Professor Toshi H. Arimura's research lab specializes in energy economics and environmental policy, focusing on the cost-effectiveness of energy efficiency and demand-side management programs, carbon pricing mechanisms, and emissions trading schemes. The lab conducts rigorous econometric analyses using micro-level data to evaluate the long-term impacts of policy interventions on energy demand, greenhouse gas emissions, and industrial behavior. A key research direction involves assessing the effectiveness of climate policies in Asia, particularly in Japan, with comparative insights from North America and Europe.

We specify a model that relates electricity demand to previous EE DSM spending, energy prices, income, weather, and other demand factors. In contrast to previous studies, we allow EE DSM spending to have a potential longterm demand effect and explicitly address possible endogeneity in spending. We find that current period EE DSM expenditu
Abstract Tokyo ETS is the first emissions trading scheme to control GHG emissions from office buildings. Although the Tokyo government claimed that Tokyo ETS had been successful, some argued that the emission reduction under Tokyo ETS was actually the result of electricity price increases triggered by the Great East Japan Earthquake in 2011. Using a facility-level data set for Japanese office buildings, we conducted an econometric analysis to examine the impact of Tokyo ETS. We found that half o

This open access book evaluates, from an economic perspective, various measures introduced in Japan to prevent climate change. Although various countries have implemented such policies in response to the pressing issue of climate change, the effectiveness of those programs has not been sufficiently compared. In particular, policy evaluations in the Asian region are far behind those in North America and Europe due to data limitations and political reasons. The first part of the book summarizes me
Economic growth in Asia has increased in the past three decades and has heightened energy demand, resulting in rising greenhouse gas emissions and severe air pollution. To tackle these issues, fuel switching and the deployment of renewables are essential. In the present paper, we discuss the environmental regulations, mainly carbon pricing, implemented in Asia and discuss their achievements. Empirical studies using microdata have shown that carbon pricing in Asia can reduce carbon emissions by p
ABSTRACT The IPCC (Intergovernmental Panel on Climate Change) special report on the impacts of global warming of 1.5°C urged the world to move toward carbon neutrality (CN). Following the announcement by European countries of their CN target by 2050, Japan, South Korea, and the USA announced their CN targets by 2050. However, the Russian invasion of Ukraine has divided the world and drastically changed energy markets, including natural gas. Moreover, the EU is now implementing controversial poli
