Uber Technologies Inc. wants to expand its zero emissions pledge to food-delivery and make the business environmentally sustainable, but Chief Executive Officer Dara Khosrowshahi stopped short of committing to do so by a 2030 deadline for its ride-hailing arm.

The CEO said in an interview that food deliveries Uber makes in Europe are typically carried on scooters and bikes, so it prioritized cars for its green ambitions.

"We wanted to start with our mainline mobility business, and then based on our learnings there, we will absolutely apply them to delivery as well,” Khosrowshahi said. "I don’t know if it’ll be included in the 2030 target, but we’re absolutely going to look to drive delivery to be fully green as well.”
