Japan's National Greenhouse Gas Emissions in Fiscal Year 2015(Preliminary Figures)

December 6, 2016

The Ministry of the Environment and the National Institute for Environmental Studies have released Japan's National Greenhouse Gas Emissions (preliminary figures) in fiscal year (FY) 2015.
Total emissions in FY2015 were 1,321 million tonnes of carbon dioxide equivalents (Mt CO2 eq.), a 3.0% decrease compared to those of FY2014; a 6.0% decrease compared to FY2013; and a 5.2% decrease compared to FY2005.The main factor in the drop in emissions as compared to FY2014 is the decreased energy-related CO2 emissions due to the progress of energy conservation and the greater adoption of renewable energy.

Japan's total greenhouse gas emissions in FY2015 were 1,321 million tonnes of carbon dioxide (CO2) equivalent (Mt CO2 eq.).

This is a decrease of 3.0% (41 Mt CO2 eq.) and 6.0% (84 Mt CO2 eq.) when compared to the FY2014 and FY2013 emissions (1,362 Mt CO2 eq. and 1,405 Mt CO2 eq.) respectively, mainly because of the decreased energy-related CO2 emissions due to lowered CO2 emissions from power generation owing to decreased electricity consumption (energy conservation, a cool summer / mild winter, etc.) and the improvement of carbon intensity in power generation (greater adoption of renewable energy, re-operation of nuclear power plants, etc.).

This is also a decrease of 5.2% (72 Mt CO2 eq.) when compared to the FY2005 emissions (1,393 Mt CO2 eq.), mainly due to the decreased energy-related CO2 emissions in industrial and transport sectors, despite the increase in hydrofluorocarbon emissions from refrigerants following their substitution in place of ozone-depleting substances.

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