Tellus Institute was established in 1976 as an interdisciplinary, not-for-profit research and policy organization. Our aim was, and is, to bring scientific rigor and systemic vision to critical environmental and social issues. The time was right for a young institute bringing fresh thinking to new challenges, and we grew rapidly. Since 1976, we have conducted 3,500 projects throughout the world, becoming an internationally recognized leader in the emerging field of sustainable development.
