The aviation sector is in a defining moment. Strong growth in global demand is reinforcing aviation’s role in connectivity and economic development, even as mounting pressures—from geopolitical uncertainty to climate constraints—intensify the challenge of decarbonization.
Achieving net zero by 2050 is both a strategic and an immediate operational priority, requiring coordinated action across the aviation industry, energy sector, and governments.
Aviation growth is set to grow – and so are expectations
As demand for air travel continues to grow, so do expectations for the industry to decarbonize. The industry has committed and remains firmly engaged to achieving net zero carbon emissions by 2050, but the pathway to that goal is proving complex due to operational, technological, political and other constraints.
From clean technology costs and deployment challenges, to geopolitical and systemic disruptions, the external environment has evolved rapidly since the World Economic Forum published its first Global Aviation Sustainability Outlook.
Industry leaders face rising costs for clean technologies, persistent supply chain disruptions and geopolitical tensions, while continuing to prioritize safety, operational efficiency, passenger experience, and affordability.
Support for the International Civil Aviation Organization’s (ICAO) 2050 net zero goal remains widespread, with a shift toward implementation over aspiration.
What was once a long-term ambition has become an immediate operational challenge – reshaping decisions on fuel, infrastructure, investment, and policy across the entire aviation ecosystem.
Investment in cleaner aviation means more jobs, better skills, new economic opportunities and greater energy security, independence, and resilience.
Airports central to the aviation system
Airports are becoming an integral part of the aviation energy transition through decarbonizing their own operations and collaborating with stakeholders to achieve the ACI Long Term Carbon Goal.
At the centre of the aviation system, airports are not merely infrastructure assets but economic engines and energy hubs enabling the broader transition, by:
- Supporting Sustainable Aviation Fuel (SAF) distribution, improving energy efficiency, electrifying ground operations, exploring hydrogen projects, increasing their efficiency as operational platforms using AI and data.
- Advancing circularity initiatives across airport operations and infrastructure, reflecting growing innovation in resource use, waste reduction, value chain collaboration, and sustainable asset management.
- Becoming resilient logistics centers adapting to climate and energy system risks.
This shift reflects a broader reality: decarbonization is not only about aircraft—it depends on reliable access to renewable energy, infrastructure readiness and system-wide coordination.
Sustainable Aviation Fuel (SAF): the cornerstone of decarbonization
SAF remains the main scalable solution to reduce aviation emissions in the near and medium terms. Production is increasing, new plants are coming online, and policy support is expanding. However, progress is uneven. It still represents a small share of total fuel use, limited by feedstock mobilization, facilities development, investment risk, and policy uncertainty.
Without rapid scale-up, SAF constraints will slow aviation decarbonization.
Coordinated action and 2026 priorities: driving aviation decarbonization
The new Global Aviation Sustainability Outlook 2026 highlights a clear message: sustainable aviation requires coordinated system-wide action.

Key priorities include:
- Governments: shaping SAF and renewable energy policies, strengthening regulatory frameworks, and enabling global policy alignment and investment certainty.
- Airports and airlines: driving operational transformation, improving efficiency, implementing decarbonized operational practices, and building climate-resilient airport infrastructure.
- Manufacturers: developing next-generation aircraft technologies and enabling cleaner aircraft operations.
- Energy providers: scaling SAF production and expanding access to cleaner energy sources;
- Financial institutions: mobilizing long-term capital to support infrastructure development and accelerate deployment of decarbonization solutions.
- Industry as a whole: leveraging AI and digital tools to improve efficiency and emissions tracking, while enabling system-wide operational efficiency and coordination across the aviation ecosystem.
The next five years will be critical in determining whether aviation remains on track to meet its decarbonization objectives.
The future of sustainable aviation
The destination has not changed: net zero aviation by 2050.
The transition is constrained by cost pressures, supply chain challenges, and infrastructure gaps, underscoring the need for accelerated action and investment across States, industry, energy and finance sectors.
Aviation will continue to grow, and the challenge is ensuring decarbonization keeps pace. Success depends on turning ambition into action, policy into investment, and innovation into scalable solutions.
With a pragmatic approach, grounded in collaboration and collective action, the global aviation community can continue to connect the world while advancing the transition to sustainability.
FAQs
What is SAF?
SAF is a non-fossil alternative to conventional jet fuel, produced from different feedstocks such as waste, biomass or synthetic processes using clean energy. Meeting globally-recognized sustainability criteria, it can:
- Cut lifecycle emissions significantly.
- Be used in existing aircraft and fuel systems up to a 50% blends
- Deliver immediate emissions reductions without waiting for new aircraft technologies.
Why is SAF important for aviation?
SAF is currently the most scalable solution to reduce aviation emissions without requiring new distribution infrastructure or aircraft technology.
What are the biggest challenges for sustainable aviation?
Key challenges include building the supply chain, access to feedstock including clean energy, technology readiness (e.g., e-SAF), SAF cost and availability, policy fragmentation, facilities deployment and investment needs.
