The research paper introduces a global index designed to quantify exposure to transnational climate impacts, arguing that traditional vulnerability indices fail to account for cross-border effects and global interconnections.

This research paper by the South African Institute of International Affairs (SAIIA) introduces two new indices—the Climate Change and Economic Vulnerability Index (CEVI) and the Climate Change and Economic Resilience Index (CERI)—to provide a quantitative basis for the allocation of climate finance. The author argues that current climate finance, particularly OECD adaptation funding, is misaligned with the actual vulnerability and resilience of recipient countries, often favoring middle-income nations over the most vulnerable low-income economies, particularly in Africa.
