Leadership Lab (L-Lab) L-Lab tackles the critical issues of global business sustainability. The course combines an overarching way to think about systemic change, an on-site field project experience with leading-edge sustainability initiatives, and personal work in individual leadership capacities. It provides the opportunity to influence complex global sustainability efforts that require both new ways of sensemaking and new ways of collaborating across boundaries. Field projects include major organizations at the forefront of today’s thinking about systemic change and sustainable systems, located locally, nationally, and internationally. Previous years’ classes included projects with such organizations as Nike, Starbucks, BP India, PepsiCo, Oxfam, WWF, and the Cambridge Energy Alliance.
