The University of Exeter led a consortium of experts to prepare the Technical Report in partnership with the Met Office. The Technical Report covers the underlying analysis and assessment of the level of risk or opportunity across the natural environment, infrastructure, people human health, built environment, business and international dimensions. The report also sets out the latest understanding of current and future climate change in the UK, and the CCRA method.
Technical Report of the Third UK Climate Change Risk Assessment (CCRA3)
The Technical Report provides the full analysis for 61 climate change risks and opportunities for the UK. Chapters 0 to 2 cover an introduction, the wider climate change context and method. Chapters 3 to 7 cover the risk assessment split by sector – natural environment; infrastructure; health, communities and built environment; business; and international dimensions.
Chapter 1: Latest Scientific Evidence for Observed and Projected Climate Change
This chapter considers the latest observations of, and future projections for, the changing climate in the UK and across the globe. In particular, this chapter focuses on new projections of climate change arising from developments in climate modelling since the 2nd Climate Change Risk Assessment (CCRA2) in 2017.

Chapter 2: Method
This chapter sets out the methodology for the Third UK CCRA Technical Report (CCRA3). The Technical Report informs the CCRA3 Advice Report, which is written by the Climate Change Committee, and these two documents together are the core components of the CCRA3 Independent Assessment.
Led by: Paul Watkiss, Richard Betts
Chapter 4: Infrastructure
This chapter assesses the climate-related risks and opportunities to infrastructure, primarily focussing on the ‘economic grey infrastructure’ that provides services such as heating, lighting, mobility, fresh water and sanitation to society, aligned with the remit of the National Infrastructure Commission (NIC).
Led by: David Jaroszweski, Ruth Wood, Lee Chapman
Chapter 5: Health, Communities and the Built Environment
This chapter summarises the evidence regarding the key risks and opportunities of climate change for the UK population, with a particular focus on health and wellbeing, and on the built environment.
Led by: Sari Kovats, Rachel Brisley
Chapter 6: Business and Industry
This chapter reviews the current and future climate risks and opportunities for business and industry2 in the UK. It outlines current and planned adaptation directly undertaken by companies and discusses benefits of further action. The main purpose is to inform government action to support private sector adaptation between 2023-2027.
Led by: Swenja Surminski
Chapter 7: International Dimensions
This chapter updates the second CCRA analysis of risks and opportunities for the UK from the observed and projected impacts of global climate change (Challinor et al., 2016). The chapter covers a broad range of initial climate drivers and impacts including food production, violent conflict, human mobility, health and governance.
