India’s Push for Sustainable Aviation Fuels Faces Federal Challenges

Quick Summary:

• A U.S. federal spending law passed in July 2025, known as the “One Big Beatiful Bill” Act, reduced funding for renewable and lasting aviation fuel (SAF) development.
• Aviation contributes approximately 2.5% of global carbon emissions, and lowering emissions from aircraft is particularly challenging due to a lack of viable energy-dense alternatives to conventional jet fuel.
• Sustainable aviation fuels are derived from renewable resources like used cooking oil, algae, agricultural waste, or even trash. these fuels work with existing aircraft engines but are considerably more expensive than conventional jet fuels.
• Global production of SAF remains minimal-only around 2 million metric tons in 2025-making up less than 1% of the global demand for aircraft fuel.
• Companies like General Electric and Rolls-Royce have developed engines capable of running on SAF blends up to 50%, though cost differences (e.g., $5.20 per gallon for SAF vs. $2.34 per gallon for Jet-A in 2024) remain a major barrier to adoption.
• Europe has implemented mandates requiring at least 2% sustainable fuel in jet fuel supplied at airports since January 2025; these regulations will increase gradually over time.

Indian Opinion Analysis:

The reductions in U.S.-based government support for sustainable aviation fuels could have broader implications on global efforts toward decarbonizing air travel, including potential ripple effects that reach india’s growing aviation sector. india’s civil aviation is expanding rapidly and poses similar concerns regarding carbon emissions amidst its attempts at environmental sustainability goals.

While technological advancements hold promise-for instance, creating biofuels via nonfood sources or genetically modified microbes-the high costs and limited supply make widespread use challenging at present. For India specifically, creating scalable infrastructure for collecting and processing raw materials as well as policy-driven initiatives akin to EU mandates might be critical steps forward.

This development underscores the need for international collaboration among governments and industries alike so that progress toward carbon-neutral fuels isn’t hindered by isolated geopolitical decisions.
