The rapid rise of carbon dioxide and other greenhouse gases in the atmosphere and the global climate change caused by it are the major problems facing human society. China is the world's largest emitter of greenhouse gases and plays a key role in global climate change governance. At the United Nations General Assembly in 2020, the Chinese government proposed for the first time to strive to achieve carbon peak by 2030 and carbon neutral by 2060. Focusing on the path and mode selection of China's carbon neutralization goal, this paper puts forward a comprehensive governance mode of China's response to climate change, that is, a multi-stage mixed dominant carbon neutralization mode. The first mock exam is to adjust and balance the relationship between China's CO2 emissions from human activities and the amount of anthropogenic CO2 absorbed by the state through the reduction of emissions and the increase of foreign exchange channels under the constraints of the state and within the environment and within the environment. Its interior is composed of macro, meso and micro structures, each of which is different. The proposal of multi-stage mixed dominant carbon neutralization mode expands and improves the theory of integrated governance of climate change, and provides mechanism reference for climate change governance.
