Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Marginal note:Standards

• 20 (1) For the 2014 model year and subsequent model years, every Class 2B and Class 3 heavy-duty vehicle and cab-complete vehicle that is not a vocational vehicle or incomplete vocational vehicle must, for the duration of its useful life, have N₂O and CH₄ emission values that do not exceed 0.05 g/mile.

• Marginal note:Calculation

  (2) The N₂O and CH₄ emission values must be calculated in accordance with section 24.

• Marginal note:Fleet calculation

  (3) A company that manufactures or imports vehicles referred to in subsection (1) whose N₂O emission value or CH₄ emission value exceeds the emission standard set out in that subsection must group those vehicles of a given model year into a fleet and, if applicable, subfleets in accordance with section 18 and must calculate the N₂O or CH₄ emission deficit, as the case may be, for that fleet or each of those subfleets, expressed in megagrams of CO₂, using the formula

  ((A – B) × C × D × E) ÷ (1 000 000)

  where

  A

  is 0.05 g/mile;

  B

  is the N₂O or CH₄ family emission limit for the fleet or subfleet, as the case may be, expressed in g/mile;

  C

  is the number of vehicles in the fleet or subfleet, as the case may be;

  D

  is the vehicle’s useful life, expressed in miles; and

  E

  is the global warming potential and is equal to the following number of CO₂ emission credits, expressed in megagrams of CO₂, needed to offset a deficit of N₂O or CH₄:

  • (a) for each megagram of N₂O, 298, and

  • (b) for each megagram of CH₄,

    • (i) for the 2020 model year and earlier model years, 25, and

    • (ii) for the 2021 model year and subsequent model years, 34.

• Marginal note:Separate calculation

  (3.1) For the purposes of subsection (3), if both the N₂O emission value and the CH₄ emission value exceed 0.05 g/mile, the N₂O and CH₄ emission deficits must be calculated separately.

• Marginal note:Family emission limit

  (4) For the purposes of subsection (3), every vehicle within a fleet or subfleet must conform to the N₂O or CH₄ family emission limit for the fleet or subfleet, as the case may be.

• Marginal note:Offsetting deficit

  (5) The deficit calculated under subsection (3) must be offset by using the CO₂ emission credits obtained in accordance with sections 34 to 47 for the averaging set in which the fleet is included.

• Marginal note:No credits

  (6) For greater certainty, the company must not obtain CO₂ emission credits with respect to N₂O and CH₄ emissions for the purpose of participation in the CO₂ emission credit system set out in sections 34 to 47.
