Sustainabile Aviation Fuels have gained considerable momentum in the aviation industry in recent times, due to their potential as a drop-in replacement for conventional fossil aviation fuels. Interest is also supported by the lack of sustainable alternatives with hydrogen or electric powered aircraft deemed unfeasbile and not financially viable in the short term. The European Union have underlined their focus on Sustainable Aviation Fuel (SAF) through the Green Deal and underpinned this with clear numbers and mandates in the ReFuelEU Aviation draft regulations. What, though, exactly does the draft regulation mean and what impact could it have on the SAF market in the coming years? Find out more here.
The European Green Deal defined sustainable aviation kerosene as a key factor in reduced emission aviation. After all, compared with other comprehensive measures such as climate-friendly take-offs and landings, route changes or lighter aircraft, Sustainable Aviation Fuel (SAF) achieves the greatest reduction in CO2 emissions in the aviation industry (IATA – Fly Net Zero).
In the upgraded initiative Fit for 55, the requirement to reduce emissions by 55% by 2030 (compared to 1990 levels) is set. The ReFuelEU Aviation forms a part of the Fit for 55 legislation and within this targets are specified for the aviation industry. Sustainable Aviation Fuel is promoted and its share in conventional fuels increased.
The draft regulation supports the defossilisation measures taken in aviation in other initiatives, such as the Renewable Energies Directive or the EU Emissions Trading Scheme.

With the planned ReFuelEU Aviation Regulation, producers of Sustainable Aviation Fuel (SAF) see a strengthening and clear direction for a regulated higher demand. The concrete quota regulation to be achieved illustrates this. It includes all European airports and their departing aircraft.
The requirement defines the following shares of sustainable aviation fuel:
Total shares in the fuel mix
| 2025 | 2030 | 2035 | 2040 | 2045 | 2050 | |
| % of SAF used in air transport: | 2 % | 6 % | 20 % | 34 % | 42 % | 70 % |
| Of which: synthetic fuels (or e-fuels): | - | 1.2 % | 5 % | 15 % | 20 % | 35 % |
(Source: European Council)
To comply with SAF mandate fuels must (in general) be produced from feedstocks listed in Annex IX, Part A or Part B.
What does it actually mean?… SAF? ... biofuels? ... synthetic fuels or e-fuels? |
Since air transport will continue to rely on drop-in fuels in the long term, it must be ensured that the fuel manufacturing produces correspondingly low greenhouse gas (GHG) emissions. This can be addressed with both synthetic electric fuel and biofuels.
The upcoming ReFuelEU Aviation Regulation will significantly strengthen the SAF market. Manufacturers such as Haltermann Carless, who intends to be the first commercial producer in Germany, continue to invest in new technologies and plants and see their sustainable approach confirmed. Clear target formulations are therefore not only a mandate for SAF manufacturers, but above all a clear perspective for sustainable air travel and more climate protection in the aviation industry.
