[Ed. – How about if you cut off the crusts?]
First we were warned about beef, which comes from cattle, which in turn produce not only steaks but farts, which result in increased greenhouse gas emissions.
But now comes word that that lunchtime staple, the lowly sandwich, is also a culprit in the battle to curb global warming:
In the first study of its kind … researchers [at the University of Manchester] carried out an in-depth audit of various sandwiches throughout their life cycles and found the triangular meals could be responsible for the equivalent annual carbon emissions of 8.6 million cars in Britain alone.
What the researchers found was that not all sandwiches are created equal and that some varieties have larger carbon footprints than others. The highest footprint was found in premade, prepackaged, all-day-breakfast sandwiches. These contain eggs, bacon, and sausage and are kept packaged and refrigerated until sold and eaten — all of which is estimated to add up to 1,441 g (3.18 lb) of carbon dioxide equivalent, or roughly the same as driving a car for 12 miles (19 km).
