In an email to customers late Thursday, CEO Dara Khosrowshahi said Uber Eats will promote black-owned restaurants on its app, and that the service will not charge delivery fees to those restaurants “for the remainder of the year.”

Uber will also offer discounted rides to black-owned small businesses “who have been hit hard by COVID-19,” though it did not add how much of a discount would be given.

“I wish that the lives of George Floyd, Ahmaud Arbery, Breonna Taylor, and countless others weren’t so violently cut short,” the 51-year-old CEO wrote. “I wish that institutional racism, and the police violence it gives rise to, didn’t cause their deaths.”

Khosrowshahi also pledged that Uber will continue to crack down on discrimination, harassment and racism on its platform, and will hold its users accountable “to these standards of basic respect and human decency.”

“I respectfully ask anyone not willing to abide by these rules to delete Uber,” he wrote.

Shares of Uber were up 3.5 percent early Friday afternoon, at $37.70.
