2025 WHO health and climate change global survey report

Overview

The 2025 WHO Health and Climate Change Global Survey report provides a global assessment of country-level progress in addressing the health impacts of climate change and developing climate-resilient and low-carbon health systems. Drawing on responses from 146 countries, this edition expands the scope of previous surveys and establishes a baseline for monitoring the WHO Global Action Plan on Climate Change and Health and the climate-related outcomes of WHO’s Fourteenth General Programme of Work.

The findings indicate that national governance structures, vulnerability and adaptation assessments, and climate and health planning have expanded, but implementation remains limited. More than 90% of countries have designated climate and health focal points, while over half have national strategies or health adaptation plans. However, insufficient financing, limited workforce capacity and inadequate monitoring continue to constrain progress. The transition towards low-carbon and sustainable health systems remains at an early stage, with persistent inequalities affecting lower-income countries. The report highlights the need to strengthen implementation, expand access to financing and build health system resilience.
