The Environmental Protection Agency (EPA) is considering equating biogenic carbon emissions with fossil fuel emissions under the Tailoring Rule, which requires the accounting and reporting of greenhouse gas emissions under the Renewable Fuels Standard (RFS2). Biogenic carbon emissions are those that are naturally created during the combustion and decay of woody biomass and up until now, have always been considered carbon neutral by the EPA. As such, the Renewable Fuels Association (RFA) is disputing this clause in the rule.
In a letter to the EPA, RFA wrote, “While RFA generally supports a national policy to address climate change, we believe biogenic emissions must be exempt from GHG accounting schemes and regulatory frameworks. Specifically, inclusion of biogenic GHG emissions in determinations of applicability of the Prevention of Significant Deterioration (“PSD”) or Title V Permitting Programs is not scientifically justified, runs afoul of accepted national and international GHG accounting methods, and is contrary to public policies enacted to encourage development of a robust renewable fuels industry in the United States.”
According the the RFA, it is “indisputable that CO2 emissions resulting from the combustion, fermentation, and decay of biomass, are by nature, carbon neutral in that those emissions are naturally offset when the biomass removes an equivalent amount of CO2 from the atmosphere via photosynthesis during growth.”
Therefore, RFA is calling for the EPA to reconfirm that the carbon neutrality convention for accounting of biogenic GHG emissions is both scientifically justified and appropriate for regulatory contexts.Read More



“This analysis provides conclusive evidence for the EPA that there is no reason to limit the availability of E15 to newer vehicles only,” said RFA president and CEO Bob Dinneen. “This analysis together with affirmative results in reports from the Department of Energy and other academic and private testing institutions show that there are no significant issues with the use of E15 in virtually all vehicles on the road today.”
