Sustainable Aviation Fuels: Offtake Manual Summary

Introduction:
The aviation industry aims to reduce emissions by 65% by 2050 through Sustainable Aviation Fuels (SAF), which are produced from renewable sources and can reduce carbon intensity by up to 100% compared to conventional jet fuel. SAF is chemically identical to traditional jet fuel and requires minimal aircraft modifications.

Key Stakeholders:

• Airlines: Face challenges in procurement, policy compliance, and technical integration.
• Corporate Buyers: Use SAF to offset Scope 3 emissions via book-and-claim systems (e.g., CORSIA).
• Producers: Need policy support and long-term contracts to scale SAF production.

Policy and Regulatory Compliance:
CORSIA mandates emissions offsetting using SAF, requiring clear documentation for life-cycle analysis and sustainability certification. National policies like the EU’s ReFuelEU aim to enforce SAF usage by 2025.

Economic Challenges:
SAF is currently twice as expensive as fossil jet fuel due to limited feedstocks and high production costs. Economies of scale and policy incentives (e.g., carbon pricing) are key to reducing costs.

Best Practices:

• Early Engagement: Involving procurement, sustainability, and finance departments early in SAF contracts.
• Book-and-Claim Systems: Allow corporations to track emissions reductions without managing physical fuel logistics.
• Supplier Diversification: Mitigates risks from limited feedstock availability and infrastructure gaps.

Conclusion:
SAF is critical for aviation decarbonization, and collaboration among airlines, governments, and producers through market-driven contracts and policy support is essential for accelerating adoption and reducing costs.
