Monthly updated Japanese household carbon footprint

The main objective of this update was to incorporate monthly data up to September 2022, while also adding data at different geographical scales for comparative analysis. Specifically, we have included region-specific data for all years and data for the entire country of Japan. In addition to these improvements, our database includes supplementary information, such as household size for per capita household emissions. We believe that these updates will provide researchers with a comprehensive resource for their data analysis needs. We are supported financially by JSPS Kaken C Number 23K11542.
