Australia

Heavy-Duty Diesel Engines

Emissions from diesel engines in Australia are regulated through the issue of Australian Design Rules (ADRs) which are based on equivalent European regulations. Standards for new heavy-duty vehicles cover emissions emanating from three broad vehicle categories, namely heavy-duty passenger vehicles (GVW > 3.5t), medium-light duty (3.5t < GVW ≤ 5t) and heavy-duty (GVW > 5t) buses as well as medium (3.5t < GVW ≤ 12t) and heavy-duty (GVW > 12t) goods vehicles. The latest standards (ADR 80/03) are based on Euro V regulations, and came into force in January 2010 for new vehicle models (January 2011 for all existing models). Manufacturers may also adopt US EPA 07 or Japanese JE 05 standards as acceptable alternatives (with the exception of heavy-duty passenger vehicles, which must be Euro V-compliant).

Medium and Heavy-Duty Vehicle Diesel Emission Standards (g/kWh): ADR 80

* dates applicable for new models. For existing models, standards came into force within 12 months.
** for heavy-duty passenger vehicles (> 3.5t), European standards apply only.

Passenger Cars and Light Duty Vehicles

Standards for new diesel engine light-duty vehicle emissions are applicable for passenger cars, buses and goods vehicles with a GVW below 3.5 tonnes. The current standards, ADR 79/01, came into force in January 2006 for new models (January 2007 for existing models), based on Euro 4 emission regulations. In June 2011 the government published  new diesel emissions legislation for light-duty vehicles, following intense discussions with industry stakeholders.  Under the new regulations all new models must, by 1 November 2013, comply with “core” Euro 5 emission standards. These “core” standards are less-stringent than their regular EU Euro 5 counterparts, and have been devised to facilitate the transition between Euro 4 and Euro 5. Among other things, the “core” standards do not require compliance with Euro 5 PM standards (i.e. vehicles must comply with Euro 4 PM standards), and have lower OBD requirements for PM. Nonetheless, by 1 November 2016 all vehicle models must comply with full Euro 5 standards. In addition, under the new legislation full Euro 6 standards will come into force in 1 July 2017 for new models, and 1 July 2018 for all existing models.

Light-Duty Diesel Engine Emission Standards (g/km): ADR 79

* dates applicable for new models. For existing models, standards came into force 12 months after original implementation date.
** date refers to the introduction of “core” Euro 5 standards as described above for new models. Full Euro 5 standards come into force in 1 November 2016 for all models.

Non-Road Vehicle Engines

The Australian Government currently does not regulate emissions from non-road diesel engines. A report was commissioned to identify measures that would lead to the supply and purchase of cleaner non-road diesel engines in order to bring about a reduction in pollutant emissions from such sources. The report was presented in April 2010, whereby it was recommended that non-road emission standards based on legislation abroad (in particular US EPA standards) should be considered as an option in order to address emissions from this sector.

New Zealand

Heavy-Duty Diesel Engines

Emission standards in New Zealand enable manufacturers to select between a number of alternative regulatory regimes, namely Australian, EU, US EPA and Japanese standards. Plans are currently in place for the introduction of more stringent emission standards for new heavy-duty vehicles in 2011/2012, although no such plans are in place for light duty vehicles.

* for existing models, Japan 05 became an alternative in January 2010.
** for existing models, EPA 2004 is an acceptable alternative.
