People’s Daily. New vehicles on sale in the Shanghai area must meet the China IV emissions standard—based on the Euro 4 emissions standards—beginning at the end of 2009.
China is phasing in more rigorous emissions standards, with China IV due to go into effect nationwide in July 2010 for light-duty vehicles and in January 2010 for heavy-duty vehicles. Beijing has been on an accelerated implementation path, requiring China IV for light-duty diesels in January 2007; for light-duty gasoline vehicles in March 2008; and for heavy-duty vehicles in January 2008.
Shanghai is now accelerating its implementation of the requirements, with an eye toward the upcoming 2010 Shanghai Expo.
