LIMA, Oct 30 – The member governments of the Intergovernmental Panel on Climate Change (IPCC) agreed on the scientific content of the 2027 Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage at the Panel’s 63rd Plenary session, which closed this evening in Lima, Peru.
This is one of two methodology reports of the seventh assessment cycle. Carbon Dioxide Removal refers to anthropogenic activities that remove CO2 from the atmosphere and store it durably in geological reservoirs or in products.
The decision opens the next important stage in the report production in which member governments, observer organizations, and IPCC Bureau members will nominate experts to serve as authors.
With this decision, the entire scientific content of all planned reports for the seventh assessment cycle has been agreed upon, clearing the way for their production.
The Panel also agreed on the 2026 workplan for the three Working Group contributions to the Seventh Assessment Report (AR7). The Panel invited the three Working Groups to continue their work by convening Lead Author meetings and other activities planned and budgeted for 2026. The work on the three Working Group contributions to the Seventh Assessment Report will kick off in Paris already in December this year with the first-ever joint Lead Author meeting.
“Panel’s decisions in Lima give strong impetus to our work on our methodology reports and ensure the continuity of IPCC scientific activities and operations related to the production of the three Working Group contributions to the Seventh Assessment Report,” said IPCC Chair Jim Skea.
The three Working Group contributions assess the physical science basis of climate change; impacts, adaptation and vulnerability; and mitigation of climate change.
The Panel also approved IPCC’s overall budget for 2026.

Notes for Editors
What is the IPCC?
The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.
Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, scientists and experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.
The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.
IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.
About the Seventh Assessment Cycle
Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Task Force Bureaus at the IPCC’s Plenary Session in Nairobi.
At its first Plenary Session in the seventh assessment cycle – the 60th Plenary Session in Istanbul, Türkiye, in January 2024 – the Panel agreed to produce in this cycle the three Working Group contributions to the Seventh Assessment Report (AR7), namely the Working Group I report on the Physical Science Basis, the Working Group II report on Impacts, Adaptation and Vulnerability and the Working Group III report on Mitigation of Climate Change. The Synthesis Report of the Seventh Assessment Report will be produced after the completion of the Working Group reports and released by late 2029.
The Panel decided already during the previous cycle to produce a Special Report on Climate Change and Cities and a Methodology Report on Short-lived Climate Forcers during AR7.. Scientists have also been asked to deliver a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage. At the IPCC’s 61st Plenary Session held in Sofia, Bulgaria, from 27 July to 2 August 2024, the Panel agreed upon the outlines for the Special Report on Climate Change and Cities scheduled for approval and publication in March 2027 and for the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers scheduled for publication in the second half 2027. The Panel agreed on the outlines of the Working Group contributions to the Seventh Assessment Report during its 62nd Session in February 2025 held in in Hangzhou, China.
In addition, a revision of the 1994 IPCC Technical Guidelines on impacts and adaptation as well as adaptation indicators, metrics and guidelines, will be developed in conjunction with the Working Group II report and published as a separate product.
IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provided direct scientific input to the First Global Stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.
The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distils and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.
The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the Ocean and Cryosphere in a Changing Climate (September 2019).

LIMA, PERU, Oct 27 – The Intergovernmental Panel on Climate Change (IPCC) today opened its 63rd Plenary Session in Lima, Peru, bringing together some 300 delegates from IPCC member governments and observer organizations to advance its work in the seventh assessment cycle.
Over the four-day session, the Panel will continue discussions on the timelines for the three Working Group contributions to the Seventh Assessment Report (AR7), as well as on the draft outline and timeline of the Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage.
In addition, the Panel will discuss the IPCC’s Trust Fund programme and budget for 2026, the indicative budget for 2027 and 2028, a proposal for an expert meeting, and other agenda items.
“By now, we know the scope of the Seventh Assessment Report, and we have selected the scientists who will be delivering the work,” said IPCC Chair Jim Skea. “Building on the progress made so far, the Panel now needs to settle the important matter of the timelines for producing the reports, taking into account inclusive assessment practices and policy relevance. I trust that Panel members will seek consensus on the timelines in line with the IPCC’s established procedures.”
The Peruvian Minister of Foreign Affairs Hugo de Zela addressed the opening of the IPCC’s 63rd Plenary Session, reaffirming the country’s commitment to the global fight against climate change. In his remarks, Minister De Zela urged member states to act with a sense of urgency and responsibility to finalize the reports and methodologies necessary to accelerate climate action.
“Information produced by the IPCC remains essential to guiding the policy decisions of States seeking to reduce global warming,” said Minister De Zela.
The IPCC’s seventh assessment cycle formally began in July 2023 and will culminate in the release of the AR7 Synthesis Report in 2029. In this cycle, the IPCC will prepare the AR7, which comprises three Working Group contributions and a Synthesis Report, as well as update the 1994 Technical Guidelines for Assessing Climate Change Impact and Adaptation. The Panel will also produce a Special Report on Climate Change and Cities, and two Methodology Reports.

Check against delivery
Your Excellency, Minister of Foreign Affairs, Ambassador Hugo de Zela,
Deputy Minister of Strategic Development of Natural Resources at the Ministry of Environment, Ms Raquel Hilianova Soto Torres,
Director of Climate Change Division of the UN Environment Programme, Martin Krause,
Distinguished delegates, dear colleagues, ladies and gentlemen,
Welcome to the sixty-third plenary session of the Intergovernmental Panel on Climate Change – the IPCC.
Allow me first to greet government delegations, representatives of observer organisations and members of the IPCC Bureau.
As the IPCC Chair, I wish to thank our hosts – the Peruvian government and the city of Lima – for their hospitality and excellent organisation. I know that they have made extraordinary efforts to show their hospitality and welcome us here in not the easiest circumstances.
Our host is a country of ancient civilisation – the Inca people. We have much to learn from cultures that came before us. The structures at Machu Picchu stand as a testament to the Incas’ engineering prowess, with structures built to last and designed to be earthquake-resistant. They practised disaster risk reduction before the term was invented.
This brings me to why we are in Lima this week. More than two years into the seventh assessment cycle, this is our fourth Plenary session. Input from the elected Bureau has been instrumental work in guiding the Panel and ensuring steady progress.
The expert review of the First Order Draft of the Special Report on Cities and Climate Change began ten days ago and will run until mid-December. The second Lead Author meeting for the Methodology Report on Short-Lived Climate Forcers took place less than two weeks ago, and authors are now working on the First Order Draft.
The Panel’s February decision on the scientific content of the three Working Group contributions to the Seventh Assessment Report enabled us to invite nominations of experts to serve as authors. The Bureau concluded its selection in July, and by the end of August, we had appointed 664 authors from more than 100 countries. Among them are seven Peruvian scientists working on the Special Report on Climate Change and Cities and the three Working Groups’ reports. With nominations exceeding available places by a factor of almost six, this speaks to the high quality of the Peruvian nominations.
During these 24 months of the cycle, significant progress has been made on expanded access to scientific literature for authors from developing countries, on a successful Expert Meeting on Gender, Diversity and Inclusion, and on securing support for Chapter Scientists from developing countries. These efforts reflect a growing commitment to inclusivity, diversity and equity across IPCC.
Ladies and gentlemen,
By now, we know the scope of scientific knowledge we need to assess for the Seventh Assessment Report, and who will be delivering the work.
The missing piece is a Panel decision setting out the workplans for the three Working Group reports. This is one of the priority agenda items this week.
Our work for this week also includes completing the outline of the Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilisation and Storage. Agreement on the outline is essential if we are to move forward promptly with this report.
Before I close, allow me to thank our member governments for their scientific and financial support. Our delivery of the most up-to-date, rigorously reviewed, best available science relies on voluntary financial contributions from our member governments.
I invite all member governments to offer support for the vitally important work that the Panel has agreed upon for this cycle. The IPCC Trust Fund is the main mechanism supporting participation from developing country governments and scientists.
Every contribution to the IPCC Trust Fund is important and appreciated. But predictable, multi-year funding commitments are especially valuable. They are vital for securing a sustainable and inclusive basis for IPCC’s current and future work.
Your voluntary contributions ensure the scientific integrity and continuity of the IPCC as the most authoritative and policy-relevant voice on climate science globally.
Thank you.

Prof. Dr. Sonia Isabelle Seneviratne, Vice-Chair of the IPCC Working Group I and a professor at ETH Zürich, is this year’s co-laureate of the prestigious German Environmental Award presented by the German Federal Environmental Foundation (DBU). The DBU award is among the most notable in Europe and comes with a €500,000 purse, which this year will be split with the other co-laureate – the management duo Lars Baumgürtel and Birgitt Bendiek being awarded for circular business model.
This year’s DBU award is bestowed upon Prof. Seneviratne for her “excellent innovative climate research”. In the citation, the DBU Secretary-General Alexander Bonde describes Prof. Seneviratne as a “brilliant climate scientist,” who has used new research methods such as satellite image analysis and “groundbreaking studies on land-climate dynamics to highlight the interactions between soil moisture, vegetation, evaporation and the atmosphere in international discourse.”
The German Environmental Award also recognises Seneviratne’s “outstanding climate protection communication”, her work with the Intergovernmental Panel on Climate Change (IPCC) and the establishment of the Swiss National Drought Platform.
Since 2007, Seneviratne has been a Professor at the Institute of Atmospheric and Climate Science at ETH Zürich. She studied environmental physics and biology at ETH Zürich and the University of Lausanne. She obtained her PhD in 2003 at ETH Zürich and was a postdoctoral scientist at NASA/Goddard Space Flight Centre from 2003 to 2004. Her research addresses climate change and extreme events, land-climate interactions, and terrestrial water processes.
In her work with the IPCC she has been a Coordinating Lead Author and Lead Author on several IPCC reports, including the 2012 Special Report on Extreme events, the 2018 Special Report on 1.5°C Global warming, and the 2021 Working Group I contribution to the Sixth Assessment Report on which she was a Coordinating Lead Author of the Weather and Climate Extremes chapter. In the current seventh assessment cycle, Prof. Seneviratne has been elected as one of the Vice-Chairs of Working Group I, assessing the physical science basis of climate change.
The DBU German Environmental Award, which, this year, will be presented for the 33rd time, honours the achievements of people who make an exemplary contribution to protecting and preserving the environment.
The award ceremony will take place on Sunday, October 26, in Chemnitz, Germany, in the presence of the Federal President of the Federal Republic of Germany Frank-Walter Steinmeier.
GENEVA, September 17 – The Intergovernmental Panel on Climate Change (IPCC) opened today the registration for experts to serve as Expert Reviewers on the First-Order Draft (FOD) of the Special Report on Climate Change and Cities.
Following the Second Lead Author Meeting this August, authors of this Special Report have prepared a first draft, which will be open in a month for experts worldwide to review and provide comments.
The review of the First Order Draft is the first of multiple review stages foreseen for every IPCC report. The review process is critical in preparing IPCC reports, as it helps ensure scientific rigour, the widest range of perspectives, and relevance to the urgent challenges urban areas and communities face in a warming world and changing climate.
Scheduled for release in March 2027, the Special Report on Climate Change and Cities will be the first IPCC report published in the seventh assessment cycle. It is also the only special report in the current cycle. The report aims to provide a timely assessment of the latest science related to climate change and cities, including climate impacts and risks, as well as adaptation and mitigation options.
This review is the first opportunity for experts to engage with the draft text of the Special Report. All review comments submitted by experts or governments are addressed by the authors. The comments and the author responses, together with the drafts, are published after the report is finalised.
“Our team of around 100 authors have dedicated their time and expertise to develop a meaningful and holistic first draft of the Special Report. We sincerely invite members of the urban community to come forward to provide comments to ensure this report will reflect the latest science and be relevant to the work of urban practitioners around the world,” said Winston Chow, Co-Chair of Working Group II.
“We want to hear the voices of experts from around the world, as we know that city contexts differ worldwide. Expert reviews are critical touchpoints with the global community. They allow authors to consider diverse perspectives and listen to local realities,” said Bart van den Hurk, Co-Chair of Working Group II.
Interested experts can register for participation in the review here. The registration of experts closes on 30 November 2025.
The FOD of the IPCC Special Report on Climate Change and Cities is available for Expert Review from 17 October to 12 December 2025.
For more information about the Expert Review, please contact Woo Qiyun, Senior Communications Manager, IPCC Working Group II Technical Support Unit, media@ipccwg2.org.

The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.
Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, scientists and experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.
The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.
IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.
About the Seventh Assessment Cycle
Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Task Force Bureaus at the IPCC’s Plenary Session in Nairobi.
At its first Plenary Session in the seventh assessment cycle – the 60th Plenary Session in Istanbul, Türkiye, in January 2024 – the Panel agreed to produce in this cycle the three Working Group contributions to the Seventh Assessment Report (AR7), namely the Working Group I report on the Physical Science Basis, the Working Group II report on Impacts, Adaptation and Vulnerability and the Working Group III report on Mitigation of Climate Change. The Synthesis Report of the Seventh Assessment Report will be produced after the completion of the Working Group reports and released by late 2029.
During its 62nd Plenary Session held in Hangzhou, China, in February 2025, the Panel agreed on the outlines of the three Working Group contributions to the Seventh Assessment Report (AR7).
The Panel had already decided during the previous cycle to produce a Special Report on Climate Change and Cities and a Methodology Report on Short-lived Climate Forcers during AR7.. Scientists have also been asked to deliver a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage.
At the IPCC’s 61st Plenary Session held in Sofia, Bulgaria, from 27 July to 2 August 2024, the Panel agreed upon the outlines for the Special Report on Climate Change and Cities scheduled for approval and publication in March 2027 and for the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers scheduled for publication in the second half of 2027.
In addition, a revision of the 1994 IPCC Technical Guidelines on impacts and adaptation as well as adaptation indicators, metrics and guidelines, will be developed in conjunction with the Working Group II report and published as a separate product.
IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provided direct scientific input to the First Global Stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.
The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distils and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.
The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the Ocean and Cryosphere in a Changing Climate (September 2019).

Working Group I of the Intergovernmental Panel on Climate Change is filling the position of
The position is located in the Paris area, at Gif-sur-Yvette (France).
The Intergovernmental Panel on Climate Change (IPCC)
The IPCC was established by the United Nations Environment Programme (UN Environment) and the World Meteorological Organization (WMO) in 1988 to provide policymakers with rigorous, transparent, and objective scientific assessments on climate change, its implications and potential future risks, as well as to put forward adaptation and mitigation options. The IPCC is now undertaking its Seventh Assessment (AR7) cycle. The IPCC Working Group I (WGI) assesses the physical science underpinning past, present, and future climate change. The WGI Technical Support Unit (TSU) provides scientific, technical, operational and communications support that underpin and implement the WGI assessment.
The Technical Support Unit (TSU)
The TSU works at the unique IPCC interface between science and policy in the provision of the climate knowledge and information that is relevant for policy needs and decision making. The team is responsible for facilitating and implementing the assessment process undertaken by the author teams and overseen by the WGI Bureau. We are seeking someone who is highly motivated to join a team that spans different areas of expertise including climate sciences (observations, climate processes, global and regional climate modeling), visual design and communication, digital information development and management, and international project management. The team is hosted by Université Paris-Saclay and located in the facilities of Ecole normale supérieure (ENS) Paris-Saclay in the Paris area.
Role
The TSU is seeking a climate science communications specialist to join a multi-disciplinary team in a dynamic, international working environment. The Communication Officer will work closely with our Information Design and Graphics Officer and in close collaboration with the IPCC Communications Action Team. The successful candidate will coordinate, with the WGI Co-Chairs, Vice-Chairs, Authors and TSU, the communication and outreach of the WGI contribution to the AR7. He/she will take on the challenge of communicating and increasing literacy of the concepts and results of the assessment in an international context to stakeholders, as well as the broader non-specialist audience.

GENEVA, August 18 – The Intergovernmental Panel on Climate Change (IPCC) has appointed 664 experts from 111 countries to participate in the Seventh Assessment Report (AR7) as Coordinating Lead Authors, Lead Authors and Review Editors.
These experts were nominated by governments and IPCC observer organisations and selected by the IPCC Bureau from a global pool of 3,771 nominees.
Of the 664 appointed experts, more than half (51 per cent) come from developing countries and countries with economies in transition. Nearly half of the authors are female scientists, constituting 46 per cent of the group. For comparison, in the Sixth Assessment Report (AR6), the IPCC appointed 721 authors from over 90 countries. Of these, 44 per cent were from developing countries and countries with economies in transition, 53 per cent were new to the IPCC process, and 33 per cent were female. The nominations of all appointed authors have been reviewed under the IPCC’s Conflict of Interest process, and they have accepted their invitations.
“The appointment of the author teams means that work on the Seventh Assessment Report on the state of climate science can now begin. The author teams, drawn from several thousand excellent nominations, ensure outstanding expertise across a range of disciplines. We are proud that the new author teams reflect increased diversity, in terms of both gender balance and greater representation from developing countries and economies in transition”, said IPCC Chair Jim Skea.
The appointed authors will now begin their work on assessing relevant literature and preparing drafts of their respective reports on the basis of the outlines of the Working Group contributions to the AR7, agreed upon by the Panel at its 62nd session in Hangzhou, China, in February 2025. The First Lead Author meeting is scheduled for early December.
The three IPCC Working Group reports are expected to start appearing in mid-2028, while the Synthesis Report that will conclude the entire cycle will be approved by late 2029, completing the seventh assessment cycle.
The list of selected Coordinating Lead Authors, Lead Authors and Review Editors by Working Group contribution to AR7 and chapter can be accessed here.
