The UN conference on sustainable development “Rio + 20” marked the twentieth anniversary of the 1992 Earth Summit from which the first international convention to address climate change was agreed (among other international environmental commitments). There was a distinct lack of international commitment to address sustainable development. Instead it was left to unilateral initiatives to fill the vacuum.
