Issue: Clean Engines
The American Trucking Associations' new sustainability program will expand the progress the trucking industry has made in the last quarter century to reduce its carbon footprint and its overall impact on the environment.
For example, a new diesel engine emits 90 percent less particulate matter and 50 percent fewer nitrogen oxides than an engine made 20 years ago. New regulations, which the industry supported, will eventually achieve a 90 percent reduction in nitrogen oxides, which are a major contributor to smog.
Clean trucks will deliver even greater benefits as the ATA sustainability program takes hold, thanks to limits on speed, reduced idling, and other program initiatives.
