Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Introduction.
This section
					 1961.3 sets the greenhouse gas
					 emission levels from new 2017 and subsequent model year passenger cars,
					 light-duty trucks, and medium-duty passenger vehicles. Light-duty trucks from
					 3751 lbs. LVW - 8500 lbs. GVW that are certified to the Option 1 LEV II NOx
					 Standard in section
					 1961(a)(1) are
					 exempt from these green-
house gas emission requirements, however, passenger cars,
					 light-duty trucks 0-3750 lbs. LVW, and medium-duty passenger vehicles are not
					 eligible for this exemption.
Emergency vehicles may be excluded from these greenhouse
					 gas emission requirements. The manufacturer must notify the Executive Officer
					 that they are making such an election, in writing, prior to the start of the
					 applicable model year or must comply with this section
					 1961.3.
(a)
Greenhouse Gas Emission
				  Requirements.
(1)
Fleet
				  Average Carbon Dioxide Requirements for Passenger Cars, Light-Duty Trucks, and
				  Medium-Duty Passenger Vehicles.
For the purpose of determining
				  compliance with this subsection (a)(1), the applicable fleet average
				  CO2 mass emission standards for each model year is the
				  sales-weighted average of the calculated CO2 exhaust
				  mass emission target values for each manufacturer. For each model year, the
				  sales-weighted fleet average CO2 mass emissions value
				  shall not exceed the sales-weighted average of the calculated
				  CO2 exhaust mass emission target values for that
				  manufacturer.
(A)
Fleet Average Carbon
				  Dioxide Target Values for Passenger Cars.
The fleet average
				  CO2 exhaust mass emission target values for passenger
				  cars that are produced and delivered for sale in California each model year
				  shall be determined as follows:
1. For
				  passenger cars with a footprint of less than or equal to 41 square feet, the
				  gram per mile CO2 target value shall be selected for the
				  appropriate model year from the following table:
Model
							 Year
CO2 Target Value
							 (grams/mile)
2017
263.0
2018
250.0
2019

2025 and subsequent
179.0
2.
				  For passenger cars with a footprint of greater than 56 square feet, the gram
				  per mile CO2 target value shall be selected for the
				  appropriate model year from the following table:

3.
				  For passenger cars with a footprint that is greater than 41 square feet and
				  less than or equal to 56 square feet, the gram per mile
				  CO2 target value shall be calculated using the following
				  equation and rounded to the nearest 0.1 grams/mile:
Target gCO2/mile =
					 [
a
x
f
] +
b
Where:
f
is the vehicle footprint and
					 coefficients
a
and
b
are selected from the
					 following table for the applicable model year.
