Rhode Island is one of eight states that joined a pledge Thursday to put 3.3 million zero-emission vehicles on the road by 2025. The pledge comes just weeks after the state installed 50 charging stations.

The pledge calls for more infrastructure to support the millions of electric cars expected to hit the road in the next dozen years. Every car maker is working to have an electric car for sale by 2015, but auto dealers say charging stations are key to getting consumers behind the wheel.

By the end of the summer Rhode Island will have more than 50 charging stations for electric cars. Even with the new charging stations the state will still lag behind its neighbors.

The first one comes online next week, and through the summer more than 50 more will pop up across the state. That’s fewer than the 60-plus in Connecticut and more than 100 charging stations in Massachusetts, said Al Dahlberg who helped craft the plan.
