Uber is launching an electric vehicle service that will allow users to request rides in electric vehicles.

The service, called Uber Comfort Electric, which is debuting in Los Angeles, San Francisco, San Diego and Dubai, features electric vehicles from Tesla and Polestar.

The rollout comes a year after Uber announced its partnership with Hertz to make up to 50,000 Teslas available for Uber drivers to rent by 2023. Polestar, a unit of Volvo, has also signed an agreement to supply Hertz with 65,000 electric cars over the next five years.

“As part of Uber’s global commitment to becoming a zero-emissions mobility platform by 2040, we’re continuing to take steps to help you go electric,” the company said in a statement.

Uber is also adding more features to its platform to offer incentives for drivers to switch to electric vehicles, including an EV cost calculator and a map showing where EV chargers are located.

The EV features are part of a suite of announcements Uber unveiled Monday. It also launched Uber Travel, which is designed to coordinate a rider’s car bookings for each leg of a longer journey.
