Environmental and climate-related risks are increasingly affecting people’s health and wellbeing across Europe, from air and water pollution to heatwaves, floods, chemical exposure and pressures on health and care systems. Regions and cities are at the forefront of addressing these challenges, translating environmental and climate policies into concrete prevention, resilience and public health measures. This event seeks to explore the links between environmental action, climate resilience and health outcomes, with a focus on the territorial dimension and the role of regions in protecting citizens’ wellbeing. It will also connect to the forthcoming Committee of the Regions opinion on the Environmental Implementation Review, bringing forward regional health perspectives on how stronger environmental implementation can improve public health outcomes, support prevention, reduce inequalities and strengthen resilient communities.
