100% ethanol blending target aims to replace fossil fuels entirely with ethanol in petrol
GK and monthly revision
What is 100% ethanol blending? | Explained
The article explains 100% ethanol blending as a policy goal to reduce fossil fuel dependence and emissions. It highlights that achieving this target sustainably requires scaling up second-generation (2G) ethanol from agricultural residues, avoiding over-reliance on sugarcane-based first-generation ethanol. This is critical for India's energy security, net-zero commitments, and Sustainable Aviation Fuel (SAF) production. For exams, it links to National Biofuel Policy, Ethanol Blended Petrol Programme, and climate action under UNFCCC.

Key points
Exam-ready takeaways
First-generation ethanol from sugarcane molasses cannot sustainably meet 100% blending without stressing water and land resources
Second-generation (2G) ethanol from agricultural residues (rice straw, wheat straw, bagasse) is essential for scalable, sustainable supply
Sustainable Aviation Fuel (SAF) production requires 2G ethanol to meet aviation decarbonisation goals under CORSIA
National Biofuel Policy 2018 targets 20% ethanol blending by 2025-26 (advanced from 2030); 100% remains long-term aspirational goal
