Passenger Automobile and Light Truck Greenhouse Gas Emission Regulations — 18.1
Fleet average carbon-related exhaust emission value for the 2011 model year 18.1 (1) The fleet average carbon-related exhaust emission value for the 2011 model year, expressed in grams of CO 2 equivalent per mile, is calculated by dividing 8,887 by the company’s fleet average fuel economy for that model year calculated in accordance with the following formula: Σ (A × B) C where A is the fuel economy level for each model type, expressed in miles per gallon, determined in accordance with the following provisions, taking into account subsection 19(2): (a) in the case of advanced technology vehicles, the provisions of section 208 of Title 40, chapter I, part 600, subpart C, of the CFR, for the model year in question, or (b) in all other cases, the provisions of section 510(c)(2) of Title 40, chapter I, part 600, subpart F, of the CFR, for the model year in question; B is the number of vehicles of the model type in question in the fleet; and C is the total number of vehicles in the fleet. Fleet average carbon-related exhaust emission value for 2012 model year and subsequent model years (2) Subject to subsections (8) and (10), a company must calculate the fleet average carbon-related exhaust emission value for each of its fleets of the 2012 model year and subsequent model years using the following formula: Σ (A × B) C where A is the following carbon-related exhaust emission value for each model type and includes, if an election is made under subsection 10(2), the exhaust emission for nitrous oxide (N 2 O) and methane (CH 4 ): (a) in the case of electric vehicles and fuel cell vehicles, 0 grams of CO 2 equivalent per mile, (b) in the case of plug-in hybrid electric vehicles, the value determined in accordance with section 113(n)(2) of Title 40, chapter I, part 600, subpart B, of the CFR for the model year in question, taking into account subsection 19(2) and the following clarifications, and expressed in grams of CO 2 equivalent per mile: (i) the value in respect of exhaust emissions is determined in accordance with section 510(j)(2) of Title 40, chapter I, part 600, subpart F, of the CFR, and (ii) the equivalent value in respect of the electricity grid for the electricity that is used to recharge the energy storage system is equal to 0 grams of CO 2 equivalent per mile, or (c) in all other cases, the value determined in accordance with section 510(j)(2) of Title 40, chapter I, part 600, subpart F, of the CFR, for the model year in question, taking into account subsection 19(2), and expressed in grams of CO 2 equivalent per mile; B is the number of vehicles of the model type in question in the fleet; and C is the total number of vehicles in the fleet. Advanced technology (3) When calculating the fleet average carbon-related exhaust emission value in accordance with subsections (1) and (2) for fleets of the 2011 to 2016 model years, a company may, for the purposes of the descriptions of B and C in subsections (1) and (2), elect to multiply the number of advanced technology vehicles in its fleet by 1.2, if the company reports that election and indicates the number of credits obtained as a result of that election in its end of model year report. Multiplier for certain vehicles (4) Subject to subsection (5), when calculating the fleet average carbon-related exhaust emission value in accordance with subsection (2) for fleets of the 2017 to 2024 model years, a company may, for the purposes of the descriptions of B and C in subsection (2), elect to multiply the number of advanced technology vehicles, natural gas vehicles or natural gas dual fuel vehicles in its fleet by the number set out in the following table in respect of that type of vehicle for the model year in question, if the company reports that election and indicates the number of credits obtained as a result of that election and the number of vehicles in question in its end of model year report.
