An emissions controlled product (ECP) is a product that has been prescribed in Rules made under the Product Emissions Standards Act 2017 (the Act). The Act provides a framework for regulating emissions from products. Under the Act, it is an offence to import or supply ECPs in Australia if they have not been certified as meeting a standard or are not marked in accordance with the relevant standard.


The first Rules made under the Act, the Product Emissions Standards Rules 2017 (the Rules), prescribe two categories of ECPs; propulsion marine engines and non-road engines.

Propulsion marine engines are new, complete, spark-ignition engines that are, or are likely to be, installed in or on a marine vessel and are used for the propulsion of the vessel. This category includes outboard, inboard and sterndrive engines, and engines installed in personal watercraft.


Non-road engines are new, complete, spark-ignition engines that have a maximum engine power of 19 kW and are not propulsion marine engines. Non-road engines, or the equipment they are installed in, are either portable, self-propelled, or designed to be propelled. This includes most engines installed in outdoor powered equipment such as whipper snippers, chainsaws and lawnmowers, and may also include small pumps and electric generators.


The definitions of propulsion marine engines and non-road engines do not include engines used to propel motor vehicles or aircraft, engines used solely for competition, or scale-model engines. This means that products such as engines used in cars (not including go-karts), motorcycles, and most engines in small, remote-controlled vehicles are not ECPs.

The definitions only apply to new engines so second han\d (used) products are not included.
