1 Each manufacturer shall demonstrate compliance with these values in accordance with section 1961.l(a)(1)(B).
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).
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 N 2 0 + 23 x CH4" in this equation.
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);
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.
(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.

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."
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.

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.
