Sustainability is entering a new phase. As data volumes grow and expectations rise, leaders are under pressure to move beyond reporting and compliance toward real operational impact and innovation. In this keynote, Hilary Tam explores how cloud and AI are reshaping sustainability leadership — enabling organisations to turn sustainability data into decisions, optimise operations at scale, and unlock new sources of value. Drawing on practical experience from AWS and its customers, she will share a future-fit approach to sustainability that connects impact with growth, innovation and long-term competitiveness. Looking ahead, Hilary will examine how AI and emerging agentic systems are changing what sustainability teams can do — and the leadership choices this creates. As sustainability moves from obligation to opportunity, this session challenges leaders to rethink not just how they deliver net zero, but how sustainability creates value in their organisations.
