Non-road spark ignition engines and equipment (NRSIEE) can contribute significantly to air pollution in Australia, particularly in urban areas. The Australian Government is working towards introducing emission standards to reduce air pollution from NRSIEE which include mowers, chainsaws, generators and outboards.

Reducing NRSIEE emissions – a national approach

NRSIEE refers to a wide range of petrol and gas1-powered equipment such as marine engines and garden equipment. NRSIEE generally do not have the same advanced emission controls found in on-road engines, so they are high polluters relative to their engine size and usage. For example, a two-stroke leaf blower used for one hour can produce as much hydrocarbons as 150 cars over the same time. High-emitting NRSIEE are banned in overseas markets like the USA, Canada, Europe and China.

In December 2015, Australia’s Environment Ministers established a National Clean Air Agreement to ensure a clean air future for Australia.

A key initial action under the Agreement is to introduce new Commonwealth legislation to set emission standards for NRSIEE. This would bring Australia into line with best practice international standards, to ensure we have the same high quality, low-emitting NRSIEE products as those accepted overseas.
