Research On The American Air Pollution Control Since 1990s

The United States attaches great importance to the air pollution control, in the 1970 s, the “Command-Control” mode has been used to the control air pollution, and made significant achievements, but to a certain extent the mode hindered the economic development. In the 1980 s, the Reagan administration to continue to develop economy and safeguard the interests of the industry and commerce, they protect environmental negative, lead to adjust the air pollution control policy in stagnation. In the 1990 s, the U.S. government to seek new air pollution governance approach, they have explored a governance mode based on market mechanisms. they promoted the air pollution control policy innovation, and achieved some results. At the same time, the U.S. government to introduce some economic evaluation methods of air pollution control, the cost-benefit analysis is one of them, cost-benefit analysis was used to the air pollution control policy, quantify the of policy implementation in monetary form, and then compare the costs and benefits, provide the basis for the adjustment of the air pollution control policies.In process of air pollution control’s policy making, there are many environmental stakeholders in different subject has different values and interests. They surround air pollution control policy debate, with the aid of science and cost-benefit analysis to pursue the interest of its own as a result, the fact leading to the depoliticize factors had been politicized, about the air pollution control policies. Analysis environment interest game among the subjects, we can perspective the internal mechanism of air pollution control policy of the United States.The article is divided into three parts, the main content is as follows:The first part combed since the 1990 s, the U.S. government’s attitude to environmental protection, air pollution control policies and governance effect. Traces the air pollution control from the "Command-Control" mode to market-based mode transition, embodies the integration of environment and economy.In the second part describes the new standard of PM2.5, coal-fired power plants release of PM2.5 health effects, renovation of the old coal-fired power plant for three specific examples, analyzes the existing in air pollution control policy environment benefit gambling between main body, leading to depoliticize the politicization of the factors, environment subject with the help of science and technology and cost-benefit analysis method such as the pursuit of interest of its results. Environmental problems are no longer just environmental issues, among them mixed with complex political and economic issues, highlights the internal mechanism of air pollution in the United States policy.Finally, the interpretation of the cost-benefit analysis method applied in air pollution control policy in the United States, and through the interpretation of the original data of the Clean Air Act amendment of 1990, cost-benefit analysis to evaluate since the 1990 s the United States the effect of air pollution control policy.
