This report provides a vital snapshot of the overall progress that governments have made in the field of health and climate change to date, as well as insight into what work remains in order to protect their populations from the most devastating health impacts of climate change. The health and climate change country survey is conducted every three years and in addition to tracking global progress, the national data are presented in the health and climate change country profiles. 95 countries participated in the 2021 survey. The survey is sent to the national health authorities, who in collaboration with other relevant ministries and stakeholders, provide updated information on key areas including: leadership and governance, national vulnerability and adaptation assessments, emergency preparedness, disease surveillance, adaptation and resilience measures, climate and health finance, and mitigation in the health sector. Regular updates on key health and climate change indicators provide insight into the implementation of policies and plans, the status of assessments of health vulnerability and capacity to respond to climate change and better understand the barriers to achieving health adaptation and mitigation priorities. The 2021 global survey report provides an update to the 2017/2018 survey, and was published at the COP26 UN climate conference in November 2021.
