The California Air Resources Board (CARB) issues Executive Orders (EOs) for new off-road compression-ignition engines sold in California. These EOs certify that the engines meet stringent emission standards for the designated model year (MY). This article provides a summary of the EOs issued for My2000 off-road compression-ignition engines, as of September 13, 2023. Engine families and their corresponding certification levels are detailed for various manufacturers.
MY2000 Executive Order Summary for Off-Road Engines
The information below lists the manufacturers granted EOs for their off-road compression-ignition engines during MY2000. Each EO includes the engine family, fuel system, fuel type, tier, and certified emission levels for hydrocarbons (HC), nitrogen oxides (NOx), non-methane hydrocarbons plus nitrogen oxides (NMHC+NOx), carbon monoxide (CO), and particulate matter (PM). These EOs are a critical part of CARB’s efforts to regulate air quality and reduce emissions from off-road equipment.
