China Manages to Cut Some Sulphur Dioxide Emissions

China, the world's top emitter of sulphur dioxide, has managed to cut emissions of the acid-rain causing pollutant in first half of 2007, but the government said on Tuesday that meeting national targets would be tough. China has promised to cut emissions by 10% between 2006 and 2010. Sulphur dioxide emissions were down .88% in the first half of 2007, Beijing said. China has offered higher tariffs to power stations with desulphurization equipment.
