The role of the IPCC in assessing actionable evidence for climate policymaking
jats:titleAbstract</jats:title>jats:pClimate policymakers across the world seek inputs from the research community to determine appropriate policies to reduce greenhouse gas emissions. However, the reports of the Intergovernmental Panel on Climate Change (IPCC), which perform the largest available analytical exercise in this area, offer scarce analytics on climate policy design. Here, we explore how, despite its ‘neutral, policy-relevant but not policy-prescriptive’ principle, the IPCC’s analytical scenario process in Working Group III on Mitigation has adopted an implicitly prescriptive policy position in favour of carbon pricing. Drawing on the example of alternative climate-economic modelling using the E3ME-FTT framework, we explore a pathway for the IPCC process that could cater for diverse ranges of more realistic granular policies. We conclude that, to become truly policy-relevant, the IPCC’s climate mitigation work is in urgent need of reform to provide more effective support for policy design.</jats:p>
