The Role of Food Crops as Transportation Fuel

Concerns about the use of food crops such as corn and soybeans to make “biofuels” have been growing due to the sharp increase in both food and fuel prices, along with recent studies that suggest the production of these fuels may increase global warming pollution. Based on current evidence, the Union of Concerned Scientists (UCS) supports moving away from corn- and soy-based fuels towards biofuels made from waste or other resources that can be obtained in a more responsible and sustainable manner. These “better” biofuels hold significant promise and, in combination with other sustainable low-carbon fuels (e.g., renewable electricity, hydrogen), must be given effective government support if we are to reduce global warming pollution from all economic sectors, including transportation.
