Giving full play to the synergistic effect of reduction of pollution and carbon emissions is an important means to systematically promote carbon neutralization. The experience of developed countries shows that incorporating carbon emission targets into the binding targets of economic and social development is conducive to leading and systematic carbon emission reduction，the coordinated efforts of administrative and market means can effectively activate the carbon reduction vitality of market players，Voluntary Emission Reduction and other social mechanisms have established effective channels for promoting the development of a low-carbon society. Based on research on international experiences，this paper systematically analyzes the actual needs and weaknesses of promoting the coordinated reduction of traditional pollutants and carbon emissions both in China and Shanghai，and puts forward counterpart policy suggestions，with the principle of “putting demand control as top priority，focusing on process control，and reinforcing both source management and end-of-pipe treatment”.
