It was learned from the Tianjin Environmental Protection Bureau that in 2014, Tianjin will strive to implement the national standards for gasoline and diesel, and has now formulated specific plans for oil upgrading. In response to the air pollution prevention measures and progress in Beijing, Tianjin and Hebei, Zhao Enhai, deputy director of the Tianjin Environmental Protection Bureau, said that Tianjin has already prepared for the accelerated upgrading of oil products, and plans to implement the national fifth-stage motor vehicle emission standards in advance. It is understood that in October 2013, Tianjin has been upgraded to the gasoline Euro IV standard, and diesel is still the national standard. To this end, diesel will "jump" directly to the country's fifth, no longer through the fourth phase of the country. According to reports, motor vehicle emissions are one of the important sources of PM2.5, improving the standards and quality of oil products, and helping to drive motor vehicle emission reduction. The data shows that the average oil product upgrade has reduced the vehicle emissions by an average of 15% to 20%. Previously, based on the consideration of air pollution prevention and control, Beijing has taken the lead in upgrading gasoline and diesel to the local standard equivalent to the national five, while Tianjin and Hebei only fully supplied the national standard gasoline for gasoline at the end of 2013. The upgrade in Tianjin means that the “oil product reunification†will be realized in Beijing and Tianjin, and it is expected to be realized by the end of 2014. According to previous national plans, the national gasoline and diesel schedule for the implementation of the national five standards is 2017. However, in view of the needs of the joint atmosphere control of the Beijing-Tianjin-Hebei region, the three places are coordinating with relevant departments and oil supply units, hoping that the pace of unification of Beijing-Tianjin-Hebei oil products will accelerate. In the 2014 motor vehicle pollution prevention and control program formulated by Tianjin, the contents of the oil product upgrade were also mentioned.
