The Australian government has released the final rules for its noxious emissions standards for marine engines. The new standards, which will be enforced from July 1, 2018, include outboards, personal watercraft and sterndrive engines. Only engines that meet the emissions standards or have an exemption will be allowed into Australia. They do not include earlier marine engines.

A government website that marine engines that are certified as meeting emissions standards of the US Environmental Protection Agency (EPA), California Air Resources Board (CARB), the rules of Canada and the European Union automatically meet the Australian standard. The page said that any engines not meeting these standards importers can apply for Australian certification. The government said it would grant a list of exemptions.

A cost recovery levy of 0.45% will be charged on all imported engines.

Local manufacture includes the manufacture of engines and does not include the assembly of imported engines into equipment.

“The US Standard is widely considered to be international best practice,” said a statement from the Australian government. “The US Standard has led the world in reducing emissions from propulsion marine engines and non-road engines, and other jurisdictions are moving to align their standards with the US Standard. Canada and California follow the US Standard model.

"The latest EU standards (recognized in section 26 under which foreign certification is allowed) are harmonised with the current US Standard for exhaust emissions. Thus, aligning the Australian emissions standards for propulsion marine engines and non-road engines with the US exhaust emissions standards will maximize the environmental and health benefits for the Australian community while minimizing compliance costs for businesses.”
