China is to introduce new vehicle emission standards by the end of next year, state media reported. Pei Xiaofei, an official at the Ministry of Environmental Protection, said the government was now formulating its sixth set of standards, the state-run news agency Xinhua reported. Curbs on pollutants such as nitrogen oxide and particulates in vehicle exhausts will be 30 per cent tougher, Pei was quoted as saying. A consultation exercise on the new standards will be completed by the middle of next year, the report said. Pei said the adoption of China’s fifth set of emission standards was progressing well. They are roughly equivalent to standards adopted in Europe in 2009, according to the report. All vehicles across the country have to meet the fifth set of standards by 2017. Beijing, Shanghai, Nanjing and some cities in Guangdong have already enforced the China V emissions standards, with Guangzhou due to comply by the end of the year, the report said. Vehicle exhausts have been identified as one of the big contributors to urban pollution in China.
