This report describes the steps needed to enhance environmental sustainability in freight transportation among Canada, Mexico and the United States. It was also prepared to stress the important link between environmental sustainability and an efficient, competitive, and secure freight transportation system throughout North America.
The report focuses on North-South (and equally, South-North) freight transportation between Canada, Mexico and the United States. The principal environmental goal examined was to find ways to reduce carbon dioxide (CO2) emissions, which account for 95% or more of all freight transportation-related greenhouse gas (GHG) emissions. Importantly, measures to improve the GHG performance and energy efficiency of the transportation sector also carry significant air quality co-benefits.
