Alternative Fuels
Applies to:

All vehicles; future standards may specifically affect vehicles powered by alternative fuels.
Requires:

Current standards set minimum fuel efficiency and maximum emissions standards for gasoline and diesel vehicles.

    Diesel Fuel Requirements (Marine)
    Applies to: All vessels registered in any of over 150 countries (including the U.S.) that are signatories to the MARPOL agreement.
    Requires: Sulfur content of fuel must be below a specified maximum. Special rules apply when operating in designated geographical areas.

    Engine Emissions (Auxiliary Marine Engines in Port)
    Applies to: Vessels visiting California ports
    Requires: Vessels must turn off auxiliary power generators and switch to land-based power while in port

    Engine Emissions (Marine Engines)
    Applies to: The standards apply most directly to engine manufacturers. However, vessel owners and operators are required to keep emission controls operating as specified, and are responsible for ensuring that engines continue to meet standards if remanufactured.
    Requires: Emissions of soot particles and nitrogen oxides from newly manufactured engines must fall within established limits. The limits depend on engine type, size, and model year.
