VNG.CO has signed an agreement with Donlen that provides customers of the fleet management company access to VNG's network of compressed natural gas (CNG) fueling stations.

Donlen's commercial fleet drivers will be able to fill their vehicles with gasoline or CNG under the agreement, according to Donlen.

"By partnering with VNG.CO, we're providing resources that our customers need to successfully implement light-duty CNG vehicles in their fleet," said Amy Blaine, Donlen's vice president of consulting, analytics, and sustainability. "Now, in addition to providing analysis and vehicles that show customers where CNG makes sense for them, we're giving them access to a network of stations."

Natural gas offers cost savings and reduced emissions to fleet managers, according to VNG.
