Dubai has added 50 Teslas to the city’s taxi fleet, part of a green economy initiative.

While it may seem like a surprising choice for a city that was built on oil revenues, fossil fuels now represent less than 5 percent of Dubai revenues. The rest now comes from real estate, trade, and the growing tourism sector.

The 50 Tesla taxis, made up of Model S and Model X vehicles, are part of a directive from Sheikh Mohammed bin Rashid Al Maktoum, vice president and prime minister of the United Arab Emirates and Ruler of Dubai, to make the city into the smartest in the world. The city wants 25 percent of all trips made to be driverless by 2030, and the Teslas’ self-drive technology plays a part in that goal.

The 50 Tesla taxis entering into service with the Dubai Taxi Corporation are part of an order of 200. Another 75 are expected to be delivered next year, with the rest following the year after.

While Dubai might be better known in the car world for a fleet of exotic police cars, the Tesla limo fleet, as well as the network of chargers to support it, is part of the city’s green economy initiative. The UAE has established a $27 billion green energy fund to support local and international green projects like this one.
