Biofuel stakeholder groups submitting comments on proposed rule for 2023-2026 light-duty GHG emissions standards are urging the Environmental Protection Agency to recognize the benefits of low-carbon fuels like ethanol as it seeks to lower greenhouse gas emissions.
The Renewable Fuels Association says EPA should lay out the roadmap for an orderly transition to high-octane, low-carbon liquid fuels.
“Unfortunately, EPA’s proposal fails to recognize that the fuels we put into our engines can have as much—or more—impact on fuel economy and GHG emissions as the engine technologies themselves,” RFA President and CEO Geoff Cooper wrote. “We believe the proposal missed a critical opportunity to expressly solicit public comment on potential regulatory pathways for adopting high-octane, low-carbon liquid fuels as a means of improving fuel economy and reducing emissions from the light-duty vehicle fleet.”
American Coalition for Ethanol (ACE) CEO Brian Jennings says “ethanol can and should be an even bigger part of the solution to climate change, but this depends upon the Administration’s willingness to engage us on ethanol’s role as a low carbon fuel through policies such as the Renewable Fuel Standard and the topic of this request for comments; how to reduce GHG emissions from future vehicles.”
Both organizations recommend a higher minimum-octane gasoline (98-100 RON) for all new internal combustion vehicles and updating EPA’s Lifecycle Analysis of Corn Ethanol GHG Emissions, as well as allowing GHG emissions credit generation for all alternative fuel vehicles, including flexible fuel vehicles (FFVs).
EPA is expected to finalize revised vehicle standards later this year or early next year.
