When the federal MY 2017-2025 GHG regulation became finalized, in August 2012, CARB adopted regulatory provisions to the effect that vehicles meeting federal GHG emission standards for MY 2017-2025 are “deemed to comply” with California standards. The GHG emission regulation was aligned with the federal 2017-2025 GHG emissions and fuel economy proposal by the EPA/NHTSA. The regulations were part of the part of the “Advanced Clean Car Rules” that also included the LEV III emission standards for criteria air pollutants and ZEV regulations. In January 2012, CARB approved GHG emission regulations for MY 2017-2025 light-duty vehicles. Additional adjustment factors and special methods were used for calculation in vehicles fueled by alternative fuels and in ZEV vehicles. In the calculation of average emission for a manufacturer, the city values were taken with a weight factor of 55%, and the highway values with a weight of 45%. Two sets of CO 2 values were determined: (1) city values measured over the FTP test, and (2) highway values over the HWFET cycle. The AC emission allowances were determined based on the design of the air conditioning system, with higher allowances for more leak-free and energy-efficient systems. Manufacturers were allowed to use N 2O = 0.006 g/mi in lieu of measuring N 2O exhaust emissions. The GHG standards were defined in grams per mile of CO 2-equivalent emissions (g CO 2/mi in Table 1), calculated from the following formula:ĬO 2-Equivalent = CO 2 + 296 × N 2O + 23 × CH 4 - AC Allowances
I believe the smog cert station can tell from the sequential serial number using their database, so if CA origin, you won't escape the CA reqs even if the sticker is missing. The under-hood emissions sticker will tell you, if it's there. In addition, medium-duty passenger vehicles (MDPVs) from 8,500 to 10,000 lbs GVW were included in the LDT2 category for GHG emission standards. AFAIK you cannot determine CA vs 49 states from the VIN. There were two fleet average GHG requirements: (1) for passenger car/light-duty truck 1 (PC/LDT1) category, including passenger cars and light-duty trucks below 3,750 lbs equivalent test weight (ETW) and (2) for light-duty truck 2 (LDT2) category, including light trucks between 3,751 lbs ETW and 8,500 lbs gross vehicle weight (GVW). The GHG standards were incorporated into the California low emission vehicle (LEV) legislation.
