Environment Canada has issued proposed regulations that would limit greenhouse gas (GHG ) emissions from heavy-duty vehicles starting in 2014 to align Canadian standards with U.S. GHG emission limits. They would set standards for carbon dioxide, nitrous oxide and methane emissions applicable to manufacturers and importers of a range of heavy-duty vehicles and engines, including large pickup trucks; short-and long-haul tractors; buses; and freight, delivery, service, and cement trucks.  

The proposed regulations are designed to provide compliance flexibility, including a carbon dioxide emission credit system that would permit heavyduty vehicle manufacturers and importers to generate, bank and trade emission credits. They would also provide additional credits for hybrid and electric vehicles, and for innovative technologies that reduce GHG emissions. Public comments are requested by June 13, 2012.
