IMPACT2C enhanced the knowledge, quantified climate change impacts, and adopted a clear and logical structure, with climate and impacts modelling, vulnerabilities, risks and economic costs, as well as potential responses, within a pan-European sector based analysis. IMPACT2C utilised a range of models within a multi-disciplinary international expert team and assesses effects on water, energy, infrastructure, coasts, tourism, forestry, agriculture, ecosystems services, and health and air quality-climate interactions. IMPACT2C key innovations was (a) individual and cross-sector assessments aligned to the 2°C and1.5°C scenarios for both impacts and adaptation, (b) a core theme of uncertainty, and will develop a methodological framework integrating the uncertainties within and across the different sectors, (c) an assessment of impacts in some of the world’s most vulnerable regions and (d) integration and synthesis communicable through the IMPACT2C web-atlas.
