Abstract
Air pollutants and CO2 emissions have a common important source, namely energy consumption. Considering fairness and efficiency, the provincial coordinated allocation of energy consumption, air pollutant emission, and carbon emission (EAC) quotas is of great significance to promote provincial development and achieve national energy conservation and emission reduction targets. A weighted environment zero-sum-gains data envelopment analysis (ZSG-DEA) model is constructed to optimize the efficiency of the initial provincial quotas under the fairness principle, so as to realize the fairness and efficiency of allocation. The empirical analysis in 2020 shows that the optimal allocation scheme proposed in this study is better than the national planning scheme in terms of fairness and efficiency, and the optimal scheme based on the initial allocation of priority order of “capacity to pay egalitarianism > historical egalitarianism > population egalitarianism” is the fairest. The optimal allocation scheme in 2025 can achieve absolute fairness. In this scheme, the pressures of energy conservation and emission reduction undertaken by different provinces vary greatly. The implementation of regional coordinated development strategies can narrow this gap and improve the enforceability of this scheme. Combined with the analysis of energy conservation and emission reduction in seven categories and three major national strategic regions, we put forward corresponding measures to provide decision support for China’s energy conservation and emission reduction.
Highlights
Economic development needs to consume a large amount of energy, and the consumption of energy is accompanied by the emissions of CO2 and air pollutants such as NOX, SO2, and inhalable particles
Since energy is an important input resource for regional economic development, maintaining the continuity of energy consumption is very important for stable economic development
The proposed weighted environmental zero-sum-gains data envelopment analysis (ZSG-DEA) model has the following advantages: first, it considers the strong disposability of energy, population, fixed assets, and other input factors and expected output GDP, as well as the weak disposability and nulljointness of unexpected outputs such as air pollutants and CO2 emissions, which is more in line with the reality of economic production
Summary
Economic development needs to consume a large amount of energy, and the consumption of energy is accompanied by the emissions of CO2 and air pollutants such as NOX , SO2 , and inhalable particles. CO2 is an important component of air, which does not directly cause air pollution, but its large increase affects climate change, and damages the ecological environment. As the largest developing country, China’s economy has developed rapidly in recent years, but it has brought great energy consumption, CO2 emissions, and atmospheric environmental pollution. According to BP Statistical Review of World Energy, in 2020, China’s energy consumption and CO2 emissions accounted for. The Chinese government attaches great importance to the control of energy consumption, air pollutants, and CO2 emissions and has put forward a series of measures such as total quantity control, provincial quota allocation, and emissions trading. In 2016, Chinese State Council issued the Work Plan for Controlling Greenhouse Gas
