Nowadays Vehicle traffic is increasing and the quality of air is affected by the smoke emitted by the vehicle. The government is yet to come up with an awesome plan that the pollution certificate of the vehicle is as mandatory as the license. License is to Driver, Pollution Certificate is to vehicle. If the pollution certificate is not there, the punishment is same as the driver without license. Therefore its a duty of all vehicle users to maintain the pollution certificate and co-operate with the government to reduce the pollution and save our environment.
All types of gaseous emissions from vehicles in excess of their allowable limits are called car pollution. Right? But we can’t blame only cars for this type of emissions. Buses, trucks, taxis, rickshaws, motor cycles, wagons etc all are equally contributing in increase of this menace. Even the emissions from aeroplanes, helicopters, jets, ships and motor boats can also be another form of vehicular emissions but their quantum is not as much as that of road transport therefore it is less focused while debating on this issue.
It does not mean every vehicle adds contamination in air. Only those vehicles pollute the atmosphere which emit harmful and poisonous gases more than the prescribed limits. What are these prescribed limits? These limits are set by environmental regulatory authorities of each country and are developed in view of health and environment safety.
Vehicles are driven by fuel which is burnt to create energy which eventually keeps the engine and wheels of a vehicle moving. Burning of fossil fuel would naturally emit smoke.So it is unwise to say that a vehicle should not emit altogether but stress is made on minimum emissions which could be offset by atmospheric pressures like flow of wind which can disperse the gaseous concentration and mitigate its intensity at one place.
Similarly regular tree plantation and greenery also improve the air quality of surroundings and remove the sources of negative health impacts from the atmosphere. Planning in construction of roads, highways, subways, bridges and bypasses is also an important factor to check the menace of car pollution. If roads are made spacious, highways carry several lanes, subways and bridges have minimum angular curves then traffic flow would not be disturbed and vehicles would emit less due to their smooth running as there would be no pressure on engine and silencer while running smoothly. Availability of comfortable and cheap public transport discourages the use of car for individual needs. In advanced countries public transport system is enviable but in less developed countries it is nothing but miserable. Hence why less developed cities like Mumbai, Karachi, Hanoi, Tehran etc are facing more load of vehicles on their roads and undergoing more pains from the menace of vehicular pollution. While cities like Beijing, Tokyo, New York, London, Paris are enjoying natural environment more because they have very advance public transport system both at roads and railways. Under public transport system less vehicles serve the travelling needs of more people as compared to personal transport. Use of adulterated fuel is also common in backward as well as least developed countries. Burning of adulterated fuel also emits more smoke which ultimately adds to the bad quality of air. Laws are there to control adulteration but their implementation is not stronger because of bad governance in such countries. A survey says one-third of this type of pollution could be reduced in least developed countries if use of adulterated fuel is literally banned there.
