BS6 exhaust norms in full swing, the implementation date is not far. All the hype about the new norms and the hard work put into the research and development has to lead the people to have many questions. One such question is Why did we skip BS5 in between BS4 and BS56? Did the government forget math?
First Step (2000)
The first emission norm restriction was put in 2000, it was called India 2000. During that time the IDC (Indian Driving Cycle) was also modified. The then implemented norms were equivalent to EURO1 stage norms implemented in Europe in 1992.
After the introduction of the first norms in 2000, after every couple of years, there was a change in the exhaust emission norms. Till 2005 the major changes were done and the changes in norms stopped. Here is a description of the norms and the year in which they were implemented.
| Emission Norms | Year of Implementation |
| India 2000 | 2000 |
| BS2 (BS ll) | 2003 |
| BS3 (BS lll) | 2005 |

Norms change after a decade (2017)
Till 2010 March BS3 norms were in power and all the vehicles on the road were complying with those norms. This resulted in an increase in the overall pollution in metro cities like Delhi. The government implemented BS4 norms from April 2010 but only for some metro cities. The then-new norm BS4 in 2010 was only applicable to 4-wheelers which constituted the most amount of traffic in the cities.
The next BS4 norms set a firm foot in April of 2017. Which started the nail-biting about the emission norms. These norms were confirmed and all the vehicled running on the road all over India had to follow these emission norms.

BS6 | The Big leap
The government noticed rising pollution especially in the metros over the years. As it took more than a decade in launching BS4 in the entire country. The government decided to skip one emission norm (BS5) to better be late than sorry. The Indian government gave ample time to fix the issues and develop new engines for the norms BS6 which are drastically low than previous BS4 emission norms.
We assume that the environment is the most precious thing we’ve got and is priceless. And saving our beloved environment by paying some extra premium on the BS6 cars is no price.
