Aviation

The aviation industry accounts for approximately 2% of all global CO₂ emissions. With projections suggesting this will continue to rise in line with air travel growth, the urgency for decarbonization is clear. The sector's reliance on fossil fuels, coupled with the long investment horizons and fleet renewal cycles, means immediate and decisive action is essential. Embracing sustainability not only addresses climate change, but also aligns with growing regulatory pressures and consumer demand for greener travel options.

Decarbonization Challenges in the Aviation Industry

• Sustainable Aviation Fuels (SAFs) Production: SAFs have the potential to reduce emissions by up to 80%, but their production is still limited and costly. Scaling up SAF production to meet global demand is a major challenge due to feedstock constraints and the need for new production facilities​.
  
• Technological Limitations: The development and deployment of new technologies such as electric and hydrogen-powered aircraft are progressing but face significant hurdles. For instance, electric aircraft currently have limited range and payload capacity, while hydrogen-powered aircraft require substantial advancements in fuel storage and infrastructure​.
  
• Economic Factors: Transitioning to sustainable operations requires substantial investment in new technologies, infrastructure, and SAF production. The high costs associated with these changes can be a significant barrier, especially for airlines already operating on thin margins​.

Next Steps for the Aviation Industry

Overcoming these hurdles requires a multi-faceted approach that leverages innovation, policy support, and collaborative efforts. The following steps outline the essential actions the industry must take to advance toward a sustainable future, ensuring alignment with global climate goals and consumer expectations.

• Invest in SAF Production: Scaling up SAF production is critical. This involves not only increasing the capacity of existing biofuel plants, but also developing new power-to-liquid plants to overcome feedstock limitations. Airlines and fuel producers should work closely with governments to secure necessary incentives and regulatory support.
  
• Enhance Collaboration: Multi-stakeholder collaboration is vital. Airlines, fuel producers, technology developers, and regulatory bodies must work together to create a cohesive strategy for decarbonization. Initiatives like the Clean Skies for Tomorrow coalition exemplify how collective action can drive meaningful progress​.
  
• Accelerate Technological Innovation: Continued investment in R&D for electric and hydrogen-powered aircraft is essential. This includes improving battery technology, enhancing hydrogen storage solutions, and developing hybrid aircraft to maximize range and efficiency​.

By addressing these challenges and taking proactive steps, the aviation industry can make significant strides toward a sustainable future. ENGIE Impact is committed to supporting these efforts through innovative solutions and strategic partnerships, driving the transition to a low-carbon aviation sector.
