A Green Economy, in the context of sustainable development and poverty eradication, is one of the two central themes of Rio+20. It underlines that it is in the interests of all nations - developed and developing and state or market-led - to begin reducing humanity's planetary impact in ways that reflect national circumstances. This summary report by UNEP's International Resource Panel is an important part of this overall discourse and direction. It brings empirical evidence to bear on the levels of natural resources being consumed by humanity and the likely consumption levels if past trends are mirrored into the future.
By 2050, humanity could devour an estimated 140 billion tons of minerals, ores, fossil fuels and biomass per year three times its current appetite unless the economic growth rate is decoupled from the rate of natural resource consumption.
