The year 2023 saw the coronation at Westminster Abbey of a new king, the mugshot of a former US president and the rebranding of a social media platform to a single letter.
But behind the biggest stories of the year, thousands of studies detailing new research also made the headlines. And climate change and energy were among the topics that received the most attention.
Each year, Altmetric tracks how often research papers from academic journals are mentioned in online news articles as well as on blogs and social media platforms. It then gives each paper a score according to the attention it receives.
Using Altmetric data for 2023, Carbon Brief has compiled its annual list of the 25 most talked-about climate- or energy-related papers that were published the previous year.
(The list focuses on peer-reviewed research papers only – commentaries or other papers that are not formally peer-reviewed are not included.)
The infographic above shows which papers made it into the top 10, while the article includes analysis of the full list of 25, including the diversity of their authors and which journals feature most frequently.
The list covers research into the climate projections of a major oil company, the human cost of global warming and the catastrophic failure of breeding penguins – as well as the curious case of the high-scoring paper that received almost no news coverage at all.
Antarctic ice shelves
The most talked-about journal papers of 2023 are again dominated by research relating to Covid-19, continuing the pattern seen in recent years.
For example, the highest-scoring paper of any published in 2023 is a review into the effectiveness of measures to reduce the spread of respiratory viruses, such as Covid, swine flu and severe acute respiratory syndrome (Sars).
The study’s Altmetric score of 25,730 puts it almost 10,000 points ahead of the second-placed paper, which is also about Covid.
But the top-scoring paper relating to climate is not far behind, landing fourth in the overall list with a score of 13,886.
The study, “Change in Antarctic ice shelf area from 2009 to 2019”, gains the highest score for any climate paper in any of Carbon Brief’s annual reviews by some distance – the previous highest was 7,803 in 2022.
(For Carbon Brief’s previous Altmetric articles, see the links for 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2015.)
The study, published in the Cryosphere, uses satellite observations to produce a dataset of changes in the “calving front” – that is, where icebergs break off – and area of the ice shelves that surround Antarctica between 2009 and 2019. It shows that, overall, the area of Antarctic ice shelves has grown by around 5,300 square kilometres (km2) since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area.
Specifically, ice-shelf area has decreased on the Antarctic Peninsula (by 6,693km2) and in west Antarctica (by 5,563km2), and increased in east Antarctica (by 3,532km2) and on the large Ross and Ronne-Filchner ice shelves (by 14,028km2), the paper says.
The map from the study below shows the growth (blue) and retreat (red) of ice shelves around Antarctica, where the size of the circles indicates the scale of the change from 2009 to 2019.
While the high scores of climate-related papers in previous years have primarily been driven by news coverage, this paper appears in just seven news stories.
As study author Prof Anna Hogg from the University of Leeds explains to Carbon Brief:
“Somewhat unusually, we didn’t put out a press release for the paper as we assumed the scientific community that needed the dataset would make use of it naturally.”
Instead, the paper’s high Altmetric score is principally a result of a huge number of mentions on Twitter – more than 63,000 posts from around 48,000 accounts. (Altmetric includes weightings in its scoring system, so news articles (with a weighting of eight) are deemed to have more impact than tweets (0.25).)
A closer look suggests that the paper has been widely quoted by the Twitter accounts of a number of prominent climate sceptics in an attempt to push back on concerns around climate change and the loss of Antarctic ice. These posts have then been widely retweeted by other accounts.
To see the paper “being used as evidence to suggest that climate change isn’t happening” was a “real surprise”, says Hogg, because the paper “doesn’t make any such statement”.
Specifically, the gains the study identifies in ice-shelf area in east Antarctica do not detract from the risks of retreating ice shelves on other parts of the continent, says Hogg:
“The decrease in ice shelf area in west Antarctica is particularly important as this ice shelf area actively ‘buttresses’ the flow of ice from the ice sheet behind it, which through ice dynamic processes is one of the reasons why west Antarctica is contributing significantly to present-day sea level rise.”
Indeed, the seventh most-talked about paper in 2023 (see below) is a Nature Climate Change study warning that accelerated melt of west Antarctica’s ice shelves is now locked in, even for the most ambitious emissions reduction scenarios. The authors provide this stark conclusion:
“These results suggest that mitigation of greenhouse gases now has limited power to prevent ocean warming that could lead to the collapse of the west Antarctic ice sheet.”
The misleading way the study has been used by some climate-sceptic social media accounts has been “incredibly challenging”, says Hogg, with the authors unable “to reply to every incorrect tweet” about their work. However, they did find “a fair number” of responses from other accounts “saying that they had read the paper and it didn’t provide evidence against climate change”.
This perhaps shows “open access doing its job”, says Hogg, as the paper was published in an open-access journal and so is freely available for anyone to read. In another high-scoring statistic, the full paper has now been viewed more than 150,000 times on the journal’s website.
ExxonMobil
Landing in second place with an Altmetric score of 8,686 is the review paper, “Assessing ExxonMobil’s global warming projections”. Published in Science, the study analyses the global warming projections documented and modelled by scientists at the oil major ExxonMobil between 1977 and 2003.
(There is a higher-scoring paper, “The 2023 state of the climate report: Entering uncharted territory”, in the journal BioScience, but it is a “special report” and was not formally peer reviewed.)
The results indicate that “in private and academic circles since the late 1970s and early 1980s, ExxonMobil predicted global warming correctly and skillfully”, the paper says, adding:
“ExxonMobil’s average projected warming was 0.20C ±0.04C per decade, which is, within uncertainty, the same as that of independent academic and government projections published between 1970 and 2007.”
The findings reveal that ExxonMobil “knew as much as academic and government scientists knew” about global warming decades ago. But, the paper adds, “whereas those scientists worked to communicate what they knew, ExxonMobil worked to deny it”.
The study was covered by 823 news stories by 555 outlets, including BBC News, the Associated Press, CNN, Vice, CNBC and Inside Climate News. It was also included in 48 blog posts and more than 13,000 tweets. It is the 12th most talked-about paper on any topic in 2023.
Extreme heat
In third place is the Nature Medicine paper, “Heat-related mortality in Europe during the summer of 2022”, with a score of 7,821. The study finds that more than 60,000 deaths in the summer of 2022 – Europe’s hottest season on record – were linked to the heat.
Across 35 countries, the highest numbers of heat-related deaths occurred in Italy (18,010 deaths), Spain (11,324) and Germany (8,173), the study says. It also finds that the “burden of heat-related mortality was higher among women”, with 56% more heat-related deaths in women than men, relative to population.
The study was picked up in 943 news stories from more than 650 outlets – the largest number of any paper in the top 25. It was picked up by outlets across Europe, including Sky News and ITV News in the UK, Agence France-Presse in France and Der Spiegel in Germany. Carbon Brief also covered the article in detail.
The widespread coverage was likely to be in part because Europe was experiencing a heatwave dubbed “Cerberus” when the paper was published in July.
Lead author Dr Joan Ballester Claramunt from the Barcelona Institute for Global Health tells Carbon Brief that the paper also “received so much attention from the media because society is increasingly aware of the health risks of environmental factors, and particularly in a context of rapidly warming temperatures”.
Rest of the top 10
In fourth place is, “Warning of a forthcoming collapse of the Atlantic Meridional Overturning Circulation”, which was published in Nature Communications.
The study uses statistical techniques to detect early warning signs of a shutdown in the Atlantic Meridional Overturning Circulation (AMOC), one of the major current systems in the world’s oceans that plays a crucial role in regulating climate.
While assessments using climate model simulations typically suggest that AMOC is “unlikely” to pass a tipping point within the 21st century, the study says a collapse could occur “around mid-century under the current scenario of future emissions”.
(Another paper that also uses observation-based early warning signals to assess the stability of AMOC featured in second place in Carbon Brief’s leaderboard for 2021.)
The paper’s Altmetric score of 6,216 reflects its widespread news coverage, covering 672 stories from more than 500 outlets, including the Washington Post, Politico, El País, CNN and Der Spiegel.
The papers in fifth and ninth place both set out frameworks for assessing “safe” boundaries for the Earth to be a habitable place for humans.
In fifth place with a score of 5,411 is the Science Advances paper, “Earth beyond six of nine planetary boundaries”. Providing the latest assessment of the boundaries that were first established in 2009, the paper warns that “Earth is now well outside of the safe operating space for humanity”.
The ninth-placed paper, “Safe and just Earth system boundaries”, shares a number of the same authors and sets out to quantify limits for “climate, the biosphere, water and nutrient cycles and aerosols at global and subglobal scales”. When the paper was published in May, Carbon Brief reported on the mixed reaction the paper received from other scientists, including concerns that a “self-selected group of scientists” were defining the “safe space” for the planet.
In sixth place is the Science paper, “Global glacier change in the 21st century: Every increase in temperature matters”, which reveals a “strong linear relationship between global mean temperature increase and glacier mass loss”.
The study projects that glaciers outside of Antarctica and Greenland will lose between 26% and 41% of their collective mass by 2100, relative to 2015, under warming of 1.5C to 4C, respectively. Such a loss would cause 49-83% of glaciers to disappear and see 90-154mm added to global sea levels, the study says.
In seventh place is the Nature Climate Change paper, “Unavoidable future increase in West Antarctic ice-shelf melting over the 21st century”, as mentioned above. The findings, the authors say, present a “sobering outlook” for ice shelves in the Amundsen Sea.
The paper made an appearance in the Science round of Carbon Brief’s annual quiz.
The eighth-placed paper is, Quantifying the human cost of global warming, published in Nature Sustainability. It quantifies this cost in terms of the number of people left outside the “climate niche” in which human civilisation has flourished for centuries.
The study shows that climate change has already put around 9% of people outside this niche, and that, by end-of-century, current policies leading to around 2.7C global warming could leave 22-39% of people outside the niche as well.
Finally, rounding out the top 10 is, “Climate extremes likely to drive land mammal extinction during next supercontinent assembly”, in Nature Geoscience.
The study looks at the prospects for humans and other mammals on Earth based on first-ever supercomputer climate modelling of the distant future. The knock-on impacts of all Earth’s continents eventually converging to form the supercontinent “Pangea Ultima” would see huge amounts of CO2 released into the air through volcanic eruptions, it says.
The resulting global temperatures of up to 75C would, as a headline in the i newspaper put it, “one day wipe out humanity – but not for another 250m years”.
Elsewhere in the top 25
The rest of the top 25 includes a mix of research, including a paper on the impacts of El Niño on economic growth, a study on the environmental impacts of different types of diets and analysis of the amount of global warming still “in the pipeline” by former Nasa scientist Dr James Hansen.
In 14th place is the Nature paper, “Assessing the size and uncertainty of remaining carbon budgets”, which presents an updated estimate of the remaining carbon budget for limiting warming to 1.5C and 2C.
In a 2022 Carbon Brief guest post, some of the study authors present a similar analysis, concluding that the remaining carbon budget to limit warming to 1.5C could be just 260bn tonnes of CO2 (GtCO2) – the equivalent of around six years of emissions. They add:
“Cutting global CO2 emissions to zero by 2050, in line with limiting warming to 1.5C, would require them to fall by about 1.4GtCO2 every year, comparable to the drop in 2020 as a result of Covid-19 lockdowns around the world, but this time driven by a long-term, structural change of the economy.
“This highlights that the scale of the challenge is immense, no matter the precise figure of the rapidly shrinking carbon budget.”
Antarctic sea ice made headlines around the world both in 2022 and 2023, by setting two consecutive years of record low sea ice extent. In August 2023, researchers published a sobering study in Communications Earth and Environment under the title, “Record low 2022 Antarctic sea ice led to catastrophic breeding failure of emperor penguins”.
The study finds that melting ice led to widespread “breeding failure” across Antarctic emperor penguin colonies and received widespread media attention. It has been mentioned in 537 news articles, generating headlines such as, “Thousands of penguins die in Antarctic ice breakup”, from BBC News and, “Thousands of penguin chicks killed by early sea ice breakup, study says”, in the Washington Post.
The Guardian, New Scientist and Daily Telegraph were among the other publications that reported on the study. This surge of attention pushed the paper to 15th in the Carbon Brief ranking, with an Altmetric score of 3,551.
Meanwhile, the Lancet Countdown on health and climate change slipped down the rankings this year. After three years in the Carbon Brief’s top 10, this year’s report lands in 20th place with an Altmetric score of 3,191.
The report is an epic annual publication, which reviews vast swathes of literature and has more than 100 authors this year. This year’s report introduced some key new indicators of the links between climate change and human health. It was also the first to include projections on how the indicators might worsen in a warmer world.
The report finds that loss of labour due to heat exposure resulted in a $863bn loss of “potential income” in 2022. The agriculture sector was hit the hardest by the loss of labour, accounting for 82% of losses in least developed countries, the authors add.
Carbon Brief’s coverage of the report highlights this loss of income due to heat stress. The graph below shows effective income losses in 2022 due to heat stress in agriculture (blue) and other sectors (red), as a percentage of GDP, by continent.
One spot below the Lancet report is a Geophysical Research Letters study which warns that climate change is making air turbulence stronger and more frequent. The findings, which were picked up in more than 500 news articles, have worrying implications for aircraft passengers.
Back in 2017, study author Dr Paul Williams wrote a Carbon Brief guest post warning that “the most severe [type of turbulence] – the kind that can launch passengers out of their seats and cause serious injuries – is set to become twice or even three times as common by the latter half of the century”. And a recent Carbon Brief guest post on the fastest jet stream winds – known as “jet streaks” – also forecasts an increase in clear-air turbulence for aircraft passengers.
And in 24th place is the Nature paper, “Glacial lake outburst floods threaten millions globally”, with an Altmetric of 2,991. The study warns that 15 million people globally are exposed to impacts of potential “glacial lake outburst floods” (GLOFs). (For more on GLOFs, see Carbon Brief’s guest post from 2020, which explains how lakes formed by melting glaciers around the world have increased in size by 50% over the past 30 years.)
Top journals
This year there is a clear winner for the journal with the most papers featuring in Carbon Brief’s top 25: Science takes top spot with five papers.
Following Science are the three journals of Nature Climate Change, Nature Communications and the Lancet, each with two papers in the top 25.
For the rest of the top 25, the remaining 14 journals appear once each.
All the final scores for 2023 can be found in this spreadsheet.
Diversity of the top 25
The top 25 climate papers of 2023 cover a huge range of topics and scope. However, despite the variety in the climate research the papers present, analysis of their authors reveals a distinct lack of diversity.
In total, the top 25 climate papers of 2023 have more than 440 authors. Carbon Brief recorded the gender and country of affiliation for each of these authors. (The methodology used was developed by Carbon Brief for analysis presented in a special 2021 series on climate justice.)
The analysis reveals that the authors of the climate papers most featured in the media in 2023 are predominantly men from the global north.
The chart below shows the institutional affiliations of all authors in this analysis, broken down by continent – Europe, North America, Oceania, Asia, South America and Africa.
The analysis shows that nine out of every 10 authors are affiliated with institutions from the global north – defined as North America, Europe and Oceania. Meanwhile, only six authors are from Africa and South America.
Further data analysis shows that there are also inequalities within continents. The map below shows the percentage of authors from each country in the analysis, where dark blue indicates a higher percentage. Countries that are not represented by any authors in the analysis are shown in white.
The top-ranking countries on this map are the UK and the US, which together account for almost half of all authors in this analysis (25% and 18%, respectively).
More than half of all researchers from the global south are from China – which accounts for around 6% of all researchers in the analysis.
Meanwhile, only one-third of authors from the top 25 climate papers of 2022 are women. Similarly, only seven of the 25 papers have a female lead author.
The plot below shows the number of male (purple) and female (orange) authors in this analysis from each continent.
The full spreadsheet showing the results of this data analysis can be found here. For more on the biases in climate publishing, see Carbon Brief’s article on the lack of diversity in climate-science research.

Analysis: The climate papers most featured in the media in 2023
Eric Mackres is senior manager of urban analytics for the WRI Ross Center for Sustainable Cities and attended London Climate Action Week during the June 2026 heatwave. Usama Bilal is an associate professor of epidemiology and co-director of the Urban Health Collaborative at Drexel University.
As thousands gathered in London for one of the year’s largest climate gatherings last week, Western Europe faced its most severe heatwave ever recorded. The irony was not lost.
Across Europe, over a dozen countries issued urgent heat warnings and Spain registered significant deaths. In London, where air conditioning is rare in buildings and on trains and buses, temperatures soared past 36 degrees Celsius (97F) and schools closed early. The mayor announced the city’s first heat action plan – an important step.
Extreme heat is now a public health crisis for many of the world’s cities, as the urban heat island effect intensifies dangerous temperatures – and it’s growing worse. Around 500,000 people die from extreme heat every year. As global temperatures rise, and with a severe El Niño getting underway, even more people will die and be hospitalised unless cities act soon.
But most cities are still taking a far too one-sized-fits-all approach to tackling heat, looking only at temperatures and not its local effects on people and their health.
People experience heat differently
How extreme heat affects people’s health can vary widely across a country and city, depending on their environment and demographics. Cities can save far more lives and prevent more hospitalisations by taking a tailored approach, using data to understand who’s most vulnerable and directing solutions toward them.
The good news: better data now exists that enable cities to pinpoint who’s most at risk. And that data can inform customised adaptation strategies to save lives. Indeed, the future of cities will hinge on their ability to deliver solutions to extreme heat tailored to at-risk people and neighborhoods.
Comment: Climate adaptation in Africa needs investment, not imported solutions
First, cities should start by measuring heat’s risks to people’s health locally. Our work in Brazil and across Latin America shows big differences in what temperatures are dangerous and how quickly risks escalate at higher temperatures. These variations exist between cities, between demographic groups and between neighbourhoods.
But it’s not as simple as finding the hottest places. In temperate Porto Alegre, in southern Brazil, a person’s risk of death increases by 25% at temperatures of 27 degrees Celsius (81F). In tropical Teresina, in northern Brazil, which is hot year-round, the same temperature does not elevate the risk of death. At 32 degrees Celsius (90F), a person’s risk of death increases by a milder 10%.
These differences also exist within cities where the climate is the same. Elderly people, the very young, lower-income communities and those without air-conditioning and shaded green spaces are all more likely to get sick, be hospitalised, or die from heat. Areas with more trees and green spaces usually have lower temperatures, and therefore lower impacts of heat.
Targeted heat alerts
Second, cities can use this data to develop early warning systems and outreach campaigns that give people more targeted heat alerts. Research in the UK found that the elderly, despite being among the most at-risk, often were unable to heed warnings during the 2022 heatwave. Well-designed heat warning systems and city responses strengthen people’s trust in health services. They can change people’s behaviours and better prepare municipal services, helping reduce illness, hospital visits and deaths.
Rio de Janeiro adopted a heat alert system in 2024 with five alert levels based on past heatwaves’ impacts on health and forecasts of when temperature and humidity will hit those dangerous levels again. The alert levels activate services like cooling centres, extra public drinking water, and changes to outdoor events. When a heatwave struck during Carnival in 2025, the city was able to deploy resources to protect and warn people while still allowing events to go on.
WHO issues new guidance on heat-health action plans, as El Niño sets in
Finally, cities should use local heat data to target cooling solutions to where they can help people the most. Solutions like tree cover, shade structures and cool roofs lower temperatures and can provide targeted relief for the most vulnerable people, like outdoor workers and those who travel by foot, bike or public transit.
In Florianópolis, Brazil, we helped the local government use heat impact modeling to design a green corridor and urban forestry project that will reduce pedestrians’ heat stress up to 7 degrees C. In Hermosillo, Mexico, our researchers worked with the city and found that certain neighbourhoods could feel up to 14 degrees C hotter than the shaded city center. A park is now under construction that will bring better shade and heat relief to one of the city’s most at-risk areas.
Connecting health and climate planning
Momentum to address extreme heat in cities is growing, from both national and local governments. At last year’s UN climate summit in Brazil, the Belém Health Action Plan saw 30 national health ministries commit to build climate-resilient health systems based on local data and evidence-based policies.
And over 160 local governments joined the Beat the Heat initiative, committing to develop urban heat action plans and deliver passive cooling projects to reduce health risks.
But there’s still a disconnect between health, urban and climate officials. Only 23% of World Meteorological Organization member countries integrate weather information into health surveillance systems. Heat-health impact models, though increasingly easy to scale, are not yet built for every city. Some cities still need to collect local data for specific demographics and neighbourhoods – and many need support.
National and local governments will need to partner on this tailored approach. It will require integrating local heat and health data into public health systems, city planning, infrastructure, and disaster preparedness.
We have the data to know who will be most impacted by extreme heat when – and the solutions to keep people alive and out of the hospital. It’s time for governments to use them.

With extreme heat now a public health crisis, local data can save lives
As governments gathered at the Our Ocean Conference in Kenya’s coastal city of Mombasa this month, pledging over $6 billion for marine protection, sustainable fisheries and offshore wind, one issue remained largely absent from the main stage: the continued expansion of offshore oil and gas.
From Norway, Brazil and Guyana to South Africa, Angola and Kenya, countries are pushing ahead with offshore oil and gas projects even as they promise to protect marine ecosystems and tackle the climate change that is heating the ocean, raising sea levels and damaging coastal livelihoods.
Governments argue that offshore oil and gas production is needed for energy security, public revenues and economic growth, but environmental groups say new drilling risks locking countries into decades of fossil fuel production just as they are promising to build a sustainable blue economy.
Inia Seruiratu, Fijian parliamentarian and the Pacific COP31 Envoy for the Ocean, said the contradiction is becoming harder to ignore.
“For too long, two conversations – climate mitigation and ocean protection – have run on separate tracks, in separate rooms, with separate experts,” Seruiratu told delegates at a side event during the Mombasa conference held on the shores on the Indian Ocean.

Offshore oil and gas expansion threatens key marine ecosystems, report warns
Sea life in countries like Kenya is under threat from planned new oil and gas production, analysis by environmental groups has found
“We talk about emissions reductions in one hall, and coral bleaching in the other, as if they were unrelated phenomena rather than cause and effect. As we commit to new marine protected areas, new ocean financing and fisheries action, we cannot continue to treat the symptoms while funding the disease,” he added.
In Mombasa, only one side event out of the dozens of panels was dedicated to the threats posed by the expansion of offshore oil and gas. That event was organised by civil society rather than governments.
New wave of offshore projects
One-third of the world’s global production of oil and gas comes from offshore projects. They harm oceans in part through the greenhouse gas emissions generated by the fuels they produce, with climate change already driving record sea temperatures, coral bleaching and sea-level rise.
Offshore exploration and production also affect marine life through seismic surveys, underwater noise, vessel traffic and the risk of oil spills, threatening sensitive habitats such as coral reefs, mangroves and seagrass meadows that support fisheries, biodiversity and coastal protection.
Now, as onshore reserves mature, a new wave of offshore oil and gas development is advancing across the world.
Offshore oil and gas expansion threatens key marine ecosystems, report warns
A May report by Earth Insight found that 85% of all hydrocarbon discoveries made in 2024 were offshore, with new projects advancing from Norway and Brazil to Guyana, Namibia and East Africa.
In Africa, countries such as Namibia, Tanzania and Kenya say exploiting fossil fuel resources could help finance development, support economic growth and lift millions out of poverty, particularly at a time when many face high debt levels and limited access to climate finance.
Kenya’s conundrum
The debate was on display at the Mombasa conference, where host Kenya announced it was joining the Global Offshore Wind Alliance (GOWA), while also defending plans to explore for oil and gas in the Lamu Basin, a biodiverse coastal region.
“The energy transition is a journey. It is not a one-stop shop,” Alex Wachira, principal secretary for Kenya’s Department of Energy, told Climate Home News. “Therefore, we must explore the transition and bring on as many options as possible while exploiting the resources we have. At some point, the entire sector will transition to 100% renewable,” he added.
Wachira said Kenya’s low contribution to global emissions and its continued development needs justify pursuing offshore oil and gas alongside renewables, adding that the country still has “the industrial revolution” to achieve.
“Kenya needs to have a piece of the pie … our emissions today are the least, but we have suffered the most,” said Wachira.
How Shell is still benefiting from offloaded Niger Delta oil assets
The East African nation is seen as a world leader in renewable energy, with about 90% of its electricity generated from geothermal, hydropower, wind and solar.
Omar Elmawi, a Kenyan climate activist and member of the Fossil Free Ocean Initiative, said Kenya should focus on expanding renewable energy, adding that new fossil fuel projects could result in financial losses as countries move to cut planet-heating emissions and shift to cleaner energy.
“We know we cannot have a future dependent on fossil fuels. The rest of the world is talking about how to move beyond them,” Elmawi told Climate Home News.
“If we invest heavily in fossil fuels within our oceans, we’ll end up with stranded assets and a huge debt that taxpayers will have to pay,” he added.
Offshore wind as a solution
Many environmental groups argue that offshore wind is a promising alternative, as it can deliver similar economic benefits from energy production without worsening climate change.
A study unveiled at the Mombasa conference by Zero Carbon Analytics, Ocean Conservancy and GOWA found that Africa’s offshore wind potential is vast, yet largely untapped.
The continent could install around 6,750 gigawatts of offshore wind capacity – roughly 28 times its current power generation capacity.
Developing just 5% of that potential could create an estimated 5.9 million jobs and generate more than $1 trillion in economic benefits, while producing enough electricity to meet all projected growth in power demand through 2040, the study found.
Campaigners say this could strengthen energy security, reduce dependence on imported fossil fuels and help build new industries around ports, manufacturing and maritime services.
According to a 2025 World Bank report, every $1 million invested in offshore wind creates around 25 jobs – five times more than fossil fuels.
Robust marine protection needed
Bruna Campos, senior campaigner for the Climate and Energy Program at the Center for International Environmental Law (CIEL), said offshore wind offers a cleaner alternative to offshore oil and gas, but warned that poorly planned projects can also cause harm.
She called for robust marine spatial planning, environmental assessments and early community involvement to ensure the industry does not repeat mistakes associated with fossil fuel development.
“You need to understand what are the impacts that offshore wind will have on sensitive ecosystems and communities,” Campos told Climate Home News.
West African nations target Eastern Atlantic for early high seas protection
A 2024 UN study found that offshore wind farms can disturb whales, seals, porpoises and migratory fish, particularly during construction, when underwater noise and seabed disruption are greatest. At the same time, turbine foundations can act as artificial reefs, creating habitat for some species and boosting local fish populations.
Pacific COP31 Envoy for the Ocean Seruiratu said that while investing in renewables is crucial, it is also important to keep pushing for fossil fuels to be phased out.
He said his own country, Fiji, is among a growing block of nations calling for “a binding international mechanism for an orderly and equitable phase-out of fossil fuels”.
“Every offshore drilling decision, every new exploration site, every delayed phase-out is a decision made against the common good,” he added.

Ocean summit stays silent on new wave of offshore oil and gas expansion
Governments are holding “critical” talks this week on a global treaty to curb plastic pollution, as some countries and activists warn that key issues – including measures to rein in soaring plastic production – are being sidelined.
Diplomats are meeting in person in Nairobi for the first time since negotiations were suspended in chaos nearly a year ago, stymied by a long-running deadlock that pits petrostates against more ambitious nations over the reach of the UN pact.
Because nearly all plastic is made from planet-heating oil, gas and coal, the sector’s trajectory will have a major influence on global efforts to cut greenhouse gas emissions.
The four-day informal gathering, which begins on Tuesday, has been billed by the chair of the talks, Chilean ambassador Julio Cordano, as a “brainstorming” session in which countries are invited to put forward possible solutions to some of the treaty negotiations’ most divisive elements.
Cordano is expected to distill those views in a new document intended to serve as the basis for a new draft text of the future treaty, which governments would take up at the next official round of negotiations, scheduled for March 13-24, 2027.
Two earlier rounds, each billed as the final one, ended without agreement, derailed largely by a standoff over how the treaty should address plastic production, which the UN says is set to triple by 2060 without intervention.
Production curbs in the spotlight
Large fossil fuel and petrochemical producers, led by Saudi Arabia, the United States, Russia and India, have repeatedly argued that the treaty should focus only on managing plastic waste. A US State Department spokesperson told Climate Home News that Washington supports “practical, cost-effective solutions” to plastic pollution, while opposing “global plastic bans”.
A majority of countries – including most European, Latin American, African and Pacific island nations -want to limit the manufacturing of plastic to “sustainable levels”, but have not pushed for any wide-ranging ban.

The chair of the negotiations proposes informal meetings through 2026 to bridge deep divisions among countries, following the collapse of talks in Geneva last year
Ahead of what it described as “critical” talks in Nairobi, the French government said last week it had already shown flexibility and “significantly scaled back” its initial ambitions. But a French official told a meeting of EU environment ministers that without an explicit reference to the “unsustainable nature” of plastic production, the treaty would be “fundamentally unbalanced, ineffective and, worse still, could set us on the wrong path for decades to come”.
In a separate written communication, the French government lamented that informal meetings held in recent months have given “disproportionate visibility to the positions of the least ambitious states”, fuelling a “risk that partial agreements may be reached only on the issues with the broadest consensus”.
Dennis Clare, a negotiator for the Pacific island nation of Micronesia, told Climate Home News that “if we fail to address any key elements”, including overproduction, the impacts of the plastic crisis on the climate, human health and ecosystems will only grow more severe.
Fears over “political calculations”
Despite such concerns, plastics production is not mentioned in the wide-ranging list of topics Cordano has drafted for the meeting – an omission that has alarmed observers.
Christina Dixon, a campaigner at the Environmental Investigation Agency (EIA), said there appeared to be an attempt to write off this crucial element of the treaty as “too complicated and politically unviable”.
David Azoulay, environmental health programme director at the Center for International Environmental Law (CIEL), said the meeting’s proposed structure was “highly concerning”. He accused the chair of “making political calculations in favour of potential short-term wins” and aiming to deliver a treaty “based on the lowest common denominator”.
Speaking to journalists last week, Cordano pushed back, insisting that “no topic is off the table” and inviting countries to bring whatever proposals they judged necessary for a successful outcome.
He added that the treaty could not be allowed to settle for just any level of ambition, and that he would not be happy with an outcome at all costs.
“This is what makes it so difficult and complex,” said Cordano, who was elected in February after his predecessor’s resignation. Countries “are trying to be creative” in finding solutions, he explained, because “the road to the objective of our work might not be so obvious”.
