OTTAWA -- Ottawa is introducing new fuel consumption ratings and labels for cars and trucks.

Federal Natural Resources Minister Joe Oliver says the new ratings will provide consumers with a more accurate reading of a vehicle's fuel efficiency by taking into account factors such as cold weather, air conditioner use and rapid acceleration and braking.

The government will also publish a list of the most fuel-efficient vehicles this year, which will include a online searchable database where consumers can go for information on different vehicles.
