In April 2018 what is now the Department of Climate Change, Energy, the Environment and Water (DCCEEW) commenced an evaluation for a national approach to manage emissions from non-road diesel engines.
The Issue
- Australia currently has no regulations to control noxious emissions from non-road diesel engines.
- Total particulate emissions from non-road diesel engines are significantly larger than total particulate emissions from all on-road motor vehicles in Australia (petrol, diesel and LPG), even though the number of non-road diesel engines is only about 3% of the number of on-road engines.
- They emit particulate matter (mainly fine particles, PM2.5), oxides of nitrogen, volatile organic compounds and a range of air toxics which are harmful to human health.
- Current international best practice standards emission standards for diesel engines are US Tier 4f
