Business Aviation’s Green Future And Sustainable Aviation Fuels

Sustainable aviation fuel, or SAF, is one of the most promising and exciting solutions to reducing carbon emissions from flights. As the aviation industry moves to decarbonize all aspects of air travel, SAFs are one of the tools the sector is utilizing to help meet its climate action goals. Private business aviation is poised to become more environmentally friendly through the increased adoption of SAFs, and the private jet sector has the potential to drive enthusiasm for SAFs across the entire aviation industry. But what are SAFs? Here’s everything you need to know about sustainable aviation fuels, including:

WHAT ARE SUSTAINABLE AVIATION FUELS?

Sustainable Aviation Fuels, or SAFs, are a cleaner, greener alternative to the fossil fuel used by most jets. SAFs allow the aviation industry to reduce its carbon footprint, because they come from sustainable, renewable sources.

HOW MUCH CAN SAFS SAVE IN CARBON EMISSIONS?

    • SAFs can be up to 80% less carbon-intensive over their life cycle than fossil jet fuels, according to the Air Transportation Action Group. In fact, the International Air Transportation Association says the CO2 absorbed by crops used to make SAFs is roughly equal to the amount produced during jet flights, which would make SAFs roughly carbon neutral; but, carbon emissions from the rest of the process—transportation, processing, refining, and distribution—must be taken into account.

WHAT ARE SUSTAINABLE AVIATION FUELS MADE FROM?

    • SAFs are made from a variety of processes using sustainable feedstocks (raw materials used to make fuels). Those include municipal solid waste, like product packaging, food scraps, and newspapers; excess agricultural, forestry, or wood waste; used cooking oil; and energy crops, like fast-growing grasses and algae. There are even emerging methods to produce SAFs without using biological material, instead utilizing renewable electricity or the sun’s energy to break up water and carbon dioxide molecules—but according to Aviation Benefits Beyond Borders, the non-biological alternative is currently “prohibitively expensive and needs further development.”

ARE SUSTAINABLE AVIATION FUELS SAFE?

      • Yes. In order to be approved for use, SAFs have to go through strict testing—first in a laboratory, then on the ground, and finally, in the air during actual flight—to be certified for safe use by the American Society for Testing and Materials. Currently, SAF is blended up to 50% with fossil jet fuels to ensure it is safely compatible with existing jet fueling systems. That’s because some of the less environmentally friendly chemicals in fossil jet fuel are included on purpose to prevent fuel leaks in older engines. Since this isn’t a problem with newer engines, Aviation Benefits Beyond Borders says the blend limits will eventually increase as older technology is phased out, until they reach 100% SAF.

CAN SAFS BE USED IN ANY AIRCRAFT?

    • Yes. SAFs are a “drop-in fuel,” meaning they can be used, stored, and distributed in the same manner and using the same existing infrastructure as fossil jet fuel. This is because SAFs are nearly chemically identical to fossil jet fuel, and can be blended with it.

HOW DO SAFS FIGURE INTO CURRENT CLIMATE ACTION GOALS?

WHO IS CURRENTLY USING SAFS?

    • More and more commercial airlines, like LufthansaJetBlue, and United Airlines, are making commitments to use SAFs, and some airlines, like Lufthansa, even offer passengers the ability to “buy” SAFs when they book their flights paying for the appropriate amount of the sustainable fuel to offset their trip’s CO2 emissions. In 2016, Norway’s Oslo Airport became the first airport in the world to offer airlines the ability to refuel with SAFs, using Finnish provider Neste’s 50-50 blend of fossil jet fuel and SAF. Aviation Benefits Beyond Borders tracks data on SAF use; to date, over 320,000 commercial flights have used SAFs since 2011, and six airports can currently boast a regular supply of SAFs. 

What Role Does Private Business Aviation Have To Play?

Companies that prioritize sustainability and own or use private jets have the chance to set an example for the rest of the aviation industry, with National Business Aviation Association VP of Communications Dan Hubbard calling them important drivers of sustainability changes. For example, NBAA CEO Ed Bolan notes that winglets, vertical extensions of an aircraft’s wings that help improve fuel efficiency and cruising range, were introduced first in private jets before becoming an airline staple. Even though private flights account for a smaller amount of fossil jet fuel consumption, Commercial Aviation Alternative Fuels Initiative Executive Director Steve Csonka said the business aviation community’s enthusiasm for SAFs will help drive the sustainable fuel’s production to increase. With that potential in mind, the Business Aviation Coalition for Sustainable Aviation Fuel has even released a guide detailing how leaders in the business aviation community can incorporate SAFs.

WHAT ARE THE OTHER BENEFITS OF USING SAFS?

    • In addition to CO2 emission reduction, the use of SAFs can reduce sulfur oxide and nitrogen oxide emissions. According to SkyNRG, SAFs also have a higher energy density than fossil jet fuel, and have an improved fuel efficiency of 1.5-3%, meaning jets using SAFs have more range or higher payload capabilities. And, since the feedstocks used to make SAFs can be grown in more places than fossil fuels can be drilled, SAFs could reduce the cost of fuel for aviation providers—and help them gain market security by having a more diverse supply of fuel sources.

WHAT ARE THE BARRIERS TO WIDER SAF USE?

    • Limited availability of SAFs remains the biggest obstacle. NBAA CEO Ed Bolen laid out the next steps for wider SAF adoption in business aviation at a panel discussion in December 2020, saying, “Now that we know sustainable aviation fuel works … How do we make it more available, and how do we increase adoption?” The global supply chain network for sustainable aviation fuels is still growing—but as technological innovations continue in the industry, they are expected to become more and more economically viable. Aviation Benefits Beyond Borders says remaining challenges to wider SAF implementation include locking down a supply of sustainable feedstock for making the fuels, ensuring that SAFs are priced competitively with existing fossil jet fuels, and compelling governments to make policy changes to incentivize the SAF industry to grow in scale.
