SIAM bats against direct switchover to BS VI

Vehicle emission posing a major threat, primarily in Indian cities like Delhi


Society of Indian Automobile Manufacturers of India (SIAM), the apex body of the Indian automotive industry, has raised its voice against direct shifting to Bharat Stage VI (BS VI) norm  without adopting and skipping BS V emission norm.

SIAM warned that directly adopting BS VI emission norms could result in major safety issues. Basically, the fuels of both the BS V and BS VI are same, but the related technologies are differed from each other and should be developed sequentially and tested & validated in every stage that would take around 4 to 4.5 years time period.

This is one of the major reasons that led developed European countries to implement the Euro V norm and later shifting to Euro VI after systematic validation and standardization of the Euro V, which is equivalent to BS V.

SIAM’s caution comes at the time when oil marketing companies gearing to shift to BS VI norms directly from BS IV without adopting BS V. The oil companies, it is understood that, intend to do this primarily in a bid to avoid more investments on the technology advancement program. As per industry watchers, the cost could be around Rs 80,000 crore if BS V is adopted before shifting BS VI.

In a press statement, SIAM’s president Vikram Kirloskar said, “The industry, notwithstanding the lead time required, has proposed an accelerated timeline for introducing BS V norms to 2019 and BS VI emission norms by 2023, as against 2020 and 2024 proposed by the Expert Committee on Auto Fuel Vision & Policy.”

Shifting to BS V emission norms from from BS III norms itself enhances PM emission further by upto 90 percent from the Bharat Stage III level. Meanwhile, further upgrading to BS VI emission norms offers only 0-10 percent incremental advantage in PM emissions and it is not worth skipping the BS V stage while compromising the safety aspects.

Kirloskar said the SIAM’s proposal of advancing to BS V emission norms in 2019 and further to BS VI emission norms in 2023 is the best solution taking environment and safety into account.
