Abstract Air pollution problems have become very severe in the Beijing-Tianjin-Hebei region of China due to large amount of air pollutant emissions from intensive fossil fuel consumption. Meanwhile, fossil fuel consumption also emits carbon dioxide (CO2) which is a greenhouse gas and causes climate change. Chinese Central Government has set up the Air Pollution Prevention and Control Action Plan, aiming to reduce air pollutant emissions significant through using cleaner energy, industrial upgrading, eliminating high energy consumption industries, and etc. These actions also have potential in reducing CO2 emissions. In this study, we calculate the synergistic effects of the actions in the plan on main air pollutants and carbon dioxide emissions. The objectives include quantitative analysis of the co-benefit from different industries by different measures for different pollutants in the plan.
The Greenhouse gas-Air Pollution Interaction and Synergies model (GAINS) is used in this study. According to each measures in the action plan, new scenarios with modified activities, energy consumptions, the influence of policy, and the equipment levels are generated in the model. The reductions in the air pollutants and CO2 then are simulated for each of the measures. The results indicate that the potential CO2 emission reduction in Beijing and Tianjin from the measures of reducing coal-fired power consumption is 9.2Mt/year and 4.2Mt/year, respectively. In Hebei, the CO2 emission reduction potential of industrial facilities is the largest, up to 122.5Mt/year. Measures for coal combustion power plants in Beijing contribute the most carbon dioxide emission reduction, accounting for 48% of the total CO2 reduction in Beijing. Measures for industries in Tianjin contributes the largest, reaching 42%. Among the main air pollutants the co-benefit carbon dioxide emission reduction is the highest with NOx in Beijing, is the highest with PM2.5 in Tianjin and Hebei.
