UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

Although no strong differences were found for carbon dioxide (CO 2 ) emissions, E15 showed lifecycle greenhouse gas (GHG) emissions savings when compared to E10. —RFA President and CEO Geoff Cooper California is one of only two states that has not yet approved E15; Montana is the other. Durbin, Kent C. 2023.128836.

California ARB issues feedstock-only pathway for camelina-based fuels under LCFS; zero ILUC emissions results in very low CI fuels

Green Car Congress

As a comparison, ARB’s general pathway for soybean-based biodiesel finds a direct GHG contribution of 21.25 By contrast, ARB has determined that the greenhouse gas emissions from ILUC for the camelina pathway are zero. Camelina is primarily grown in Montana, eastern Washington, the Dakotas, and Alberta, Canada. gCO 2 e/MJ.

State Department releases final environmental impact statement on Keystone XL Pipeline Project; analysis of GHG emissions

Green Car Congress

Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands using different production processes relative to gasoline produced from reference crudes. This range is equivalent to annual greenhouse gas emissions from the combustion of fuels in 588,000 to 4,061,000 passenger vehicles.
