A spokesman for The Food Ethics Council suggests: "Carbon labelling prompts participating businesses to clean up their act - nobody wants a sticker with a bad mark on their product."
The Carbon Trust has announced some £2 billion worth of goods bearing the stamp are now sold in the UK annually.
Indeed, such is the mark's prominence, nine-out-of-ten households have at some point bought an item bearing the logo.
Although stricter rules will be needed to enforce a low-emissions society, the expert adds the scheme has at least made a start on reducing business energy consumption.
He also says consumers remain unaffected by the label's presence - perhaps indicating the pressure on firms to adhere is not as high as it could be.
