Heavy-duty Vehicle and Engine Greenhouse Gas Emission Regulations

Marginal note:Standard

• 30 (1) Subject to subsection (2), paragraph 25(d) and sections 31 and 33, every heavy-duty engine of a given model year must, for the duration of its useful life, have a CO₂ emission value that does not exceed the following CO₂ emission standard:

  • (a) in the case of a spark-ignition engine of the 2016 to 2020 model years, 627 g/BHP-hr;

  • (b) in the case of a spark-ignition engine of the 2021 model year or a subsequent model year other than a heavy heavy-duty engine, 627 g/BHP-hr;

  • (c) in the case of a compression-ignition engine of the 2014 to 2020 model years that is of a type referred to in column 1 of the table to this paragraph, the standard set out in column 2 or 3 for the model year in question; or

  • (d) in the case of a compression-ignition engine of the 2021 model year or a subsequent model year or a heavy heavy-duty engine that is a spark-ignition engine of the 2021 model year or a subsequent model year that is of a type referred to in column 1 of the table to this paragraph, the standard set out in column 2, 3 or 4 for the model year in question.

• Marginal note:Election — spark-ignition engines

  (2) A company may elect to have any of its spark-ignition engines referred to in paragraph (1)(a) or (b) conform to the emission standard set out in paragraph (1)(c) or (d) that is applicable to compression-ignition engines of the same model year, as if they were compression-ignition engines, instead of the standard set out in paragraph (1)(a) or (b).
