Calculating your carbon "food" print

I thought this was really fun. The site gives you frying pan and photos of various meal options for breakfast, lunch, dinner and any time. You click and drag your choice into the pan, and its carbon food points appear in the right hand column calculating you daily carbon total the way you would calories. A high carbon diet is apparently 4500 points which if eaten every day would release the equivalent of 3 tons of CO2 a year. To make a positive difference, the site advises keeping to 2500 points or lower a day.
