Unilever's global director of marketing discussed using corporate and product brand messaging to drive sustainable brand value. The company's Unilever Sustainable Living Plan aims to improve health and well-being, reduce environmental impact, and enhance livelihoods by 2020. While product brands play a critical role, Unilever recognizes it cannot achieve its ambitious sustainability goals through product brands alone and must also leverage its corporate brand across channels to connect with consumers and employees on its overarching purpose.
