The conference theme this year is The World in 2050: Looking Ahead for Sustainable Development. “This year’s International Conference on Sustainable Development will be the most important and historic yet,” said SDSN Director and Columbia University Professor Jeffrey Sachs. “Not only will the science and policy be at the cutting edge, but ICSD will host students from around the world, top scientists, and world leaders from politics to government to the UN. I urge everybody interested in sustainable development – the great challenge of our age – to come to ICSD.” The ICSD brings together governments, academia, the United Nations and other international agencies, and NGOs and grassroots organizers to share practical solutions for the SDGs. Over 1,000 participants from over 60 countries will attend, with an additional 2,000 people joining the live stream and engaging in real-time through Twitter.
