Japan's National Greenhouse Gas Emissions in Fiscal Year 2020 (Preliminary Figures)

The Ministry of the Environment and the National Institute for Environmental Studies have released Japan's National Greenhouse Gas Emissions (preliminary figures) for fiscal year (FY) 2020.

Total greenhouse gas emissions in FY2020 were 1,149 million tonnes of carbon dioxide equivalent (Mt CO2 eq.), down 5.1% compared to FY2019 (reflecting an 18.4% decrease compared to FY2013 and a 16.8% decrease compared to FY2005).

Note: Japan's fiscal year runs from April 1 to March 31.

The greenhouse gas emissions by gas and by sector are available in the attached file. A detailed analysis of the reasons for the increases/decreases in emissions will be done for the final figures to be released in April 2022.

* These preliminary figures for FY2020 were estimated based on annual figures in various statistics. Some annual figures from FY2019 were temporarily used in place of FY2020 figures that have yet to be released. Moreover, some estimation methodologies are currently being reconsidered in order to make more accurate estimations of emissions for the final figures. As such, the final figures to be released in April 2022 may differ from the preliminary figures in this summary. Removals by measures for forests and other carbon sinks will also be estimated and announced at the time of the release of the final figures.
