Japan and the U.S. may propose that the Group of Eight major industrial powers eliminate or lower import tariffs on energy-saving products, such as fuel cells, solar cells and wind-powered generators to help reduce greenhouse gas emissions, government sources said Wednesday.

The two countries may float the proposal during a two-day, U.S.-sponsored meeting of major greenhouse gas emitters starting Thursday in Washington, the sources said.

Japan wants to make it one of the major achievements of next year's G8 leaders' summit in Hokkaido.
