I appreciate the question and the premise about the myth, because that's exactly what it is, a myth.
The International Energy Agency released a report within the last month, which is the most up-to-date life-cycle assessment evaluation of renewable fuels, and they looked back over the last 20 years of renewable fuels development, so data back in the 1980s, 1990s, and also in fact projecting forward into 2015. So the number that I make reference to, the 55% reduction of greenhouse gas by blending a litre of ethanol as compared to fossil fuel, is the most accurate life-cycle assessment data we have that demonstrates the greenhouse gas benefits that are derived by ethanol.
