May 22, 2016 Fuel, pollution, emissions
The new rule for diesel and petrol called "Beijing Six" standards will cut car pollutants by an additional 15 to 20 percent in the city, Xinhua reported, quoting a researcher with Beijing's environmental protection bureau. In addition, China's "National Five" standard, equivalent to the Euro V specifications, will be implemented nationwide in January 2017.
The "Beijing Six" standards is a major upgrade from China's national five standards that are only used in more economically developed eastern provinces now. It allows a maximum sulphur content of 10 parts per million (ppm), and requires a lower level of other pollutants such as Benzene and PAH (polycyclic aromatic hydrocarbon) compared with Euro V specifications.
Diesel burning trucks and automobile emissions have been a major contributor to Beijing's persistent smog problem.
On 20 May, the municipal government said it would retire more than 400,000 trucks and mini buses in 2016 and 2017 that burn low-quality high-sulphur fuels.
