UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

Total hydrocarbons (THC), non-methane hydrocarbons (NMHC), and carbon monoxide (CO) showed either marginally or statistically significant reductions for E15. Although no strong differences were found for carbon dioxide (CO 2 ) emissions, E15 showed lifecycle greenhouse gas (GHG) emissions savings when compared to E10.

Proposed CA LCFS pathways for corn starch ethanol with carbon capture and sequestration: as low as 37 gCO2e/MJ

Green Car Congress

North Dakota-based Red Trail Energy (RTE), which since 2007 has operated an ethanol production facility with annual production of about 60 million gallons per year, is proposing sequestration of CO 2 produced from starch fermentation to lower the overall carbon intensity of the fuel for the California Low Carbon Fuel Standard (LCFS).

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

Green Car Congress

a wholly owned subsidiary of Global Clean Energy Holdings, a feedstock-only pathway for the production of camelina-based fuels under the Low Carbon Fuel Standard (LCFS). The feedstock-only CI (carbon intensity) is 7.58 As a comparison, ARB’s general pathway for soybean-based biodiesel finds a direct GHG contribution of 21.25

State Department issues Draft Supplemental Environmental Impact Statement on Keystone XL Pipeline: climate change impacts

Green Car Congress

Comparison of proposed Keystone XL route to previously proposed project segment. Greenhouse gas LCA analysis. The DOS team compared life-cycle greenhouse gas emissions of petroleum products from WCSB oil sands crudes with reference crudes, using a number of life-cycle analysis (LCA) studies as input.

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.
