Reducing the Environmental Impact of Large Commercial Trucks

In a consumer society, large commercial trucks are a fact of life. We see them on the interstate daily, bringing goods to market. What are some ways that truck owners and operators can minimize their environmental footprint?

Fuel Efficiency Is Key

Historically, commercial trucks have gotten terrible fuel mileage – as low as four or five miles per gallon in previous decades, rising to six or seven miles per gallon more recently. And their efficiency has not risen as much as passenger vehicles over the same time. But EPA regulations in recent years have set aggressive targets for reduced greenhouse emissions and increased fuel economy in commercial trucks. Truck, trailer, and tire manufacturers all have a common interest in providing fleet owners with more efficient solutions to reach these targets.

Aerodynamics and Rolling Resistance Are the Way to Get There

Along with engine efficiency, improving aerodynamics and reducing rolling resistance are important factors. At highway speeds the aerodynamic effects of better cab and trailer design, combined with skirts along the bottom of trailers and fold-out “tails” on the trailer doors, reduce turbulence and drag. The familiar dual-tire arrangement may soon be a thing of the past as the industry tries wider tires, so the 18-wheeler of today may become a “10-wheeler.”

Maintenance Pays Off in Efficiency and Safety

Sticking to a maintenance schedule for the suspension and drive train of tractors and trailers has obvious advantages.  The firestone convoluted air spring is just one of the thousands of parts that wear out and need to be replaced on schedule. Neglecting suspension parts also increases vibration, wear, and tear on the rest of the truck, which increases costs and the load on the environment. Braking action is also compromised if the suspension doesn’t keep the tires firmly on the road. Diesel engines are designed for longevity, but still require maintenance to achieve the fuel economy they’re designed for.

Biofuels Can Help Close the Gaps

Operators can both save money and further help the environment by using biofuels. Biodiesel products reduce the environmental impact because they are renewable and frequently sourced from recycled sources like used frying oils. Biodiesel products are also easier on the environment since they’re less toxic.

Reducing demand for goods delivered by truck will ultimately have to be part of reducing environmental impact, for a variety of reasons. But as commercial trucks will be a part of the landscape for the foreseeable future, improving efficiency and reducing emissions will be an important part of reducing their environmental impact.
