WASHINGTON (Reuters) -Vermont Governor Phil Scott paused the state's electric vehicle sales requirements for passenger cars and medium and heavy-duty trucks on Tuesday, amid broader concerns about the feasibility of zero-emission vehicle rules pioneered by California.

Vermont is one of 11 states including New York, Maryland and Massachusetts that have adopted California's zero-emission vehicle rules, which seek to end the sale of gasoline-only vehicles by 2035. California's rules require 35% of light-duty vehicles in the 2026 model year to be zero-emission models.
