(NAFB.com) – Growth Energy submitted comments to the California Air Resources Board criticizing the latest updates to California’s Low Carbon Fuel Standard. Growth Energy says the changes unfairly single out American biofuels and make it hard for them to generate credits under the program. Specifically, Growth Energy objected to a proposed “sustainability certification” requirement, calling it “a double penalty for corn starch bioethanol.” Senior Vice President of Government Affairs Chris Bliley says the economic impact analysis acknowledges potential direct and indirect land use change is at least partially and potentially fully accounted for by the LUC scores added to crop-derived pathways. “This acknowledgment renders the need for a sustainability certification moot as potential LUC concerns for crop-based feedstocks are addressed,” he said. Farmers that produce feedstocks for biofuel production are required to use climate-smart practices to qualify for certification but still wouldn’t get any credit for the emissions reductions under the LCFS.
