In a landmark event for the aviation industry, Hong Kong will host the third edition of the International Air Transport Association’s (IATA) World Sustainability Symposium (WSS) on October 21-22, 2025. The event, held for the first time in Asia, will bring together industry leaders from aviation, energy, finance, and policy sectors to discuss strategies for achieving net-zero carbon emissions in aviation by 2050. Cathay Pacific has been chosen as the host airline for this pivotal event, which promises to be a crucial step toward decarbonizing the aviation sector.
As the aviation industry works towards its ambitious target of net zero CO2 emissions by 2050, the symposium will serve as a vital platform for collaboration. Aviation leaders, policymakers, and stakeholders will explore key challenges in advancing sustainable practices, focusing on the development and scaling of Sustainable Aviation Fuel (SAF). Hong Kong is expected to play a critical role in the future of SAF production, with the city positioned as a potential hub for the sustainable fuel in Asia.
The event aims to foster discussions around the obstacles hindering the growth of SAF production, as well as attracting necessary investments to support aviation’s energy transition. With global aviation stakeholders coming together, the symposium will focus on identifying practical and innovative solutions to ensure the sector’s environmental and financial sustainability.
Strategically scheduled after the 42nd ICAO Assembly and ahead of COP30, the WSS will bridge these significant milestones in the global climate agenda. The symposium will serve as a timely rallying point for the aviation industry to push for stronger government policies supporting SAF production and decarbonization efforts. It will provide a comprehensive look at the key actions required to accelerate progress, ensuring that the aviation sector can meet its decarbonization goals.
The WSS will tackle the significant challenges of decarbonizing aviation, which faces a projected $4.7 trillion cost to meet the required energy transition. A central topic will be removing barriers to expanding SAF production, with a focus on establishing a sustainable and scalable fuel supply chain. Experts will also discuss ways to attract funding for the decarbonization process and integrate emerging technologies from both established industry players and new startups. Increasing collaboration across the aviation value chain will also be a key focus.
The event’s discussions will revolve around the need for urgent action and collaboration across all sectors to overcome the barriers hindering decarbonization. Government policymakers, aerospace manufacturers, fuel producers, and other stakeholders will be encouraged to take swift, coordinated actions to support aviation’s transition to sustainability.
The symposium will feature leadership addresses from influential figures in the aviation industry. Ronald Lam, the CEO of Cathay Pacific Group, will deliver a welcome address, followed by a keynote speech from Mable Chan, the Secretary for Transport and Logistics of Hong Kong SAR. These leaders will discuss the importance of collaboration and the role of Hong Kong as a key player in sustainable aviation.
A panel discussion will bring together global leaders, including Patrick Healy, Chair of the Cathay Group, and Willie Walsh, IATA’s Director General, to review the aviation industry’s progress in decarbonization. Other industry experts from organizations like the Hong Kong Green Finance Association, Kuehne+Nagel, HSBC, and WTW will contribute their insights into the solutions required for a carbon-neutral aviation future.
During the two-day event, the following topics will be explored:
The WSS is designed to be a platform for radical collaboration, where diverse sectors come together to find practical solutions to the challenges of decarbonizing the airline industry. The symposium emphasizes the importance of a holistic approach to sustainability, recognizing that aviation’s decarbonization is part of a larger global energy transition that spans multiple industries, from agriculture to technology.
Marie Owens Thomsen, IATA’s Senior Vice President of Sustainability and Chief Economist, highlighted that achieving net-zero emissions by 2050 requires coordinated efforts across multiple sectors, including policy, energy, finance, and technology. The event will be a critical moment for pushing forward the actions required to meet the aviation industry’s sustainability targets.
The 2025 IATA World Sustainability Symposium in Hong Kong is set to be a significant milestone in the aviation industry’s journey toward achieving net-zero CO2 emissions by 2050. The event will serve as a crucial platform for collaboration and action, with a strong focus on developing and scaling sustainable aviation fuel, attracting investment, and fostering cooperation across the value chain. As the world looks ahead to COP30, the symposium in Hong Kong will play a key role in turning the aviation industry’s decarbonization pledges into tangible actions, ensuring a sustainable future for global air travel.
