Passenger Automobile and Light Truck Greenhouse Gas Emission Regulations — 20
CO 2 equivalent emission credits 20 (1) For the purposes of subparagraph 162(1)(b)(i) of the Act, a company obtains CO 2 equivalent emission credits if the fleet average CO 2 equivalent emission value in respect of a fleet of passenger automobiles or a fleet of light trucks of a specific model year is lower than the fleet average CO 2 equivalent emission standard for that fleet and model year and the company reports the credits in its end of model year report. Deficits (2) A company incurs deficits if the fleet average CO 2 equivalent emission value in respect of a fleet of passenger automobiles or a fleet of light trucks of a specific model year is higher than the fleet average CO 2 equivalent emission standard for that fleet and model year. Calculation (3) Subject to subsections (3.1) to (3.4), a company must calculate, using the following formula, the credits or deficits for each of its fleets: ECD = (A – B) × C × D 1,000,000 where ECD is the number of credits, if the result is positive, or the number of deficits, if the result is negative, expressed in megagrams of CO 2 equivalent; A is the fleet average CO 2 equivalent emission standard calculated in accordance with section 16 or 17 , as the case may be, expressed in grams per mile; B is the fleet average CO 2 equivalent emission value calculated in accordance with section 18 , expressed in grams per mile; C is the total number of passenger automobiles or light trucks in the fleet; and D is the assumed total mileage of the vehicles in question, namely, (a) 195,264 miles for a fleet of passenger automobiles, or (b) 225,865 miles for a fleet of light trucks. Alternative standard — nitrous oxide (3.1) For each test group in respect of which a company uses, for any given model year, an alternative standard for nitrous oxide (N 2 O) under subsection 10(1) or 12(1), the company must use the following formula, expressing the result in megagrams of CO 2 equivalent, and add the sum of the results for each test group to the number of credits or deficits calculated in accordance with subsection (3) for the fleet to which the test group belongs: 298 × A × (B – C) × D 1,000,000 where A is the total number of passenger automobiles or light trucks in the test group; B is the exhaust emission standard for nitrous oxide (N 2 O) set out in section 1818(f)(1) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR, for the applicable model year, expressed in grams per mile; C is the alternative exhaust emission standard for nitrous oxide (N 2 O) under subsection 10(1) or 12(1) to which the company certifies the test group, expressed in grams per mile; and D is the assumed total mileage of the vehicles in question, namely, (a) 195,264 miles for a fleet of passenger automobiles, or (b) 225,865 miles for a fleet of light trucks. Alternative standard — methane (3.2) For each test group in respect of which a company uses, for any given model year, an alternative standard for methane (CH 4 ) under subsection 10(1) or 12(1), the company must use the following formula, expressing the result in megagrams of CO 2 equivalent, and add the sum of the results for each test group to the number of credits or deficits calculated in accordance with subsection (3) for the fleet to which the test group belongs: 25 × A × (B – C) × D 1,000,000 where A is the total number of passenger automobiles or light trucks in the test group; B is the exhaust emission standard for methane (CH 4 ) set out in section 1818(f)(1) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR, for the applicable model year, expressed in grams per mile; C is the alternative exhaust emission standard for methane (CH 4 ) under subsection 10(1) or 12(1) to which the company certifies the test group, expressed in grams per mile; and D is the assumed total mileage of the vehicles in question, namely, (a) 195,264 miles for a fleet of passenger automobiles, or (b) 225,865 miles for a fleet of light trucks.
