Sustainable Aviation

Advancing greener aviation alongside operational safety

about Sustainable AviATION

Aviation faces increasing pressure to reduce its environmental impact while maintaining the highest standards of safety and operational effectiveness. Climate change, emissions, noise, and local air quality are central considerations shaping the future of the industry.

IFALPA advocates for a balanced, evidence-based approach that integrates environmental objectives with operational feasibility, technological maturity, and economic sustainability. Through its engagement with regulators and industry stakeholders, IFALPA ensures that safety and real-world operational considerations remain central to decision-making.

Sustainable aviation fuels, operational efficiencies, and emerging technologies all contribute to reducing aviation’s environmental footprint, provided they are implemented in a way that maintains safety and system integrity.

Sustainable Aviation Fuels

The development and deployment of SAF as a key pathway to reducing lifecycle emissions, ensuring that fuel solutions are safe, scalable, and operationally viable.

Non CO₂ Effects & Contrails

The impact of non CO₂ emissions, particularly persistent contrails and induced cirrus, and the exploration of operational strategies to mitigate their climate effects.

Operational Efficiency

Optimization of flight operations and ATM efficiency to reduce fuel burn and emissions, including trajectory optimization and improved coordination across the air traffic system.

Innovation & New Energy

The role of new aircraft technologies, alternative propulsion systems, including hydrogen, and advanced energy solutions in supporting long term decarbonization.

Balancing Climate with Operational Safety

Reducing aviation’s environmental impact involves complex trade-offs between emissions reduction, airspace capacity, fuel efficiency, and operational safety. Measures such as contrail avoidance, alternative fuels, and trajectory optimisation must be carefully assessed to ensure environmental benefits do not introduce unintended operational risks.

IFALPA advocates for a cautious, evidence-based approach to climate initiatives, ensuring that changes to flight planning, routing, and in-flight decision-making are supported by accurate data, reliable forecasting, and effective decision-support tools. This is particularly important given ongoing uncertainties, including non-CO₂ effects.

Long-term progress requires coordinated action across the aviation system, including aircraft technology, operational improvements, infrastructure, and market-based measures. IFALPA works with stakeholders to promote solutions that are environmentally effective, operationally sound, and globally harmonised.
