The article compares India's rapid ethanol policy transition with Brazil's long-term approach, highlighting key differences in strategy and challenges.

Brazil's ethanol journey began in 1931 with mandatory blending, but it took decades of technological, logistical, and regulatory development to establish a robust system.Flex-fuel vehicles became a game-changer, allowing drivers to switch between ethanol and petrol based on price and environmental considerations.India, by contrast, accelerated its ethanol blending target from 2030 to 2025-26, achieving 20% blending in petrol by 2023.However, the article raises concerns about consumer trust, as higher ethanol blends like E20 may lead to lower mileage without clear cost benefits.Experts like Horta and Gussi emphasize the need for rigorous testing and transparency to build confidence.

Brazil's experience shows that higher ethanol blends require vehicle and fuel-system adaptation, with technical tests ensuring safety before implementation.

The article underscores that while India's approach is faster, it risks overlooking the importance of thorough testing and consumer education to avoid the pitfalls faced by Brazil in its early stages.
