EXHAUST EMISSIONS LEGISLATION 2007-2014 (US EPA & EU)

Emissions shown on the table are the United States Government and European Union emissions standards.  These standards are always evolving and can change based on location. For example California has stricter standards in some areas and air quality boards in California are known to push for the strictest interpretations. Generally if no company manufacturers equipment that meets the current standards your air quality regulators may allow the last version of equipment available. Check with you local air quality jurisdiction to see what is required in your area.
