Current Context : India and the United States have agreed to promote sustainable aviation fuel (SAF), electrification of medium and heavy-duty vehicles, and the use of hydrogen in buses, tractors, and heavy equipment.

About Sustainable Aviation Fuel (SAF) :

It is an eco-friendly alternative to conventional jet fuel, aimed at reducing carbon emissions in aviation.

Benefits:

1. Lower Carbon Emissions: SAF can cut greenhouse gas emissions by up to 80%over its lifecycle.
2. Feedstock: Derived from renewable sources like biomass, used cooking oil, and municipal waste.
3. Compatibility: SAF can be blended with traditional jet fuel and used without engine modifications.
4. Challenges: Currently more expensive and limited in production compared to conventional fuels.
5. Global Impact: Crucial for meeting aviation emission reduction targetsunder CORSIA (ICAO).
