Why Implementation of BS IV & Removal of BS III is getting delayed

Starting from 1st April 2017, the Supreme Court of India banned the sale of vehicles that do not comply with the BS IV emission norms as set by the Indian government. Indian government has set a set of rules and regulations as far as the pollutants released from the exhaust system of an internal combustion engine are concerned. These rules are represented by the Bharat stage emission standards.

These standards are based upon the European standards for example EURO 1, EURO 2, EURO 3, EURO 4.

Just to give you a brief idea about the numbers behind Bharat stage it simply means that as the number goes higher, the restrictions put on the vehicles become stricter. This is done because of the rising levels of pollution and global warming. Recently in India, there has been an explosion in the number of vehicles on road. To reduce the pollution caused by the vehicles, some governments, like recently, Delhi government launched a scheme called the odd-even scheme. Under this scheme, the vehicles which had even number license plates were allowed to run on the roads on even days and on the alternate days the vehicles which had odd numbers on in their license plates were allowed on the roads.

Despite the benefits of the Bharat stage emission regulations, there are still a lot of problems that need to be addressed, for example, the auto companies who manufacture the vehicles, whether it be to be two wheelers, four wheelers or trucks need to prepare beforehand to get rid of all the previous stock and then come up with the new technology which is compliant with the new set of norms.

Talking about BS 4 norms, the government has given notice to all the auto manufacturers that these norms shall be applicable from 1st of April 2017. Most of the auto companies have changed their manufacturing processes in order to comply with this. However some are still not happy with the change as this has led to a rush to letting go of their previous BS3 stock vehicles. Yesterday every BS3 made bike had some sort of discount to attract the public to buy these vehicles in order to minimize the company’s losses. The Society of Indian Automobile Manufacturers told the court that some companies were still holding a stock of around 8 lakh vehicles which were only BS3 compliant. Out of these 800000 vehicles, 96000 are commercial vehicles, 40000 three wheelers and over 6 lakh two wheelers.

It’s not just the engine that needs to be redesigned to meet the new norms but such engines require cleaner fuel in order to minimize the pollution. According to a report, the central government has spent about Rs.18000 to 20000 crores to produce a cleaner fuel. Now what does this mean for a common man who is not a car manufacturer? It simply means that you might have to pay a little more for the new vehicles which are BS IV compliant as the investment behind such technology made by the companies were huge and prices are bound to spike.

By 2020 the Indian government is planning to implement BS VI emission regulations. The BS 5 regulations will be skipped. This is all being done in order to reduce the pollution and improve the air quality across the whole country.

It might feel a little inconvenient at the moment for the common people and the auto manufacturers, but it is for the greater good.
