In a comprehensive analysis of climate adaptation efforts, this EU report reveals significant progress and challenges in addressing climate hazards and vulnerabilities worldwide, achieved by the Global Covenant of Mayors for Climate and Energy signatory municipalities. Extreme heat, droughts, and floods have been identified as prevalent climate hazards. Notably, only 67 % of high-risk hazards have corresponding adaptation actions in place. A substantial gap persists between identified risks and the implementation of actions, particularly in vulnerable sectors and populations. Policymakers are called to bridge this gap to improve resilience against climate impacts.
