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. They have worked at all geographic levels—global, regional, national, local, and enterprise—bringing an integrated perspective to bear on environmental, social, and economic questions. Key thematic foci have included energy, water, sustainable communities, corporate responsibility, and climate change, with projects often featuring the development of alternative scenarios of the future. At Tellus, They are now embarked on a new phase, reframing our programs around the larger mission of advancing a just and sustainable planetary civilization. This Great Transition would entail a fundamental shift in human values and in the ways They produce, consume, and live. The key is balancing the rights of all people now alive with those of future generations and the wider community of life. Realizing this depends on generating viable, attainable visions of another world, cultivating a sense of global citizenship, and engaging in collective action for systemic change. These are the aims that animate the research, outreach, and network-building efforts of the Tellus Institute.
