The federal Clean Air Act establishes national fuel emission standards, but also allows states to adopt unique fuel programs to meet local air quality needs. The combination of federal and state fuel programs is intended to balance the importance of standard fuel quality across the country with the need for sufficient flexibility to address specific air quality issues at the state or local level.
State fuel programs are sometimes referred to as "boutique." Twelve states have adopted their own clean fuel programs for part or all of the state. Most of these programs set lower gasoline volatility requirements than the federal standards, and most are effective for only part of the year. For more information on the twelve programs, please view the list of states with boutique fuel programs.
