In order to deal with the increasingly severe climate change and energy crisis,explore efficient energy conservation and GHG emission reduction policies and complete the quantitative evaluation of relevant policies,the LEAP model of Shaanxi Province is established according to the Shaanxi statistical yearbook and combined with the actual situation of Shaanxi Province.This LEAP model includes four parts:energy demand module,energy transformation module, resources supply module and GHG emission module.And based on the forecast of the development in population and economy of Shaanxi Province this paper has made a prediction on the energy consumption and GHG emission of Shaanxi Province in different policy scenarios,and conducted an analysis of the energy conservation and GHG emission reduction potential of the relevant policies.The results show that with the implementation of various policies,Shaanxi Provinces energy consumption and GHG emission will be decreased with the implementation of various energy conservation and emission reduction policies.The primary energy consumption of Shaanxi Province in 2030is expected to be decreased by 20.35% compared with the baseline scenario;the GHG emission will be reduced by 27.29% The renewable energy generation technology has made a great progress in energy conservation and GHG emission reduction,and most contribution to energy conservation and emission reduction was made in industry, transportation and power generation.So,generally speaking,Shaanxi Province has enormous potential in energy conservation and GHG emission reduction.
