UPS, Ryder, and PepsiCo’s Frito-Lay are the latest to demonstrate a commitment to operating their fleets more sustainably.

Three commercial fleets including UPS, Ryder, and PepsiCo’s Frito-Lay division—all members of Clean Cities’ National Clean Fleets Partnership (NCFP)—recently shattered their own sustainability goals by logging impressive mileage numbers with alternative fuel vehicles.

UPS recently announced it hit its goal of driving one billion miles in its alternative fuel and advanced technology fleet one year earlier than planned, while Ryder and PepsiCo’s Frito-Lay announced the 100-million mile achievement for their compressed natural gas (CNG) fleets.

UPS deepened its commitment to alternative fuels in 2012, when it set the goal of reaching one billion miles driven with alternative fuels by the end of 2017. Smashing that goal one year early, about 12% of the conventional diesel and gasoline fuel previously used by UPS’s ground fleet is now being replaced by alternative fuels including renewable natural gas and renewable diesel.

Through the deployment of its natural gas vehicle program, Ryder—a leader in commercial fleet management, dedicated transportation, and supply chain solutions—has displaced approximately 15.4 million gallons of diesel fuel since 2011 in addition to driving 100-million alternative fuel (AFV) miles. The company’s CNG fleet operations serve customers in 16 states and two Canadian provinces.

Frito-Lay first began leveraging CNG technology in 2011 when 16 CNG freight trucks went into service. Today, the Frito-Lay CNG fleet has also driven 100-million AFV miles and grown to more than 500 vehicles, representing more than 35% of the company’s long-haul inventory.

Each of the companies is also a founding member of the Clean Cities NCFP, which began in 2011. Since its inception, participants in the NCFP have teamed with Clean Cities coalitions across the country to implement strategies that reduce their greenhouse gas (GHG) emissions and petroleum use.

The initiative has left an impressive impact nationwide; in 2015, the partners’ efforts averted more than 369,000 tons of GHGs and displaced more than 152 million gasoline gallon equivalents of petroleum. Thanks to the partners, 101,677 alternative fuel and advanced technology vehicles have been deployed.
