Measuring the adaptation goal in the global stocktake of the Paris Agreement

The Paris Agreement establishes a global goal on adaptation which will be assessed through the global stocktake, the first attempt by the international climate change regime to measure collective progress on adaptation. This policy analysis identifies four main challenges to designing a meaningful assessment. These are: designing a system that can aggregate results; managing the dual mandate of reviewing collective progress and informing the enhancement of national level actions; methodological challenges in adaptation; and political challenges around measurement. We propose a mixed-methods approach to addressing these challenges, combining short-term needs for reporting with longer-term aims of enhancing national adaptation actions.Key policy insights Broad domains of adaptation activity could be identified within each of the objectives of the adaptation goal and progress could be measured and aggregated through simple scorecards.The goal should have both process and outcome indicators as well as some narrative linking activities to outcomes over time.Reporting could be a compilation of national data using qualitative and quantitative sources, aligning with the global stocktake’s aim of enhancing national actions over time and reducing immediate reporting burdens.There would be a complementary role at least in the short term for an expert assessment of priority areas.
