Comparison of China's Carbon Emission Scenarios in 2050

Several representative studies on China’s carbon emission scenarios in 2050 are compared in scenario settings, methodologies,macro parameters,energy consumption and structure,carbon emissions,and carbon emission intensity. Under the baseline scenario of the present policy framework,the future energy structure will be optimized and carbon emission intensity will decrease continually.China’s carbon emissions up to 2050 show a significant increase reaching between 11.9 Gt and 16.2 Gt COin 2050.By strengthening a low carbon policy,the optimization of energy structure and the decline in carbon emission intensity will become more obvious within the comparative scenarios,which show a significant decrease in carbon emission until 2050 reaching only between 4.3 Gt and 9.5 Gt COby then.
