Bucknell University's fourth annual Sustainability Symposium took place during the week of April 4-8, 2016.

Nearly 30 years after the publication of "Our Common Future," the Brundtland Report from the United Nations World Commission on Environment and Development, the concept of sustainability — and the related idea "sustainable development" — continue to guide deliberations and actions surrounding economic, social and environmental interactions globally.

Discussions of "planetary boundaries,"  "the Anthropocene," the UN's Sustainable Development Goals, and the 2015 UN Climate Change Conference offer current examples of global-scale processes aimed at identifying a "safe and just operating space for humanity."

Despite a spectrum of ongoing efforts, significant questions remain concerning the diverse ways in which sustainability has been defined and translated into practice, and they have produced important lines of debate regarding the term's ability to orient global affairs.

The 2016 Bucknell University Sustainability Symposium critically examined the trajectory of sustainability as a global phenomenon.
