Abstract
This paper explores the use and perceived usefulness of the 2012 and 2017 United Kingdom Climate Change Risk Assessment (CCRA) reports to identify potential areas of improvement for UK adaptation policy. We conducted interviews with key stakeholders and analysed each CCRA in the context of objective, audience, budget, frame, key findings, dissemination, and how they informed policy. We found that stakeholders used the CCRA in three main ways: (i) to make a business case for their work; (ii) to shape direction of policy or work; and (iii) practical applications. Our findings suggest that the way in which both CCRAs have been operationalized are symptomatic of the UK state reinforcing scientific reductionism in adaptation assessments for policymaking. Recommendations from interviews for future CCRAs included (i) adopting more innovative methodological approaches, (ii) developing more effective mechanisms for operationalisation of the CCRAs, and (iii) improving communication of the CCRAs, their risks and recommendations. This would enable better alignment with user needs and more robust inclusive decision-making processes in the assessment of future UK climate risks and impacts. We discuss how a new framework is needed in which evidence assessments such as the CCRA can be further developed utilising methods of co-production.
