The Global Climate Change Alliance plus (GCCA+) index is an open source index which facilitates the ex-ante evaluation of the structural features of the vulnerability to climate change of the target countries of the EU GCCA+ programme. ( )

The GCCA+ index aims to support climate-resilient development, by helping to reconcile climate change policy objectives with development goals. Such efforts should create win-win opportunities, by ensuring that current and future climate risks are systematically integrated into development strategies designed to foster economic growth, poverty reduction and other development objectives.


The GCCA+ index is a “fit for purpose” index that addresses the GCCA+’s policy objective of boosting the efficiency of response to the needs of vulnerable countries and groups. It covers the social, economic and environmental aspects of achieving climate-resilient development by aggregating 34 country-level ‘fit-for-purpose indicators’, which have been identified on the basis of both their relevance within the scope of the GCCA+ flagship initiative, and compliance with the following criteria:

  • reliability,
  • open source,
  • consistency,
  • scientific robustness,
  • global coverage,
  • based on data which are in the public domain.

This web platform serves as an interface between science and policy. It provides transparent, reliable, accurate, and open source information on the indicators, data and methodology applied to build the index. It allows users to examine the factors behind the index and the indicators.
