Uber is immediately expanding its "Green" program to new cities and setting a longer-term target of having fully electric cars account for 100% of rides on its platform in the U.S., Canadian and European cities by 2030. Why it matters: Those plans — and other new climate pledges Uber unveiled Tuesday — come as ride-hailing firms face growing scrutiny over their carbon emissions amid evidence they're cannibalizing public transit and increasing congestion.
