recognizes that ethanol will likely continue to predominate the renewable fuel pool in the near future, and that for 2014 the ability of the market to consume ethanol in higher blends such as E85 is highly constrained as a result of infrastructure- and market-related factors. EPA does not currently foresee a scenario in which the market could consume enough ethanol sold in blends greater than E10, and/or produce sufficient volumes of non-ethanol biofuels to meet the volumes of total renewable fu
On top of certifying plug-in vehicles with mpg and mpge ratings (Chevy Volt, 93 mpge; Nissan Leaf, 99) and delaying E15 decisions, the EPA is also tasked with figuring out the 2011 Renewable Fuel Standards. Today, the agency finalized the 2011 percentage standards for the four categories of fuel – cellulosic biofuel, biomass-dericed diesel, advanced biofuel and renewable fuel – that make up the agency's renewable fuel standard program, known as RFS2.
The U.S. Environmental Protection Agency (EPA) has announced what it thinks the 2011 percentage standards for the Renewable Fuel Standard program (aka RFS2) should be. The EPA proposed that the overall volumes and standards for the four fuels categories in the program should be:
