Greenhouse Gas Emissions
Model year 2013 and later vehicles must meet requirements as specified by EPA10, GHG14, GHG17 and GHG21 regulations. See Table and Table ;for additional information on what EPA and GHG regulations apply to different eCascadia model years.

GHG21 |
GHG14/17 components plus additional components including, but not limited to, transmissions, axles, predictive technologies, idle reduction technologies for vocational vehicles, and tire pressure monitoring systems. |

Model year 2013 and later vehicles are equipped with components that increase energy efficiency such as low-rolling resistance tires, vehicle speed limiters, and aerodynamic devices such as the hood, cab side extenders, and chassis side fairings.
It is a violation of U.S. federal law to alter components that would bring the vehicle out of compliance with certification requirements [Ref: 42 U.S.C. S7522(a) (3)]. It is the owner's responsibility to maintain the vehicle so that it conforms to all EPA regulations.
