About the guide

The Product Emissions Standards Act 2017 (PES Act) sets emissions standards for certain products that are imported or supplied in Australia.

The product emissions standards set limits on emissions from new products that are:

  • non-road spark-ignition engines with maximum engine power at or below 19 kilowatts
  • non-road spark-ignition engines used to propel marine vessels.

Domestic manufacture does not include the assembly of imported engines into products.

This guide provides information to support anyone considering making an application to us for Australian certification. In certain circumstances, products may be eligible for exemptions from the standards under Part 5 of Product Emissions Standards Rules 2017. Refer to the separate guide on exemptions under the Act.
