With more than 300 billion miles traveled each year, the trucking industry leads on vehicle emission reductions and environmental sustainability.

It would take 60 of today’s trucks to generate the same level of NOx and soot emissions coming from a single truck back in 1988.

Recent research on the subject found that proposals for bigger trucks could lead to an increase of as much as 600 billion ton-miles of truck traffic, resulting in an additional 4.27 billion gallons of fuel burned and 55.58 million tons of carbon emissions.
