This study aims to reveal how much the Tokyo and Saitama emissions trading schemes (ETSs) affect the energy efficiency of manufacturing facilities based on the Economic Census for Business Activity and Census of Manufacture. In this analysis, we estimate the energy efficiency of facilities in Japan using stochastic frontier analysis (SFA). Then, we estimate how much the facilities’ energy efficiency is influenced by the Tokyo and Saitama ETSs. Our results show that the energy efficiency of targeted facilities decreased during the announcement period. Our estimation results show no difference in energy inefficiency between targeted and nontargeted facilities in the implementation period of the ETSs. Additionally, the estimation results imply that carbon leakages through outsourcing did not occur during the implementation period.
