By 2025, New York City is planning to employ the largest municipal fleet of electric vehicles in the country, along with a sprawling network of charging stations to go with it.

Under a plan announced by Mayor Bill de Blasio on Tuesday, around 2,000 city-owned sedans, used by local agencies like the Transportation Department and the Parks and Recreation Department, would be replaced with electric vehicles like the Chevrolet Volt and Nissan Leaf over the next decade.

The city owns a total of roughly 11,000 sedans and sport utility vehicles, about half of which are used primarily for emergency purposes by the Fire Department and the Police Department.

The electric vehicles — a majority of which are expected to operate entirely without fuel — would make up about half of the city’s nonemergency fleet, officials said.
