The MYRIAD_EU project and the Research Unit Sustainability and Climate Risks at the University of Hamburg conducted a workshop to initiate a new macro-economic multimodel intercomparison project on indirect economic impacts of extreme events (macroMIP). The workshop was held as a post conference event of the 30th Annual Conference of the European Association of Environmental and Resource Economists on the 20th June 2025 in Bergen, Norway at the Norwegian School of Economics (NHH). The workshop was convened by Prof. Dr. Jana Sillmann, Dr. Elco Koks, and Dr. Benjamin Blanz.

The macroMIP workshop was attended by different modelling groups such as macroeconomic modelers, IAM modellers, risk assessment experts, and impact modelers, also representing the ISIMIP community. The workshop and discussions focussed on how to compare indirect impacts of extreme events in macro-economic models to improve the understanding of the mechanisms of indirect impacts and to make the assumptions behind different macroeconomic models more transparent. This understanding will allow improvements in the simulation of climate extremes' total economic impacts and provide a comprehensive framework for understanding how local and short-term events can propagate through global supply chains, offering more accurate and actionable insights for sustainable transformation.
