Uber’s goal is for all rides to be in zero-emission vehicles by 2030 in the U.S. and Canada.

Drivers using Uber’s app will receive discounts for charging their vehicles with bp pulse, the energy company’s EV charging business. “The two companies will also explore working together on convenience and fuel offers,” the press release said.

More than 4% of all trip-miles on the Uber platform in the U.S. and Canada during the third quarter of 2022 were completed by zero-emission vehicles, an Uber spokesperson said in an email. That represented a leap of more than 11 times compared to the first half of 2021.

The Uber spokesperson also said that electric vehicle uptake by drivers using Uber’s app in the U.S. is now eight times higher than that of drivers in the general population.
