Carbon neutrality means that enterprises, groups or individuals calculate the total amount of greenhouse gas emissions directly or indirectly generated in a certain period of time, and offset their own carbon dioxide emissions through afforestation, energy conservation and emission reduction, so as to achieve "zero emission" of carbon dioxide. As a new form of environmental protection, carbon neutrality has been adopted by more and more large-scale activities and conferences.

The significance of carbon neutrality in China is as follows:

China's integration of carbon dioxide emission peak and carbon neutrality into the overall layout of ecological civilization construction is conducive to promoting pollution source control, achieving synergy between carbon emission reduction and pollutant emission reduction, and improving ecological environment quality; It is conducive to alleviating the adverse effects of climate change, especially the extreme weather caused by it, and reducing the losses caused to people's lives, property and economy and society; It is conducive to promoting biodiversity protection and enhancing ecosystem services.
