Entrepreneur Tony Verb is on a mission to promote technology that can help make cities greener and smarter in China's Greater Bay Area, now being shaped as a low-carbon megalopolis.

Hong Kong-based Verb, co-founder of the investment firm GreaterBay Ventures & Advisors, plans to back urban tech businesses working on autonomous e-vehicles, flying taxis, artificial intelligence, robotics and clean energy.

Verb is betting on China's master plan to develop the Pearl River Delta into a sustainable innovation hub, which he believes will serve as "a great case study" for the world's cities.
