Replication dataset for the study “Climate Vulnerability in a South Asia-Centered Polycrisis: Developing the Climate–ESG–Geopolitical Entanglement Index (CEGEI).”

his repository contains the analytical data and replication materials supporting the study “Climate Vulnerability in a South Asia-Centered Polycrisis: Developing the Climate–ESG–Geopolitical Entanglement Index (CEGEI).” The dataset comprises a balanced panel of 216 country-year observations covering Bangladesh, China, India, Nepal, Pakistan, and Sri Lanka from 1990 to 2025. China is included as an adjacent and systemically embedded upstream and geopolitical actor within a South Asia-centered regional system, rather than being geographically classified as a South Asian country. The analytical framework integrates 33 indicators representing climate vulnerability, governance quality, and geopolitical risk. Principal component analysis was used to derive the domain-level components and construct CEGEI, while partial least squares structural equation modelling was applied to examine the relationships among geopolitical risk, governance quality, climate vulnerability, and the interaction term. The repository includes the final analytical panel, variable definitions, source and harmonization documentation, statistical outputs, and replication instructions. These materials are provided to facilitate transparency, verification, replication, and future extensions of CEGEI in other climate-security and transboundary regional settings. Users should consult the variable dictionary and methodological notes before interpreting the component scores, particularly where the direction of ranks, governance indicators, and interaction terms affects substantive interpretation.
