To achieve the goals of national sustainable development,the peaking control of CO2emissions is pivotal,as well as other pollutants.In this paper,we build a Chinese inter-regional CGE model and simulate 13 policies and their combinations.By analyzing the energy consumptions,coal consumptions,relating emissions and their impacts on GDP,we found that with the structure adjustment policy,the proportion of coal in primary fossil fuels in 2030 will decrease from 53%to 48%and CO2emissions will decrease by 11.3%e22.8%compared to the baseline scenario.With the energy intensity reduction policy,CO2emissions will decrease by 33.3%in 2030 and 47.8%in 2050 than baseline scenario.Other pollutants will also be controlled as synergetic effects.In this study we also find that although the earlier the peaking time the better for emission amounts control,the economic costs can not be ignored.The GDP will decrease by 2.96%e8.23%under different scenarios.Therefore,integrated policy solutions are needed for realizing the peaks package and more targeted measures are required to achieve the peaks of other pollutants earlier.

To achieve the goals of national sustainable development, the peaking control of CO2 emissions is pivotal, as well as other pollutants. In this paper, we build a Chinese inter-regional CGE model and simulate 13 policies and their combinations. By analyzing the energy consumptions, coal consumptions, relating emissions and their impacts on GDP, we found that with the structure adjustment policy, the proportion of coal in primary fossil fuels in 2030 will decrease from 53% to 48% and CO2 emissions will decrease by 11.3%-22.8% compared to the baseline scenario. With the energy intensity reduction policy, CO2 emissions will decrease by 33.3% in 2030 and 47.8% in 2050 than baseline scenario. Other pollutants will also be controlled as synergetic effects. In this study we also find that although the earlier the peaking time the better for emission amounts control, the economic costs can not be ignored. The GDP will decrease by 2.96%-8.23% under different scenarios. Therefore, integrated policy solutions are needed for realizing the peaks package and more targeted measures are required to achieve the peaks of other pollutants earlier.
