In March 1, 2012, the guidelines for evaluation of air quality in passenger cars began to be implemented in China. According to the analysis of the types and sources of volatile organic compounds in the air and the volatilization characteristics of the main interior materials in the vehicle, the guide has determined 8 main controlled substances, which stipulate the concentration requirements of benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in the air of the car. People in the industry have been optimistic that the guide has filled the blank of the air quality standards in our car, making the air inspection in the car finally standard, which will promote the manufacturers to pay attention to the air quality in the car and greatly improve the quality of the air in the passenger car. However, this good wish has fallen into the void. Because the guide is only a recommended national standard, not a mandatory standard. That is to say, enterprises will not get any benefits even if they increase the cost and improve the quality of the air in the car. Enterprises continue to have no concern for the bad air quality in the car, and no fear of being fined by the state. In addition, some enterprises put into cost to improve the quality of the air in the car. Some are not doing the same. The result is the same. The increase in cost reduces the competitiveness and profit of the product. Under such circumstances, how many enterprises will take the initiative to improve the air quality inside the vehicle? There are no lack of such examples in the car industry. Some car companies know that their products have quality problems, knowing that they will be fined by the state, and they will still prevarication. There are mandatory regulations, and there is no mandatory standard. It is even more difficult to ensure that the guide will not be empty. For example, in September 2012, 6 months after the implementation of the guide, 300 owners complained about the 4 times the formaldehyde emission of a brand car. Also in September, a "healthy car test report" showed that the 11 mainstream models may cause cancer risk and finally become unfinished news. Therefore, many domestic industry people appeal for mandatory standards and improve relevant laws and regulations. Among them, Li Shufu, the chairman of the Geely Automobile, has repeatedly suggested that the guide to the evaluation of the air quality in the passenger car should be transformed into a national compulsory standard as soon as possible, and the national environment and health policies and regulations based on prevention should be established and improved. "All along, the domestic air quality in the car is not regulated, no standard, no regulation. Many owners can only endure the smell of new cars. The smell of new cars has become a helpless expression of air pollution inside cars. It is suggested that the state set up an authoritative air quality inspection and release agency in passenger cars, and regularly publish the air quality of the new car on the market, so that consumers will have the right to know the air pollution in the car. " Li Shufu said. In fact, the cost of improving vehicle air quality costs is not high in the whole automobile production cost. Last year, the survey carried out by 22 domestic consumer protection units jointly with the Beijing Institute of Labor Protection Science showed that the air quality in the car was not directly proportional to the price. Some of the high - priced brand cars have poor air quality, and some of the best - selling high-end products even exceed the standard acetaldehyde. On the contrary, most of the economic models have excellent air quality in their cars. Liu Jinliang, vice president of the Geely car, said that, in order to improve the air quality, Geely added 200 yuan to every luxury car to improve the air quality, adding a process to remove the odor in the car. This shows a reason that improving the air quality inside cars is not impossible for car companies, but not for them. The only way for all manufacturers to take the initiative to improve the air quality inside the vehicle is to turn the guide into a mandatory standard. In the continuous fog and haze weather, consumers have already suffered too much. If the air quality in the vehicle is still not regulated by law, it will be a tragedy for the whole Chinese automobile industry. In 2013, we not only yearn for the blue sky, but also yearn for the fresh space in the car.
