A report published last Thursday on English.eastday.com said Shanghai Mayor Han Zheng called on the city to cut energy use per unit of gross domestic product by 20 percent from the 2005 level by 2010. His remarks were made during the city's energy efficiency work conference. The report said energy consumption per unit of GDP fell 16.5 percent between 2000 and 2005. According to the 11th five-year plan, this level should be cut by a further 20 percent. Go Shanghai!
