Canadian Environment Minister Peter Kent on Monday announced final regulations to reduce greenhouse gas emissions for trucks and buses in the country that will mirror those set to go into effect starting next year in the Untied States.

The regulations will establish progressively more stringent standards for 2014 to 2018 model-year heavy-duty vehicles such as full-size pick-ups, semi-trucks, garbage trucks and buses.

The regulations will remain in full effect for all subsequent model-year vehicles, which will be required to adhere to the 2018 standard.

In a statement, the ministry said the move will result in GHG reductions of 19.1 megatonnes (21.05 million U.S. tons) over the lifetime of the 2014-2018 model-year vehicles.

The announcement was made at the Mississauga, Ontario, terminal of Canadian carrier Bison Transport.

Some in trucking in the United States have attacked the greenhouse gas regulations, saying they come on top of federal rules that have pushed the price of trucks dramatically higher the past few years and will make them even harder to afford.

Supporters say because the GHG rules are being coupled with the first ever fuel economy standards for U.S. commercial trucks, fuel efficiency will be better and owners will save money in the long run.
