Increased greenhouse gas emissions equal to 4.4 million additional cars on US roads are likely as a result of EPA inaction on finalizing the 2014 Renewable Fuel Standard (RFS) rules, according to a new white paper issued by The Biotechnology Industry Organization (BIO). The white paper updates earlier BIO’s March 2014 study, “Estimating Greenhouse Gas Emissions from Proposed Changes to the Renewable Fuel Standard Through 2022.”That study demonstrated that if EPA reduced biofuel use under the RFS, as the agency proposed in November 2013, the United States would experience an increase in greenhouse gas emissions and forego an achievable decrease in emissions.
