The future we want: Green growth or sustainable development?

Green growth was a key theme of 2012's Rio+20 conference. There is, however, confusion about what should be sustained: Is it all encompassing development? Is it economic growth, greened or otherwise? Or is it human well-being? This commentary compares these concepts within a framework of sustainability categories. The reality test of measurability points to green growth rather than all-inclusive wealth, welfare or holistic development.
