New Delhi: The national capital is facing a more serious pollution crisis from secondary particles, in addition to tiny pollution particles (PM2.5) being emitted from various sources like transport

The Society of Automobile Manufacturers (Siam) has welcomed Government's decision to move over to BS V emission norms by 2019 but said that BS VI in 2021/22 is unrealistic.

While the earlier plan was to implement BS-V by 2020 and BS-VI by 2024, the Petroleum Ministry sought to skip BS-V and directly implement BS-VI standards by 2020

India will implement the Bharat Stage-V, or BS-V, emission norms for vehicles across the country from 2019, the government said in a statement.

Directly aping Euro norms might be a problem considering the driving conditions peculiar to India that might require the adaptation of critical components to work in these conditions.

The transport department may put an end to registration of Bharat StageIII vehicles as a measure to tackle the rising air pollution in Delhi.

Manufacturers should strengthen their research and development activities to produce vehicles that are cleaner and more fuel efficient.
