SUSTAINABLE AVIATION FUEL
Future Flight|March 2023
Aviation has a very high impact on the planet, accounting for over two percent of global CO2 emissions, and nearly double that warming impact through non-CO2 effects. For this industry to persist in a zero-carbon world, we must find ways to reduce its impacts through new technology, operational efficiency, sustainable aviation fuels (SAF) and carbon offsets.
SUSTAINABLE AVIATION FUEL

Sustainable aviation fuels (SAF) are low-carbon fuel alternatives for the aviation industry. These non-petroleum-based aviation fuels are generally produced from bio-based feedstocks such as energy crops, waste, residues and end-of-life products (in which case they may be synonymous with aviation biofuels or bio-jet-fuels), or fossil waste such as industrial off-gases like carbon monoxide (CO). E-fuels (directly capturing CO2 from the air for fuel manufacture) are gaining traction but are very energy inefficient and will not be ready for market for several decades.

What is the issue?

Aviation has by far the greatest impact per kilometre travelled of all transport options. With the sector projected to continue its fast growth, how do we reduce emissions from air travel? While some emissions can be reduced by improving operational and technical efficiency, the immense energy requirements of flying mean that airplanes will be reliant on energy-dense liquid fuels for a long time to come.

What are we doing?

WWF has undertaken comprehensive research on the potential of producing sustainable aviation fuels (SAF) within sub-Saharan Africa. Based on this work, WWF continues to engage policy makers and industry leaders to layout a roadmap for SAF production in South Africa, ensuring that this growing market has firm sustainability principles embedded from the outset.

How do we do this?

Sustainability and connectivity: top of the agenda for private jet industry

The executive aviation industry is currently facing a paradox. On the one hand, demand for private flying remains strong, propelled by the rise in the number of high-net-worth individuals around the globe. While on the other hand, the industry is increasingly being questioned by the public, the media, and politicians over its environmental credentials.

Long-awaited Starliner launch breaks a six-decade drought

An Atlas rocket has launched with astronauts aboard for the first time since Gordon Cooper's final Mercury flight in his Faith 7 capsule on 15 May 1963, powered by an Atlas LV-3B 130-D. The Atlas V rocket that launched on 5 June, manufactured by United Launch Alliance and powered at liftoff by a Russian-built RD-180 first-stage engine, carried Boeing's Starliner crew ferry ship to orbit following multiple launch delays over the past several days.
