The report, published by the Future Farm Industries Cooperative Centre (CRC), concludes that jet fuel made from the Mallee tree, from the Great Southern region of Western Australia, would be sustainable and suitable enough to use for commercial flights. Virgin Australia regional airlines group executive, Merren McArthur, says: "Virgin Australia remains committed to research into the feasibility of aviation biofuels and reducing greenhouse gas emissions in Australia. The results show Mallee jet fuel is a more sustainable option than our current fossil-based fuel supply." The study showed that if all flights departing Perth Airport were powered by Mallee derived fuel, emissions could fall by at least 40 per cent and supply could be viable by 2021.
