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…
