BEIJING:- China said Wednesday it would extend the use of ethanol fuel nationwide as it seeks to intensify anti-pollution efforts while finding a use for its huge corn surplus. The plan will “support the use of ethanol fuel throughout the country by 2020” while strengthening the capacity of the biofuel industry, according to a document from the National Development and Reform Commission and the energy administration. At the moment, biofuels account for just one percent of the total petroleum products consumed in China , the world’s largest automobile market.
