EU Readies Guidance on Jet Fuel Shortages, Pushes Cleaner Fuels as Hormuz Tensions Escalate

The European Commission will issue guidance to airlines on airport slots, anti-tankering, passenger rights and public service obligations should jet fuel supplies tighten amid the Iran war. Commissioners say there are no shortages currently, but a sustained blockade of the Strait of Hormuz would have catastrophic effects. The EU plans a new fuel observatory, clarifications on anti-tankering rules and a push to ramp up sustainable and synthetic aviation fuels while exploring imports of alternative jet fuel grades.

Key Points

  • The Commission will issue guidance to airlines on airport slots, anti-tankering, passenger rights and public service obligations in case of jet fuel shortages.
  • A new fuel observatory will be created to monitor supplies, beginning with jet fuel, and emergency stock releases must be transparent to avoid market distortions.
  • The EU will accelerate production of sustainable aviation fuel (SAF) and synthetic fuels and is examining imports of alternative grades such as U.S. Jet A - actions that affect aviation, refining and energy markets.

European officials are preparing a set of measures aimed at safeguarding air travel if jet fuel supplies come under pressure because of the war involving Iran. The Commission will give airlines instructions on how to manage airport slots, anti-tankering practices, passenger rights and public service obligations should shortages appear, a senior EU commissioner said.

Commissioner Apostolos Tzitzikostas stressed there were no fuel shortages "as of today" but warned that a continued blockade of the narrow Strait of Hormuz would be "catastrophic" for Europe and the world. He pointed to the strategic importance of the waterway, noting that one-fifth of the world’s oil and liquefied natural gas transited the strait before the U.S.-Israel bombing campaign began on Feb. 28.

The commissioner underscored the EU’s exposure in aviation fuel markets: the bloc imports roughly 30-40% of its jet fuel needs, and about half of those imports come from the Middle East. Those import figures frame the Commission’s push to tighten coordination and to consider alternative supply options.


Planned measures and monitoring

The Commission is due to present a broader package of energy and transport measures on Wednesday. As part of the response, officials will establish a new fuel observatory to monitor supply conditions, starting with jet fuel. The observatory is intended to provide ongoing visibility into flows and inventories so policymakers can respond promptly if disruptions materialize.

"If real supply issues arise, our emergency stocks must be put to best use," the commissioner said, adding that any national release of fuel should be conducted with full transparency to avoid market distortions. He also said there were currently no indications that "widespread cancellations" of flights would occur in the coming weeks or months.


Rules, alternative imports and fuel standards

The Commission will clarify the bloc’s anti-tankering measure, which is designed to prevent aircraft from loading extra fuel in lower-cost locations to save money. The existing legislation already includes exemptions for shortages; the forthcoming guidance will make those exemptions and the application of the rule clearer.

Officials are also studying the option of importing alternative jet fuels such as U.S. jet fuel grade Jet A. That grade has a higher freezing point than the European standard, a technical difference flagged by the Commission as a matter to consider if imports were to increase.


Longer-term shift to cleaner aviation fuels

The Commission will press the bloc to speed up production of sustainable aviation fuel (SAF) and synthetic fuels so the EU can cut its reliance on Middle East imports. The commissioner confirmed details that had been reported earlier this week, saying the step-up in SAF and synthetic fuel production is a central element of the Commission’s strategy.

On immediate social and consumer impacts, the commissioner said there was "no need at this point to intervene in how people live, work or travel," and that Europe was prepared to welcome tourists and guests during the summer period. He added that high prices would not exempt airlines from obligations to compensate passengers for delays or cancellations under existing rules.


The Commission’s package blends short-term supply monitoring and clarification of operational rules with a policy push toward cleaner aviation fuels. The measures aim to limit disruptions to passengers and reduce the bloc’s vulnerability to supply shocks stemming from risks in the Strait of Hormuz and regional military developments.

Risks

  • A sustained blockade of the Strait of Hormuz would be catastrophic for Europe and the world, threatening oil and liquefied natural gas flows and jet fuel availability - impacting energy and transportation sectors.
  • Technical differences in alternative imports - for example, U.S. Jet A's higher freezing point compared with the European standard - could complicate operations and supply integration in aviation and refining.
  • High jet fuel prices could strain airline finances and passenger relations while offering no exemption from compensation obligations for delays or cancellations - affecting airlines and consumer-facing travel sectors.
