A Western Australian seafood company has been certified as the first carbon neutral seafood business in the world.

Austral Fisheries catch toothfish and icefish in Australia's sub-Antarctic waters and prawns in northern Australian waters.

Following an independent audit, the company purchased carbon credits in the form of 190,000 native trees to offset the estimated 27,422 tonnes of carbon dioxide emissions it will produce this year.

For the project 190,000 native trees, certified under the Australian Government Carbon Neutral program, have been planted in the Wheatbelt by sequestration group Carbon Neutral.

Austral chief executive David Carter said the certification, along with a Marine Stewardship certification for the groups fisheries, were part of a commitment to sustainability.

"We identified a need to reduce and offset our carbon emissions to help ensure the health of our oceans, which is fundamental to our business," he said.

"As primary industries we are the ones that will be feeling the impact of climate change before really any other parts of the economy and it just seems a bit Churlish not to be doing our part."
