Integrated Scenarios
The quest for a sustainable civilization challenges us to stretch our imaginations and enrich our understanding. It invites a systemic, long-range, and multi-scale perspective for weaving together social and environmental themes, arching over decades to connect “now” with “then”, and bringing global, regional, and local realities into focus. Conventional analysis delves deeply into discrete aspects of this integrated problem but often is too fragmented for holistic assessments of the development possibilities of integrated human and environmental systems.
Tellus Institute has pioneered integrated scenario analysis by blending vision and science, the qualitative and the quantitative. We have conducted hundreds of scenario studies in partnership with stakeholders in communities, river basins, regions, and nations throughout the world. These projects bring rigorous methods to a normative task: exploring plausible futures of greater environmental stewardship and social equity, identifying strategies for redirecting development, and motivating action for sustainable futures. Scenarios, narratives and quantifications encourage collective consideration of fundamental questions: Where are we going? Where do we want to go? How do we get there?
Global Scenarios
With the Stockholm Environment Institute, the Tellus Institute convened the influential Global Scenario Group in 1995 to examine alternative futures and the requirements for a transition to sustainability, a process that continues on an expanded scale through the Institute’s Great Transition Initiative network. This path-breaking effort continues through enhancement of scenario narratives and updates of quantitative results.

The scenario quantifications utilize our PoleStar System. Where conventional projections offer only a narrow aperture on the terrain of the future, PoleStar widens the lens by including discontinuous developments and revised notions of human well-being. PoleStar invites the user to imagine alternative social visions and explore paths that lead there.
