On March 7, 2016, the U.S. Environmental Protection Agency (EPA) announced the update of three greenhouse gas (GHG) inventory guidance documents. The documents have new emission factors and guidance on data estimation methods, with specific sections on waste and biomass derived fuels. The updated guidance documents are needed by organizations that must report GHG emissions to EPA and cover direct emissions from stationary combustion sources, direct emissions from mobile combustion sources, and...

EPA is inviting public comment on its analysis of greenhouse gas (GHG) emissions from the production and transport of cottonseed oil feedstock used in the production of biofuels. The Federal Register notice also provides an overview as to how EPA may apply its analysis in future determinations, as to whether biofuels from cottonseed oil will meet the criteria for renewable fuel under the Renewable Fuel Standard program. EPA notes that, based on its current analysis,...

EPA Questions Results Of DOE-Funded Study Finding GHG Emissions From Cellulosic Fuels
EPA is vigorously questioning results of a U.S. Department of Energy (DOE)-funded study that concludes ethanol produced from crop residues such as corn stover can have higher lifecycle greenhouse gas (GHG) emissions than conventional gasoline, arguing that the findings are based on an "extremely unlikely scenario" of unsubstantiated agricultural practices. RFA is also highly critical of the new study, claiming its "methodology is fundamentally flawed and its conclusions are highly...

Supreme Court To Review EPA Greenhouse Gas Program
On the first day of its new term on October 15, the U.S. Supreme Court announced that it would grant review of parts of EPA's greenhouse gas (GHG) regulations. The Court will review part of the June 2012 decision issued by the U.S. Court of Appeals for the District of Columbia Circuit, which upheld EPA's GHG program. It will review whether EPA's GHG regulations for motor vehicles should have triggered Prevention of Significant Deterioration permitting...
While in Brazil last week, U.S. Secretary of Energy Ernest Moniz stressed the importance of biofuels as part of President Obama's Climate Action Plan to reduce greenhouse gas emissions. To this end, Secretary Moniz called for greater partnership between the U.S. and Brazil on biofuels. Significantly, it was reported that Secretary Moniz stated that the U.S. Environmental Protection Agency (EPA) has the authority and ability, and will continue to consider imports when EPA sets the...
