On 11 June 2011, The Minister for Infrastructure and Transport announced new pollution standards for light vehicles. In Australia, vehicle emissions standards are set via the Australian Design Rules, which are legislative instruments under the Motor Vehicle Standards Act 1989. Proposed standards are based on a review of European “Euro 5” and “Euro 6” emission standards for light vehicles. They are designed to cut a new car's maximum allowable emissions of hydrocarbons, oxides of nitrogen and particulate matter. The Regulation Impact Statement was prepared by the Department of Infrastructure and Transport and assessed as adequate by the Office of Best Practice Regulation.
