- India is set to mandate a 1% Sustainable Aviation Fuel (SAF) blending requirement for international flights starting in January. - The move aims to curb carbon emissions from the fast-growing civil aviation sector and align with international climate targets. - SAF can be produced from diverse biomass and waste streams, reducing life-cycle greenhouse gas emissions compared to conventional jet fuel. - Implementation challenges include domestic production scaling, feedstock availability, and cost differentials with fossil fuels. **Introduction** India is planning to mandate a 1% Sustainable Aviation Fuel (SAF) blending for international flights beginning in January.
