Guy Farrant, Director of Food, Marks & Spencer said 'our customers want to know more about how food is transported into the UK. We already label all our food with its country of origin, and in many cases we also include the name of the farmer on pack. We’re putting an aeroplane symbol on the small amount of food we transport by air because we know this is something our customers increasingly care about.' ::New Consumer
Meanwhile, the Carbon Trust is offering labels that show how much carbon was emitted in the manufacture and transport of the goods.
Euan Murray, the Carbon Trust's head of strategy, said the scheme was the culmination of two years' work with a number of companies.
"We quickly realised how valuable this sort of information was," he told BBC News. "We built up a profile, which has become known as the carbon footprint, of different products."
Mr Murray said the label would show how many grammes of carbon dioxide (CO2) had been emitted during the various stages of production, from the sourcing of raw materials, the manufacturing processes, to transporting the products to stores. ::BBC
