My major research area is the effectiveness of economic instruments on climate change and air pollution. Carbon pricing, such as carbon tax or emission trading schemes (ETS), has gained attention as a mitigation policy. In Japan, the local governments of Tokyo and Saitama have adopted ETS, although there is no ETS at the national level. I received funding from the Japanese Ministry of the Environment ERCA (2-1707) to conduct an ex post analysis of the Tokyo and Saitama ETSs.

In addition, I investigate the policy option of carbon pricing to address the competitiveness issue and carbon leakage under carbon pricing. I also examine the possibility of a double dividend for the Japanese economy using a carbon tax.
