As part of the Global Climate Action Summit, which brings together a variety of parties to discuss climate action opportunities, self-driving car startup Zoox is offering autonomous rides in San Francisco this week.

The company has partnered with the Fairmont hotel in San Francisco to transport select summit guests between the Fairmont and Moscone Center in Zoox’s self-driving Toyota Highlander test cars. Guests that ride in the cars will be determined by Zoox, Fairmont and the Summit.

The objective of the tests is to showcase the potential of Zoox’s zero-emission autonomous technology—which hasn’t been fully realized yet—to guests.

“Zoox was born to improve safety, congestion, and pollution in our increasingly dense cities,” says Zoox co-founder, President and CTO Jesse Levinson via TechCrunch.

“We are proud to demonstrate our state-of-the-art autonomous technology, partner with the Fairmont, and show private enterprise support of Governor Brown’s and Mayor Bloomberg’s Global Climate Action Summit right here in our hometown.”

Zoox’s goal is to commercially deploy autonomous vehicles by 2020. All-electric and fully autonomous, the cars would be a part of Zoox's own ride-hailing service.
