CO-designing the Assessment of Climate CHange Costs (COACCH)

COACCH (CO-designing the Assessment of Climate CHange costs) is a Horizon 2020 project that aims to advance knowledge regarding climate change impacts and policy that can be used directly by stakeholder communities.



The main objective of the COACCH project is to produce an improved downscaled assessment of the risks and costs of climate change in Europe that can be accessed directly for the different needs of end users from the research, business, investment, and the policy making community. This overall objective breaks down into five specific goals: 

  • To develop complex climate change impact chains by using downscaled climate information and advancing integrated assessment methods and models;
  • To develop a challenge-driven and solutions-orientated research and innovation approach involving stakeholders in the co-design, co-production and co-dissemination of policy driven research;
  • To advance the knowledge and evidence base on climate tipping elements and tipping points and socio-economic tipping points;
  • To advance the economic valuation of climate action (mitigation and adaptation) in the EU at various scales (spatial grids, regions, countries and economic sectors) over short to longer-term timeframes;
  • To enhance innovation capacity and integration of this new knowledge by using co-dissemination of results.

IIASA Research

IIASA will assess the costs of climate change on the agriculture, forestry and fisheries sectors in Europe by further integrating crop, forest and fisheries modelling into the bio-economic land use model GLOBIOM. Medium and long-term economic and environmental impacts on the land use sector will be assessed under various climatic and socio-economic scenarios. Moreover, using an innovative version of the model, GLOBIOM-X, the occurrence and impacts of extreme climatic events and socio-economic tipping points are assessed. Furthermore, the CATSIM model will be used to assess the insurance dimension.
