The CCC is currently collecting evidence and preparing its advice for the Fourth Climate Change Risk Assessment (CCRA4), due for publication in 2026. This will look to assess the risks the UK faces today and in the future, and assess adaptation actions that can be taken to reduce these risks.
As part of CCRA4, the CCC will be developing a new output to complement the Technical Report, as produced in previous CCRAs and assesses the range of risks and opportunities facing the UK from climate change and the urgency for adaptation in the next five years. This output – to be known as the ‘Well-adapted UK report’ (WA report) – will focus on the potential for key adaptation actions to reduce the climate risks threatening the achievement of key UK policy and societal outcomes and hence set out a vision for aspects of a well-adapted UK. The WA report aims to provide a policy-relevant evidence base on effective systemic adaptation scenarios, their costs and benefits (and how these are distributed across society) and the investment needs to deliver on them.
