According to a report from the Centre for Science and Environment (CSE), India is the only major vehicle producing country in the world without fuel saving standards for cars. More than 40% of the nations? oil and oil products are consumed for running vehicles, but no serious efforts towards evolving a fuel saving roadmap for the transport sector have been made. If this consumption continues unabated, it could nullify gains of fuel savings from all other steps, and undermine all efforts at reducing climate change risks. The bus sector is already facing enormous fuel cost burden because of worsening fuel efficiency of buses. While CNG bus fuel efficiency in Delhi is stagnating, diesel bus fuel efficiency in other cities like Bengaluru is also worsening. The indecisiveness on car fuel conservation standards is delaying defining standards for other vehicle segments like buses.
