Eight states on the East and West coasts released a plan Thursday for working together to put 3.3 million zero-emission vehicles on the nation's roads by 2025.
The so-called "action plan" follows last year's memorandum of understanding announced by the governors of the states, including California and New York.
The other states in the pact are Massachusetts, Maryland, Oregon, Connecticut, Rhode Island and Vermont. The states represent about 23 percent of the U.S. auto market.
