Harmonizing Low Carbon Fuel Standards

Green Car Congress

Harmonizing fuel programs between state, federal, and foreign jurisdictions is useful to ensure the optimum reduction of greenhouse gas (GHG) emissions. —Low Carbon Fuel Standard 2011 Program Review Report. Earlier post.). Earlier post.). Northeast States, Oregon, the EU, etc.).

Study finds renewable fuel mandates alone not likely to lower carbon intensity of biofuels; the importance of localized LCAs and optimized low carbon fuel standards

Green Car Congress

Ultimately, the authors suggest, states can encourage the reduction of fuel GHG emissions by developing policies, such as a low carbon fuel standard (LCFS), that encourage incremental improvements in corn ethanol in the short term and in the medium term by switching to cellulosic-derived fuels. renewable fuel standards—and LCFSs.

Gevo options SD site for expansion project; 45M gallons per year renewable jet fuel and gasoline

Green Car Congress

Lake Preston is in eastern South Dakota, about 105 miles from the facility in Luverne, Minnesota. Gevo’s products perform as well or better than traditional fossil-based fuels in infrastructure and engines, but with substantially reduced greenhouse gas emissions.

ARB: carbon intensity of biomethane from wastewater sludge could be as low as -65.27 g CO2e/MJ

Green Car Congress

Staff estimated the carbon intensities (CIs) for biomethane produced under two alternative scenarios; under the first scenario, the CI of biomethane is 10.86 In this model, the majority of the biogas is allocated to the production of renewable power using a device such as a gas-fired turbine with an exhaust heat recovery system.

Researchers say fuel market rebound effect can result in increased GHG emissions under RFS2; suggest taxes over mandates

Green Car Congress

The US Renewable Fuel Standard (RFS2) is intended to reduce greenhouse gas emissions from transportation. Increasing the supply of low-carbon alternative fuels is a basic strategy to reduce greenhouse gas emissions. The Minnesota team, which found that a majority of the estimates fell below 0.50 for its analysis.

Gevo enters into long-term supply agreement for renewable isooctane with HCS Group: worth up to $180M

Green Car Congress

Gevo’s renewable isooctane is a low-carbon, drop-in blending component for gasoline and has the potential to reduce greenhouse gases by as much as 70%, well within the standards established by the EU Renewable Energy Directive.
