A press release by Growth Energy highlights a new study that shows greenhouse gas emissions of gasoline from foreign oil are at least twice what was previously thought when the indirect greenhouse gas (GHG) emissions related to military operations in the Middle East are taken into account. The study is published in “Biofuels, Bioproducts & Biorefining”.

The study comes as indirect GHG emissions has been made a major issue by the California Air Resources Board (ARB) as it prepares to approve regulations for its Low Carbon Fuel Standard. In a CARB staff report submitted to the board for adoption, biofuels are the only fuel that has indirect effects included in their carbon accounting. Despite this new study, no indirect effects are included for petroleum-based fuels. Critics of California’s regulations have argued that applying an indirect penalty to biofuels is unfair as it sets different standards for determining a fuel’s carbon intensity. California currently imports more than 45 percent of its oil from foreign sources.

“This research is the latest example of significant indirect sources of greenhouse gas emissions that the ARB has either overlooked or ignored. It is incomprehensible that ARB staff would suggest penalizing biofuels for indirect effects, when it is clear gasoline – ethanol’s primary competitor – has a whole host of indirect effects that have not been accounted for,” said Tom Buis, CEO of Growth Energy. “In light of this important research, ARB has to delay the adoption of an indirect penalty for biofuels until the indirect effects of all other fuel pathways have been determined so that the Low Carbon Fuel Standard is fair and equitable.”
