Yes. Biofuels (like ethanol from sugar cane) burn just the same as other fuels. Ethanol is a hydrocarbon containing Hydrogen, Oxygen and Carbon atoms. When combusted (with Oxygen from the atmosphere) they produce H2O, water (not pollution), but also produce Carbon Dioxide (CO2) and worse yet Carbon Monoxide (CO) (For why they produce CO and CO2, read up on incomplete combustion.). CO2 and CO are pollutants, they are greenhouse gases and contribute to global warming.
