Japan’s Ministry of the Environment estimated July 20 that last spring’s Fukushima Daiichi Nuclear Power Station accident led to increased fossil fuel demand that may cause the country’s greenhouse gas emissions in fiscal year 2011-2012 to rise as much as 6.6 percent over the Kyoto Protocol 1990 benchmark year. Japan had pledged to reduce its annual average greenhouse gas emissions in fiscal years 2008-2012 by 6 percent compare to 1990 levels, but Japanese emissions have been running 510 million tons higher than the benchmark volume, or 2.1 percent more than the benchmark years. The nation has generated slightly more than one-tenth of its total energy requirements with nuclear power until last summer, when the country closed its 54 reactors in response to the nuclear crisis.
