Abstract:It brings new challenges to traditional environmental economics in applying market-based instruments to address climate change. The problems arose from existing foreign and domestic carbon emission trading markets (or pilot) have shown the research needs in this area. Therefore, in the Symposium on "Theoretical Advances and Empirical Lessons on Emission Trading Schemes”hosted by Chinese Academy of Sciences, both foreign and domestic scholars have in-depth discussion and ideas exchange on the theory and practice of carbon emission trading scheme. The topics discussed in this symposium covers: carbon emission trading regulations,impact assessment of trading scheme, carbon abatement cost, international experiences, and so on. This paper has reviewed the discussions and perspectives in the symposium, and also discussed the future theoretical and empirical research directions in carbon emission trading.
