?In a bid to reduce vehicular pollution, the West Bengal government is focusing on adding 2,000 electric buses to its fleet and also converting at least 3,000 diesel-run buses into CNG-powered vehicles in the next few years, state Transport Minister Firhad Hakim said on Sunday. Around 80 electric buses are currently plying the roads of Kolkata, Hakim said, adding that a pilot project for turning 30 fossil fuel-run buses into CNG-operated ones has been completed, and the results are encouraging. ?
