Changing how organizations buy goods and services can often be very challenging because of the number of stakeholders and complexities involved. New research that brings together the insights of CEOs of global companies, ecologists, sustainability professionals, and other change makers working within complex environments has revealed a tried-and-true process for leading change that sidesteps friction, super-charges buy-in, and scales-up innovative solutions, fast. In this keynote address, Leith Sharp will show how lasting change actually happens and share keys that sustainable purchasing champions can use to lead change successfully. Given the large number of deep changes that will need to be made in our organizations, business models, and economies in order to achieve the global Sustainable Development Goals by 2030, this session will prepare the audience to be effective leaders in the exciting transformation work of the next ten years. Audience members wishing to immediately apply Leith‘s insights to their work can do so during Leith‘s Hands-on Learning Workshop session later in the day.
