Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light.

California ARB considering amendments to Low Carbon Fuel Standard; handling high carbon-intensity crude oil (HCICO)

Green Car Congress

The California Air Resources Board (ARB) will consider at its December 2011 meeting amendments to the Low Carbon Fuel Standard (LCFS) regulation. The LCFS intends to reduce, on a full-fuel lifecycle basis, the carbon intensity (CI) of transportation fuels (measured in gCO 2 e/MJ) used in California by an average of 10% by the year 2020.
