Sugar production is promoted by government support schemes such as the US sugar programme and, through the increased interest in sugar-based ethanol, is also affected by biofuel policies. The future of biofuel production and the associated feedstock is hence greatly determined by how the main producers of biofuels will design their policies. The uncertainty that currently surrounds these policies, especially in the European Union and United States (see also Biofuel Chapter), implies that policy changes could completely change the production outlook for these commodities.
