In 2014, ArcelorMittal—the world's largest steel and mining company—began a process to develop and implement what World Steel Association has called the most ambitious sustainability narrative in the steel industry. In this session, ArcelorMittal corporate responsibility leaders will detail their process of internal socialization, external stakeholder engagement and implementation of a new and innovative sustainability strategy. They asked stakeholders, "What would it mean if ArcelorMittal were the most sustainable steel company in the world?" You will learn from their lessons, triumphs and mistakes. This session will provide a framework for developing a sustainability narrative, navigating landmines in implementation, and creating an iterative process that will engage every level of your organization and your stakeholders to drive sustainability in your work. PRESENTERS: Beth Spurgeon, William C. Steers, and Marcy Twete of ArcelorMittal.
