Energy Transition Vulnerability Index for 142 countries and regions

Countries differ widely in their energy infrastructures, economic structures, and socioeconomic contexts, resulting in varying degrees of vulnerability to the energy transition. Advancing a just global transition requires that the most vulnerable are not left behind, and that all countries make measurable progress in reducing vulnerability. To support this effort, we introduce the Energy Transition Vulnerability Index (ETVI), a global metric for assessing national-level vulnerability. The framework draws on the Vulnerability Scoping Diagram and evaluates vulnerability across three dimensions—exposure, sensitivity, and adaptive capacity—in accordance with the Intergovernmental Panel on Climate Change (IPCC) definition. The initial release provides ETVI scores and sub-index values for 142 countries and regions from 2000 to 2023, with annual updates planned. Developed using a consistent methodology, the spatiotemporal dataset enables both cross-country comparison and within-country tracking over time, and serves as a foundation for further research. Insights derived from such research can inform the design of more inclusive energy transition strategies and support international policy coordination.
