The European Commission is preparing an Energy Action Plan that would require companies to avoid air travel for work purposes and push EU member states to subsidise train ticket prices, according to a draft document seen by El País. The measures, to be presented next week by Commission President Ursula von der Leyen, are a direct response to soaring energy costs triggered by the closure of the Strait of Hormuz — through which 20% of the world's oil and gas trade passes — following the conflict involving the United States, Israel, and Iran. European airports have already warned of potential aviation fuel shortages within weeks, as 40% of airline fuel used in Europe originates from the Middle East, making the push to reduce air travel both a climate and an energy security priority.
