The Central Pollution Control Board (CPCB) on Tuesday suggested phasing out of commercial vehicles of over 15 years in use from city roads for effective control of pollution.
CPCB member-secretary B Sengupta today said at a seminar in Kolkata that despite new vehicles having met stringent pollution control norms, pollution was rampant mostly because of the plying of commercial vehicles.
Phasing out of over 15-year-old vehicles is part of a City Air Quality Action Plan framed by the CPCB which is abided by state governments.
West Bengal is one of the 35 state governments which have submitted their own action plans, but remained short of implementing them.
The action plan includes phasing out of vehicles of 15 years and above vintage, augmentation of mass transport system and switching to eco-friendly fuel LPG/LNG for two-three-wheelers.
Meanwhile, Sengupta said that the department was working closely with different agencies to see whether introduction of EURO-IV or Bharat IV norms before the deadline of 2010 were feasible.
West Bengal Pollution Control Board has commissioned a project to reduce pollution in the SSI sector as well.
