States' registration plans could accelerate electric vehicle adoption

Environmental experts say state proposals that set a 2030 goal of registering only electric vehicles could spur more people to adopt clean cars.

Last month, Washington Gov. Jay Inslee signed a climate change legislative package that included a goal to have every passenger car registered or sold in the state be an electric vehicle starting in 2030.

Other states may be following Washington's lead.

Rhode Island introduced a bill last month that also set a 2030 goal for 100% EV registrations in the state. Lawmakers in Hawaii previously introduced a bill that would mandate new model vehicle registrations be EVs starting in 2030.

Environmental experts told ABC News that while Washington and other states that set the 2030 registration deadline face uphill battles, including creating a strong charging infrastructure, their legislative moves could have a major impact on the rollout of EVs in the country.
