Microsoft ’s Climate Strategy and Its Carbon Removal Deal with Chestnut Carbon

Author: Harvard Business School Business & Environment Initiative September 10, 2025 Duration: 44:34
Microsoft’s Brian Marrs, Senior Director of Energy and Carbon Removal, and Chestnut Carbon CFO Greg Adams share their perspectives as a major buyer and developer of carbon removal credits. Their 2025 deal is one of the largest carbon removal deals in the U.S. and seeks to deliver 7 million tons of nature-based carbon credits over 25 years.  Brian explains Microsoft’s carbon negative strategy and targets, and the role of carbon removal credits. He also describes how Microsoft is using its Climate Innovation Fund and procurement efforts to “build missing markets” in decarbonized energy, materials, and transportation.  Greg describes how Chestnut Carbon combines afforestation, land ownership, and a private equity-backed project development model to deliver high-integrity carbon credits. He explains how their work is similar to long-term energy infrastructure contracts like power purchase agreements (PPAs), and how they are using proprietary tools to scale.   Brian and Greg also share their advice for those looking to learn more and work in the field.  

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.
