This document discusses energy usage and CO2 emissions at multiple technical colleges in Japan from 2016 to 2020. It provides data on inputs like electricity, gas and outputs like CO2 emissions. CO2 emissions decreased from 2016 to 2020 due to improvements in energy efficiency and a switch to renewable energy. Total energy usage peaked in 2018 but has trended downward since, while total CO2 emissions have reduced by around 4% per year.
