A Qantas Boeing 787 flight from the US to Australia yesterday was the first ever flight to be powered by mustard seed-based biofuel.

Qantas International CEO Alison Webster says the biofuel blend is expected to decrease emissions along the flight path by 7 per cent, paving the way to sustainable aviation.

Qantas says their goal is to be running regular flights powered by biofuel by 2020, creating a new industry for Australian farmers.
