Aviation Decarbonization Research: SAF, Drones, and Door-to-Door Emissions | University of Sydney

University of Sydney researchers are working with airlines and airports on ways to cut aviation emissions, including sustainable aviation fuel, drone logistics, and door-to-door emissions analysis. The group estimates aviation accounts for 4-6% of global CO2 today, and could reach around 10% if demand doubles while other transport sectors electrify. The research focuses on practical industry partnerships with Qantas, Air New Zealand, Sydney Airport, and others. One stream looks at blending biomass-derived SAF with conventional jet fuel to reduce price volatility and reliance on hydrogen or electrification. Another expands emissions accounting beyond airport-to-airport to include the full travel journey. For anyone tracking aviation decarbonisation, the useful takeaway is the emphasis on local SAF production and the need for a global policy perspective. The article does not include cost data or emissions reductions from specific projects, so it reads as an overview of the research program rather than a results report.
