After the large increase in mortality due to the heatwaves in June and July 2026 in Europe, the European Regional Hub of the Planetary Health Alliance and more than 80 organisations have signed the European Declaration on Heat and Health, calling on the EU to put health at the centre of its climate policy. The declaration calls for legally binding adaptation obligations, measurable health targets, and a European Heat-Health Action Plan with an emergency fund for hospitals, care homes, nurseries and schools.
