EU Carbon Market Expansion Triggers Backlash From ICAO and IATA

A controversial proposal by the European Commission to overhaul the European Union Emissions Trading System (EU ETS) has drawn swift opposition from aviation leaders, international regulators, and environmental advocates.

Presented on July 17, 2026, the legislative draft aims to expand the EU carbon market’s scope to include outgoing international flights while simultaneously softening emission rules for heavy industry. The Commission cited a changing “geopolitical and economic context” that has placed European businesses under “growing pressure” as the primary rationale for adjusting the carbon framework.

The proposed reform introduces a carbon price on international aviation originating from EU airports starting in 2029, restricted to flights traveling within a 5,000-km radius. Under this geographic threshold, a route from Paris to Dubai would fall under the carbon market, whereas a longer flight from Paris to New York would remain exempt.

Industry group Transport & Environment (T&E) reported that the 5,000-km limitation leaves 47% of European aviation exempt from carbon pricing, representing approximately €4.2 billion (US$4.5 billion) in uncollected revenue had all departing flights been included.

“Due to industry pressure, only a portion of routes will be covered, and the longest, most polluting flights will remain exempt,” said Diane Vitry, T&E. “This can only be a starting point. The ball is now in the court of member states. They must, at a minimum, support this compromise while pushing to progressively expand coverage before the next review. Aviation has to pay for all its emissions, just like any other sector of the economy.”

Aviation governance bodies and trade groups criticized the proposal for introducing regulatory overlap and territorial overreach. The International Civil Aviation Organization (ICAO) warned that extending the EU ETS to international flights risks creating double obligations for airlines under carbon compliance rules and undermines the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).

ICAO noted that while the EU previously helped establish international consensus around CORSIA as the single global market-based measure for international aviation emissions, the July 17 proposal conflicts with maintaining a harmonized global policy.

“The international cooperation and multilateralism represent the path to advance in environmental protection for aviation and achieve the goal of net-zero carbon emissions by 2050,” ICAO stated, urging member states to maintain support for CORSIA following a unanimous mandate passed during its 42nd Assembly in 2025 to strengthen its environmental framework.

The International Air Transport Association (IATA) expressed strong frustration with the extraterritorial implications of the policy, warning of potential regulatory disputes, increased operational costs for airlines, and higher ticket prices for consumers.

“The European Union is repeating a historical mistake. The consequences will be detrimental: generating friction over extraterritoriality, slowing down global decarbonization, and eroding European competitiveness, while European travelers and businesses pay the price,” said Willie Walsh, Director General, IATA.

Walsh suggested that the EU should instead focus on enhancing CORSIA, increasing Sustainable Aviation Fuel (SAF) allowances, and implementing a book-and-claim system for alternative fuels.

Beyond aviation, the Commission’s proposal softens broader industrial carbon rules by extending free emission allowance allocations until 2038, four years past the previous 2034 phase-out date. The draft allows companies to receive 80% of free allowances upfront if they possess approved decarbonization investment plans, releasing the remaining 20% once investments materialize. To support maritime transition, the plan allocates 110 million ETS allowances toward clean maritime fuels, green e-fuels, and battery-powered vessels.

Since its launch in 2005, the EU ETS has raised over €270 billion (US$307.85 billion) for industrial decarbonization, energy modernization, and innovation, helping cover sectors reduce emissions by 50%. However, climate policy groups argue the proposed adjustments undermine those gains.

“The EU ETS has proven that putting a price on carbon works,” said Wopke Hoekstra, European Commissioner for Climate, Net Zero and Clean Growth. “It has reduced emissions, strengthened Europe's energy security, and mobilized investments across our economy. The proposed revision brings together three key objectives: climate action, competitiveness, and independence.”

Critics strongly contested Hoekstra's assessment. Linda Kalcker, Executive Director of paneuropean think tank Strategic Perspectives, described the overhaul as a “Trojan horse” that penalizes forward-looking firms and risks making the EU's 2040 target, to cut net greenhouse gas emissions by 90% compared to pre-industrial levels, unnecessarily costly.

“It looks like a gift for companies to delay reducing their emissions, when in reality it places them at a competitive disadvantage against accelerating Chinese companies. Once again, political pressure outweighs economic and market reality,” Kalcker said.

Chiara Martinelli, Director of Climate Action Network (CAN) Europe, added: “Weakening the ETS now is a gift to big emitters that have prioritized profit distribution to shareholders over investing in cleaner production, at the expense of citizens, future generations, and those companies that have already bet on climate-friendly solutions.”

The proposal now moves to the European Parliament and the Council of the European Union, where legislative positions will be negotiated before a final text can be formally adopted into law.
