Abstract: At the general debate of the 75^th Session of the United Nations General Assembly on September 22, 2020, President XI Jin-ping announced that China would scale up its Nationally Determined Contributions by adopting more vigorous policies and measures, strive to peak CO₂ emissions before 2030, and achieve carbon neutrality before 2060. China is taking pragmatic actions to meet these goals. China′s carbon peaking and carbon neutralization strategy is a major demand for the Global Climate Governance, which seeks to protecting Earth and foster a shared global community future. China’s efforts also address the countries’ internal demands for high-quality development, an ecologically-centered nation, and comprehensive management of the ecological environment. The carbon neutralization strategy involves in-depth transformation of social and economic development, with a view to achieve low- or even zero-carbon emissions and increase foreign exchange based on technological change. It is a major opportunity for sustainable development.
