The authors, Daniel G. De La Torre Ugarte and Burton C. English, found that the RFS not only fell short of goals for current-generation biofuels technology, it may also have failed to serve as a stepping stone to environmentally superior approaches. Dr. De La Torre Ugarte said:
“Our analysis shows that the RFS has created more problems than solutions, particularly with regard to hampering advancements in biofuels. Corn ethanol was presented as a ‘bridge’ to advanced biofuels and a means of reducing GHG emissions. However, the reality is clear that this policy has been a bridge to nowhere.”Corn-based ethanol increases global food prices by diverting an important food source to fuel. USDA data show that ethanol for fuel now uses more than 40% of all U.S. corn production.
The RFS is the topic of a new video advertisement by opponents who encourage faster progress toward more advanced biofuels technologies.
