Green Concrete: Decarbonizing Construction with Recycled Glass

Green Concrete: Decarbonizing Construction with Recycled Glass

Author: Harvard Business School Business & Environment Initiative May 8, 2024 Duration: 29:00
The first of a series on decarbonizing the roots of value chains, where we’re looking deep into supply chains that serve many industries, this episode focuses on concrete. Concrete is one of the world’s most popular materials, and it accounts for nearly 8% of the world’s greenhouse gas emissions, most of which comes from cement– the glue that binds conventional forms of concrete.  We focus on one type of green concrete produced by Urban Mining Industries that replaces half of the cement with recycled glass that makes its product much less carbon intensive. We present this story through an episode of the HBR Cold Call podcast, where host Brian Kenny interviews HBS professors Shirley Lu and Bob Kaplan. They discuss how Harvard is pilot testing the use of green concrete in its current construction projects as part of the university’s efforts to reduce its carbon footprint. They’ll also discuss various methods to measure carbon emissions, including the e-liability approach Bob Kaplan lays out in a recent Harvard Business Review article.

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.
