United Parcel Service (UPS) has added an additional 200 hybrid delivery vehicles to its fleet of low-emissions and alternative energy vehicles. With this latest addition, UPS now has more than 20,000 green vehicles in its fleet! The 200 new HEV package cars are expected to reduce fuel consumption by roughly 176,000 gallons over the course of a year compared to an equivalent number of traditional diesel trucks. The hybrids also should reduce by 1,786 metric tons the amount of CO2 gases released annually into the atmosphere.
