Index

The Climate—Conflict—Vulnerability Index (CCVI) maps current global risks by integrating climate and conflict hazards with local vulnerabilities.

Index architecture

The CCVI metrics are organized hierarchically in three pillars — climate, conflict and vulnerability.

Each pillar is based on indicators from publicly available sources, which are further grouped into dimensions.

Following the IPCC definition, risk metrics are computed as a function of hazards, exposure and vulnerability.

Explore the data

The index comprises a harmonized set of data layers and a transparent scoring methodology to make regions globally comparable.

The data is updated quarterly and gridded to 0.5 degrees (ca. 55km by 55km at the equator).
