Japan will review a plan to push for allowing signatory nations to the 1997 Kyoto Protocol to partially achieve mandated carbon dioxide cuts through forest absorption, government sources said Wednesday.

The government set a goal of absorbing more than 50 percent of its mandated carbon dioxide reduction through forests. The plan is being reviewed to prevent other nations from being discouraged from implementing alternative measures to reduce greenhouse gases.

Japan, which is required by the Kyoto Protocol to cut carbon dioxide and other greenhouse gases by 6 percent from its 1990 levels between 2008 and 2012, had considered seeking increased use of forest absorption to achieve the cuts.
