Electric vans are set to be used by South Yorkshire Police and will save the force more than £100,000 over the next four years.
The maintenance and driver services team will begin using the fleet of 12 Nissan e-NV200 vans later this Spring.
The move follows a push by Highways England to reduce emissions around the M1.
Sarah Gilding, head of Vehicle Fleet Management at South Yorkshire Police, said: “The Energy Saving Trust delivered five vehicles to us on behalf of Highways England. After taking delivery of the vehicles last September it quickly became apparent that the electric fleet was going to bring considerable benefits to the force.”
She added: “With just the electricity cost to meet, but no fuel bills and reduced maintenance costs to pay, it makes sound financial sense.”
The new vehicles will save the force approximately £118,800, as well as 296,626 kg in carbon dioxide emissions, over the next four years.
Christopher Plumb, Air Quality Programme Manager at Highways England, said: “The project is helping us to understand the barriers to using electric vans on our network, and to see if there are ways of helping others like South Yorkshire Police to switch across to electric vans.”
