A government task force on global warming unveiled guidelines Friday calling for promotion of nuclear energy as well as daylight-saving time as part of efforts to reduce Japan's greenhouse gas emissions.

The guidelines, announced at the task force's meeting Friday, are designed to provide specific measures for implementing Japan's 6 percent emissions reduction target adopted at the U.N.-sponsored Kyoto climate change conference last December.

Under the Kyoto Protocol, Japan has agreed to curb emissions by 6 percent from their 1990 levels between 2008 and 2012. The task force, set up in January and consisting of top officials from 16 ministries and agencies, will soon urge the government to follow the guidelines, Environment Agency officials said.
