Cummins has long been a pioneer in emissions research and development. We have invested in critical technologies to achieve current and future emissions standards and to meet the needs of our customers. The emissions solutions we use today are the direct result of a technology plan that was put in place in the early 1990s. It is a plan that will carry us through 2017 and beyond.

The following designations will appear in the Emissions column of each engine rating offered to identify the emissions level of the engine and the regulation that the engine will be certified to or compliant with once placed on the market:

N/A - Rating is not compliant with or not applicable to current regulations

IMO1 - IMO Tier I compliant; Engine International Air Pollution Prevention (EIAPP) certificates available from American Bureau of Shipping (ABS) or U.S. EPA

IMO2 - IMO Tier II compliant; per regulation, Engine International Air Pollution Prevention (EIAPP) certificates will not be issued until July 2010

EPA2 - EPA Tier 2 compliant

EC - Nonroad Mobile Machinery Directive, Stage IIIa certified

Certain ratings may not be available for sale in some areas due to emissions compliance. Other local certifications may be available. For more information on current emissions regulations in your area, contact your local Cummins professional.
