A Gansu-LEAP model was constructed based on the LEAP model and scenario analysis,and set four development scenarios:benchmark scenario,development scenario,target peak reaching scenario and early peak reaching scenario,to predict the energy consumption and carbon emission in Gansu Prov-ince under different scenarios from 2020 to 2060.The results showed that the energy demand of Gansu Province would peak in 2037,and the carbon emission peak in 2032.Optimizing industrial structure,re-ducing energy intensity,improving energy conversion efficiency and using clean energy are the main methods to reduce energy consumption and carbon emissions.
