Uber’s carsharing service UberPool has been used more than 1 million times in London since it launched six months ago, according to a report by The Telegraph.

The service allows Uber users to share their rides if they are going in the same direction. The fares are 25% cheaper than the typical Uber trip, says the report.

Since its launch, more than 700,000 driving miles have been saved compared to if the trips had been taken solo, Jo Bertram, Uber’s U.K. head, told The Telegraph.

“We’re really pleased so many Londoners have chosen to share their journeys in the first few months of this new service,” Bertram told The Telegraph. “Not only does carsharing save consumers money, it’s also good for our city as it means fewer miles driven and less air pollution.”
