India's government is expected to officially reveal stringent fuel efficiency standards that will go into effect in 2015. According to the Hindustan Times, India's Corporate Average Fuel Economy (CAFE) standards will require automakers to increase fuel economy of gasoline-burning vehicles from the current average of 14.1 kilometers per liter (33.2 miles per gallon U.S.) to 17.3 km/liter (40.7 mpg U.S.) by 2015. In addition, automakers will be required to boost the average fuel economy rating of diesel-burning vehicles from the current level of 36.6 mpg to 46.8 mpg by 2015. Within the new guidelines, vehicles will supposedly be labeled with one to five stars depending upon their overall fuel economy rating.

The Hindustan Times explains that India's:
Draft fuel efficiency standard, based on CAFE, will be notified in May. The draft standard will be CO2 emission of 135 grams per kilometer for entire fleet in 2015. In 2010, the average CO2 emission was 165 gm/km. The draft also provides for further improvement by 2020.
Apparently, some environmental organizations want even stricter standards. For example, Anumita Roy Chowdhury, associate director at India's Centre for Science and Environment, wants India to follow Europe's lead by shooting for 110 g/km of CO2 emission by 2020.
