Extreme temperatures, including heat and cold waves, are climatological hazards. Both in the EU as well as in EU-Neighbourhood countries, research has shown that heatwaves cause a rise in morbidity and mortality. Since heatwaves are not restricted to country borders, a cross-border approach is required to ensure collective preparedness and response to mitigate the impacts on communities and limit the financial and health costs. The overall objective of SCORCH is to reduce the impact of heatwaves on vulnerable, urban populations through improved risk communication strategies based on existing EU plans and guidelines. In addition, we will measure risk perception and behaviour in communities in EU-neighbourhood countries through surveys and foster a cross-country culture of prevention and cooperation. To make maximum use of existing knowledge and strategies on heatwaves, the project starts out by collecting existing heatwave plans of EU countries. Based on these plans we aim to identify the necessary building blocks that make up a heatwave plan. Through this overview and a literature review on studies that evaluated existing heatwave plans (deliverable 2.2.), we aim to help find a standard for developing a heatwave plan and apply this to the development of the risk communication strategies in WP4. This report outlines the methodology used for collecting and subsequently analysing existing heatwave plans; and describes the results of this effort.
