The difference between the production costs for ethanol and the gasoline prices are estimated at 4% for Brazil, 30% for both India and Indonesia, 40% for the United States and 50% for the EU. The production costs of biodiesel are almost 50% higher than fossil diesel prices in most countries. The simulated biofuel mandates are quantitative measures, but correspond to an equivalent subsidy to biofuel use that allows filling the mandate. A 1% reduction in this subsidy equivalent was also simulated.
