The kangaroo industry says the idea for more native animals to be harvested to help respond to climate change is a vote of confidence in the sector.

Professor Ross Garnaut's final report on climate change has suggested that reducing sheep and cattle numbers and replacing them with 175 million farmed kangaroos would help to dramatically reduce emissions.

John Kelly from the Kangaroo Industry Association says it is a sound concept.

"The idea of getting sheep out of the rangelands and running kangaroos as an alternate enterprise is one that has been around for a long time and it has a great deal of support," he said.

"The simple principle I guess is that it probably makes a great deal of environmental wisdom for us in this country to produce our food from the animals that belong here," he said.

But Mr Kelly says more work is needed to encourage Australians to eat kangaroo.

"What the industry is saying is that before we can go down this path we really do have to look at growing markets for the product it would generate," he said.

"If governments across the country see what [Ross] Garnaut's about as a potential to reduce Australia's carbon footprint, then perhaps we should be looking at throwing a little bit more money at kangaroo industry market development."
