Great Transition: The Promise and Lure of the Times Ahead

Paul Raskin, Tariq Banuri, Gilberto Gallopín, Al Hammond, Rob Swart, Robert Kates, Pablo Gutman

The planetary phase of history has begun, but the future shape of global society remains profoundly uncertain. Though perhaps improbable, a shift toward a planetary civilization of enriched lives, human solidarity, and environmental sustainability is still possible. This treatise examines the historic roots of this fateful crossroads, analyzes alternative scenarios that can emerge from contemporary forces and contradictions, and points to strategies and choices for advancing a Great Transition. It synthesizes the insights of the Global Scenario Group, convened in 1995 by the Tellus Institute and Stockholm Environment Institute to explore the requirements for a sustainable and desirable future.


Bending the Curve: Toward Global Sustainability

Paul Raskin, Gilberto Gallopín, Rob Swart, Al Hammond, Pablo Gutman

This paper analyzes the prospects for sustainability within the confines of Conventional Worlds scenarios. The shift to more sustainable forms of development must at least begin at this level, although we will likely need more fundamental social changes to complete the transition to a sustainable global society. The paper introduces social and environmental targets as well as strategic policies for reaching them. It shows both the great potential for progress and the daunting challenges within a growth-driven development paradigm.

Branch Points: Global Scenarios and Human Choice

Gilberto Gallopín, Al Hammond, Paul Raskin, Rob Swart

This paper introduces scenario methods and a framework for envisioning global futures. It depicts contrasting world development scenarios, all compatible with current patterns and trends, but with sharply different implications for the quest for sustainability in the twenty-first century. The paper focuses on three broad scenario classes—Conventional Worlds, Barbarization, and Great Transitions—which are characterized by, respectively, essential continuity with current patterns, fundamental but degenerative social change, and fundamental and progressive social transformation.
