 Each manufacturer shall demonstrate compliance with these values in accordance with Section E.2.5.2. 

2.5.1.1 For each model year, a manufacturer must demonstrate compliance 

with the fleet average requirements in this section E.2.5.1 based on one of two 

options applicable throughout the model year , either: 

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 section 1961.1, title 13, CCR, 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 section 1961.1, title 13, CCR, 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). 

2.5.1.1.1 For the 2009 and 2010 model years, a manufacturer that 

selects compliance Option 2 must notify the Executive Officer of that selection in 

writing within 30 days of the effective date of the amendments to this section 

2.5.1.1. or must comply with Option 1.

2.5.1.1.2 For the 2011 and later model years, a manufacturer that 

selects compliance Option 2 must notify the Executive Officer of that selection in 

writing prior to the start of the applicable model year or must comply with Option 1.

2.5.1.1.3 When a manufacturer is demonstrating compliance using 

Option 2 for a given model year, the term “in California” as used in subsections 

E.2.5.2.3 and E.3.2 means 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).

2.5.1.1.4 A manufacturer that selects compliance Option 2 must 

provide to the Executive Officer production, delivery, and sales values separately 

for the District of Columbia and for each individual state within the average.

2.5.2 Calculation of Fleet Average Greenhouse Gas Value. 

2.5.2.1 Basic Calculation. 

2.5.2.1.1 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 AB 

965 vehicles and vehicles certified in accordance with Section E.1.12 of these test 

procedures, using the following formula. 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), as modified in Part II of these test procedures. 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 N2O + 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 Program emissions data to

demonstrate compliance with the greenhouse requirements may substitute the term 1.9 

CO2-equivalent grams per mile for the terms “296 x N2O + 23 x CH4” in this equation.

* * * * 

2.5.2.1.2 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. 

* * * * 

(d) A manufacturer that elects to use CAFE Program emissions data to 

demonstrate compliance with the greenhouse requirements shall calculate the A/C 

Direct Emissions Allowance for each Vehicle Configuration by calculating the 

A/C Direct Emissions Allowance for each air conditioning system used in that 

Vehicle Configuration and calculating a sales-weighted average for that Vehicle

Configuration.

2.5.2.1.3 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 CO2-equivalent grams per mile emissions reductions. 

 

* * * * 

(d) A manufacturer that elects to use CAFE Program emissions data to 

demonstrate compliance with the greenhouse requirements shall calculate the A/C 

Indirect Emissions Allowance for each Vehicle Configuration by calculating the 

A/C Indirect Emissions Allowance for each air conditioning system used in that 

Vehicle Configuration and calculating a sales-weighted average for that Vehicle 

Configuration.

* * * * 

3.2 Calculation of Greenhouse Gas Credits/Debits. 

* * * * 

3.2.3 Procedure for Offsetting Greenhouse Gas Debits. 

3.2.3.1. 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. A manufacturer demonstrating 

compliance under Option 2 in section E.2.5.1.1, must calculate the emission debits that 

are subject to a civil penalty under Health and Safety Code section 43211 separately for 

California, the District of Columbia, and for each individual state that is included in the 

fleet average greenhouse gas requirements in subsection E.2.5.1.1. The manufacturer 

must calculate these emission debits separately for California, the District of Columbia,

and each individual state using the formula in subsections E. 3.2.1.2 and E.3.2.2, 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, and 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 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 occurred.

following sentences to the first paragraph: Beginning with 2010 model-year vehicles or engines, 

at the time of certification manufacturers shall state, based on good engineering judgment and 

available information, that the emission control devices on their vehicles or engines are durable 

and are designed and will be manufactured to operate properly and in compliance with all 

applicable requirements for the full useful life (or allowable maintenance interval) of the vehicles 

or engines. Also, vehicles and engines tested for certification shall be, in all material respects, 

substantially the same as production vehicles and engines. If it is determined pursuant to title 13 

CCR, Division 3, Chapter 2, Article 5, sections 2166 through 2174 that any emission control 

component or device experiences a systemic failure because valid failures for that component or 

device meet or exceed four percent or 50 vehicles (whichever is greater) in a California-certified 

engine family or test group, it constitutes a violation of the foregoing test procedures and the 

Executive Officer of the Air Resources Board may require that the vehicles or engines be recalled 

or subjected to corrective action as set forth in title 13 CCR, Division 3, Chapter 2, Article 5, 

sections 2166 through 2174. Certification applications may not be denied based on the foregoing 

information provided that the manufacturer commits to correct the violation.

least three emission data and/or engineering development vehicles from MDV test 

groups. 

2.23.2 The same test group shall not be selected in the succeeding two 

years unless the manufacturer produces fewer than three test groups. If the manufacturer 

produces more than three TLEV, LEV, ULEV or SULEV test groups per model year, the 

Executive Officer may request 50oF testing of specific test groups. If the manufacturer 

provides a list of the TLEV, LEV, ULEV and SULEV test groups that it will certify for a 

model year and provides a description of the technologies used on each test group 

(including the information in Section G.2.3.1.2(1)), the Executive Officer shall select the 

test groups subject to 50oF testing within a 30 day period after receiving such a list and 

description. The Executive Officer may revise the test groups selected after the 30 day 

period if the information provided by the manufacturer does not accurately reflect the test 

groups actually certified by the manufacturer. 

2.34 Greenhouse Gas Vehicle Test Group. 

2.34.1 Within each test group, a manufacturer shall group vehicles into 

Greenhouse Gas Vehicle Test Groups based on the following criteria being identical. 

(a) Vehicle make and model; 

(b) Transmission class and driveline (e.g., 2-wheel-drive, 4-wheeldrive); 

(c) Aspiration method (e.g., naturally aspirated, turbocharged); 

(d) Camshaft configuration; 

(e) Valvetrain configuration; and 

(f) Inertia weight class. 

2.34.2 Greenhouse Gas Emission Test Vehicle Selection. Within each test group, 

the vehicle configuration shall be selected from the greenhouse gas vehicle test group that 

is expected to be “worst-case” for greenhouse gas emissions, as calculated in Section 

E.2.5.2.1, subject to approval by the Executive Officer. A manufacturer may select 

additional vehicle configurations from greenhouse gas vehicle test groups with lower 

greenhouse emissions values than the “worst-case” configuration.

3.2 50oF Requirements. 

A manufacturer shall demonstrate compliance with the 50o

F requirement each year by 

testing at least three PC or LDT and three MDV emission data and/or engineering development 

vehicles (with at least 4000 miles) as determined under the provisions of Section G.2.23 of these 

test procedures. Only TLEVs, LEVs, ULEVs and SULEVs are to be considered for testing at 

50o

F. It is not necessary to apply deterioration factors (DFs) to the 50oF test results to comply 

with this requirement. 

* * * * 

3.4 Greenhouse Gas Testing Requirements. 

A manufacturer shall demonstrate compliance with the greenhouse requirements each 

year by testing one vehicle per each test group that represents the vehicle configuration that is 

expected to be “worst-case” for greenhouse gas emissions, as calculated in Section E.2.5.2.1, 

subject to approval by the Executive Officer. A manufacturer may test additional vehicles within 

the test group that represent vehicle configuration with lower greenhouse gas emissions values 

than the “worst-case” configuration. All vehicles shall be tested using both the FTP and 

Highway Test Procedures as modified in Part II of these test procedures. A manufacturer may 

use emissions data from tests it conducts as part of the Corporate Average Fuel Economy 

Program (CAFE), in accordance with 40 CFR Part 600 – Fuel Economy of Motor Vehicles, to 

demonstrate compliance with the greenhouse requirements, once those data have been judged 

acceptable by the U.S. Environmental Protection Agency. A manufacturer that elects to use 

CAFE Program emissions data to demonstrate compliance with the greenhouse requirements

must use all of the data that is used by the U.S. Environmental Protection Agency to determine a 

manufacturer’s corporate average fuel economy for the applicable model year, and may forego 

testing of the “worst-case” configuration.
