Vegan/local/organic diet response...what???

"Your 2009 food emissions are projected to be 3.7 tons CO2. That's 13% more than average. No worries, we can help you reduce it through conservation and offsetting."

Eh hem: My 100% vegan and 80%local and 90% organic diet is stated here to be 13% higher than average? I don't think so.
