... Will Reduce GHG Emissions 111% Over Gasoline

Cellulosic ethanol produced by grain ethanol producer POET’s Project LIBERTY (earlier post) first commercial cellulosic ethanol plant will reduce greenhouse gas emissions (GHG) by 111% relative to gasoline, an independent lifecycle analysis (LCA) compiled by Air Improvement Resource, Inc., has found. (I.e., the cellulosic ethanol will offset more greenhouse gas emissions than it produces.)

The reduction is somewhat less than the 130% calculated by the Environmental Protection Agency (EPA) in the RFS2 for the production of cellulosic ethanol from corn stover using a biochemical process. Air Improvement’s estimates of emissions from Project LIBERTY’s fuel and feedstock transport and fuel production (the last being the sum of storage, electricity, chemicals, waste disposal, and biogas production) are slightly higher than the corresponding elements in EPA’s analysis.
