3E team provided a strong foundation for future policy assessment by developing two new global general equilibrium energy-economic modeling tools: the China-in-Global Energy Model (C-GEM) and the China Regional Energy Model (C-REM). These models represent the latest available data and insights from research in China, and provide a trusted platform for policy analysis in China and abroad.

They assessed a variety of economy-wide energy and climate policy proposals in China, focusing on the design and impact of a future emissions trading system. Studies in this area also assessed the co-benefits of policy proposals for non-targeted environmental and human health impacts. These integrated assessments rely on the use of the C-GEM and C-REM models developed by the group to represent technology detail and how it may respond under changing market or policy conditions.
