  • Use of public transport or carpool wherever and whenever we can help in reducing the overall environmental greenhouse gas emissions.
  • By using public transport, greenhouse gas emissions can be cut by more than half.
  • Carpooling is when several people travel together by car and share the cost of the journey. A once-a-week shift to carpool can reduce a commuter's carbon footprint by 20 per cent.
