The Greening of the Fleet: Info-graphic illustrates one of the most important environmental success stories in a generation

TUSCALOOSA, Ala., April 22, 2013 /PRNewswire/ -- In less than two decades, exhaust emissions from diesel trucks and heavy equipment have been cut by more than 95 percent – one of the most successful environmental initiatives of our time.

How was it done? A combination of engine technologies:

  • Improved diesel fuel injection
  • Computerized engine controls
  • Advanced engine air management
  • Sophisticated exhaust filters and
  • A lowering of the sulfur content of diesel fuel from 3,000 parts per million to less than 15 ppm.

Today, virtually all new on-highway trucks use these clean-burning diesel engines and by 2014 all off-road diesel engines under 750 horsepower will also meet the new emissions regulations.

Numbers alone won't do justice to this story, so the editors at Randall-Reilly have put together an info-graphic to tell the world just how clean today's heavy equipment and trucks are. A few examples:

  • Today's on-highway diesel trucks produce so few emissions that grilling a few hamburgers creates more air pollution than driving a truck.
  • In off-road equipment particulate matter, in-diesel exhaust has been reduced 97 percent, from 0.54 grams per brake horsepower hour in 1996 to 0.02 g/bhp-h in 2011.
  • By 2014 nitrogen oxides (NO2) in off-road engines will have been reduced 96 percent, from 9.2 g/bhp-h to 0.4g/bhp-h.
