气候变化是当前人类共同面临的全球化问题,世界各国对其给予了广泛关注。近年来，为了积极应对气候变化问题,国际社会进行了多层次的谈判并缔结了相关公约和议定书,从法律的层面对保护气候环境做出了回应。在国家层面,一些国家或地区为更好地应对气候变化已经进行了不同程度的立法实践。2008年，英国颁布了世界上第一部将控制温室气体减排目标写入国内立法的《气候变化法》，为其他国家进行本国气候变化立法起到了指引作用。中国是发展中国家，政府对气候变化问题的态度积极,政策层面已经颁布了一些有关应对气候变化行动的文件 ,并以实际行动进行了相关减排活动。但是，要清醒地认识到我国应对气候变化立法还处于初级阶段,现有立法状况存在很多不足，因此英国气候变化的立法实践值得我国参考和借鉴。本文共分为四个部分。第一部分从国际形势发展的必然趋势和国内发展的必然选择两个方面入手，分析了我国目前构建应对气候变化法律制度的必要性，得出了必须采取法律手段去应对气候变化的结论。第二部分通过对我国应对气候变化立法的现实情况进行梳理，分析出我国在应对气候变化立法方面存在的不足，为后文提出针对性的建言提供了切入点。第三部分系统阐述了英国《气候变化法》的立法背景，并对其主要内容进行了细致总结，并着重分析了英国《气候变化法》立法的成熟经验和合理成分，为中国有选择性地进行借鉴提供了参考。第四部分针对我国目前立法存在的问题，在借鉴英国气候变化立法经验的同时，结合我国国情从六个方面提出了我国应对气候变化立法的建议，具体包括制定一部专门应对气候变化的综合性法律，修订并完善现有法律法规，设立应对气候变化的专门机构，加强气候变化立法的可操作性，建立国内碳排放交易机制的法律法规以及通过立法突出公民应对气候变化的参与机制。

Climate change has already become the focus that international community has paid close attention to as a global environmental problem. In recent years, in order to actively response to the issue of climate change, the international community had made multi-level negotiations and signed many relevant conventions and protocols, and have responded to the climate environment from the legal perspective. Many countries are also actively developing the relevant policies and laws to address climate change. In 2008, The UK issued Climate Change Act which is the world's first one will control greenhouse gas emission reduction targets into domestic legislation, which played an exemplary role for other countries to develop national climate change law. China as a developing country，the government takes positive and responsible attitude to the issue of climate change and take practical actions of relative emission reduction activities. However, we must clearly recognize that our climate change legislation are still at an early stage and there are many shortcomings in the exiting stage legislation, therefore The UK's legislative practice in coping with Climate Change is worth being as reference.This article is divided into four parts. In the first part of the article, from two aspects of the inevitable trend of the international situation and the inevitable choice of domestic development, the paper analyzes the necessity of establishing legal mechanism in coping with climate change in china, and concludes that we must take legal means to address climate change. In the second part of the article, the paper sorts out the legislative status of China's response to climate change，and analyzes shortcomings of China's response to climate change legislation. In the third part of the article, the author described the legislative background of the UK Climate Change Act, and summarizes the main content. The paper analyzes the mature experience and rational components of the legislation of climate change, which provides a theoretical basis for China. In the fourth part, taking into account the problem of legislation, learning from the experience of The UK climate change legislation and according to our country, the author makes six recommendations in legislation for China addressing climate change, including the creation of a special climate change legislation, to further improve the response to climate change in the legal system, to establish an specialized agencies to deal with climate change, to strengthen the operability of climate change legislation, to establish domestic carbon emissions trading system and to emphasize the important role of citizen participation.
