The International Institute for Sustainable Development (IISD) is an award-winning think tank championing sustainable solutions to the world's most pressing problems. Our mission is to promote human development and environmental sustainability.

Established in 1990, IISD has offices in Canada and Switzerland, and our work impacts economies, communities, ecosystems, and lives in over 100 countries.

Our global reach allows us to bring networks together to build skills, share ideas and deliver results that last. We work at all levels, from intergovernmental forums to regional and local governments, to civil society and the private sector.

As an independent think tank, we cut through political divisions to build broad-based coalitions and offer a voice of reason in an increasingly polarized world.
