A push to increase zero-emission cars has seen eight US states set ambitious targets of 3.3m EVs
and plug-in hybrids
on the roads by 2025, an exponential increase on today's numbers, with collaborative infrastructure development near the top of the priority list. The pact, signed by California, New York, Massachusetts, Maryland, Oregon, Connecticut, Rhode Island, and Vermont, aims to consolidate pro-EV legislation, public charger roll-out, and other elements, "to make it easier for customers to operate and use zero-emission vehicles" according to California Air Resources Board chair Mary Nichols. However, auto makers have already warned that waning subsidies and tax credits could see the cost of zero-emission vehicles rise by up to $4,000.
