Four major European air carriers—Air France-KLM, easyJet, Ryanair and Deutsche Post DHL Group—have joined forces with non-governmental organizations such as Transport & Environment in a “Fueling Flight Initiative” meant to help advance a key draft EU law.

The legislative proposal from the European Commission would spur aviation’s take-up of renewable energy, which so far has developed much more slowly in this industry than in others including automotive and power.

The Commission’s ReFuelEU Aviation proposal would ensure that the share of sustainable aviation fuels (SAF) used in the bloc grows from almost nothing currently to at least 2% in 2025, 5% in 2030 and—after subsequent five-year steps—63% in 2050. These SAF targets are known as blending mandates. They would cover advanced biofuels, which exclude traditional types that risk competing with food production.

Within the proposed SAF targets, the draft law would also guarantee minimum amounts for synthetic aviation fuels, a type of renewable energy of non-biological origin with especially high emission-savings potential compared to fossil aviation fuel (i.e., kerosene).

While commending the European Commission for its exclusion of food and feed crop-based biofuels, the Fueling Flight Initiative urges the EU’s legislators to strengthen the proposal by adding:

• Earlier and more ambitious sub-targets for e-kerosene, including an earlier start, if sufficient green hydrogen and renewable electricity becomes available.

• Financial support to enable new biofuel feedstocks, under strict sustainability criteria.

• The creation of a European SAF industrial alliance with a focus on research and development.

• A comprehensive SAF registry applying to fuel suppliers.

The proposal on SAF is being scrutinized by EU national governments and the European Parliament in a process due to last well into 2022. The proposal is part of a package of draft climate legislation meant to reduce EU greenhouse gas emissions by at least 55% in 2030 versus 1990 levels and to make the bloc climate-neutral by mid-century.

The Fueling Flight Initiative was convened by the European Climate Foundation and ClimateWorks. Technical advice was provided by the International Council on Clean Transportation.
