Owners of Tesla electric vehicles in Shanghai can reportedly now register them for free -- instead of paying the typical $12,000 fee for a license plate. That's part of Shanghai's efforts to encourage the adoption of new-energy vehicles, according to a vice director of the municipal government's economy and information commission cited by Bloomberg, which also reported that Tesla is in contact with other cities to get exemptions. The Model S is already exempt from registration tax in Hong Kong. China is taking steps to fight pollution through an action plan released last year by the state council. The plan includes targets for vehicle emissions control like phasing-out heavily polluting vehicles and cleaner gasoline and diesel availability by 2017.
