In 2017, the Association for the Advancement of Sustainability in Higher Education (AASHE) and Root Solutions, with funding from the Lisa and Douglas Goldman Fund, created the "Turning the Page on Campus Paper Use" initiative to assist higher education institutions in developing and implementing paper reduction behavior change projects. "Turning the Page: A Behavior Change Toolkit for Reducing Paper Use" draws upon real world experiences from the Turning the Page initiative as well as other paper reduction campaigns. The concepts, concrete examples, and tools in this guide will empower practitioners to more effectively target paper consumption behaviors at their institutions. Although this guide focuses on tackling paper reduction efforts at higher education institutions, the advice and examples provided can be applied by any organization looking to foster more sustainable behaviors. The hope is that this guide gives the reader the background, inspiration, and confidence to ideate and implement the kinds of evidence-based behavior campaigns that can result in transformational impact at their organization.
