According to a recent research it was concluded that the air in Delhi was one of the most polluted in recent times. The Indian Government has paid attention to this report and has decided to make a few changes to the existing emission norms that are in place currently.
Now the Indian Government could skip the BS-5 stage and go directly to BS-6. There is very minor change between the two stages and skipping to BS-6 would make more sense than going through it normally. The oil companies would have to change a bit so that sulphur content emitted is lowered.
As of now in India oil companies and manufacturers adhere to the BS-4 norm. This is, however, not followed throughout India, only 33 cities of India follow the BS-4 norm. The other remaining cities across India still follow BS-3 standards.
According to previous guidelines the Indian Government would make BS-4 emission standard compulsory across India by 2017. Their goal was to introduce BS-5 and BS-6 as well in India, however, it would not come before 2020 and 2024 respectively.
It is estimated that the industry will spend roughly INR 50,000 crore, to upgrade to the new emission norm. Once India is at the BS-6 level, our vehicles will be on par with European Union that is currently adhering to BS-6.
Industry experts believe that there is no harm and it is relatively easy to skip a emission standard.
The automobile manufacturers possess the technical knowledge of skipping directly to BS-6. In a way it is good news as we will be on par with international standards of vehicle emission. The Indian oil companies will have to improve fuel quality within the country as well if BS-6 needs to be implemented.
