Confusing C Label To Go?

It would appear that Tesco is backing away from carbon labelling its products. I can't say I'm surprised. At the time of its launch (I think the first product to be labelled was a bag of crisps) many of us said the label was confusing and would not help the average consumer in his/her choice making. A Carbon Trust spokesperson expressed regret that Tesco is dropping the label but did trumpet the fact that the label is now used on £3bn worth of goods (presumably that is per year - the article didn't say - more sloppy journalism). When put alongside a €120bn loan to Greece does that really amount to a hill of beans? Frankly I think a better bet might be to provide every household with a copy of "How Bad Are Bananas?" by Mike Berners-Lee. At least that way a few people would pick up the principles of carbon footprinting rather than being faced with an inexplicable label.
