RFA: EPA overestimates ILUC emissions
Source : domesticfuel.com
The Renewable Fuels Association (RFA) has sent another letter to the Environmental Protection Agency (EPA) regarding what they call errors in the calculations of biofuels’ carbon intensity under the Renewable Fuels Standard (RFS2). In the August 4th letter, RFA writes, "according to own analysis, EPA grossly overestimated potential emissions from land use change (LUC) attributable to the [greenhouse gas] lifecycle of corn ethanol and other biofuels". The result of correcting this error, says RFA, is that it would greatly increase the greenhouse gas reduction benefits offered by ethanol under EPA’s calculations. "Correcting this miscalculation reduces net LUC emissions (international and domestic) assigned to corn ethanol by 62% from 28.4 grams of CO2-equivalent/mega joule (g/MJ) to 10.8 g/MJ. Such a reduction in LUC emissions means overall lifecycle GHG emissions for 2022 average corn ethanol would be 38% less than baseline gasoline emissions, rather than the 21% estimate finalized by EPA."
