In an effort to reduce their businesses’ environmental impact, the state’s two leading telecommunications companies – Cox Communications and Verizon Communications – are both adding hybrid vehicles to their fleets of cars and service trucks.

The companies’ moves come as awareness grows about the environmental impact of public- and private-sector vehicle fleets. A recent survey found that 80 percent of fleet managers say there is growing interest in their fleets’ environmental impact at their organization, according to Utility & Telecom Fleets magazine, a trade publication.
