Abstract
The carbon sink issues under the Kyoto Protocol had been negotiated intensively since COP3 until the agreement at COPT. Although, one of the largest carbon sink activities (3.9%) are allowed for Japan to achieve the reduction target (6%), there are still many issues need to be addressed regarding the implementation, such as additional forest management, development of the carbon accounting system etc. Especially, regarding the monitoring of the carbon sink activities, the Kyoto Protocol mandates each countries to report in a transparent and verifiable manner. In this regard, it is expected that the remote sensing techniques play a major role in establishing the carbon sink assessment system to meet the need of the Kyoto Protocol and beyond. This report review the international agreement associated with the carbon sink article, the cutting edge methods for the carbon sink assessment, and the related international research activities.
