BS IV – The dawn of a new Era

Anyone who bought a new vehicle on March 31st would have known the satisfaction that comes from bargaining for a brand new vehicle in a showroom flooded with people racing to buy a vehicle. However, the picture is not rosy for vehicle manufacturers and dealers as it is for the customers. Retailers and manufacturers had to settle in for a relatively paltry sum which is something that they are not used to. Although it may appear as if the customers are the ones who gained from it, it is not actually true. In fact, with the ban on BS III vehicles, the entire population in India has got something to gain although not economically.

Why is it banned?

India’s automobile industry is one of the largest in the world with a production of around 24 million vehicles annually. It is one of the single largest contributors to the Indian economy with a 7.1% share of the GDP of the country. Though the figure is a sign of development in the economy, the automobile industry had been doing more bad than good. Previously, automobiles in India were manufactured in such a way that they were Bharat Stage III compliant.

It contributed to pollution which has drastically reduced the air quality in several regions of the country with some places finding a place in most polluted cities in the world. To prevent further deterioration of people’s health the Supreme Court has taken a bold move by banning the sale and registration of new BS III vehicles which amounted to 8.24 lakh vehicles. However, BS III vehicles can be used and sold in the second-hand market. Although vehicle manufacturers were ready to migrate to BS-IV vehicles even in the year 2010, the lack of low sulphur fuels prevented it thereby delaying the whole process.

How are BS-IV vehicles any different from BS III vehicles?

The difference between BS III and BS IV vehicles is in the standards that they follow. Indian BS standards are based on European Regulations and the first BS standard was adopted in the year 2000. Since then the standards have been becoming progressively stricter. The main difference lies in the quantity of carbon monoxide (CO) and Hydrocarbon, Nitrous oxide (HC+NOx) emitted by the vehicles. BS-IV vehicles emit 0.75g/km while BS III vehicle did 1g/km of the chemicals. This makes BS IV compliant automobiles efficient.  Now, the automobiles in India are expected to pollute less and transport more.
