India’s rapid transition to E20 petrol has triggered debate over fuel choice, vehicle compatibility, mileage, pricing, feedstock use and consumer communication. A recent discussion on Brazil’s long ethanol journey highlights why India can learn from Brazil’s gradual, consumer-choice-based biofuel model while strengthening its own Ethanol Blended Petrol Programme. Brazil’s first ethanol blending law dates to 1931, while India’s E20 push accelerated after the National Policy on Biofuels target was advanced to ESY 2025–26.
