COACCH will develop an innovative science-practice policy integration approach to co-deliver an improved downscaled assessment of the risks and costs of climate change in the EU of direct usability for end users from the research, business,investment, and the policy making communities. To achieve this objective, COACCH brings Europe’s leading climate change impacts and economic modelling teams together with stakeholders to co-develop methods and co-produce results and dissemination products using a trans-disciplinary perspective. COACCH researchers will develop technically excellent and innovative research on complex climate change impact chains, climatic and socio-economic tipping points by developing novel modelling tools and approaches that will contribute to advance the physical science, risk assessment and economics. Major innovations include Novel modelling methodologies and approaches will be used to assess the market consequences of climate change impacts, including extreme events over the short- to long-term, on i) macro-economic and sectoral growth, competitiveness; ii) welfare and its distribution. Modelling tools will be complemented with non-modelling approaches to evaluate the non-market consequences on ecosystems,biodiversity, human health, and migration. COACCH will significantly advance the knowledge and the evidence on the socio-economic consequences and non-market impacts of climatic tipping points of major concern for Europe, and explore the new concept of climate-induced socioeconomic tipping points by characterising the likelihood of occurrence of their climate triggering conditions and by assessing the socio-economic and non-market consequences. Besides contributing to major international scientific networks and reports (IPCC, climate-ADAPT platform), COACCH will rely on co-design and public engagement throughout the project to promote easier access to scientific results.

- stock-taking and gap analysis of the existing knowledge on impact analysis and scenarios - development of the SSP/RCP/SPA matrix for climate research that can be used to evaluate climate policy, and have started to use this matrix in impact analysis => development of narrative or pathways - assessment of the direct and indirect impacts and systemic risks associated with climate change and extreme events on (agriculture, crops and livestock, forestry) fishery sectors with MAgPIE - Climate-induced changes to agricultural and natural land, biodiverse ecosystems or intact and frontier forests, GHG emissions, or water environmental flow requirements will be quantified - Case study on policy effectiveness in agricultural business
