Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Marginal note:General

• 24 (1) The N₂O, CH₄ and CO₂ emission values for Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles and the vehicles referred to in subsection (2) — must be determined in accordance with subsection (3) or (4), as the case may be, and

  • (a) using

    • (i) the test procedures, fuels and calculation methods set out for the FTP-based city test and the HFET-based highway test, and

    • (ii) the adjusted loaded vehicle weight and the deterioration factors determined using the durability procedures and method prescribed in section 1823(m) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR; and

  • (b) taking into account

    • (i) sections 1819(d)(4) and (5) and 1819(k)(6) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR, and

    • (ii) the altitude testing conditions set out in sections 1819(a)(5) and 1865(h)(3) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR.

• Marginal note:Electric vehicles and fuel cell vehicles

  (2) In the case of Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles — that are electric vehicles or fuel cell vehicles, the N₂O, CH₄ and CO₂ emission values are considered to be 0 grams per mile.

• Marginal note:Multi-fuel, dual fuel or flexible fuel

  (3) In the case of Class 2B or Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles — that are designed to operate on two or more different fuel types, either separately or simultaneously, the N₂O, CH₄ and CO₂ emission values for a given vehicle or vehicle configuration, as the case may be, must be determined using

  • (a) in the case of N₂O and CH₄ emissions, the highest of the following averages:

    • (i) the arithmetic average of the FTP-based city test and HFET-based highway test emission values, determined in accordance with this section, for that vehicle configuration, weighted 0.55 and 0.45 respectively, tested on gasoline or diesel fuel, and

    • (ii) the arithmetic average of the FTP-based city test and HFET-based highway test emission values, determined in accordance with this section, for that vehicle configuration, weighted 0.55 and 0.45 respectively, tested on the alternative fuel; and

  • (b) in the case of CO₂ emissions, the formula

    (F × A) + ((1 – F) × B)

    where

    F

    is 0.00 unless the company provides the Minister with evidence demonstrating that an alternative value determined for F is more representative for that vehicle configuration,

    A

    is the arithmetic average of the FTP-based city test and HFET-based highway test emission values, determined in accordance with this section, for that vehicle configuration, weighted 0.55 and 0.45 respectively, tested on the alternative fuel, and

    B

    is the arithmetic average of the FTP-based city test and HFET-based highway test emission values, determined in accordance with this section, for that vehicle configuration, weighted 0.55 and 0.45 respectively, tested on gasoline or diesel fuel.

• Marginal note:Other cases

  (4) In the case of other Class 2B and Class 3 heavy-duty vehicles and cab-complete vehicles — excluding those that are vocational vehicles or incomplete vocational vehicles — the N₂O, CH₄ and CO₂ emission values must be determined as follows:

  • (a) in the case of N₂O and CH₄ emissions, by calculating the arithmetic average of the FTP-based city test and HFET-based highway test emission values, weighted 0.55 and 0.45 respectively; and

  • (b) in the case of CO₂ emissions,

    • (i) by making the calculation set out in paragraph (a), or

    • (ii) by calculating the CO₂ emission rate in accordance with section 1819(g) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR.
