The definitions of afforestation and reforestation refer to the three points of land-use change, when there was forest previously and when it was planted (Kobayashi, 2008b). In addition, upper limits were determined for the application (calculation) of capture volume for the commitment targets of individual countries. Methods of calculating forest capture rates used the IPCC’s “Good Practice Guidance for Land Use, Land-Use Change and Forestry” (IPCC NGGIP, 2003), adopted at the Tenth Session of the Conference of Parties (COP 10) in 2004. Article 8 of this law stipulates the establishment of a framework for achieving Kyoto Protocol targets.
