FedEx introduces hybrid electric delivery vehicles, while UPS is investing in fuel cell technology. - Late last month, the package delivery companies FedEx and UPS announced steps they are taking to reduce their energy consumption and carbon emissions. FedEx collaborated with Environmental Defense, a nonprofit organization, to introduce a low-emission hybrid electric powered delivery vehicle that could become the standard medium duty delivery truck in FedEx's fleet. Meanwhile, UPS announced a joint project with the U.S. Environmental Protection Agency and DaimlerChrysler to develop and later deploy zero-emission, fuel cell-powered vehicles.
