Beginning to appear more haze , vehicle exhaust is considered to be an important source of pollution. Yesterday, the NDRC issued the oil quality upgrade pricing policy to determine the gasoline and diesel fuel quality upgrade to "national four " increase 290 yuan per ton and 370 yuan ; "national four " rose "National Five-Year" increase 170 yuan per ton , respectively, and $ 160.
According to the  Throttle Valve Kero understand oil quality upgrade , according to the principle of competitive prices appropriately raise oil prices , reflecting the ' causer of pollution responsible ', more oil, more than the principle of burden . In recent years , in order to encourage local advance the implementation of oil quality upgrade , Beijing , Shanghai , Guangdong and Jiangsu provinces and lead in the implementation of the pilot policy at competitive prices , oil refining enterprises to accelerate the mobilization of the pace of upgrading the quality of oil played an important role , and achieved good results.
        Oil quality upgrade of technology is no problem, upgrade costs and the corresponding increase of oil is obviously the key to upgrading the quality of oil . Is still taken by the Government to determine the cost-plus oil increases , through CNPC , Sinopec has completed the transformation of refinery oil quality upgrade cost for review, in accordance with the refinery to digest part of the burden on consumers to determine the principle part of the standard published fare .
       The cost of environmental management through the " polluter , who is responsible" principle digestion is inevitable, sustainable choice, but the price policy needs to take into account the impact of different consumer groups . Therefore, the Government has proposed appropriate for agriculture, forestry, fisheries , urban public transport and other disadvantaged groups and public sector subsidies.

But some market participants worry that month to run 2,000 km of private cars , one hundred kilometers fuel consumption of 8 liters estimates, petrol upgrade the country four , the owners of Expenses will increase 425 yuan / ton, and may enter the " eight times ."

Price policy mode of operation is the ' unified announcement , decentralized implementation ', does not mean that the country will increase oil prices immediately . The state announced a unified standard fare , the specific operation to the local , from all over the local realities , you can save as a unit, the unit can also be free to determine the city oil quality upgrade process, and timely according to the state standards promulgated local fare fare policy .

The actual increase will be synchronized to the rhythm of the oil upgrade schedule, the transition period will end no later executed , while the upgrade is complete advance replacement great potential to advance the implementation of regional fare policy, which will increase the motivation to upgrade oil refinery .

       According Kero  Throttle Valve aware, the consumers, oil quality upgrade is a process, and its impact is a process, but also for consumers in different regions have different effects . From the amplitude , said Beijing , Shanghai and other regions of gasoline and diesel fuel quality upgrade from the second stage to the fourth stage, per ton , respectively, have been accumulated increase 410 yuan and 480 yuan, so the quality of oil in these areas to upgrade to the "National Five-Year" , plus price of 50 yuan per ton only , relatively little impact . While the other is still "national three " areas , consumers will be affected by the increase bigger . From the affected time to read , because the government only unified standard fare and oil quality upgrade start time , local governments will be combined with local conditions, to determine the oil quality upgrade process. Clearly, the Government's current focus on environmental governance areas, including Beijing, Tianjin , the Yangtze River Delta , Pearl River Delta , it will certainly walk in the forefront of the oil quality upgrade .
