Japan's National Greenhouse Gas Emissions in Fiscal Year 2019 (Preliminary Figures)

Japan's total greenhouse gas emissions in FY2019 were 1,213 million tonnes of carbon dioxide equivalents (Mt CO₂ eq.).

This reflects a decrease of 2.7% (34 Mt CO₂ eq.) compared to FY2018 emissions (1,247 Mt CO₂ eq.). The two main factors for the decrease in emissions in FY2019 as compared to FY2018 are the reduced energy consumption (reduced production in manufacturing industries etc.) and the decrease in CO₂ emissions from electricity production due to the wider use of low-carbon electricity (wider adoption of renewable energy).

This also shows a decrease of 14.0% (197 Mt CO₂ eq.) compared to FY2013 emissions (1,410 Mt CO₂ eq.). The two main factors for the decrease in emissions in FY2019 as compared to FY2013 are the reduced energy consumption (from improved energy conservation etc.) and the decrease in CO₂ emissions from electricity production due to the wider use of low-carbon electricity (wider adoption of renewable energy, resumption of nuclear power plant operations).

Furthermore, this indicates a decrease of 12.2% (169 Mt CO₂ eq.) compared to FY2005 emissions (1,382 Mt CO₂ eq.). The main factor for the decrease in emissions in FY2019 as compared to FY2005 is the reduced energy consumption (from improved energy conservation etc.).

In contrast, hydrofluorocarbon emissions from refrigerants that substitute ozone-depleting substances are increasing every year.

* These preliminary figures for FY2019 were estimated based on annual figures in various statistics. Some annual figures from FY2018 were temporarily used in place of FY2019 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 2021 may differ from the preliminary figures in this summary. Carbon removals by forests and other carbon sinks will also be estimated and announced at the time of the release of the final figures.
