马萨诸塞州诉美国联邦环保局案是美国第一件具有里程碑意义的气候变化公益诉讼案件,该案体现了美国各州和民间力量通过公民诉讼方式促进政府采取温室气体减排行动的艰巨努力。该案从联邦上诉法院一审到联邦最高法院再审,始终存在较大争议,其中关于原告诉讼资格的争议更是人声鼎沸。在联邦最高法院判决中,原告仅以微弱优势胜诉。尽管关于原告胜诉的理由仍有颇多争议,但该案在明确温室气体属于《清洁空气法》的调整范围、拓展气候变化公民诉讼原告的诉讼资格以及确立公民诉讼可以促进政府采取减排行动等方面,都具有非常积极的意义。 Mass. Mass. V. Federal Environmental Protection Agency case is the first case of a landmark public interest climate change litigation in the United States that demonstrates the arduous efforts by states and civilians to promote government efforts to reduce greenhouse gas emissions through civil litigation. The case from the Federal Court of Appeal to the Federal Supreme Court retrial, there is always a big controversy, of which the dispute on the plaintiff litigation is even more crowded. In the federal Supreme Court ruling, the plaintiff won only with a slight advantage. Although there are still many disputes about the plaintiffs’ reasons for winning the case, the case clearly states that the adjustment of greenhouse gas belongs to the Clean Air Act, that the suitability of litigants in expanding climate change litigation and the establishment of citizen litigation can promote the government to take actions to reduce emissions Aspects, have a very positive meaning.
