Charting Australia's Maritime Emissions Reductions
Shipping is vital to Australia's economy and well-being—transporting over 99% of our international trade volume. In 2021–22, the domestic maritime sector emitted around 2 million tonnes of greenhouse gas emissions, or 2.2% of Australia's transport emissions and 0.4% of total national emissions.
As part of the development of a National Transport and Infrastructure Net Zero Roadmap and Action Plan, the Australian Government is working closely with the maritime industry to develop a Maritime Emissions Reduction National Action Plan (MERNAP) in 2023–24.
The MERNAP will set the strategic direction and recommend actions to decarbonise our maritime transport sector, as well as contribute towards reducing international shipping emissions. The plan will seek to identify opportunities and future-proof the domestic maritime industry, ensuring Australia benefits from the global net zero maritime transition.
How can I have my say?
The Government is publishing a series of issues papers for information and consultation on a range of maritime decarbonisation topics to inform the MERNAP's development. Published papers are shown in the table below. Please regularly check this page for the latest papers and further updates. Please send all feedback to MERNAP@infrastructure.gov.au.
