Abstract

Since entering the industrialized era, China’s greenhouse gas emissions and air pollutant emissions have increased rapidly. China is the country with the most greenhouse gas emissions, and it is also facing serious local air pollution problems. China’s industrial sector is the largest contributor to CO2 and air pollutants. The resulting climate change and air pollution issues have caused China to face double pressures. This article uses the CO2 and comprehensive air pollutant emission data of China’s industrial sector as a starting point and uses econometric research methods to explore the synergy between China’s industrial carbon emission reduction and industrial comprehensive air pollutant emission reduction. The synergistic effect between industrial carbon emissions and industrial comprehensive air pollutant emissions has been quantified, and the transmission path of the synergistic effect has been explored. The empirical results show that there are benefits of synergistic governance between climate change and air pollution in China’s industrial sector. Every 1000 tons of carbon reduction in the industrial sector will result in 1 ton of comprehensive air pollutant reduction. The increase in R&D expenditure in the energy and power sector can significantly promote the reduction of air pollutants in the industrial sector. Increasing the intensity of environmental regulations is the main expansion path for synergy. However, in eastern, central, and western China, the synergy is not the same. Therefore, it is necessary to formulate regionally differentiated emission reduction policies. The research conclusions of this article can provide policy references for the coordinated governance of climate change and air pollution in China.

Since entering the industrial era, global greenhouse gas emissions have increased rapidly, and China is the country with the most greenhouse gas emissions in the world [1]
The synergy effect first appeared in the third assessment report issued by the Intergovernmental Panel on Climate Change (IPCC) in 2001, and its meaning is the social and economic benefits of policies and actions to mitigate greenhouse gas emissions

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Since entering the industrial era, global greenhouse gas emissions have increased rapidly, and China is the country with the most greenhouse gas emissions in the world [1]. Excessive emissions of greenhouse gases (mainly CO2 ) lead to climate change problems, and greenhouse gas emissions are one of the main problems in developing and emerging countries [2]. To this end, countries signed the Paris Climate Agreement in 2016.
