 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 separate values for the number of vehicles

producedtion, and deliveredy, and for sales values separately for in the District of 

Columbia and for each individual state within the average.

4.5 Greenhouse Gas Reporting Requirements.

(a) For the purpose of demonstrating compliance with greenhouse gas 

requirements, the manufacturer shall provide by May 1 of the calendar year following the 

close of the model year:

(i) a comprehensive list of all emission test results, including the test 

vehicle description and identification number, CO2, CH4, and N2O emission data, 

the data and/or justifications used to determine the “worst case” greenhouse gas 

test vehicle configuration, as required by G.2.3.2, for each greenhouse gas vehicle 

test group. A manufacturer shall not submit any emission test results from 

vehicles tested, or calculated results, as part of the Corporate Average Fuel 

Economy Program, unless those results have been judged acceptable by the U.S. 

Environmental Protection Agency, in accordance with §600.007-08. A 

manufacturer that submits data from the Corporate Average Fuel Economy 

Program must clearly indicate whether the data is derived from vehicle testing or 

whether it is calculated. 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;

(ii) a description of each air conditioning system and all data used to 

calculate the A/C Direct Emissions Allowance in subsection E.2.5.2.1.2 and the 

A/C Indirect Emissions Allowance in subsection E.2.5.2.1.3;

(iii) for vehicles certifying using the optional alternative compliance 

mechanisms in subsection E.2.5.2.2.1, all data required therein;

 (iv) for manufacturers demonstrating compliance under section 

E.2.5.1.1, Option 1, final California vehicle sales delivery volumes for each 

greenhouse gas vehicle test group; and

(v) for manufacturers demonstrating compliance under section 

E.2.5.1.1, Option 2, final combined and individual state sales delivery volumes for 

each greenhouse gas vehicle test group for 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).
