| Over the years, Canada and the United States on the issue of acid rain pollution has been in dispute. Because the United States highly industrialized northern border region continued to spread rumors about a large number of large coal-fired power plants polluting substances, and these polluting substances in climate and other natural conditions under the influence of transboundary drift into Canada, causing long-range transboundary acid rain pollution. Since the late 1970s, Canada from the United States since the problem of acid rain, the two sides launched more than 30 years of diplomatic experience: In the 1980s, in Canada unilateral active diplomatic efforts, the two sides Canada and the United States on the problem of acid rain launched several rounds of negotiations, 1985 Maerluoni During the visit has taken meaningful step, launched a "Davis - Lewis investigation, " Reagan in 1986, "Davis - Lewis investigation report" was signed, and in the subsequent Reagan and Malraux Nepal talks on the peak of the Reagan senseless Canada and the United States to ensure that the negotiations in trouble. Bush and until 1989 on the problem of acid rain Maerluoni to carry out consultations, the United States finally agreed to negotiations with Canada to reach a common management agreement. In the early 1990s, Canada and the United States, "Air Quality Agreement, " the two sides initialled the text was finally down. Over the years, agreements and the fulfilment of the United States. Canada and the United States parties to take effective measures so that the two countries especially Canada's air and water quality control and improvement. Facts have proved that the Government of Canada has consistently worked to develop a bilateral pollution control system to ensure that the United States in dealing with the issue of obligations related to the principle is correct.Canada and the United States the two countries on the settlement of disputes and the problem of acid rain compromise , negotiation and cooperation , showing the interdependence between the two countries, mutually contradictory to the special relationship between Canada and the United States diplomacy is a microcosm of the world environment in a typical diplomatic significance. The problem of acid rain has become a long-term diplomatic relations between Canada and the United States the crux of the matter is that it has already gone beyond the general sense of ethical concepts and purely technical operation, but the state's sovereignty and national interests. This paper on Canada and the United States launched a diplomatic acid rain-depth political analysis: on the one hand in the governance of Canada acid rain pollution taken by the various positive measures with the United States having its way in the environment diplomatic unilateralism formed a sharp contrast, the United States Government from the initial awareness only to the problem of acid rain, acid rain has been regarded as the national or local matters, not the problem of acid rain as international affairs, and Canada successive governments cooperate with the United States requested the acid rain control position is consistent, since 1977 , Canada each session of the environment ministers responsibility, as the problem of acid rain, are to control acid rain pollution problems. On the other hand, the problem of acid rain on the United States in the implementation of double standards. The United States and Canada on the problem of acid rain reached a preliminary agreement with the 15 time, and another is to resolve cross-border pollution problems, the United States and Mexico "Air Quality Agreement, " the brewing from the outset to reach an agreement only used less than half the time, the reasons for the United States is a victim of cross-border pollution. Clearly, this state of affairs behind a political move because, first, the final analysis is always to their national interests and international policies services; Second, the United States make full use of its environment, including acid rain, global foreign policy to promote the implementation of the policy; 3 acid rain on the environment can be used to coordinate foreign policy and the relationship between the United States and each other. Of course, the implementation of such a foreign policy is subject to the constraints the country for several reasons, mainly reflected in the change of government, Congressional legislation, as well as funding and personnel constraints, and so on. Canada and the United States are also on the problem of acid rain on the environment diplomatic detailed analysis of the economics: the acid rain control, in the final analysis or related to the Canada-US issues to the national interests of the two countries. Environmental economics of pollution as an external analysis, and the transboundary acid rain pollution is the most typical international external issues. Game theory analysis of transboundary pollution issue of international cooperation to provide a new way of thinking, Mahler 1989 in the European study the problem of acid deposition obtained transboundary pollution problems Game Theory applied research in the first empirical results. However, as this function is considerable uncertainty, namely the assumption that all countries are in Mahler Nash equilibrium, and the marginal cost reduction coefficient divided by the transfer can be regarded as marginal cost of damage, this is undoubtedly based on the assumption that acid rain pollution at the international level is inherent , another Mahler payments calculated under the conditions of unilateral complete cooperation results, but if it is impossible for unilateralism, it will not have the complete cooperation explained that the result, Mahler Pareto advantage of a simulation results and in a dynamic framework, and ultimately concluded that applied to Canada and the United States on the management of transboundary acid rain pollution, Canada and the United States that the two countries strengthen bilateral cooperation to tackle acid rain is an important channel for cross-border pollution.Canada and the United States on the problem of acid rain environmental diplomacy and the two sides eventually resolved for the common management of transboundary pollution problems provided a good reference. Finally, the analysis of the transboundary acid rain pollution outside of the international and cross-border pollution control and the difficulties facing the challenges on the basis of the proposed transboundary acid rain pollution control diplomatic countermeasures , and give full play to the role of non-governmental organizations; the establishment of an international environmental court; appropriate restrictions on the sovereignty agreement views. |
