EU ETS review proposes extending carbon costs to more long-haul flights

EU ETS review proposes extending carbon costs to more long-haul flights A mid-July Commission review raises aviation scope while a separate cap-loosening proposal points the other way on EUA supply. The European Commission's mid-July review of the EU Emissions Trading System includes a proposal to phase in carbon coverage for a wider set of long-haul flights, according to Quantum Commodity Intelligence. Aviation currently receives a broad exemption for intercontinental routes, and extending coverage would force more airlines to surrender EUAs for full journey distances rather than only the European leg.⁶ An Italian carbon market consultant told Montel on July 1 (2026-07-01) that the review will fail to fix the scheme's underlying flaws on auction access and design, including a potential return to more free allocation of allowances. Free allocation and scope extension cut in opposite directions on the supply-demand balance — wider coverage adds demand, more free allowances dilute it.⁶ The Commission's timeline makes this harder. Analysts described the proposed Q1 2027 deadline to agree carbon market reforms as "ambitious" and "extremely challenging," with the ongoing US-Israeli war with Iran adding legislative friction, Montel reported on Thursday (2026-05-21).¹ The conflict complicates aviation economics directly. Some 20% of the world's jet fuel passes through the Strait of Hormuz, James Noel-Beswick of Sparta Commodities noted. Before hostilities erupted, IATA had forecast the Middle East would generate 17% of the $41bn in net profits it expected for the global airline industry in 2026. Those projections are under pressure as carriers reroute around closed airspace and absorb higher fuel costs. Any new carbon liability lands on an industry already managing those additional costs.³ Separately, Carbon Market Watch warned in May that a proposal to slow the pace of ETS cap tightening could add allowances to the market for another three years. That supply-side measure, if enacted alongside wider aviation coverage, would create offsetting forces whose net effect on the EUA price path is genuinely unclear.² ICE EUA December settled at €78.48/tCO2 on Friday (2026-07-17). The ICE Endex TTF front-month fell 1.5% on the same day to €54.82/MWh, a move driven by mild weather forecasts rather than any carbon market development. German power sat at €120.05/MWh. Under the cross-sector link between EUA costs and gas-fired generation margins, any net tightening of the ETS would lift the floor under European power prices. [LIVE PRICES] The policy debate extends beyond cap mechanics. Andrei Marcu, who leads a climate roundtable, has argued the ETS needs to manage carbon costs rather than just prices — a signal that the Commission may resist a cap slowdown that collapses allowance values below the level needed to push industrial decarbonisation decisions.⁵ The legal path for extending aviation coverage is narrow. The current exemption for flights departing the European Economic Area traces back to the 2011 "stop the clock" decision, which suspended ETS application to international aviation while ICAO developed a global alternative. ICAO's Corsia scheme remains voluntary. Reversing the intercontinental exemption would invite legal challenges from non-EU carriers and a legislative process that realistically runs past 2027.¹ Energy Aspects flagged in April (2026-04-14) that EU initiatives including the Industrial Decarbonisation Bank and an ETS investment booster scheme could push more allowances into the market from next year, adding a further supply-side pressure on the EUA price.⁴ The legislative text the Commission releases will determine whether aviation coverage is a concrete new demand source or a consultation placeholder. If the draft contains specific language on scope, the EUA complex would need to price in demand that has been largely discounted. If it reverts to a consultation clause, the market's focus shifts back to the cap pace and whether Brussels can reach consensus on ETS reform while the Iran crisis competes for political attention.^1,2
