AT&T Inc. announced plans to add 105 alternative-fuel vehicles to the corporate fleet of its operating companies. The vehicles, which will roll out in more than 30 cities across the United States beginning in June 2008, will help the company reduce its impact on the environment and its dependence on imported oil.

After carefully evaluating several alternative-fuel technologies, AT&T will deploy three types of alternative-fuel vehicles. The vehicles will be embedded into AT&T's workforce as operational components of its fleet. AT&T will measure and track fuel efficiency, greenhouse gas emissions, operating costs, performance, and driver satisfaction of each vehicle.

The alternative-fuel vehicles consist of 25 compressed natural gas (CNG) vans, 65 electric hybrid original equipment manufacturer (OEM) vehicles — Ford Escapes and Toyota Priuses — and 15 electric hybrid conversion work trucks. The vehicles, which will be deployed in cities in California, Florida, Georgia, Illinois, Indiana, Michigan, Missouri, Ohio, and Texas, join four Ford Escape hybrids that were deployed in California in late 2007.

AT&T estimates its use of these alternative-fueled and more fuel-efficient vehicles will reduce greenhouse gas emissions by 124 metric tons and conserve nearly 34,395 gallons of fuel annually.

The CNG vans are expected to reduce greenhouse gas emissions by nearly 30 percent compared with traditional gasoline vans. The electric hybrid OEM vehicles are expected to offer a 39 percent improvement in fuel economy and reduce greenhouse gas emissions by 29 percent. The electric hybrid conversion work trucks are expected to offer a 38 percent improvement in fuel economy compared with similar gasoline-powered vehicles and reduce greenhouse gas emissions by 28 percent.
