European Union weighs more American jet fuel, cleaner aviation industry amid strains from Iran war

The European Union will provide guidance to airlines on how to handle issues such as airport slots, passenger rights, and public service obligations in the event of jet fuel shortages because of the Iran war, the bloc’s transport chief said on Tuesday.

Apostolos Tzitzikostas said there were no shortages “as of today” but warned a prolonged blockage of the Strait of Hormuz would be “catastrophic” for Europe and the global economy.

About one-fifth of the world’s oil and liquefied natural gas transited Hormuz before the US and Israel began bombing Iran on February 28. The EU imports 30% to 40% of its jet fuel needs, with about half coming from the Middle East.

The European Commission is due to present a broader package of energy and transport measures on Wednesday. Tzitzikostas said it would set up a new “fuel observatory” to monitor supplies, starting with jet fuel.

“If real supply issues arise, our emergency stocks must be put to best use. Any national release of fuel must be done in full transparency to avoid market distortions,” he told reporters after a meeting of the EU’s transport ministers.

He added there were no signs of “widespread cancellations” in the coming weeks or months. The International Energy Agency warned last week that physical shortages could start as soon as June, but European airlines currently report only higher prices.

A spokesperson for IAG, owner of British Airways and Iberia, said it was “not seeing disruption to jet fuel supply in our main airports, but our airlines are already facing rising fuel costs.” German logistics group DHL said it could secure fuel for its cargo planes in Europe into June, though the outlook for its Asian operations remained uncertain.

Opportunity for sustainable aviation fuel

As part of the response, the Commission wants to use the crisis to accelerate the development of the sustainable aviation fuel (SAF) and synthetic fuels sectors to cut reliance on imports from the Middle East, Tzitzikostas said, confirming a Reuters report last week.

Global airline group IATA warned last year that SAF production remains too low to meet green fuel targets and costs up to five times more than conventional jet fuel.

The EU’s anti-tankering rules, aimed at preventing airlines from loading excess fuel at cheaper airports, already allow exemptions in the event of shortages, but the Commission will clarify the framework on Wednesday.

The Commission is also examining alternative imports, including US Jet A fuel, which has a higher freezing point than the European standard.

“There is no need at this point to intervene in how people live, work, or travel… Europe is ready to welcome all the tourists and guests during the summer period,” Tzitzikostas said, adding that high fuel prices would not justify waiving passenger compensation for delays or cancellations.
