 Professor Jeffrey Sachs, distinguished faculty, dear students, ladies and gentlemen. It is a pleasure to greet the Oath Institute at Columbia University, the Global Masters of Development Practice, the Sustainable Development Solutions Network and all others taking part in this gathering. One year ago, world leaders agreed on a plan for the future of our world, the 2030 Agenda for Sustainable Development. It aims to secure the well-being of all people and the renewal of our planet. It's a remarkable framework, comprehensive, interconnected and universal, applying to everyone and everywhere. World leaders also reached the historic Paris Agreement on Climate Change. Now we must bring these packs to life and promote positive change across the world. More than 50 governments are moving ahead, making the SDGs an integral part of development planning. But many others have a role to play in bringing about the transformation we seek, parliamentarians, businesses, investors, scientists, civil society, faith groups, the media, the creative artists, and of course, universities across the world. Implementing the SDGs calls for different ways of thinking. That is one of the strengths of the academic community. We will count on your strong engagement in fulfilling our core promise to leave no one behind. Thank you.
