Non-road diesel exhaust emissions at NSW coal mines are a significant source of fine particle pollution in the NSW Greater Metropolitan and Hunter regions. The EPA conducted a cost-benefit analysis of emission reduction options, such as using fuels and engines that produce fewer emissions, at 64 open-cut and underground mines.

In partnership with the EPA, the construction sector has developed and implemented various approaches to reduce diesel emissions from plant and equipment, which improve air quality for people living and working near construction sites.

A component of the EPA’s Diesel and Marine Emissions Management Strategy is to reduce diesel emissions from locomotives in NSW. Since 2013, the EPA has conducted studies and workshops to share best practice measures to reduce air pollution using the latest technology.

The EPA is working with the shipping industry to reduce air pollution from ports and ships.

The Commonwealth Government is responsible for regulating fuel used by cruise ships in Sydney Harbour. Specifications for fuel used by cruise ships in Sydney Harbour are no longer regulated under NSW legislation.

Many programs support the EPA’s commitment to reduce pollution from non-road diesel engines, using the latest science and technology.

Discover how the EPA measures and regulates emissions from industry - through legislation, air emissions standards and licensing. Read our studies and policies about these emissions, and learn about the obligations of industries.

The Approved Methods for the Modelling and Assessment of Air Pollutants in NSW (2022) lists the statutory methods to be used for modelling and assessing emissions of air pollutants in NSW.

NSW industries and commercial premises can ensure they comply with NSW air quality regulations by sampling and analysing their emissions of air pollutants.
