A multi-regional Integrated Assessment Model, described in the paper ‘Persistent inequality in economically optimal climate policies’, Gazzotti et. al, 2021, Nature Communications https://www.nature.com/articles/s41467-021-23613-y

The modeling framework considers 57 independent regions. The dynamics of economic growth, greenhouse gases (GHG) emissions, emissions mitigation costs, and economic impacts due to climate change follow the well-known integrated assessment model DICE. The regional representation is consistent with the finest granularity at which data, especially marginal abatement costs curves (MACC), is available. Socioeconomic drivers, including population and economics growth at the country level, come from the five Shared Socioeconomic Pathways (SSP). Therefore, the model spans over five coherent alternative future socioeconomic development pathways.
