These are hard times for international cooperation. With rising protectionism, burgeoning trade disputes, and a troubling lack of concern for shared interests like climate change, the world seems to be turning its back on multilateralism. In an era when the benefits of multilateralism are being questioned precisely as we draw closer to the planet’s ecological limits, income inequality is growing, and innovation and technology are transforming how people learn and work, the world needs a more equitable and cooperative approach to globalization. And one of the best ways to deliver it is with a sustainable development model that leaves no one behind. By Alicia Bárcena Ibarra, Stefano Manservisi, and Mario Pezzini.
