The International Institute for Sustainable Development (IISD) is an independent think tank championing sustainable solutions to 21st century problems. Our mission is to promote human development and environmental sustainability.Our big-picture view allows us to address the root causes of some of the greatest challenges facing our planet today—ecological destruction, social exclusion, unfair laws and economic rules, a changing climate. Through research, analysis and knowledge sharing, we identify and champion sustainable solutions that make a difference. We report on international negotiations, conduct rigorous research, and engage citizens, businesses and policy-makers on the shared goal of developing sustainably.
