Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Marginal note:Standards

• 20 (1) Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles of the 2014 and subsequent model years — excluding those referred to in the definition vocational vehicle in subsection 1(1) — must have N₂O and CH₄ emission values that do not exceed 0.05 g/mile for N₂O or 0.05 g/mile for CH₄ for the applicable useful life of the vehicle.

• 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) that exceed any of the standards set out in that subsection must group those vehicles of a given model year into a fleet and subfleets in accordance with section 18 and must calculate the N₂O and CH₄ emission deficits for that fleet, expressed in megagrams of CO₂ and rounded in accordance with subsection 35(2), by adding the deficits for all those subfleets, if applicable, using the formula

  ((A – B) × C × D × E) ÷ (1 000 000)

  where

  A

  is 0.05 g/mile for N₂O and 0.05 g/mile for CH₄;

  B

  is the N₂O or CH₄ family emission limit for the fleet or subfleet, as the case may be, and corresponds to the N₂O or CH₄ emission value calculated in accordance with section 24;

  C

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

  D

  is the useful life for the vehicle, namely, 120,000 miles; and

  E

  is the global warming potential and is equal to the following number of credits needed to offset a N₂O and CH₄ deficit:

  • (a) an emission credit of 298 Mg of CO₂ to offset a deficit of 1 Mg of N₂O; and

  • (b) an emission credit of 25 Mg of CO₂ to offset a deficit of 1 Mg of CH₄.

• Marginal note:Family emission limit

  (4) For the purposes of subsection (3), every vehicle within the fleet or subfleet, as the case may be, must conform to the N₂O or CH₄ family emission limit corresponding to the emission value determined for B in the formula set out in that subsection.

• 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.
