The Canadian government is suspending proposed greenhouse gas (GHG) emission standards for trailers for another year. American standards, on which Canadian standards are based, remain blocked.

The most recent restraining order was published in Canada Gazette Part 1 on April 1 and replaces an existing restraining order that would have expired on April 19.

Under the proposed regulations, trailer manufacturers would have to introduce fuel-saving technologies such as side skirts and automatic tire pressure monitoring systems. However, the United States Court of Appeals for the District of Columbia ruled that the Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) could not enforce such rules south of the border because trailers were not “motor vehicles”.

The rules were originally scheduled to take effect in January 2020, but have been challenged by the US-based Truck Trailer Manufacturers Association.

Other projects on our side of the border were mentioned in a letter from Stéphane Couroux, director of Environment and Climate Change Canada’s Transportation Division, distributed by the Transportation Equipment Association of Canada (TEAC).

“In the coming months, the department will continue to conduct further consultations with stakeholders, continue to closely monitor the situation in the United States following the Court of Appeals’ decision to overturn the trailer standards established by EPA and NHTSA, and continue to assess the implications for Canada,” said Couroux.

“This will help us make a final recommendation on how to proceed on trailer standards in Canada. »
