GENEVA – At the upcoming Rio+20 summit in Brazil, more than 135 heads of state and government, and up to 50,000 participants, including business executives and civil-society representatives, will come together to express their collective commitment to advance inclusive, sustainable development. But, despite the goal of unity and collective action underpinning the summit, the best way forward for the global economy is to build on the actions that individual countries and regions are taking in pursuit of their own interests.
