This study analyzes the integration of geothermal energy into traditional onsen practices (bathing, snow melting, heating) in a Japanese hot spring village using social practice theory. It shows how traditional practices were reinterpreted …

Keishiro Hara, Yutaka Iwasaki, Yukari Fuchigami

This study conducted a discussion experiment on carbon neutrality with city officials in Suita City, Japan, adopting the perspective of 'imaginary future generations' (IFGs). Results show that IFG adoption leads to changes in policy selecti…

This paper presents Mitsubishi Foods' logistics reform initiatives for building a sustainable supply chain, including modal shift and route optimization. It provides a practical case study for food companies seeking to reduce environmental …

Ryuta Tsurumi, Takahiro Yoshida

This study conducts spatiotemporal analysis of CO2 emissions in Japan's building sector using publicly available data from the mandatory GHG reporting system (FY2021-2022). By integrating floor area data, it evaluates energy use intensity a…

Watanabe D.

This study analyzed the association between diet-related greenhouse gas emissions and mortality among Japanese adults using the Japan Collaborative Cohort Study data. It suggests that low-carbon dietary patterns may also be beneficial for h…
