The International Air Transport Association (IATA) will hold its fourth World Sustainability Symposium (WSS) in Brussels, Belgium, on October 13-14, 2026, bringing together influential leaders from aviation, energy, finance, technology, academia and government to address one of the industry’s most pressing challenges: achieving net zero carbon emissions by 2050. The high-level gathering will focus on the policies, investments and technological solutions required to accelerate aviation’s transition toward a more sustainable future while protecting the economic and social benefits created by global air connectivity.
The choice of Brussels gives the symposium particular strategic importance, as the city remains a major center for European policymaking and the development of aviation regulations that can influence the industry’s future. The event is expected to create a direct platform for airline executives and sustainability specialists to engage with policymakers responsible for shaping the regulatory frameworks governing aviation’s energy transition. At the heart of the discussions will be a critical question facing the global industry: how to decarbonize aviation at the required speed without undermining connectivity, competitiveness and affordable air travel.
Aviation’s Net Zero Goal Faces a Race Against Time; IATA
The global air transport industry has committed to achieving net zero carbon emissions by 2050, but IATA has emphasized that airlines cannot accomplish this transition independently. The transformation will require significantly greater renewable energy production, new infrastructure, technological innovation, financial investment, and policies designed to support the entire aviation ecosystem. According to IATA, the industry’s biggest challenge is increasingly not a lack of ambition but the difficulty of developing and scaling multiple interconnected solutions quickly enough.
Marie Owens Thomsen, IATA’s Senior Vice President for Sustainability and Chief Economist, stressed that aviation’s energy transition depends on cooperation across sectors. She highlighted the need for governments, energy producers, investors and technology developers to work alongside airlines rather than treating aviation decarbonization as an isolated industry challenge. Her message reflects a growing recognition that the future of sustainable aviation will depend heavily on whether governments and industries can create the conditions necessary to expand cleaner energy solutions at a commercially viable scale.
Europe has already introduced ambitious objectives for reducing aviation emissions, but IATA argues that policies must better recognize the complex interdependencies involved in the transition. Bringing the World Sustainability Symposium to Brussels is therefore intended to help close the gap between policy ambition and practical implementation, creating greater consensus among transportation, energy, finance and government professionals. With energy security and economic competitiveness becoming increasingly important global concerns, the discussions are expected to carry significant implications for the future direction of European and international aviation.
Sustainable Aviation Fuel Takes Center Stage in the Energy Transition
A major focus of the symposium will be the challenge of scaling solutions for aviation’s energy transition, particularly Sustainable Aviation Fuel (SAF) and other lower-carbon alternatives. The agenda will examine opportunities described as the industry’s more immediately achievable solutions, including HEFA Sustainable Aviation Fuel, Low Carbon Aviation Fuels (LCAF) and co-processing technologies. Increasing the availability and affordability of these fuels remains one of the most important challenges facing airlines seeking to reduce their carbon footprint.
The symposium will also examine how governments and international institutions can design and harmonize policies that support global, transparent, competitive and liquid markets for SAF, carbon credits and other decarbonization solutions. Industry leaders have repeatedly emphasized that fragmented policies and limited fuel supplies could slow the transition and create unequal competitive conditions for airlines operating in different markets. Brussels will therefore provide an important setting for discussions on how international cooperation can help establish stronger and more predictable market conditions for sustainable aviation.
Beyond fuel, participants will explore emerging technologies, the impact of non-CO₂ emissions, and sustainability considerations throughout the entire lifecycle of an aircraft. This broader approach recognizes that reducing aviation’s environmental impact will require progress across multiple areas rather than relying on a single technological breakthrough. From aircraft manufacturing and operations to fuel production and carbon management, the industry’s transition will require coordinated innovation throughout the aviation ecosystem.
Global Aviation, Energy and Finance Leaders Set to Shape the Debate
The World Sustainability Symposium will bring together a wide range of senior executives, policymakers, regulators, investors, fuel producers and sustainability specialists. Confirmed speakers include Roberto Alvo, CEO of LATAM Airlines Group; Eddy Liégeois, Head of Unit for Aviation Policy at DG MOVE; Cynthia Ní Mhurchú, a Member of the European Parliament; and Paolo Frankl, Head of the Renewable Energy Division at the International Energy Agency.
Other confirmed participants include Leif Holmberg, Board Co-chair of the Green Climate Fund and Deputy Director at Sweden’s Ministry of Foreign Affairs; Margarita Cabrera Botero, Head of Climate Business at the Multilateral Investment Guarantee Agency of the World Bank Group; Jonathon Counsell, Group Head of Sustainability at IAG; and Bertrand de Lacombe, Vice President for Sustainability, Regulatory and External Engagement at Airbus. Representatives from airports, renewable fuel companies, financial institutions and technology sectors will also contribute to the discussions, underlining the symposium’s ambition to bring the entire aviation value chain into a single conversation.
A Landmark Week for Europe’s Aviation Industry
For the first time, the World Sustainability Symposium and Wings of Change Europe (WOCE) will take place consecutively at the same venue, creating an extended week of discussions involving sustainability experts, airline executives, regulators and policymakers. Participants registered for the WSS will receive complimentary access to WOCE on October 15, 2026, allowing them to take part in a broader examination of the strategic challenges and opportunities shaping Europe’s aviation sector.
Together, the two events are expected to provide a comprehensive platform for examining the difficult balance between decarbonization, competitiveness, connectivity and economic growth. The discussions will bring industry leaders and policymakers together at a particularly important moment, as aviation faces increasing pressure to reduce emissions while continuing to meet growing global demand for air travel.
As the industry moves closer to its 2050 net zero deadline, the Brussels symposium will serve as more than another international aviation conference. It will represent a critical opportunity to determine whether the policies, investments and technologies needed for aviation’s energy transition can be developed and scaled quickly enough. With sustainable fuel production, infrastructure development and international policy coordination emerging as decisive challenges, the conversations taking place in Brussels could help shape the path toward a cleaner, more resilient and globally connected aviation industry.
