国际贸易隐含碳排放研究述评

Research review of embodied carbon emissions in international trade

国际贸易隐含碳研究是经济全球化趋势下改善全球气候与环境的主要议题之一。国际贸易隐含碳排放研究对于应对国际减排压力有重要意义。梳理了隐含碳的概念及其渊源,归纳了当前常用的隐含碳核算方法:投入产出法、生命周期法以及新出现的非竞争型模型和新附加贸易统计视角投入产出模型,总结了三种基本的碳排放责任分担机制:生产者责任制、消费者责任制和共同分担责任制,揭示了当前国际认定的生产者负责制的不合理性及未来努力方向。

Research of embodied carbon emissions in international trade is an important issue in improving global climate and environ- ment under the trend of economic globalization, which is of great significance to deal with the pressure of international emission reduc- tion. This paper analyzes the concept of implicit carbon and its origin, and summarizes the commonly methods used to account embodied carbon ： input - output method, life - cycle method and non - competitive model and input - output model from the new added trade sta- tistic angle, and sums up the three basic carbon emission responsibility sharing mechanisms： the producer responsibility system, the consumer responsibility system and the shared responsibility system. It reveals the irrationality of production responsibility system and the direction of future efforts.
