Tesco shoppers will soon be able to see exactly how far their food traveled to get to their plate, and how much carbon was emitted to get it there.The UK chain (similar to Walmart) is trial-running the program, slapping "seed to store" information on everything from orange juice to lightbulbs. In the meantime, the chain will continue to research information on other products, while tackling challenges like determining exactly, say, how many greenhouse gas emissions biofuels have.
Will Tesco's program be met with cheers or jeers? Will customers even notice - or care? Only time will tell, but I continue to be wary of large chains making big environmental claims. Ironically, if the program were truly successful, people would have to stop shopping at chain stores and grow their own food or buy at farmer's markets or local organic co-ops, which is exactly, of course, what Tesco doesn't want.
