The UK Government is required, under the 2008 Climate Change Act, to publish a climate change risk assessment (CCRA) every five years. The assessment sets out the risks and opportunities facing the UK from climate change.
The first risk assessment was published in 2012, and the second in 2017. The third is due in 2022. The CCRA provides the evidence base to inform Government-led national adaptation programmes in England, Scotland, Wales and Northern Ireland.
The Adaptation Committee of the Committee on Climate Change has a legal duty to advise Government on the UK Climate Change Risk Assessment (CCRA). The CCC prepared the second Climate Change Risk Assessment evidence report in 2016, and is now working on an updated evidence report, due to be published in summer 2021, which will inform the UK Government’s third CCRA (known as CCRA3).
Updates will appear on these pages as the project progresses.
Call for external reviewers on the draft of the 2021 UK Climate Change Risk Assessment Evidence Report
This call is aimed at organisations and individuals that are interested in submitting review comments on the draft of the forthcoming UK Climate Change Risk Assessment Evidence Report. The Evidence Report consists of seven substantive chapters. The chapters are:
- Chapter 1 – Introduction: global and UK climate change
- Chapter 2 – Methodology
- Chapter 3 – Natural environment
- Chapter 4 – Infrastructure
- Chapter 5 – Human Health, Communities and Built Environment
- Chapter 6 – Business and industry
- Chapter 7 – International dimensions
The first draft of the report is being reviewed by Government stakeholders and a technical review panel in May 2020. A further review process will take place in September 2020 to allow for final comments on the draft report.
Contributors and research projects
Over 200 people from more than 65 organisations are contributing to the third Climate Change Risk Assessment evidence report. A list of the organisations that are involved is available from the CCC on request.
The University of Exeter is leading a consortium of experts who are preparing the ‘technical chapters’ for the Evidence Report. The technical chapters cover the underlying analysis and assessment of the level of risk or opportunity across the natural environment, infrastructure, people, business and international dimensions. The chapters will also set out the latest understanding of current and future climate change in the UK, and the CCRA method.
Work on this part of the project is taking place between summer 2018 and winter 2020. The CCC will then produce its own synthesis report which summarises the technical chapters and provides the Committee’s advice to Government on adaptation priorities for the next five years.
The CCC is also preparing six research projects to feed into the technical chapters, with funding from the UK Department for Environment, Food and Rural Affairs (Defra); the Devolved Administrations; the Natural Environment Research Council; the Economic and Social Research Council; and the Engineering and Physical Sciences Research Council. The projects include:
- Socioeconomic dimensions: led by Cambridge Econometrics
- Water availability projections: led by HR Wallingford
- Flooding projections: led by Paul Sayers Associates
- Behaviour change: led by AECOM
- Interacting risks: led by WSP
- Thresholds in the natural environment: led by CEH
Final project documents will be published on this website as the projects are completed in 2020.
