Japan pledges 20 percent cut in emissions

Japan will promise to cut its greenhouse gas emissions by 20 percent from 2013 levels ahead of a global summit on climate change this year, a report said on Thursday, despite uncertainty over post - Fukushima energy policy.

The government will likely announce the new target at the Group of Seven summit in June in Germany, the leading business daily Nikkei reported, citing unnamed government sources.

In a separate report, Kyodo News said Tokyo will set a target of cutting gas emissions "by at least 20 percent by 2030, from 2005 levels".
