Facilitation of working groups to enable a sectoral approach to the fourth UK Climate Change Risk Assessment

The UK Climate Change Risk Assessment

Under the Climate Change Act 2008 (section 57), an assessment of the risks facing the UK from the current and predicted impact of climate change is required every 5 years. The CCC is responsible for providing independent advice to the UK Government to inform that assessment.

In summer 2021, the Committee provided its advice to the UK Government on the risks and opportunities facing the UK from current and future climate change as part of the third Climate Change Risk Assessment (CCRA3). This was summarised in its Independent Assessment of UK Climate Risk.

The Committee’s advice on the fourth UK Climate Change Risk Assessment (CCRA4) is due for completion by June 2026. CCRA4 will aim to assess climate change risks to the UK using a more holistic, sectoral approach than previous CCRAs, so that the interactions between risks and the co-benefits of different adaptation actions may be better understood.
In particular, the outputs of CCRA4 will include a ‘Well-adapted UK’ report that will aim to synthesise in-depth, systemic assessments of the risks to key areas of the economy and society, as well as the interdependencies and cross-cutting interventions between these, bringing together a strategic case for adaptation action. We intend to base these systemic assessments on tailored, in-depth and quantitative modelling commissioned by the CCC, as well as the wider published evidence base.

To ensure that the outputs of these assessments – and hence the outputs of CCRA4 – are as useful as possible for the priority audience of Government stakeholders and decision makers, the specifications for the modelling will be co-developed with these stakeholders. By tailoring the research to end-user and decision-maker need, CCRA4 aims to be well placed to drive adaptation action. The co-development of the outputs and evidence base will continue throughout the CCRA4 cycle, but the first step is to build an initial understanding of stakeholder priorities and where the proposed in-depth, systemic assessments can add most value and how. In particular, this first phase of engagement with stakeholders will help to inform the topics and sectors that will be the focus of tailored modelling projects going forwards, by highlighting where such research would be feasible and where it would add most value for driving adaptation action.
