Japan’s National Greenhouse Gas Emissions in Fiscal Year 2010(Preliminary Figures)
The Ministry of the Environment, summarized Japan’s National Greenhouse Gas Emissions (preliminary figures) in fiscal year (FY) 2010.
Japan’s total greenhouse gas emissions in FY 2010 (the preliminary figures1) were 1,256 million tonnes of carbon dioxide equivalents. They decreased by 0.4 % compared to those of the base year2 under the Kyoto Protocol (FY 1990 for CO2, CH4, N2O and calendar year (CY) 1995 for HFCs, PFCs, SF6).
Compared to those of FY2009, emissions in FY2010 increased by 3.9% due to an increase in CO2 emissions from all sectors, especially Industries. The primary reason for the emissions increase in FY 2010 was the recovery from the economic recession induced by the Global Financial Crisis of 2008. The emissions from manufacturing increased due to a recovery in the level of activities. In addition, electric power demand increased due to the relatively high number of days on which extremes of hot or cold were experienced.
1Concerning the estimation of the preliminary figures: This estimation of the greenhouse gas emissions is based on annual data compiled from statistics from a variety of sources; however, some of this data is not yet available. For such data - for which FY 2010 values are not available - the FY 2009 values were used to estimate the preliminary figures. Therefore, there may be some differences in the preliminary figures reported here compared to the final figures to be reported in April 2012.
2Concerning the relationships with the Kyoto Protocol target: The value “0.4% decrease” does not take into account either the promotion of forest carbon sink measures or the Kyoto mechanisms - therefore, this value, and Japan’s Kyoto Protocol target “-6%” can not be directly compared.
