As of June 2006, 189 nations have ratified the Convention. Under the Convention, all parties must develop and publish a national inventory of greenhouse gases (GHG) not controlled by the Montreal Protocol. GHG inventories are extremely important as they can provide information on trends in GHG emissions and removals, which allows policy makers to develop measures more effectively and reliably to reduce GHG emissions. GHG inventories are developed according to the guidelines of the Intergovernmental Panel on Climate Change (IPCC). Although these IPCC guidelines contain “default” emission factors and activity data to enable all countries to construct inventories, the parties are encouraged to make efforts to develop their own emission factors and activity data as the “default” values may not represent a particular country’s circumstances. The intensity of each country’s efforts is likely to vary widely as it depends on national conditions. Therefore, information exchange among countries is considered effective to help countries improve the quality of their GHG inventories. “The Workshop on Greenhouse Gas Inventories in Asia (WGIA)” has been organised annually since November 2003 with the support of the Ministry of the Environment, Japan.
