Sources with knowledge of the upcoming proposal indicate that there will be an overall mandate covering sustainable aviation fuels (SAFs), with a starting point of 2% in 2025, moving to 5% in 2030, 20% in 2035, 32% in 2040, and 63% in 2050.
Penalties in case of non-compliance are also being considered, the same sources indicate.
In addition, a sub-mandate for e-fuels – such as hydrogen produced from electrolysis – is also under discussion, potentially starting at 0.7% in 2030 and increasing to 25% by 2050.
Sustainable aviation fuels, created from advanced biofuels and renewable electro-fuels, can be blended with kerosene without changes to aircraft engines, making it an attractive means of decarbonisation for the airline industry as low-carbon jet technology such as e-planes and hydrogen-power come to maturity.
The European Commission is hoping that the legislation will increase the supply of SAFs and lower prices, making it commercially viable for airlines already struggling with the pandemic-driven downturn.
“The production cost of SAF is currently at least twice as high as that of conventional jet fuel,” the European Commission says in a document outlining its intentions. “A key objective of the initiative is therefore to support the commercial development and rollout of innovative SAF at an early stage, to ensure their large-scale availability at low costs,” it adds.
To achieve this, the Commission cites a “SAF blending mandate” at the top of the list of policy options available, saying it would “provide investors with the necessary confidence to invest in the production of sustainable aviation fuels and for airlines to pursue an efficient fuels policy”.
To prevent discrepancies emerging between EU member states, ReFuelEU is expected to take the form of a regulation, which will be immediately applicable across all EU countries, without the need for national implementing rules.
As to what constitutes a SAF, it is understood that e-fuels made from green electricity will qualify, but questions remain as to what kind of biofuels will be acceptable.
A particular question mark hovers over the status of crop-based biofuels. Environmental campaigners have called for them to be excluded from the SAF designation.
“Sustainable fuels must actually work for the environment too, which is why we need targets for synthetic fuels, stricter criteria for second-generation biofuels, and no crop-based fuels,” said William Todts, executive director at green NGO Transport and Environment (T&E).
Emmanuel Desplechin, secretary general of ePURE, a European renewable ethanol association, defended the use of crop-based biofuels for aviation. In comments made in January, he touted ethanol’s lower emissions compared to fossil fuels, warning that “the EU should not throw out the baby with the bath water by restricting all crop-based biofuels”.
Gloria Gaupmann, chair of the Advanced Biofuels Coalition – an industry group representing producers of second generation biofuels – believes that a “dedicated legal instrument” setting binding mandates for SAF is “the right way forward”.
“A precondition for the availability of sufficient SAF volumes is a reliable policy framework that creates a stable investment climate,” Gaupmann added.
