China Energy &. Environmental Policy Analysis Model (CEEPA) aims to perform thorough and elaborate analysis of related energy/environmental policy adjustments or reforms.
      The core of CEEPA is a recursive dynamic computable general equilibrium model. In CEEPA, sixteen sectors were considered (i.e. Agriculture, Iron and Steel industry, Building Materials industry, Chemical industry, Non-ferrous Metals industry, Other Heavy industries, Paper industry, Other Light industries, Construction, Transportation, Service, Coal Mining, Crude Oil Products, Natural Gas Products, Petroleum Refining, and Electricity Production and Supply), as well as two classes of households (urban and rural) and government. The model consists of six basic sub-modules, specifically production, income, expenditure, investment, foreign trade and environment sub-module.

CEEPA has now been successfully applied to assess the impacts of carbon tax on China’s economy, energy use and CO₂ emissions, as well as to examine the effects of energy end-use efficiency improvement. CEEPA can be flexibly modified or extended to perform further analysis such as energy pricing reform, impacts of international energy price fluctuation, potential of CDM, renewable energy policies, etc.
