Brazilian sugar cane ethanol provides significantly more energy than the fossil fuels required to produce it, whereas corn ethanol in the US provides only marginal energy gains. Sugar cane ethanol also reduces greenhouse gas emissions. Due to pressure from US corn growers, the US imposes tariffs on imported sugar cane ethanol to protect the domestic corn ethanol industry. Brazil has cultivated a profitable ethanol industry through government subsidies and high gasoline taxes, and nearly all fueling stations offer ethanol.
