Fair trade and climate change

"Tesco's announced last month that it would try to reduce air-freighted produce from 3% to 1% of its total. Much of this comes from developing countries which stand to lose billions from our new-found concern for the planet. About £7m every day, or £3bn a year, from our supermarket shop goes to developing countries - twice as much as the UK gave in debt relief last year. Most fairly traded products arrive by ship; but we shouldn't necessarily base our ethical buying choices on how goods arrive."
