With the statement of Chinese government on energy saving in 2020 at the United Nations General Assembly, carbon neutral was widely spread as a new concept. As a big country, China has the responsibility and obligation to make its own contribution to global climate change. This paper aims to explore and find effective ways for China to achieve carbon neutrality by 2060. We identify the main factors affecting carbon emissions by STIRPAT model, combined with the scenarios analysis we divide the year 2020 to 2060 into three stages： year 2020-2030 is Carbon Peak stage, year 2030-2050 is Rapid Emission Reduction stage, year 2050-2060 is Complete Carbon Neutralization stage. At each stage, three development models, high, medium and low level, were established. A total of 27 different scenarios in three stages. A system dynamics model was established to simulate the effects of carbon emission factors and changes in carbon sinks in different scenarios. Finally, 8 paths were found which in line with Chinese current goal of achieving carbon neutrality with treating reach Carbon peak in 2030 as an additional filter condition. Comparing per capita GDP levels in different scenarios, we eventually find that keep economic development at a low level in the first stage, a high level in the second stage and a medium level in the finally stage, the point where net carbon emissions are less than zero for the first time will appear between year 2056-2057.By then, the per capita GDP will reach 144,500 yuan (based on year 2000), nearly four times 2000’s. In all, these findings are helpful for policymakers to implement reasonable policies to achieve carbon emission peaking & carbon neutral in China.
