The roll out of BS - VI fuel from April 1 next year in the national capital will bring down sulphur by 5 times from the current BS IV levels according to the Centre for Science and Environment.
In an emailed statement, CSE said, “This is a whopping 80 per cent reduction and makes this fuel extremely clean. This will improve emissions from the existing fleet, even from the older vehicles on road, while allowing more advanced emissions control systems to be fitted in BSVI vehicles when they begin to roll.”
However, the full advantage of this move will be possible only when vehicle technology moves to BSVI, the statement added.
