The 9th International Conference on Energy, Resources, Environment and Sustainable Development (ERESD 2022)

In order to adapt to the low-carbon and green environmental development trend,China has implemented emissions trading scheme (ETS) for seven regions since 2010, ETS is an effective market-based instrument to achieve lower CO2 emissions. A number of studies have confirmed the effectiveness of the approach.However, there is incomplete research on the effect and influencing channels of emission trading on carbon intensity reduction. To explore these problems, The studies conducted an empirical analysis,using the log-averaged Divisia Index (LMDI) to decompose industrial carbon dioxide (CO2) emissions for the seven pilot regions from 2006 to 2019 into economic size, economic structure, energy efficiency, and energy mix effects.Then, a difference-in-difference (DID) model evaluates the implementation effects of this ETS,Finally, using a mediating effects model to study the specific pathways affecting carbon emission reductions.The main conclusions are as follows: (1) China's emission trading pilots have driven a significant decline in the carbon intensity.(2)the change in industrial CO2 emissions is mainly due to the energy scale and energy efficiency effects.
