碳排放交易的背景气候变化已成为国际社会共同关注的全球性问题。2009年12月,中国政府在哥本哈根世界气候大会上作出了到2020年我国单位GDP碳强度降低40%~45%,非化石能源占整个能源结构的15%的承诺。为确保实现这些目标,中国政府正积极推进气候变化的应对措施,在调整经济结构、发展循环经济、推广清洁能源、优化能源结构、提高能源效率、淘汰落后产能等领域采取了一系列政策措施。《京都议定书》提出了三种灵活减排机制:即联合履约(JI,Joint Implement)、清洁发展机制(Clean Development Mechanism,CDM)和碳排放交易(Emission Trading,ET),世界上许多国家和地区先后建立了相应的市场机制以控制温室
Background to the Carbon Emissions Trading Climate change has become a global issue of common concern to the international community. In December 2009, the Chinese government made a commitment at the World Climate Conference in Copenhagen to reduce the carbon intensity of China’s GDP by 40% -45% by 2020 and non-fossil energy by 15% of the entire energy mix. In order to ensure that these goals are met, the Chinese government is actively advancing the response to climate change and has adopted a series of policies and measures in the fields of adjusting the economic structure, developing a recycling economy, promoting clean energy, optimizing the energy structure, improving energy efficiency and eliminating backward production capacity. The Kyoto Protocol puts forward three flexible emission reduction mechanisms: Joint Implementation (JI), Clean Development Mechanism (CDM) and Emission Trading (ET), many countries and regions in the world Has established a corresponding market mechanism to control the greenhouse
