After the initial uncertainty surrounding the implementation of China IV, as recently discussed by Integer in a website post, the government officially announced the next implementation date for China IV on 10 January 2012.
China’s Ministry of Environmental Protection (MEP) officially announced in a statement that the implementation of the China IV emission standard for heavy-duty diesel vehicles was delayed from January 2012 to 1 July 2013. This new implementation date is even later than many market players expected. The MEP stated that the reason for the delay was the lack of a nationwide supply of 350ppm diesel.
Some regions in China are ahead on nationwide standards and have already implemented higher fuel and emission standards. The Greater Pearl River Delta for instance already supplies 350ppm diesel and will implement China IV standards later this year.
Initially, the government agreed that for the implementation of China IV, diesel containing 350ppm of sulphur would be sufficient for the first few months. Diesel containing 350ppm actually corresponds to a lower fuel standard (China III, equivalent to Euro III). Usually, emission standards are implemented with the corresponding fuel standards. The required fuel standard for China IV would technically be China IV diesel containing only 50ppm of sulphur. It is unlikely however that 50ppm diesel will be available nationwide before July 2013. Therefore 350ppm will be marketed instead, once suppliers and the government can agree on financial incentives or price increases to market this type of diesel.
