In an effort to help meet its corporate goals for renewable energy and reducing its carbon footprint, the United Parcel Service (UPS) will be deploying a 50-strong fleet of custom-built, all-electric, zero emissions delivery trucks. UPS is teaming up with battery-electric transportation technology company Workhorse to develop the vehicles.

According to Workhorse, the trucks will be plug-in and capable of covering up to 100 miles per charge, meaning they can be used continuously throughout the day and then recharged overnight. The hope is that the vehicles will be comparable in purchase price to fuel-based delivery trucks and will cost less for maintenance and upkeep.

The vehicles will soon be tested in a number of U.S. locations, mostly urban areas such as Atlanta, Dallas and Los Angeles. Large-scale deployment is currently targeted for 2019.
