Changes in carbon dioxide emissions by sector and industry during travel restrictions in Japan due to COVID-19

Abstract

This study assessed changes in CO2 emissions during the COVID-19 countermeasures period as a basic study to understand the possibility of reducing CO2 emissions through society-wide mobility restrictions. The results of this study showed that CO2 emissions in the transportation sector decreased, while emissions in the residential sector increased. In the commercial sector, emissions decreased in industries that involved facility closures or reduced business hours, such as the service industry. On the other hand, there was little change in industries that mainly involve office work.
