SAFs are low-carbon alternatives to fossil jet fuels, produced from renewable sources like waste oils, biomass, and captured CO₂. They can reduce lifecycle emissions by up to 80% and are compatible with existing aircraft and fueling infrastructure, making them one of the most immediate and scalable solutions for decarbonizing aviation.

Fully electric aircraft eliminate direct CO₂ emissions by using battery-powered propulsion instead of traditional jet engines. While current battery technology limits range and capacity, continued advancements are making electric aviation increasingly viable for regional travel and private flights, offering a promising step toward zero-emission flight.

Advances in aircraft design and materials play a crucial role in reducing fuel consumption and emissions. Next-generation wing designs, ultra-light composite materials, and drag-reducing innovations improve efficiency, allowing aircraft to use less fuel per flight and move aviation toward a more sustainable future.

Hydrogen aircraft use either hydrogen fuel cells to generate electricity or burn liquid hydrogen in modified turbine engines, producing only water vapor as a byproduct. If sourced from renewable energy, hydrogen-powered flight has the potential to be entirely emissions-free, though challenges remain in fuel production, storage, and distribution.

Beyond aviation-specific solutions, the Future of Flying Fund also supports innovations in sustainability, energy efficiency, and infrastructure that contribute to a net-zero future. By investing in emerging technologies, we help drive lasting change across the entire aviation ecosystem.
