Spanning Boundaries: Aspen Global Change Institute Strategic Plan, 2020-2025 outlines how AGCI will build on the foundation of its first 30 years. The plan leverages AGCI’s key strengths and legacy as a convenor and collaborator, while also aligning future work with newly developing capacities that extend the Institute’s impact. In the following pages, we set forth five values, three goals, and three programs that embody AGCI’s mission and map a path to fulfilling it. In addition, we briefly describe key mechanisms for accomplishing this plan and make commitments to sustainability, broadly defined. Finally, we invite readers to join us by sharing your ideas, following our progress, offering partnership, or otherwise helping make this plan a reality.
