But what is their impact on developing countries?

Tesco, the giant United Kingdom supermarket chain, sparked a furious debate about green shopping in February when they announced planned ‘carbon friendly’ measures such as restrictions on the stocking of air freighted produce and the introduction of carbon counting labelling. On the back of warmer winters, hotter summers and the shock value of Al Gore’s Oscar-winning film, An Inonvenient Truth, the issue of climate change has mainstreamed into consumer consciousness in the UK, and the Tesco announcement is a response to this awareness.
