India's E20 ethanol blending program: Government rebuts misinformation on water use, engine damage, and emissions benefits

The Indian government issued a 10-point clarification defending its E20 ethanol blending program, which achieved 20 percent ethanol in petrol by December 2025 ahead of schedule. The Ministry of Petroleum and Natural Gas rejected claims that ethanol production wastes water, damages engines, or harms the environment, citing scientific studies and international precedent from countries like Brazil and the US. The government stated that ethanol distilleries use 3-5 litres of processed water per litre of ethanol and increasingly operate Zero Liquid Discharge systems, while maize now accounts for over 40 percent of ethanol supply with lower irrigation needs than paddy. On emissions and economic impact, the government reported that the program has saved over Rs 1.9 lakh crore in foreign exchange, paid farmers more than Rs 1.6 lakh crore, reduced CO2 emissions by about 930 lakh metric tonnes, and displaced over 310 lakh metric tonnes of crude oil imports since 2014-15. India reached its 20 percent ethanol blending target in December 2025, ahead of schedule. The rebuttal addresses specific claims about water consumption, engine compatibility, and environmental harm, citing ARAI trials and international adoption in the US, Brazil, and Europe.
