Changes to the Renewable Fuel Standard program were proposed by EPA in response to directives from Congress—if adopted, the rules will require that a higher percentage of transportation fuel sold in the United States be derived from renewable sources, such as corn‐based ethanol or biomass‐based diesel.
Policy Integrity submitted public comments defending EPA’s decision to count the international impacts of the emissions from these new fuels. Failing to account for the indirect effects of certain renewable fuels would lead to ineffective standards—accepting fuels that did not genuinely meet the minimum requirements.
