Critically examine the claim that higher ethanol blending helps both farmers and the environment. Address the food vs fuel concern and the feedstock-dependence of emission benefits.

India reached 20% ethanol blending (E20) in Ethanol Supply Year 2025-26 [2]. The CMVR, 1989 have now been amended to allow E85/E100 flex fuel vehicles [1]. The claim that this helps both farmers and the environment is broadly true. However, the benefit depends on what crop the ethanol is made from and how it is produced.

Where the claim holds

• Farm incomes: Oil companies have paid farmers over ₹1.66 lakh crore since ESY 2014-15. The government calls this a shift from Annadata (food provider) to Urjadaata (energy provider) [2].
• More crops in the market: The National Policy on Biofuels, 2018 allowed maize and surplus grain as feedstock. This gave farmers a guaranteed new buyer [2].
• Lower emissions: The programme has avoided about 952 lakh MT of CO₂. E20 can cut lifecycle carbon emissions by up to ~40% [2].
• Energy security: Ethanol has replaced about 316 lakh MT of crude, saving over ₹1.97 lakh crore in foreign exchange [2].

Where the claim is weak

• Food vs fuel: Using maize and grain for fuel means fuel competes with food and animal feed for the same crop. This can push up prices for poorer consumers and livestock farmers [2].
• Uneven gains for farmers: Most of the benefit goes to sugarcane and maize growers in areas with distilleries. Rainfed and small farmers gain less.
• Water stress: Sugarcane uses a lot of water, so more ethanol from cane puts more pressure on groundwater [2].
• Emission gains depend on feedstock: Ethanol cuts exhaust and lifecycle emissions only when made from suitable feedstock and processes and used in vehicles designed for it [1].
• Cost: At about USD 70/bbl crude oil, E20 costs as much as petrol or more [2]. Without subsidies, farmer payouts depend on fiscal support.

Higher blending does help farmers and the climate, but only under certain conditions. The way forward is:

• shift to a mix of feedstocks, including surplus grain and crop residue;
• link procurement prices to lifecycle emissions;
• keep FFV use voluntary and properly certified [1].

This approach fits SDG 7 and SDG 13. It also keeps both Annadata and Urjadaata roles secure.
