The 3rd COACCH co-design workshop was held online over two days on 3 and 4 December 2020. More than 40 participants joined, representing all four COACCH working groups: policy makers, investors, business and industry, research and civil society. On the first day, researchers presented the results of impact assessments for a number of physical and socio-economic tipping points and discussed these with stakeholders. On the second day the participants discussed the results of the COACCH macroeconomic assessment of climate impacts. The team also previewed a web-tool to assist with decision making. A final session was focused on risk perception and policy needs. The evaluation process on co-design was continued with an evaluation survey at the end of the workshop.
