Global monitoring of national health sector response to climate change

Monitoring of national health sector response to climate change is tracked through the WHO Health and Climate Change Global Survey. The survey is sent to national health authorities and is completed in collaboration with other relevant ministries and stakeholders. Information is collected on efforts to protect populations from the escalating health impacts of climate change and to build climate-resilient and sustainable health systems.

Key indicators cover governance and multisectoral collaboration; national health and climate change plans; vulnerability and adaptation assessments; research and evidence; integrated risk monitoring and early warning; climate-resilient and sustainable low-carbon health systems; and financing. Regular updates on these indicators provide a vital snapshot of the overall progress that governments have made and the challenges they face in achieving their health adaptation and mitigation priorities.

The survey is conducted regularly in all WHO Member States. For this, national health authorities complete a comprehensive questionnaire and the national data are then used to monitor implementation of the WHO Global Action Plan on Climate Change and Health and WHO’s Fourteenth General Programme of Work. The 2025 round is the latest of WHO's periodic assessments of national health sector responses to climate change. It builds on the 2018 and 2021 rounds, enabling progress to be tracked over time and highlighting trends and emerging gaps in countries' efforts to protect health from climate change.

A total of 146 WHO Member States and non-Member territories participated in the 2025 survey.
