||Hidemichi Fujii, Toxic chemical substances management using TRI data, Kyushu-Illinois Strategic Partnership Colloquia Series, 2021.05, Toxic chemical management is vital to environmental protection and economic development in industrialized countries because it reduces the abatement costs associated with the use of toxic chemicals and minimizes the risk of accidental pollution. However, aspects related to toxic chemical emissions that are generated by the product supply chains that connect consumers to producers have not been widely studied. This talk introduces integrated decomposition analysis framework to clarify the main drivers of changes in the toxicity of production- and consumption-based chemical emissions. The results showed that toxic emissions from the US industrial sector decreased by 83% over the studied period because of pollution abatement efforts adopted by US industries. A variety of pollution abatement efforts were used by different industries, and cleaner production in the mining sector and the use of alternative materials in the manufacture of transportation equipment represented the most important efforts..
||Hidemichi Fujii, How Does Information and Communication Technology Capital Affect Productivity in the Energy Sector?, SNU-KYUSHU JOINT SYMPOSIUM, 2020.09, By focusing on a distributed energy system that has been widely diffused for efficient utilization of renewable energy generation in recent years, this paper investigates the relationship between productivity growth and information and communications technology capital in the energy sector. Information and communications technology is a key factor in operating distributed energy systems in a way that balances energy supply and demand in order to minimize energy loss and to enhance capacity utilization. The objective of this study is to clarify the determining factors that affect productivity growth, focusing on three different information and communications technologies: information technology capital, communication technology capital and software capital. Our estimation sample covers energy sectors in 14 countries from 2000 to 2014. The results show that information technology and software capital contribute to increasing material productivity and capital productivity in the energy sector, respectively. Meanwhile, communication technology capital negatively affects these two productivity indicators..
