Summary

The purpose of this assessment is to provide a robust, evidence-based estimate of the investment needs – as represented by the cost of implementation of adaptation actions – required to adapt to climate risks in Europe. As climate impacts intensify, understanding the scale and distribution of adaptation investment needs becomes increasingly important for policy planning, budget allocation, and strategic prioritisation.

This analysis supports the European Commission’s overall work on adaptation and resilience, on guiding Member States in developing coherent and cost-effective responses to climate risks and in its efforts to mainstream adaptation into fiscal frameworks.
