 Another benefit of bioethanol is the reduction of greenhouse gas emissions as compared to gasoline, because as much carbon dioxide is taken up by the growing plants as is produced when the bioethanol is burnt, with a zero theoretical net contribution. Several studies have shown that sugarcane-based ethanol reduces greenhouse gases by 86 to 90 % if there is no significant land use change, and ethanol from sugarcane is regarded the most efficient biofuel currently under commercial production in terms of GHG emission reduction.
