Senator Boxer (D-CA) and Representative Solis (D-CA) introduced the Marine Vessel Emissions Reduction Act of 2007 in companion versions (S. 1499 and H.R. 2548 respectively) to amend the Clean Air Act to reduce air pollution from
marine vessels. The bills, if enacted into law, would wholly ignore MARPOL Annex VI and impose unilateral standards for sulfur levels in marine fuels and require advanced marine vessel emission controls on new and in-use marine engines.
