This document outlines plans for the BYND 2015 Summit, which will gather 500 young leaders to develop solutions for issues facing youth and contribute to the UN Post-2015 development agenda. Through an interactive workshop format and extensive use of ICT, the Summit aims to have a global reach beyond the event walls. UN agencies will partner on thematic tracks linked to crowdsourced challenges on topics like entrepreneurship, education, and youth participation. The outputs will be presented to the UN General Assembly in September.
