The Centre is examining a targeted fiscal and financing package to help kick-start India's sustainable aviation fuel industry, in a move that could shape the economics of one of the country's most closely watched clean-energy transitions. The proposed framework, according to people familiar with the matter, includes viability gap funding for production facilities, concessional finance and support for feedstock procurement, reflecting the government's view that early-stage SAF projects are unlikely to reach commercial scale without public intervention.
Policy Push
The discussion comes at a time when global aviation is under mounting pressure to cut emissions, but the high cost of SAF remains the single biggest barrier to adoption. Conventional jet fuel is still materially cheaper than SAF, and the price gap is especially difficult for airlines and refiners to absorb in a price-sensitive market such as India. Officials are therefore weighing a package designed not merely to encourage demand, but to de-risk supply creation at the plant level, where capital intensity and feedstock uncertainty have deterred private investment.
Viability gap funding would help bridge the difference between project costs and the revenue that early plants can realistically generate. Concessional finance, if approved, could lower borrowing costs for developers and improve project bankability. Feedstock support is equally important, because SAF production depends on a reliable stream of agricultural residues, used cooking oil, non-edible oils or other biomass inputs. Without assured access to such inputs, even technically viable projects can struggle to operate at scale.
The policy debate is also being shaped by India's broader fiscal constraints. Any support package will need to balance industrial policy objectives with the government's reluctance to commit open-ended subsidies. That makes the design of the scheme critical. Officials are likely to prefer a calibrated model that supports a limited number of early projects, creates proof of concept and then gradually shifts the industry toward market-based expansion.
Cost Gap Challenge
For airlines, SAF is both a compliance tool and a strategic hedge. International aviation is moving toward tighter emissions standards, and carriers will increasingly need access to lower-carbon fuels to meet customer, investor and regulatory expectations. India's aviation market is expanding rapidly, which makes the long-term emissions challenge more acute. Yet the economics remain difficult: without policy support, SAF is unlikely to compete with fossil jet fuel on price in the near term.
That is why the Centre's consideration of tax and funding support matters beyond the clean-energy sector. It could influence refinery investments, agricultural supply chains and the broader industrial ecosystem needed to build a domestic SAF market. A successful framework would also help India reduce dependence on imported aviation fuels over time, while creating a new value chain around waste and biomass feedstocks.
The proposal, if finalised, would likely be seen as an early signal that New Delhi is willing to use fiscal tools to accelerate decarbonisation in sectors where technology alone cannot close the gap. It would also align India with a growing number of economies that are using public support to seed low-carbon fuels before mandating wider adoption.
Strategic Implications
The immediate question is whether the package can be structured to attract credible private capital without locking the government into long-term subsidy exposure. Investors will be watching for clarity on eligibility, support duration, feedstock sourcing rules and the extent to which the scheme can be linked to offtake commitments from airlines or fuel distributors. The more predictable the framework, the faster developers are likely to move.
If implemented, the package could become a template for other hard-to-abate sectors where the first wave of projects needs public backing to reach scale. For now, the Centre's deliberations underscore a broader policy shift: India is increasingly looking beyond mandates and toward targeted fiscal engineering to build new clean-energy industries from the ground up.
