In which year was the China IV standard implemented?
2 Answers
China IV was implemented on July 1, 2013. Below is relevant information about the China IV standard: Here are the specific implementation dates for some automotive emission standards: China III emission standard: The specific implementation dates were July 1, 2009 for light-duty diesel vehicles, July 1, 2010 for heavy-duty gasoline vehicles, July 1, 2008 for heavy-duty gas vehicles, and July 1, 2008 for heavy-duty diesel vehicles. China IV emission standard: The nationwide implementation dates were July 1, 2013 for light-duty diesel vehicles, July 1, 2013 for heavy-duty gasoline vehicles, January 1, 2011 for heavy-duty gas vehicles, and July 1, 2013 for heavy-duty diesel vehicles. China V emission standard: China V emission standard was fully implemented nationwide on July 1, 2017, with nitrogen oxide emissions reduced by 25% compared to China IV standard, and additional PM emission limits were introduced, making it more stringent.
I've been driving for over 20 years and remember that the China IV emission standard was officially implemented on July 1, 2010, primarily targeting light-duty vehicles. When it was first introduced, many cities started requiring new vehicles to comply with this standard for registration. I personally chose a China IV compliant car when I changed vehicles in 2011, noticing significantly cleaner emissions and lower environmental taxes. This standard upgraded pollution control measures, such as reducing carbon monoxide and particulate matter emissions, which greatly contributed to air quality improvement. Looking back, 2010 marked a major turning point in environmental policies - following the China III standard introduced in 2008, with heavy-duty vehicles catching up in 2013, collectively making the automotive market more eco-friendly. This posed challenges for existing vehicle owners as some China III compliant vehicles had to be retired or retrofitted, but long-term benefits included noticeably better urban air quality with reduced smog. Reflecting on it now, vehicles from around 2010 were indeed more advanced and provided a smoother driving experience.
