The reduction of sulphur content in diesel fuel has radically reduced emissions and improved air quality. In 2002, the Federal Government committed to introducing cleaner transport fuels to Australia.
One of the key elements of this commitment is the reduction of the amount of sulphur in diesel fuel. Sulphur adds to exhaust emissions so lowering sulphur content is a relatively quick and easy way to improve air quality.
In 2009 the Australian limit of sulphur content in diesel was 10 ppm, a massive drop from 5000ppm in the early 2000’s.
Low-sulphur diesel is available in Australia and can be used in any engine that currently runs on regular diesel.
