Smoke billow from factories at an industrial zone in Tokyo, in this January 17, 2009 file picture. Japan on November 15, 2013 drastically weakened its greenhouse-gas reduction target, bowing to the impact of a shuttered nuclear power industry but drawing international criticism at U.N. climate change talks. The change in the carbon dioxide-emissions goal is a dramatic turnaround for a nation that had championed the earlier Kyoto treaty on climate change. But it was made inevitable when the nation's 50 nuclear plants were closed in the wake of the March 2011 earthquake and tsunami, which wrecked the Fukushima facility northeast of Tokyo.
