuee, just transition lead at campaign group Recourse, said it was a “blow” that the World Bank’s headline target had been dropped, but she doesn’t expect to see climate financing reducing – at least in the short term.
“This is the [bank] management’s way of alleviating pressure from the US and ensuring they can have some sort of calm internally,” she told Climate Home News.
Thwaites said shareholder countries should hold the bank’s leadership accountable for delivering what countries have “agreed and need” on climate action.
“If World Bank climate finance does start to fall, donors should focus their support on other international financial institutions that continue to prioritise climate,” he added.
IMF also steps back from climate focus
Regional development banks outside of the Americas may be under less pressure to water down their climate mission. But the World Bank’s sister institution – the International Monetary Fund (IMF) – has seen its enthusiasm for climate action ebb, according to a report released in June by its official watchdog, the Independent Evaluation Office.
The report said that in 2021, the fund placed great emphasis on tackling climate change, as shown by its flagship climate strategy published that year and the establishment of the Resilience and Security Trust in 2022.
But in the last year or so, it found “decreasing emphasis on climate-related issues” which coincided with IMF cost-cutting, “emerging geopolitical challenges” and reduced support for climate action from some unnamed IMF member countries.
Last year, US finance minister Bessent accused the IMF of “mission creep”, accusing it of spending too much time on climate action, gender and social issues.
The evaluation report found that the focus on climate change among the IMF’s management and executive board has weakened, and its flagship reports have not included any climate-related chapters since 2023. IMF head Kristalina Georgieva and other managers mentioned climate-related terms in speeches and statements to the board far less in 2025 than the preceding years, it noted.
While most of the nearly 700 IMF’s staff surveyed welcomed the swing away from climate work, others bemoaned it and felt “self censored” when working to promote awareness of the risks of climate change to the global economy – which the IMF is tasked with protecting.
