Tiny Grains of Rice Hold Big Promise for Greenhouse Gas Reductions, Bioenergy

ricecomparison.jpg

Rice is the staple food for more than half of the world’s population, but the paddies it’s grown in contributes up to 17 percent of global methane emissions -- about 100 million tons a year. Now, with the addition of a single gene, rice can be cultivated to emit virtually no methane, more starch for a richer food source and biomass for energy production, as announced in the July 30 edition of Nature and online.

Economic Slump, Not Natural Gas Boom, Responsible for Drop in CO2 Emissions

The 11 percent decrease in climate change-causing carbon dioxide emissions in the U.S. between 2007 and 2013 was caused by the global financial recession – not the reduced use of coal, research from the University of California Irvine, the University of Maryland, and the International Institute for Applied Systems Analysis shows.
