SAF-Blended Aviation Fuel

SAF-Blended Aviation Fuel

Context

The Indian government amended the Aviation Turbine Fuel (ATF) (Regulation of Marketing) Order, 2001. This landmark regulatory shift officially brings Sustainable Aviation Fuel (SAF) and SAF-blended mixtures under the government’s administrative and marketing ambit, signaling a decisive move toward greening the aviation sector.

About the News

Definition: Sustainable Aviation Fuel (SAF) blended with traditional ATF is a "drop-in" fuel solution. It is designed to significantly reduce the aviation industry's carbon footprint without requiring any modifications to existing aircraft engines, fuel storage, or distribution infrastructure.

Composition and Standards:

• Chemical Similarity: SAF consists of aviation-grade hydrocarbons that are chemically nearly identical to petroleum-based ATF.
• Renewable Feedstocks: It is produced from alternative sources, including agricultural crops, biogenic residues (like used cooking oil), and municipal solid waste.
• Rigorous Certification: To ensure safety and performance, SAF must meet ASTM International standards and be recognized by the International Civil Aviation Organization (ICAO).

Technical Specifications in India:

• IS 1571: The Bureau of Indian Standards (BIS) specification for petroleum-based ATF and co-processed SAF.
• IS 17081: The dedicated standard for SAF that is physically blended with traditional ATF.

New Changes

The amendment to the ATF Control Order introduces several structural changes:

• Expanded Definition: The legal definition of "Aviation Turbine Fuel" now formally includes SAF co-processed in refineries and SAF blended with conventional fuel.
• Regulatory Oversight: By bringing SAF under the 2001 Order, the government can now effectively regulate the quality, marketing, and supply chain of green fuels.
• Mandatory Blending Roadmap: India has established clear blending targets for international flights:
  • 1% blending by 2027
  • 2% blending by 2028
  • 5% blending by 2030

Key Features and Significance

• Emission Reduction: SAF offers a lifecycle greenhouse gas (GHG) emission reduction of up to 80% compared to conventional fossil-based jet fuel.
• CORSIA Alignment: The move aligns India with the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), which enters its mandatory phase in 2027.
• Operational Compatibility: As a "drop-in" fuel, it maintains the fundamental safety and performance parameters of modern aviation without needing new aircraft technology.
• Global Parity: This amendment brings India in line with the UK, EU, and Singapore, ensuring Indian carriers remain competitive and compliant in international airspace.

Implications

• Economic Relief: By meeting blending targets, Indian airlines can reduce their reliance on purchasing expensive international carbon credits.
• Domestic Production: The mandate provides a clear demand signal, encouraging Indian petroleum refineries to scale up domestic SAF production capabilities.
• Sustainability Leadership: Positions India as a proactive participant in the global transition to net-zero aviation, leveraging its vast biomass resources for fuel production.

Conclusion

The integration of SAF into the ATF regulatory framework marks a pivotal transition for Indian aviation. By setting clear blending targets and standards, the government is creating a structured pathway for the industry to decouple growth from carbon emissions, ensuring constitutional and international environmental commitments are met.
