emissions suggest that we need to halve our energy use from 2000 to 2050.1 At the same time, to allow developing countries to 'catch up' to the developed world, we would need to allow for a doubling of demand [5,8,9]. Taken together, this would require that the energy intensity of material production in 2050 be only one-quarter of that in 2000.
