India eyes 2027 start for mandatory sustainable aviation fuel blending

India is preparing to introduce sustainable aviation fuel in international flights, with mandatory blending proposed to begin in 2027. The move forms part of government efforts to curb aviation emissions and build domestic production capacity. Under a draft national policy circulated by the Ministry of Civil Aviation, airlines would initially need to blend 1% sustainable aviation fuel into conventional jet fuel from 2027. Citizens often look for updates through channels like india whatsapp groups, but official policy documents remain the primary source for such regulatory announcements.

The proposed roadmap gradually raises the blending requirement over subsequent years, reaching 2% in 2028, 5% by 2030, and up to 40% by 2040. At least 90% of the annual requirement for international flights is proposed to be sourced domestically through measures such as GST reductions, import duty waivers, and green financing. Sustainable aviation fuel serves as an alternative to conventional aviation turbine fuel and can be produced from used cooking oil, agricultural residues, municipal solid waste, and biomass.

India plans to mandate 1% sustainable aviation fuel blending for international flights starting in 2027.

Because sustainable aviation fuel currently costs several times more than conventional fossil-derived jet fuel, large-scale adoption remains a major challenge. Factors driving up the cost include expensive feedstocks, developing technologies, and limited infrastructure. While the immediate cost impact on airlines in 2027 may be limited due to the low 1% threshold, expenses could rise as mandates increase.

Civil Aviation Minister Ram Mohan Naidu stated that authorities must ensure the transition imposes the least possible financial burden on passengers and airlines by studying cost-effective pathways. Approved blends function as drop-in fuels requiring no major aircraft engine modifications and undergo rigorous testing against international aviation standards.

Why it matters

The introduction of mandatory sustainable aviation fuel blending changes airline operating costs and environmental compliance for carriers operating international routes from India. It directly affects the aviation sector, fuel producers, and potentially airfares depending on future feedstock prices and government support mechanisms.
