The Intergovernmental Panel on Climate Change’s forthcoming special report on climate change and cities has more women than men on its authorship team, for the first time in the organisation’s history, Carbon Brief analysis shows.
The IPCC released a list earlier this month of the 97 authors (pdf) who will write the cities report – which is scheduled for publication in March 2027.
With 46 men and 51 women, it is the first report in the IPCC’s 37-year history to have more women than men as authors.
Meanwhile, with 39 authors from institutions in the global south and 58 from the global north, this report has the fifth-highest representation of authors from the global south.
The report is one of the multiple documents, including special reports, working group reports and methodology reports, that will make up the IPCC’s seventh assessment cycle (AR7).
Last year, Carbon Brief published an in-depth analysis of the gender and country of affiliation of the authors of major IPCC reports, from the first assessment report in 1990 to the sixth assessment report in 2023.
The analysis has now been expanded to include all reports published since 1990 by the IPCC, including assessment reports, special reports and methodology reports.
It shows a steady increase in the proportion of women and scientists from global-south institutions contributing to the IPCC reports, but highlights that these groups are still underrepresented.
Gender balance
Carbon Brief has analysed the coordinating lead authors, lead authors and review editors who have worked together to produce dozens of IPCC reports.
The chart below shows the gender balance of the authors of all IPCC reports ever published.
Each IPCC assessment cycle is marked by the publication of three working-group reports, which are summarised in a synthesis report. Carbon Brief has grouped these four reports under the headline “assessment reports” for every assessment cycle.
The first, second and third assessment reports are indicated by the acronyms FAR, SAR and TAR. Subsequent assessment reports are indicated by AR, followed by the name of the assessment cycle.
Most assessment cycles also saw the publication of “special reports”, focusing on specific areas of climate change, and “methodology reports” – technical documents that focus on specific areas of the IPCC’s methodology. Acronyms for these reports are given as SR and MR, respectively, followed by the name of the assessment cycle.
For example, the special reports on 1.5C, the ocean and cryosphere and climate change and land – published over 2018-19 – are part of the sixth assessment cycle and are referred to collectively as SR6.
To assign each special and methodology report to an assessment cycle, Carbon Brief assumes that assessment reports are the last documents to be published in each assessment cycle. Carbon Brief has grouped the authors from special reports (“SR”) and methodology reports (“MR”) separately for each assessment cycle.
The analysis shows that when the IPCC’s first-ever assessment report was published in 1990, only 8% of authors were women. The representation of women in the IPCC has steadily risen over time and by the sixth assessment cycle (2018-22) more than one-third of authors were women.
The special report on climate change and cities is the only output from the seventh assessment cycle with a publicly available authorship list to date. With 46 men and 51 women, the IPCC cities report is the first in the organisation’s history to have more women than men on its author list.
The IPCC’s seventh assessment cycle – which will include the three main working group reports, one special report and two methodology reports – is likely to have hundreds of authors. The authorship teams for the other reports have not yet been selected.
The graphic below shows a more detailed view. Each dot represents one person – with women shown in orange and men in purple. Where one author contributed to multiple working group reports in the same assessment cycle, these repeats have been removed. Grey dots indicate that the gender of the author could not be determined.
For more information on why gender representation is important in climate science, read Carbon Brief’s 2021 analysis on the lack of diversity in climate science.
Global-south representation
Carbon Brief also analysed how the proportion of IPCC authors from institutions in the global south has changed.
Here, “global south” is defined as countries in Africa, Asia (excluding Japan), Latin America and Oceania (excluding Australia and New Zealand). “Global north” is defined as countries in North America and Europe, as well as Australia, New Zealand and Japan.
The chart below shows the percentage of authors from the global south in every IPCC report.
When the IPCC published its first assessment report, only 11% of authors were from institutions in the global south. This percentage has risen over the years, reaching 38% in the sixth assessment reports, the analysis shows.
With 58 authors from institutions in the global north and 39 from the global south, the IPCC’s cities report is the organisation’s fifth-most global south-dominated report.
(The highest-ranking report for global-south authorship, with 53 authors from the global north and 54 from the global south, was the special report on climate change and land. Published in 2019, this was part of the sixth assessment cycle.)
The graphic below shows a more detailed representation of IPCC authors from institutions in the global north and south. Each dot represents one person – with experts from global-south countries shown in dark blue and global-north countries in light blue. Where one author contributed to multiple working group reports in the same assessment cycle, these repeats have been removed.
The upcoming cities report includes authors from institutions in 54 different countries. The most highly represented countries are Japan, the Netherlands, the UK and the US, with six authors each.
The map below shows the number of authors from institutions in each country, across all IPCC reports included in this analysis. The map on the top shows countries in the global north while the map on the bottom shows those in the global south. Darker colours indicate more authors.
Every author in the cities report has two countries listed next to their name, labelled “country” and “citizenship”. Carbon Brief used the former – which indicates the country where the scientist works – for the analysis above, because citizenship data is not available in earlier reports.
However, IPCC scientists previously told Carbon Brief that, sometimes, experts from the global south find it easier to apply to join the IPCC via institutions in the global north.
An analysis of the citizenship of authors of the IPCC cities report finds that 51 are from global-south countries. However, only 39 are affiliated with institutions in the global south.
Methodology
Carbon Brief obtained data used in this analysis from a range of sources, including the IPCC website, the IPCC’s technical support unit and analysis by Carbon Brief staff.
(The “methodology” section of Carbon Brief’s 2023 analysis on IPCC authorship contains more details on how Carbon Brief collected authorship data from the main working group reports and recent special reports.)
Carbon Brief downloaded authorship data on the AR7 special report on climate change and cities from the IPCC website, which lists data on each author’s gender, citizenship and the country where their institution was based.
For authorship data on all the methodology reports and the special reports published before the fifth assessment cycle, Carbon Brief manually extracted information from the report pdfs, which were accessed on the IPCC archive.
In many early reports, only the initials were given for authors’ first names. In these instances, Carbon Brief used internet searches or a ChatGPT-based tool to find first names. If ChatGPT provided a name, Carbon Brief double-checked its accuracy with internet searches.
Similarly, Carbon Brief used internet searches and ChatGPT to suggest the most likely gender of the authors based on the information available. In some instances, it was not possible to find the authors’ first name or gender and so gender was recorded as “unknown” in the analysis.
Carbon Brief recognises that gender is not best categorised using a binary “male” or “female” label and appreciates that the methods used of determining author gender could result in inaccuracies. However, for the purpose of this analysis, this method was deemed suitable.
As many results were recorded manually, or with the use of artificial intelligence, Carbon Brief acknowledges the possibility of human error. Authorship data collected from earlier reports are more likely to contain these errors. However, the large sample size of more than 5,600 authors in total may mitigate the effect of any such inaccuracies on the overall trends identified.

Rudecindo Espíndola’s family has been growing corn, figs and other crops for generations in the Soncor Valley in northern Chile, an oasis of green orchards in one of the driest places on Earth – the Atacama desert.
Perched nearly 2,500 metres above sea level, his village, Toconao, means “lost corner” in the Kunza language of the Indigenous people who have lived and farmed the land in this remote spot for millennia.
“Our deep connection to this place is based on what we have inherited from our ancestors: our culture, our language,” said Espíndola, a member of a local research team that found evidence that people have inhabited the desert for more than 12,000 years.
This distant outpost is at the heart of the global rush for lithium, a silvery-white metal used to make batteries for electric vehicles (EV) and renewable energy storage that are vital to the world’s clean energy transition. The Atacama salt flat is home to about 25% of the world’s known lithium reserves, turning Chile into the world’s second-largest lithium producer after Australia.
For decades, the Atacama’s Indigenous Lickanantay people have protested against the expansion of the lithium industry, warning that the large evaporation ponds used to extract lithium from the brine beneath the salt flats are depleting scarce and sacred water supplies and destroying fragile desert ecosystems.
Espíndola joined the protests, fearing that competition for water could pose an existential threat to his community.
But last year, he was among dozens of Indigenous representatives who sat across the table from executives representing two Chilean mining giants to hammer out a governance model that gives Indigenous communities living close to lithium sites a bigger say over operations, and a greater share of the economic benefits.
A pioneering deal
The agreement is part of a landmark deal between state-owned copper miner Codelco and lithium producer the Sociedad Química y Minera de Chile (SQM) to extract lithium from the salt flats until 2060 through a joint venture called NovaAndino Litio.
The governance model that promises people living in Toconao and other villages around the salt flats millions of dollars in benefits and greater environmental oversight is the first of its kind in mineral-rich Chile, and has been hailed by industry experts as the start of a potential model for more responsible mining for energy transition metals.
NovaAndino told Climate Home News the negotiations with local communities represented an “unprecedented process that has allowed us to incorporate the territory’s vision early in the project’s design” and creates “a system of permanent engagement” with local communities.
The company added it will contribute to sustainable development in the area and help “the safeguarding of [the Lickanantay people’s] culture and environmental values”.

For mining companies, such agreements could help reduce social conflicts and protests, which have delayed and stalled extraction in other parts of South America’s lithium-rich region, known as the lithium triangle.
“Argentina and Bolivia could learn a lot from what we’re doing [here],” said Rodrigo Guerrero, a researcher at the Santiago-based Espacio Público think-tank, adding that adopting participatory frameworks early on could prevent them from “going through the entire cycle of disputes” that Chile has experienced.
Justice at last?
As part of the governance deal, NovaAndino has pledged to adopt technologies that will reduce water use and mitigate the environmental impacts of lithium extraction.
It has also committed to hold more than 100 annual meetings with community representatives to build a “good faith” relationship, and an Indigenous Advisory Council will meet twice a year with the company’s sustainability committee to discuss its environmental strategy, company sources said. The meetings are due to begin next month.
To oversee the agreement’s implementation, an assembly – composed of representatives from all 25 signatory communities – will track the project’s progress. In addition, NovaAndino will hold one-on-one meetings with each community to address issues such as the hiring of local people and the protection of Indigenous employees.
Espíndola said the deal, while far from perfect, was an important step forward.
“Previously, Indigenous participation was ambiguous. Now we talk about participation at [every] hierarchical level of this process, a very strong empowerment for Indigenous communities,” said Espíndola, adding that it did not give local communities everything they had asked for. For instance, they will not hold veto power over NovaAndino’s decisions or have a formal shareholder role.
But after years of conflict with mining companies, a form of “participatory justice is being done”, he said.
Not everyone is convinced that the accord, pushed by Chile’s former leftist government, marks progress, however.
“Not in our name”
The negotiations have caused deep divisions among the Lickanantay, some of whom say greater engagement with mining companies will not stop irreparable damage to the salt flats on which their traditional way of life depends. Others fear the promise of more money will further erode community bonds.
In January 2024, Indigenous communities from five villages closest to the mining operations, including Toconao, blocked the main access roads to the lithium extraction sites. They said the Council of Atacameño Peoples, which represents 18 Lickanantay communities and was leading discussions with the company, no longer spoke for them.
Official transcripts of consultations on the extension of the lithium contracts and how to share the promised benefits reveal deep divisions. Tensions peaked when communities around the mining operations clashed over how to distribute the multimillion-dollar windfall, with villages closest to the mining sites demanding the largest share.
Eventually, separate deals establishing a new governance framework over mining activities were reached between Codelco and SQM with 25 local communities, including a specific agreement for the five villages closest to the extraction sites.
The division caused by the separate deal for the five villages “will cause historic damage” to the unity of the Atacama desert’s Indigenous peoples, said Hugo Flores, president of the Council of Atacameño Associations, a separate group representing farmers, herders and local workers who oppose the mining expansion.
Sonia Ramos, 83, a renowned Lickanantay healer and well-known anti-mining activist, lamented the fracturing of social bonds over money, and for the sake of meeting government objectives.
“There is fragmentation among the communities themselves. Everything has transformed into disequilibrium,” said the 83-year-old.
“[NovaAndino] supposedly has economic significance for the country, but for us, it is the opposite,” she said.
The company told Climate Home News it has “acted consistently” to promote “transparent, voluntary, and good-faith dialogue with the communities in the territory, recognising their diversity and autonomy, and always respecting their timelines and forms of participation”.
A one-off deal or a model for others?
The NovaAndino joint venture is a pillar of Chile’s strategy to double lithium production by 2031 and consolidate the copper-producing nation’s role in the clean energy transition as demand for battery minerals accelerates.
Chile’s new far-right president, José Antonio Kast, who was sworn in last week, promised to respect the lithium contracts signed by his predecessor’s administration – including the governance model.
Still, some experts say the splits over the new model highlight the need for legislation that mandates direct engagement and minimum community benefits for all large mining projects.
“In the past, this has lent itself to clientelism, communities who negotiate best or arrive first get the better deal,” said Pedro Zapata, a programme officer in Chile for the Natural Resource Governance Institute.
“This can be to the detriment of other communities with less strength. We cannot have first- and second-class citizens subject to the same industry,” he added.
The government is already negotiating two more public-private partnerships to extract lithium with mining giant Rio Tinto, which it said would include a framework to engage with Indigenous communities and share some of the revenues. The details will need to be negotiated between local people, the government and the company.
Sharing the benefits of mining
Under the deal in the Atacama, NovaAndino will run SQM’s current lithium concessions until they expire in 2030 before seeking new permits to expand mining in the region under a vast project known as “Salar Futuro” – a process which will require further mandatory consultations with communities.
Besides the participatory mechanism, the new agreement promises more money than ever before for salt flat communities.
Depending on the global price of lithium and their proximity to the mining operations, Indigenous communities could collectively receive roughly $30 million annually in funding – about double what SQM currently disburses under existing contracts.
When taking into account the company’s payments to local and regional authorities, contributions could reach $150 million annually, according to the government.
To access these resources, each community will need to submit a pipeline of projects they would like funding for under a complex arrangement that includes five separate financial streams:
- A general investment fund will distribute funding based on each village’s size and proximity to the mining sites
- A development fund will support projects specifically in the five communities closest to the extraction sites
- Contributions to farmers and livestock associations
- Contributions to local governments
- A groundbreaking “intergenerational fund” held in trust for the Lickanantay until 2060
For many isolated communities in the Atacama desert, financial contributions from mining firms have funded essential public services, such as healthcare and facilities like football pitches and swimming pools.
In the past, communities have used some of the benefits they received from mining to build their own environmental monitoring units, hiring teams of hydrogeologists and lawyers to scrutinise miners’ activities.
Espíndola said the new model could pave the way for more ambitious development projects such as water treatment plants and community solar energy projects.
Competition for water
The depletion of water resources is one of local people’s biggest environmental concerns.
To extract lithium from the salt flats, miners pump lithium-rich brine accumulated over millions of years in underground reservoirs into gigantic pools, where the water is left to evaporate under the sun and leaves behind lithium carbonate.
One study has shown that the practice is causing the salt flat to sink by up to two centimetres a year. SQM recently said its current operations consume approximately 11,500 to 12,500 litres of industrial freshwater for every metric ton of lithium produced.
NovaAndino has committed to significantly reduce the company’s water use by returning at least 30% of the water it extracts from the brine and eliminating the use of all freshwater in its operations within five years of obtaining an environmental permit.

Lithium tug of war: the US-China rivalry for Argentina’s white gold
As global competition hots up to secure lithium supplies for batteries, China is boosting its investments in Argentina while the US courts President Javier Milei
Cristina Dorador, a microbiologist at the University of Antofagasta, told Climate Home News that reinjecting the water underground is untested at a large scale and could impact the chemical composition of the salt flats.
Continuing to extract lithium from the flats until 2060 could be the “final blow” for this fragile ecosystem, she said.
Asked to comment on such concerns, NovaAndino said any new technology will be “subject to the highest regulatory standards”, and pledged to ensure transparency through “an updated monitoring system with the participation of Indigenous communities”.
High price for hard-won gains
For the five communities living on the doorstep of the lithium pools, one of the biggest gains is being granted physical access to the mining sites to monitor the lithium extraction and its impact on the salt flats.
That is a first and will strengthen communities’ ability to call out environmental harms, said Sergio Cubillos, the community president of Peine, the village closest to the evaporation ponds. It could also give them the means to seek remediation through the courts if necessary, Espíndola said.
Gaining such rights represents long-overdue progress, Cubillos said, but it has come at a high price for the Lickanantay people.
“Communities receiving money today is what has ultimately led to this division, because we haven’t been able to figure out what we want, how we want it, and how we envision our future as a people,” he said.

Landmark deal to share Chile’s lithium windfall fractures Indigenous communities
Diplomats will hold a series of informal meetings this year in a bid to revive stalled talks over a global treaty to curb plastic pollution, before aiming to reconvene for the next round of official negotiations at the end of 2026 or early 2027.
Hoping to find a long-awaited breakthrough in the deeply divided UN process, the chair of the talks, Chilean ambassador Julio Cordano, released a roadmap on Monday to inject momentum into the discussions after negotiations collapsed at a chaotic session in Geneva last August.
Cordano wrote in a letter that countries would meet in Nairobi from June 30 to July 3 for informal discussions to review all the components of the negotiations, including thorny issues such as efforts to limit soaring plastic production.

Why we couldn’t agree on a plastics treaty in Geneva – and what might happen next
Switzerland’s lead negotiator at INC-5.2 reflects on why the talks didn’t succeed – and the options now for getting an effective agreement
The gathering should result in the drafting of a new document laying the foundations of a future treaty text with options on elements with divergent views, but “no surprises” such as new ideas or compromise proposals. This plan aims to address the fact that countries left Geneva without a draft text to work on – something Cordano called a “significant limitation” in his letter.
“Predictable pathway”
The meeting in the Kenyan capital will follow a series of virtual consultations every four to six weeks, where heads of country delegations will exchange views on specific topics. A second in-person meeting aimed at finding solutions might take place in early October, depending on the availability of funding.
Cordano said the roadmap should offer “a predictable pathway” in the lead-up to the next formal negotiating session, which is expected to take place over 10 days at the end of 2026 or early 2027. A host country has yet to be selected, but Climate Home News understands that Brazil, Azerbaijan or Kenya – the home of the UN Environment Programme – have been put forward as options.
Countries have twice failed to agree on a global plastics treaty at what were meant to be final rounds of negotiations in December 2024 and August 2025.
Divisions on plastic production
One of the most divisive elements of the discussions remains what the pact should do about plastic production, which, according to the UN, is set to triple by 2060 without intervention.
A majority, which includes most European, Latin American, African and Pacific island nations, wants to limit the manufacturing of plastic to “sustainable levels”. But large fossil fuel and petrochemical producers, led by Saudi Arabia, the United States, Russia and India, say the treaty should only focus on managing plastic waste.
As nearly all plastic is made from planet-heating oil, gas and coal, the sector’s trajectory will have a significant impact on global efforts to reduce greenhouse gas emissions.
Countries still far apart
After an eight-month hiatus, informal discussions restarted in early March at an informal meeting of about 20 countries hosted by Japan.
A participant told Climate Home News that, while the gathering had been helpful to test ideas, progress remained “challenging”, with national stances largely unchanged.
The source added that countries would need to achieve a significant shift in positions in the coming months to make reconvening formal negotiations worthwhile.
Deep divisions persist as plastics treaty talks restart at informal meeting
Jacob Kean-Hammerson, global plastics policy lead at Greenpeace USA, said the new roadmap offers an opportunity for countries to “defend and protect the most critical provisions on the table”.
He said that the document expected after the Nairobi meeting “must include and revisit proposals backed by a large number of countries, especially on plastic production, that have previously been disregarded”.
“These measures are essential to addressing the crisis at its source and must be reinstated as a key part of the negotiations,” he added.
