Sugarcane production in Brazil has expanded, and about half is used for ethanol
The Government of Brazil has supported the production of ethanol as an automotive fuel for many years, beginning in 1975 with the Proálcool program, to encourage production of ethanol from sugarcane and including many programs that remain in effect today—including mandatory ethanol-blending requirements in gasoline and tax exemptions for ethanol-powered cars. Sugarcane is nearly the exclusive ethanol feedstock in Brazil, and Brazil is the world’s largest sugarcane producer, accounting for 39 percent of world production. Until the mid-1990s, the share of sugar production turned into ethanol was set by government policy, but since then market forces have determined the share that is converted to ethanol. In particular, the relationship among the prices of sugar, gasoline, and ethanol, as well as storage capacity at sugar mills, all play a role. Production of both sugar and ethanol in Brazil has expanded rapidly since the mid-1990s. Sugarcane production reached 640 million tons in 2014, up 188 percent since 1991, while over the same time, the share used for ethanol production declined from 72 percent in 1991 to a low of just over 49 percent in 2003 and a 2014 level of 55 percent.
