India has crossed the 50% threshold in sustainable aviation fuel readiness, according to a joint report by Boeing and the Roundtable on Sustainable Biomaterials (RSB) reported by NDTV Profit.

The milestone places India past the halfway point on a readiness scale that measures how prepared a national aviation ecosystem is to adopt and scale sustainable aviation fuel (SAF). The report, produced by the US airframer together with RSB — the Switzerland-based sustainability standards body — frames the result as a signal of India's progress toward decarbonising one of the world's fastest-growing civil aviation markets.

For airlines and regulators in India, the readiness figure arrives as pressure builds globally to mandate SAF blending. The European Union's ReFuelEU rules and the United Kingdom's SAF mandate have set blending obligations for carriers, and Indian policymakers have been weighing comparable frameworks for a market served by carriers including Air India, IndiGo and Akasa Air.

Boeing's involvement in the assessment reflects the OEM's broader interest in SAF supply chains, since every aircraft it delivers today is certified to fly on approved SAF blends, while 100% SAF certification remains dependent on engine makers and fuel qualification standards.

The report does not by itself commit India to a blending mandate or a production target. Readiness scores measure enabling conditions — feedstock availability, regulatory capacity, refining infrastructure and airline operational preparedness — rather than actual SAF volumes delivered to Indian airports.

Crossing the 50% mark nonetheless signals that more than half of the assessed conditions for large-scale SAF adoption in India are now in place, a position that could inform the timeline of any future government blending requirement and shape investment decisions by fuel producers weighing Indian feedstock, from used cooking oil to agricultural residues.

The full Boeing-RSB report is expected to provide the sector-by-sector breakdown behind the readiness score, giving airlines, refiners and policymakers a baseline against which to measure India's next moves on aviation decarbonisation.
