Economy Models

China-in-Global Energy Model (C-GEM)

The China-in-Global Energy Model (C-GEM) is a multi-regional and multi-sectoral global computable general equilibrium (CGE) model developed by the China Energy and Climate Project. The model has incorporated China’s economic and social development dynamics and key zero-carbon and negative-carbon emissions technologies. The C-GEM has been applied to evaluate the impact of China’s energy and climate policies on economic growth, industry structure, international trade, energy transformation, and CO₂ emissions.

China Regional Energy Model (C-REM)

The China Regional Energy Model (C-REM) is a multi-regional and multi-sector global dynamic computable general equilibrium (CGE) model that divides China into 30 independent provincial regions. The model captures energy and economic activities of each province in detail and describes major advanced and tranditional energy technologies.

In the latest version of the C-REM, multiple energy-intensive sub-sectors have been disaggregated to allow detailed modeling of the national emissions trading scheme (ETS). The C-REM focuses on evaluating the impact of low-carbon pathways, climate policies, and industrial policies from a regional perspective and analyzing distributional impacts of policies.
