Oil Products National Standard Delayed Impact on the Twelfth Five-Year Environmental Protection Standard

On September 19, the reporter learned from the interview that since July 1 this year, domestic petrochemical enterprises did not supply the country III diesel according to the standard, and they did not specify when they could supply the national III diesel, which directly led to the country having to postpone the implementation of the country. IV Diesel vehicle emission standards. The delayed implementation of refined oil GB will directly affect the completion of the 12th Five-Year National Environmental Protection Restriction Index.


Experts stated that China's current motor vehicle exhaust is an important source of nitrogen oxides in the atmosphere. Whether it is through the tightening of standards to reduce the emissions of new diesel vehicles, or through the replacement of exhaust emission treatment devices to reduce the emissions of diesel vehicles in use, the use of low-sulfur diesel oil is a necessary condition.


Yuexin Yan, director of the Laboratory of Vehicle Fuels and Additives at the Chinese Research Academy of Environmental Sciences, told reporters that delays in the ditching of the diesel country III standard and the delay of the national IV emission standard have affected the national energy conservation and emission reduction tasks during the “Twelfth Five-Year Plan” period. There can be no quantifiable predictions, but actual delays are objective facts and may even make it difficult to complete the “Twelfth Five-Year” environmental indicators. According to him, according to the national "Twelfth Five-Year Plan", the country's nitrogen oxides need to drop by 10% compared with the end of the "Eleventh Five-Year Plan," while motor vehicle emissions account for 30% of the total nitrogen oxide emissions of the country, including heavy-duty diesel vehicles. Ammonia emissions account for more than 70% of total vehicle emissions.


Tang Dagang, director of the Ministry of Environmental Protection's Motor Vehicle Sewage Disposal Monitoring Center, also stated that the national “Twelfth Five-Year Plan” has added a binding indicator of nitrogen oxide emission reduction. At the same time, the key areas of the joint air pollution prevention and control joint-venture will also set emission reductions related to emissions from motor vehicles, such as particulate matter and volatile organic compounds, as the binding targets for total regional emission reductions. To accomplish these environmental protection tasks, it is necessary to effectively mitigate the serious pollution brought by motor vehicles, and whether or not the refined oil discharge standards have been implemented on schedule has become a key factor affecting the overall situation. "China must implement higher standards for refined oil emissions as soon as possible, the sooner the better," Tang Dagang said.


According to report, data from the European Union showed that when the refined oil standard goes from Euro III to Euro IV, nitrogen oxides can be reduced by 30%; from Euro IV to Euro V, nitrogen oxides can be reduced by 43%; from Europe When V goes to Europe VI, the reduction of nitrogen oxides can reach 80%.
