Cal. Code Regs. tit. 13, § 1961.1
(a) Greenhouse Gas Emission Requirements. The greenhouse gas emission levels from new 2009 through 2016 model year passenger cars, light-duty trucks, and medium-duty passenger vehicles shall not exceed the following requirements. 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 greenhouse gas emission requirements, however, passenger cars, light-duty trucks 0-3750 lbs. LVW, and medium-duty passenger vehicles are not eligible for this exemption.
(1) Fleet Average Greenhouse Gas Requirements for Passenger Cars, Light-Duty Trucks, and Medium-Duty Passenger Vehicles.
1. For each model year, a manufacturer must demonstrate compliance with the fleet average requirements in this section 1961.1(a)(1)(A) based on one of two options applicable throughout the model year, either:
d. A manufacturer that selects compliance Option 2 must provide to the Executive Officer separate values for the number of vehicles produced and delivered for sale in the District of Columbia and for each individual state within the average.
(A)(ii) For the 2012 through 2016 model years, a manufacturer may elect to demonstrate compliance with this section 1961.1 by demonstrating compliance with the 2012 through 2016 MY National greenhouse gas program as follows:
Option 1: the total number of passenger cars, light-duty trucks, and medium-duty passenger vehicles that are certified to the California exhaust emission standards in this section 1961.1, and are produced and delivered for sale in California; or
Option 2: the total number of passenger cars, light-duty trucks, and medium-duty passenger vehicles that are certified to the California exhaust emission standards in this section 1961.1, and are produced and delivered for sale in California, the District of Columbia, and all states that have adopted California's greenhouse gas emission standards for that model year pursuant to Section 177 of the federal Clean Air Act (42 U.S.C. § 7507).
(B) Calculation of Fleet Average Greenhouse Gas Value.
1. Basic Calculation.
a. Option A: Each manufacturer shall calculate both a “city” grams per mile average CO2-equivalent value for each GHG vehicle test group and a “highway” grams per mile average CO2-equivalent value for each GHG vehicle test group, including vehicles certified in accordance with section 1960.5 and vehicles certified in accordance with section 1961(a)(14), using the following formula. Option B: For a manufacturer that elects to demonstrate compliance with the greenhouse gas requirements using CAFE data, “GHG vehicle test group” shall mean “subconfiguration” in this subsection 1961.1(a)(1)(B)1.a. Greenhouse Gas emissions used for the “city” CO2-equivalent value calculation shall be measured using the “FTP” test cycle (40 CFR, Part 86, Subpart B). Greenhouse Gas emissions used for the “highway” CO2-equivalent value calculation shall be based on emissions measured using the Highway Test Procedures.
CO2-Equivalent Value = CO2 + 296 x N20 + 23 x CH4 - A/C Direct Emissions Allowance - A/C Indirect Emissions Allowance
A manufacturer may use N2O = 0.006 grams per mile in lieu of measuring N2O exhaust emissions. A manufacturer that elects to use CAFE data to demonstrate compliance with the greenhouse requirements may substitute the term 1.9 CO2-equivalent grams per mile for the terms “296 x N20 + 23 x CH4” in this equation.
b. A/C Direct Emissions Allowance. A manufacturer may use the following A/C Direct Emission Allowances, upon approval of the Executive Officer, if that manufacturer demonstrates that the following requirements are met. Such demonstration shall include specifications of the components used and an engineering evaluation that verifies the estimated lifetime emissions from the components and the system. A manufacturer shall also provide confirmation that the number of fittings and joints has been minimized and components have been optimized to minimize leakage. No A/C Direct Emissions Allowance is permitted if the following requirements are not met.
(A)(i) The fleet average greenhouse gas exhaust mass emission values from passenger cars, light-duty trucks, and medium-duty passenger vehicles that are produced and delivered for sale in California each model year by a large volume manufacturer shall not exceed:
FLEET AVERAGE GREENHOUSE GAS EXHAUST MASS EMISSION REQUIREMENTS FOR PASSENGER CAR, LIGHT-DUTY TRUCK, AND MEDIUM-DUTY PASSENGER VEHICLE WEIGHT CLASSES1

1 Each manufacturer shall demonstrate compliance with these values in accordance with section 1961.l(a)(1)(B).
C. Only multiple-lip compressor shaft seals shall be used (with either compressor body o-rings or gaskets).
C. An A/C Direct Emissions Allowance greater than 3.0 CO2- equivalent grams per mile may apply for an air conditioning system that reduces refrigerant leakage further than would be obtained from a “low-leak air conditioning system.” A maximum A/C Direct Emissions Allowance of 6.0 CO2-equivalent grams per mile may be earned for an air conditioning system that has 100 percent containment of refrigerant during “normal operation.” To obtain an A/C Direct Emissions Allowance greater than 3.0 CO2-equivalent grams per mile, the manufacturer must provide an engineering evaluation that supports the allowance requested.
iii. For an air conditioning system that uses HFC-152a, CO2 refrigerant, or any refrigerant with a GWP of 150 or less: An A/C Direct Emissions Allowance shall be calculated using the following formula:
A/C Direct Emissions Allowance = A - (B x C)
where: A = 9 CO2-equivalent grams per mile (the lifetime vehicle emissions expected from an air conditioning system that uses refrigerant HFC-134a);
B=9 CO2 - equivalent g/mi x
GWP
1300
where: B is the lifetime vehicle emissions expected from an air conditioning system that uses a refrigerant with a GWP of 150 or less, and
“GWP” means the GWP of this refrigerant; and
C = 1, except for an air conditioning system that meets the criteria of a “low-leak air conditioning system.”
For an air conditioning system that meets or exceeds the criteria of a “low-leak air conditioning system,” the following formula shall apply:
C =1 - (0.12 x credit)
where: “credit” equals 3.0 CO2-equivalent grams per mile for a “low-leak air conditioning system” that meets the criteria of section 1961.1(a)(1)(B)1.b.i., or
“credit” equals a value greater than 3.0 CO2-equivalent grams per mile for an air conditioning system that reduces refrigerant leakage further than would be obtained from a “low-leak air conditioning system.” A maximum credit of 6.0 CO2-equivalent grams per mile may be earned for an air conditioning system that has 100 percent containment of refrigerant during normal operation. To obtain a credit greater than 3.0 CO2-equivalent grams per mile, the manufacturer must provide an engineering evaluation that supports the credit requested.
c. A/C Indirect Emissions Allowance. A manufacturer may use the following A/C Indirect Emissions Allowances, upon approval of the Executive Officer, if the manufacturer demonstrates using data or an engineering evaluation that the air conditioning system meets the following requirements. A manufacturer may use the following A/C Indirect Emissions Allowances for other technologies, upon approval of the Executive Officer, if that manufacturer demonstrates that the air conditioning system achieves equal or greater CO2-equivalent grams per mile emissions reductions.
C. Has an externally controlled compressor (such as an externally controlled variable displacement or variable speed compressor or an externally controlled fully cycling fixed displacement compressor) that adjusts evaporative temperature to minimize the necessity of reheating cold air to satisfy occupant comfort.
B. 27.5 CO2-equivalent grams per mile per 100 cc of maximum compressor displacement for a system that uses CO2 as the refrigerant
B. 1.1 CO2-equivalent grams per mile per 100cc of maximum compressor displacement for a system that uses CO2 as the refrigerant.
d. Upstream Greenhouse Gas Emission Adjustment Factors for Alternative Fuel Vehicles. A grams per mile average CO2-equivalent value for each GHG vehicle test group certifying on a fuel other than conventional gasoline, including vehicles certified in accordance with section 1960.5 and vehicles certified in accordance with section 1961(a)(14), shall be calculated as follows:
(CO2 + A/C Indirect Emissions) x (Fuel Adjustment Factor) + 296 x N2O + 23 x CH4 + A/C Direct Emissions
where:
A/C Indirect Emissions = A - B
where: “A” represents the indirect emissions associated with an A/C system that does not incorporate any of the A/C improvements described in section 1961.1(a)(1)(B)1.c. A is determined by the following emission factors, with a maximum value of 17.0 CO2-equivalent grams per mile for a system that has one evaporator and a maximum value of 21.0 CO2-equivalent grams per mile for a system that has two evaporators.
A = 9.6 CO2-equivalent grams per mile per 100cc of maximum compressor displacement for an A/C system that does not use CO2 as the refrigerant or
A = 52.8 CO2-equivalent grams per mile per 100cc of maximum compressor displacement for an A/C system that uses CO2 as the refrigerant.
B = A/C Indirect Emissions Allowance as calculated per section 1961.1(a)(1)(B)1.c.
A/C Direct Emissions = 9 CO2-equivalent grams per mile -- A/C Direct Emissions Allowance as calculated per section 1961. 1(a)(1)(B)1.b.

e. Calculation of CO2-Equivalent Emissions for Hydrogen Internal Combustion Engine Vehicles and for Electric and Hydrogen ZEVs. The grams per mile average CO2-equivalent value for each GHG vehicle test group certifying to ZEV standards, including vehicles certified in accordance with section 1960.5 and vehicles certified in accordance with section 1961(a)(14), shall be:
A/C Direct Emissions + Upstream Emissions Factor
where: A/C Direct Emissions = 9 CO2-equivalent grams per mile -- A/C Direct Emissions Allowance as calculated per section 1961.1(a)(1)(B)1.b.
The Upstream Emissions Factors are:

1 The Executive Officer may approve use of a lower upstream emissions factor if a manufacturer demonstrates the appropriateness of the lower value by providing information that includes, but is not limited to, the percentage of hydrogen fuel or the percentage of electricity produced for sale in California using a “renewable energy resource.”
2. Calculation of Greenhouse Gas Values for Bi-Fuel Vehicles, Fuel-Flexible Vehicles, Dual-Fuel Vehicles, and Grid-connected Hybrid Electric Vehicles. For bi-fuel, fuel-flexible, dual-fuel, and grid-connected hybrid, electric vehicles, a manufacturer shall calculate a grams per mile average CO2-equivalent value for each GHG vehicle test group, in accordance with section 1961.1(a)(1)(B)1., based on exhaust mass emission tests when the vehicle is operating on gasoline.
a. Optional Alternative Compliance Mechanisms. Beginning with the 2010 model year, a manufacturer that demonstrates that a bi-fuel, fuel-flexible, dual-fuel, or grid-connected hybrid electric GHG vehicle test group will be operated in use in California on the alternative fuel shall be eligible to certify those vehicles using this optional alternative compliance procedure, upon approval of the Executive Officer.
ii. For each GHG vehicle test group that receives approval by the Executive Officer under section 1961.1(a)(1)(B)2.a.i., a grams per mile CO2-equivalent value shall be calculated as follows:
CO2-equivalent value = [A x E x B x C] + [(1 - (A x E x B)) x D]
where: A = the percentage of previous model year vehicles within a GHG vehicle test group that were operated in use in California on the alternative fuel during the previous calendar year;
B = the percentage of miles traveled by “A” during the previous calendar year;
C = the CO2-equivalent value for the GHG vehicle test group, as calculated in section 1961.1(a)(1)(B)1, when tested using the alternative fuel;
D = the CO2-equivalent value for the GHG vehicle test group, as calculated in section 1961.1(a)(1)(B)1, when tested using gasoline; and
E = 0.9 for grid-connected hybrid electric vehicles or
E = 1 for bi-fuel, fuel-flexible, and dual-fuel vehicles.
The Executive Officer may approve use of a higher value for “E” for a grid-connected hybrid electric vehicle GHG vehicle test group if a manufacturer demonstrates that the vehicles can reasonably be expected to maintain more than 90 percent of their original battery capacity over a 200,000 mile vehicle lifetime. The manufacturer may demonstrate the appropriateness of a higher value either by providing data from real world vehicle operation; or by showing that these vehicles are equipped with batteries that do not lose energy storage capacity until after 100,000 miles; or by offering 10 year/150,000 mile warranties on the batteries.
3. Calculation of Fleet Average Greenhouse Gas Values.
a. Each manufacturer's PC and LDT1 fleet average Greenhouse Gas value for the total number of PCs and LDT1s produced and delivered for sale in California, including vehicles certified in accordance with section 1960.5 and vehicles certified in accordance with section 1961(a)(14), shall be calculated as follows:
[0.55 x (Σ City Test Group Greenhouse Gas Values) + 0.45 x (Σ Highway Test Group Greenhouse Gas Values)] / Total Number of PCs and LDT1s Produced, Including ZEVs and HEVs
where: City Test Group Greenhouse Gas Value = [(Total Number of Vehicles in a Test Group -- Σ Number of Vehicles in Optional GHG Test Vehicle Configurations) x “worst-case” calculated CO2-equivalent value + Σ (Number of vehicles in Optional GHG Test Vehicle Configurations x applicable calculated CO2-equivalent value)] measured using the FTP test cycle; and
Highway Test Group Greenhouse Gas Value = [(Total Number of Vehicles in a Test Group -- Σ (Number of Vehicles in Optional GHG Test Vehicle Configurations) x “worst-case” calculated CO2-equivalent value + Σ (Number of vehicles in Optional GHG Test Vehicle Configurations x applicable calculated CO2-equivalent value)] measured using the Highway Test Procedures.
b. Each manufacturer's LDT2 and MDPV fleet average Greenhouse Gas value for the total number of LDT2s and MDPVs produced and delivered for sale in California, including vehicles certified in accordance with section 1960.5 and vehicles certified in accordance with section 1961(a)(14), shall be calculated as follows:
[0.55 x (Σ City Test Group Greenhouse Gas Values) + 0.45 x (Σ Highway Test Group Greenhouse Gas Values)] / Total Number of LDT2s and MDPVs Produced, Including ZEVs and HEVs
where: City Test Group Greenhouse Gas Value = [(Total Number of Vehicles in a Test Group -- Σ Number of Vehicles in Optional GHG Test Vehicle Configurations) x “worst-case” calculated CO2-equivalent value + Σ (Number of vehicles in Optional GHG Test Vehicle Configurations x applicable calculated CO2-equivalent value)] measured using the FTP test cycle; and
Highway Test Group Greenhouse Gas Value = [(Total Number of Vehicles in a Test Group - Σ Number of Vehicles in Optional GHG Test Vehicle Configurations) x “worst-case” calculated CO2-equivalent value + Σ (Number of vehicles in Optional GHG Test Vehicle Configurations x applicable calculated CO2-equivalent value)] measured using the Highway Test Procedures.

3. In the 2016 model year, a small volume manufacturer and an independent low volume manufacturer shall either:
(b) Calculation of Greenhouse Gas Credits/Debits.
(1) Calculation of Greenhouse Gas Credits for Passenger Cars, Light-Duty Trucks, and Medium-Duty Passenger Vehicles.
(A) In the 2000 through 2008 model years, a manufacturer that achieves fleet average Greenhouse Gas values lower than the fleet average Greenhouse Gas requirement applicable to the 2012 model year shall receive credits for each model year in units of g/mi determined as:
[(Fleet Average Greenhouse Gas Requirement for the 2012 model year) -- (Manufacturer's Fleet Average Greenhouse Gas Value)] x (Total No. of Vehicles Produced and Delivered for Sale in California, Including ZEVs and HEVs).
(B) In 2009 through 2016 model years, a manufacturer that achieves fleet average Greenhouse Gas values lower than the fleet average Greenhouse Gas requirement for the corresponding model year shall receive credits in units of g/mi Greenhouse Gas determined as:
[(Fleet Average Greenhouse Gas Requirement) -- (Manufacturer's Fleet Average Greenhouse Gas Value)] x (Total No. of Vehicles Produced and Delivered for Sale in California, Including ZEVs and HEVs).
(3) Procedure for Offsetting Greenhouse Gas Debits.
(A) A manufacturer shall equalize Greenhouse Gas emission debits by earning g/mi Greenhouse Gas emission credits in an amount equal to the g/mi Greenhouse Gas debits, or by submitting a commensurate amount of g/mi Greenhouse Gas credits to the Executive Officer that were earned previously or acquired from another manufacturer. A manufacturer shall equalize Greenhouse Gas debits for PCs, LDTs, and MDPVs within five model years after they are earned. If emission debits are not equalized within the specified time period, the manufacturer shall be subject to the Health and Safety Code section 43211 civil penalty applicable to a manufacturer which sells a new motor vehicle that does not meet the applicable emission standards adopted by the state board. The cause of action shall be deemed to accrue when the emission debits are not equalized by the end of the specified time period. For a manufacturer demonstrating compliance under Option 2 in subsection 1961.1(a)(1)(A)1., the emission debits that are subject to a civil penalty under Health and Safety Code section 43211 shall be calculated separately for California, the District of Columbia, and each individual state that is included in the fleet average greenhouse gas requirements in subsection 1961.1(a)(1)(A)1. These emission debits shall be calculated for each individual state using the formula in subsections 1961.1(b)(1)(B) and 1961.1(b)(2), except that the “Total No. of Vehicles Produced and Delivered for Sale in California, including ZEVs and HEVs” shall be calculated separately for the District of Columbia and each individual state.
For the purposes of Health and Safety Code section 43211, the number of passenger cars and LDT1s not meeting the state board's emission standards shall be determined by dividing the total amount of g/mi Greenhouse Gas emission debits for the model year calculated for California by the g/mi Greenhouse Gas fleet average requirement for PCs and LDTs 0-3750 lbs. LVW applicable for the model year in which the debits were first incurred. For the purposes of Health and Safety Code section 43211, the number of LDT2s and MDPVs not meeting the state board's emission standards shall be determined by dividing the total amount of g/mi Greenhouse Gas emission debits for the model year calculated for California by the g/mi Greenhouse Gas fleet average requirement for LDTs 3751 lbs. LVW -- 8500 lbs. GVW and MDPVs applicable for the model year in which the debits were first incurred.
