Calculation 35 (1) A company must calculate the credits or deficits for each of its fleets or subfleets, as the case may be, using the equation set out in one of the following paragraphs, whichever applies: (a) for Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles, excluding those that are vocational vehicles or incomplete vocational vehicles, 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 , A is the fleet average CO 2 emission standard calculated in accordance with section 22 , expressed in grams of CO 2 per mile, B is the fleet average CO 2 emission value calculated in accordance with section 23 , expressed in grams of CO 2 per mile, C is the number of vehicles in the fleet, and D is the useful life of the vehicles of the fleet, expressed in miles; (b) for vocational vehicles and incomplete vocational vehicles and subject to subsection 38 (2) and clause 41 (1)(b)(ii)(A), ECD = (A – B) × C × D × E 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 , A is the CO 2 emission standard under subsection 26(1), (1.1) or (1.2) that applies to the vehicles of the fleet or subfleet, as the case may be, expressed in grams of CO 2 per short ton-mile, B is the CO 2 family emission limit for the fleet or subfleet, as the case may be, expressed in grams of CO 2 per short ton-mile, C is the payload for the class of vehicles, which is (i) 2.85 short tons for light heavy-duty vehicles, (ii) 5.6 short tons for medium heavy-duty vehicles, and (iii) 7.5 short tons for heavy heavy-duty vehicles, D is the number of vehicles in the fleet or subfleet, as the case may be, and E is the useful life of the vehicles of the fleet or subfleet, as the case may be, expressed in miles; (c) for tractors and incomplete tractors and subject to subsection 38 (2) and clause 41 (1)(b)(ii)(B), ECD = (A – B) × C × D × E 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 , A is the CO 2 emission standard under subsection 27(1), (1.1) or (1.2) that applies to the tractors and incomplete tractors of the fleet or subfleet, as the case may be, expressed in grams of CO 2 per short ton-mile, B is the CO 2 family emission limit for the fleet or subfleet, as the case may be, expressed in grams of CO 2 per short ton-mile, C is the payload for the tractors and incomplete tractors, which is (i) 12.5 short tons for Class 7 tractors and incomplete tractors, (ii) 19 short tons for Class 8 tractors and incomplete tractors of the 2020 model year or an earlier model year and for Class 8 tractors and incomplete tractors of the 2021 model year or a subsequent model year that have a GCWR of less than 54 431 kg (120,000 pounds), and (iii) 43 short tons for Class 8 tractors and incomplete tractors of the 2021 model year or a subsequent model year that have a GCWR of 54 431 kg (120,000 pounds) or more, D is the number of tractors and incomplete tractors in the fleet or subfleet, as the case may be, and E is the useful life of the tractors or incomplete tractors of the fleet or subfleet, as the case may be, expressed in miles; and (d) for heavy-duty engines and subject to subparagraph 41 (1)(c)(iii), ECD = (A – B) × C × D × E 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 , A is the CO 2 emission standard that applies to the fleet of heavy-duty engines under section 30 or subsection 31(2) or (5), as the case may be, expressed in grams per brake horsepower-hour, B is the CO 2 family certification level for the fleet, subject to subsection (3), expressed in grams of CO 2 per brake horsepower-hour, C is the transient cycle conver
