G&D Integrated has found that sustainability is not only about its own goals but also what it can do to meet its customers' goals to be environmentally friendly.

Biodiesel has been key to helping the carrier grow its business. For instance, biodiesel usage is showing up in some RFPs and has been "directly related" to G&D Integrated winning bids. It also has helped G&D Integrated strengthen its relationship with East Coast ports that want to reduce their carbon footprint.

The Illinois-based carrier operates a fleet of 430 vehicles and travels up to 26 million miles annually. The diesel-powered units run year-round on a blend of 20 percent biodiesel and 80 percent petroleum diesel, which is known as B20. Plus, G&D Integrated has experienced absolutely zero degradation in performance.

According to Vince Buonassi with G&D Integrated there's really no sense in fighting the tide of sustainability. "A lot of other truck carriers will. At G&D Integrated, we feel it is our duty to be good environmental custodians, and it makes business sense for us."
