Inclusiveness, equality and equity are not just issues for developing countries. Though different groups are left behind in different contexts, the presence of these groups and individuals is universal and constant. Reducing these domestic disparities must be elevated as a priority.

Leaving no one behind lies at the heart of the United Nation's 2030 Agenda for Sustainable Development. This principle, supported by the Interdisciplinary Graduate Program in Sustainable Development, is a recurrent theme in its Together 2030 document.
