Study On Synergies Of Air Pollution Control In Shanghai

China’s economy has experienced rapid development during the last decade.Such rapid development induced many environmental problems,such as the frequent haze issues.Although the Chinese government has made great efforts on energy saving and emission reduction,it is still far away from public expectation and environmental quality should be further improved.In particular,it is crucial to reduce the use of fossil energy and reduce the emission of atmospheric pollutants.Under such a circumstance,it is urgent to take a Synergies approach,namely combining the control of air pollution with climate change combat,so that the overall emission reduction effect can be maximized.Such an approach can improve the overall environmental quality and make sure that the urban environment will be more livable.Unlike those institutions in the developed countries such as European countries and the United States,Asian research institutions focus on the coordinated control of climate change policies and environmental pollution,while those institutions in Europe and the United States focus more on the combined effects of policies to mitigate air pollution.Compared with Europe and the United States,China,Japan and South Korea and other Asian regions pay more attention to the synergistic policy effect on actual emission reduction.The main research directions include modelling and scenarios analysis.More recently research institutions pay more attention on the social benefits of emission reduction and its impact on public health.After conducting literature research from both theoretical studies and the real applications of Synergies for controlling greenhouse gas emission reduction and air pollutants reduction both at home and abroad,this thesis focuses on investigating the Synergies of atmospheric pollutant control and greenhouse gas emission reduction.Shanghai is chosen as one case study city due to its large size and diversified industrial structure.Synergies of reducing both greenhouse gas emissions and air pollutants are evaluated so that appropriate mitigation policies can be raised for future improvement.The results show that:(1)Different atmospheric pollutant emission reduction measures can lead to different greenhouse gas emissions,and the Synergies from the thermal power industry is the most significant.Compared with all the single control measures,the combination of structural emission reduction and engineering emission reduction has the most significant effect on the reduction of major atmospheric pollutants and greenhouse gases.(2)Engineering emission reduction measures include end-of-pipe denitrification of flue gas,and super-clean emission modification,which may lead to negative Synergies.The end-of-pipe denitrification of flue gas is more effective than other measures.(3)The emission reduction of mobile sources can also lead to Synergies of atmospheric pollutants and greenhouse gas emission reduction.The upgrading of oil products and the promotion of new energy vehicles,as well as the emission reduction of volatile organic compounds,are useful measures to achieve synergies.(4)Other measures that can lead to synergies include increasing the efficiency of energy consumption,relocation of coke process industries,adjusting energy use structure,etc.The combination of these three measures can result in the most significant synergies.In addition,to phase out those high pollution and high energy consuming industries can also help achieve synergies.
