MIMOSA is an Integrated Assessment Model (IAM) part of the IMAGE family, with 26 regions covering the whole world. It is a relatively simple Cost-Benefit IAM that still covers the relevant technological and socio-economic dynamics. The climate impacts are calculated using state-of-the-art COACCH damage functions, and the mitigation costs have been directly calibrated to the IPCC AR6 WGIII database.

MIMOSA is being developed at the Copernicus Institute of Sustainable Development at Utrecht University, and is part of the IMAGE modelling framework.
