The model is a modular, highly regionalized, and flexible model built upon the DICE model, with calibrated abaetment costs, a variety of regional climate and impact functions. It includes in a modular fashion features such as within-country inequality, Solar Radiation Management, Carbon Dioxide Removal, and Natural Capital, among others.

The modeling framework considers 58-155 independent countries/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).
