Food miles – how far an item has travelled from the producer to the retailer – became a contentious subject in the early 2000s. The distance travelled was treated as an indicator of the amount of energy used and carbon generated. New Zealand producers providing food to the European market were at first concerned about the effect such an assessment would have on consumers' response. But research showed that food miles were not an effective measure. The Carbon Trust (which is mentioned in this television news item) was a British scheme which tracked the carbon generated in getting a product from grower to supermarket.
