IBM’s Chief Sustainability Officer on AI, Efficiency, and the Future of Sustainable Business

IBM’s Chief Sustainability Officer on AI, Efficiency, and the Future of Sustainable Business

Author: Harvard Business School Business & Environment Initiative June 10, 2026 Duration: 35:04
Artificial intelligence is reshaping how businesses operate — but it is also reshaping how companies think about sustainability. Christina Shim, Chief Sustainability Officer at IBM, joins Climate Rising to discuss how AI, cloud infrastructure, and emerging technologies like quantum computing are transforming corporate sustainability strategies. Drawing on her background across consulting, government, investing, startups, and technology, Christina explains how IBM is redefining sustainability from a compliance function into a core business capability. The conversation explores the “efficiency stack” of AI — from chips and data centers to software models and enterprise applications — and how improvements in efficiency can reduce costs, emissions, and operational waste. Christina also shares examples of how IBM and its partners are applying AI to urban heat islands, sustainable materials discovery, infrastructure maintenance, and enterprise sustainability management. The episode also examines the tension between AI’s growing energy demand and its efficiency gains, the role of “fit-for-purpose” models, and why Christina believes the social and governance implications of AI deserve even more attention than the environmental ones.

Hosted by the Harvard Business School Business & Environment Initiative, Climate Rising moves beyond abstract warnings to examine the concrete realities facing companies today. Each episode features candid conversations with senior executives, policymakers, and HBS faculty, dissecting the operational and strategic choices that define a business's relationship to a warming planet. You’ll hear how leaders are navigating pressures from investors, customers, and regulators while making pivotal decisions on everything from supply chain logistics and new technology investments to long-term risk assessment and competitive positioning. This isn't a theoretical discussion; it's a ground-level look at the practical dilemmas and innovations shaping industries. The podcast delves into the nuanced trade-offs managers face, turning climate change from a looming threat into a series of actionable, if complex, business problems. For anyone curious about how the private sector is actually responding-the successes, the stalled efforts, and the evolving playbooks-this series offers an essential and sobering dialogue. Tune in for a direct line to the thinking that is quietly redrawing the corporate map.
