The Tesla Model S is a zero-emission car, though it sells for $70,000.
Maryland is one of eight states partnering together to put more than three million zero-emission vehicles on the road in the next ten years.
The Multi-State ZEV Action Plan includes states from both the East and West coasts, and hopes to put 3.3 million such vehicles on roads by the year 2025.
To achieve that goal, the plan lists three actions: Building the market for ZEV's, providing consistent rules and tracking for the vehicles and improving the experience of those who build them and those who use them. Specifically, the governors want to increase the number ZEV government vehicles in each state's fleet.
Tesla Motors is probably the best known car maker of ZEV's. It's Model S car sells for almost $70,000. The BMW i3, this year's World Green Car Award winner, starts at just over $41,000.
The other states partnering with Maryland are California, Connecticut, Massachusetts, New York, Oregon, Rhode Island, and Vermont. All eight states have Democratic governors.
