Based on data in EPA's Global Anthropogenic Emissions of Non—CO2 Greenhouse Gases report, in 2005, Japan's estimated anthropogenic methane emissions ranked 45th in the world. Japan's CH4 emissions have decreased in recent years. The decrease in emissions from coal mining greatly contributed to this decrease. Approximately 28 percent of its anthropogenic methane emissions—5.7 MMTCO2E—come from agriculture (manure management), coal mines, municipal solid waste, and natural gas and oil systems.

EPAによる全世界の人為的非CO2 温室ガス報告では、日本の人為的メタン推定排出量は2005年に全世界で45位だった。日本のCH4排出量は近年減少しているが、これには炭鉱からの排出量の低減が大きく貢献している。人為的メタン排出量の約28%に相当する5.7 MMTCO2Eは、農業(有機肥料管理)、炭鉱、埋立てごみ処理地、およびガス・石油コンビナートに起因している。

Methane Sites

The map shows completed and potential methane abatement, recovery, or use projects.

  • Use the check boxes to determine which sites to display on the map.
    • GMI sites are facilities at which methane abatement, recovery, and/or use projects have been identified or completed.
    • Non-GMI sites identify potential or existing projects that are not supported by the GMI.
  • Click a cluster of sites (i.e., numbered circles) to zoom to a region.
  • Click an individual site to view a summary.
  • For more site details click on the highlighted link.

Note: The placement of map icons is approximate, so the zoom-in feature is limited to avoid misrepresentations. Please contact us us if you have more accurate information about the location of a project or site.
