Energy sustainability "requires huge population cut"

Combatting global warming will require a massive two-thirds cut in the world's human population as well as cleaner technologies, a British NGO has claimed. The Optimum population trust bases its assertion on ecological footprinting techniques championed by groups like WWF (ED 14/06/05). Assuming people all over the world reach a European standard of living, then even with a major shift to renewable energy the earth's carbon absorption capacity would be exceeded 2.8 times, the group estimates.
