Japan's Environment Ministry has a new rule aimed at cutting greenhouse gas emissions: lights out at 8 p.m.
The new policy will be implemented at ministry headquarters beginning April 3. Those staying late will have to work together in a single conference room, said ministry official Masanori Shishido.
Under the gun to meet obligations under the Kyoto Protocol on global warming, Japanese ministries are trying to cut back on CO2 emissions from their offices by 7 percent from the 2001 level by March 2007.
