SYDNEY, AAP – Qantas boss Alan Joyce has reaffirmed the airline will be carbon neutral by 2050 and outlined three means by which to do it.

The airline has created the role of chief sustainability officer and incumbent Andrew Parker is reporting to the chief executive.

Mr Joyce said efforts to produce sustainable aviation fuel was key to reducing emissions.

“We’re working with the sustainable aviation fuel industry here in Australia and we’re hopeful we can get to a stage where it gets us to the bulk of our target,” he told Flight Centre’s Illuminate conference on Thursday.

Ampol is a major provider of jet fuel in Australia.

The airline will also encourage more customers to choose to offset their carbon emissions. About 10 per cent of customers do this.

Plane technology was the third means of reducing carbon emissions.

Qantas is working with aircraft manufacturers on replacing its domestic fleet.

Mr Joyce said sustainability was one selection criteria being used to evaluate new aircraft.
