Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Version of section 29 from 2013-02-22 to 2018-11-15:


Marginal note:Standards

  •  (1) Every heavy-duty engine that is a compression-ignition engine of the 2014 and subsequent model years and heavy-duty engine that is a spark-ignition engine of the 2016 and subsequent model years must have N2O and CH4 emission values that do not exceed an emission standard of 0.10 g/BHP-hr for N2O and 0.10 g/BHP-hr for CH4 for the applicable useful life of the engine.

  • Marginal note:Values

    (2) The N2O and CH4 emission values for the engines referred to in subsection (1) correspond to the emission values of the tested engine configuration referred to in section 235(a) of Title 40, chapter I, subchapter U, part 1036, subpart C, of the CFR, for the engine family, measured in accordance with the transient duty cycle, taking into account sections 108(d) to (f) and 150(g) of subpart B, sections 235(b) and 241(c) and (d) of subpart C and subparts E and F of part 1036, Title 40, chapter I, subchapter U, of the CFR.

  • Marginal note:Engine configuration

    (3) For the purposes of subsection (2), the tested engine configuration for the model year in question is determined using the engine sales in Canada if none of the engines of the engine family are sold in the United States.

  • Marginal note:Fleet calculation

    (4) A company that manufactures or imports engines referred to in subsection (1) that exceed any of the standards set out in that subsection must group those engines of a given model year into fleets in accordance with section 18 and must calculate the N2O and CH4 emission deficits for each fleet, expressed in megagrams of CO2 and rounded in accordance with subsection 35(2), using the formula

    ((A – B) × C × D × E × F) ÷ (1 000 000)

    where

    A
    is 0.10 g/BHP-hr for N2O and 0.10 g/BHP-hr for CH4;
    B
    is the N2O or CH4 family emission limit for the fleet and corresponds to the N2O or CH4 deteriorated emission level value, calculated using the applicable emission value determined in accordance with subsection (2);
    C
    is the number of engines in the fleet;
    D
    is the transient cycle conversion factor calculated in accordance with the applicable variable “CF” in section 705(b) of Title 40, chapter I, subchapter U, part 1036, subpart H, of the CFR;
    E
    is the useful life for the engine, as follows:
    • (a) 110,000 miles for a spark-ignition engine; and

    • (b) the following number of miles for a compression-ignition engine:

      • (i) 110,000 miles for a light heavy-duty engine,

      • (ii) 185,000 miles for a medium heavy-duty engine, and

      • (iii) 435,000 miles for a heavy heavy-duty engine; and

    F
    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

    (5) For the purposes of subsection (4), every heavy-duty engine within a fleet must conform to the N2O or CH4 family emission limit determined by the company for the fleet that corresponds to the deteriorated emission level value determined for B in subsection (4).

  • Marginal note:Offsetting fleet emission deficit

    (6) The deficit calculated under subsection (4) 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

    (7) For greater certainty, and subject to subsection (8), 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.

  • Marginal note:Credits for low N2O emissions

    (8) If a company’s heavy-duty engines from a fleet of the 2014, 2015 or 2016 model year conform to an N2O family emission limit that is less than 0.04 g/BHP-hr, the company may obtain CO2 emission credits for the purpose of participation in the CO2 emission credit system set out in sections 34 to 47, using the following formula for each fleet, expressed in megagrams of CO2 and rounded in accordance with subsection 35(2):

    ((A – B) × C × D × E × F) ÷ (1 000 000)

    where

    A
    is 0.04 g/BHP-hr for N2O;
    B
    is the N2O family emission limit for the fleet and corresponds to the N2O deteriorated emission level value, calculated using the applicable emission value determined in accordance with subsection (2);
    C
    is the number of engines in the fleet;
    D
    is the transient cycle conversion factor calculated in accordance with the applicable variable “CF” in section 705(b) of Title 40, chapter I, subchapter U, part 1036, subpart H, of the CFR;
    E
    is the useful life for the engine, as follows:
    • (a) 110,000 miles for a spark-ignition engine; and

    • (b) the following number of miles for a compression-ignition engine:

      • (i) 110,000 miles for a light heavy-duty engine,

      • (ii) 185,000 miles for a medium heavy-duty engine, and

      • (iii) 435,000 miles for a heavy heavy-duty engine; and

    F
    is the global warming potential and is equal to 298 Mg of CO2.
