Control of motor vehicle emissions: The environment has not been saved

From 1.7, cars circulating in 5 major urban areas of Hanoi, Ho Chi Minh City, Da Nang, Can Tho and Hai Phong will have to comply with the new emission standards. This move is in the roadmap to reduce motor vehicle emissions to protect the environment. However, with 16 million motorbikes (accounting for 96% of the country's motor vehicles), every day also discharges a volume of emissions no less than the emissions from 600,000 cars in circulation, it still lies out of control.

The amount of emissions discharged into the environment from 16 million motorcycles is still out of control.

From July 1, 2006, cars with control boards of 5 cities in Hanoi, Ho Chi Minh City, Hai Phong, Da Nang and Can Tho must meet the level 1 emission standard.

With gasoline engines, the maximum allowable limit of emissions is no more than 4.5 CO, no more than 1,200 ppm with 4-stroke engines, 7,800 ppm with 2-stroke engines and 3,300 ppm with special engine construction . For diesel engines, the limit is no more than 72% HSU.

This substandard vehicle will not be issued with environmental technical safety certificates by the registration stations. Cars of other localities must apply this standard on July 1, 2008.

The application of new exhaust standards with cars in circulation will minimize harmful emissions into the environment. But there are still many shortcomings.

The environment is cleaner

From 1.7 to apply new emission standards, although not significant increase (CO concentration from 6 to 4.5) and still far from the standards of advanced countries, but also 7-8% of cars dropped Register for smoke. Even expensive cars, new ones, and vehicles used by foreigners living in Vietnam were dropped because they did not meet the new emission standards.

It can be said that with higher emission standards and strict control barriers, it is clear that the environment will be cleaner. Gradually raising emission standards is also a right direction to protect the urban environment.

According to the current economic growth rate, cars will be more and more, especially in big cities. Creating a standard of emissions management and environmental pollution prevention is being carried out according to the roadmap and initially has a good effect.

In 2004 and 2005, many expired vehicles were removed, reducing a large amount of harmful emissions to the environment and also a stepping stone to the application of higher emission standards in urban areas. 1, proceed to apply nationwide.

However, many car owners in the above five cities said that it is not fair to circulate in these 5 cities, there are often a large number of cities and provinces not yet implementing new emission standards. . These vehicles have the full right to discharge the gas according to the old standard without dropping the register.

There will be a situation of vehicles registered in five major cities but returning to other provincial registry stations to avoid high emission standards. This concern has been anticipated by VCA and requires registration stations to check the vehicle registration area and inspect the vehicle according to the local emission standards to be certified. If fraud is detected, the department will handle it strictly.

A big problem is that not only cars discharge exhaust gas into the environment but also motorcycles. Currently, there are 16 million motorbikes nationwide (accounting for 96% of the circulation of motor vehicles), while there are only about 600,000 cars.

On average, a car with a cylinder capacity of 2.5 liters, and a motorbike of 0.1 liters, 25 motorcycles would be equivalent to a car. Thus 16 million motorcycles will also discharge an emissions of about 640,000 cars. Not to mention in urban areas, motorcycles will have more time to roll because they are the mobile means of the people.

Images of old and worn motorcycles, black smoke and blindness are not difficult to encounter in the present urban areas. Meanwhile, this emissions has not been controlled and there is no roadmap for removing old cars.

Moreover, the number of motorcycles is constantly increasing while the quality is getting lower and lower. Chinese motorbikes for only a few million VND, unsightly and durable engines will be a potential source of pollution in the future.

Perhaps it is time for managers to find appropriate control measures to minimize harmful emissions from motorcycles and protect the environment thoroughly.
