Carbon Credit Ratings and Market Integrity: A Conversation on the Calyx Global Case

Carbon Credit Ratings and Market Integrity: A Conversation on the Calyx Global Case

Author: Harvard Business School Business & Environment Initiative April 9, 2025 Duration: 41:21
In this bonus episode of Climate Rising, we share an episode from Harvard Business School’s Cold Call podcast, featuring HBS professor Mike Toffel and Duncan van Bergen, Co-Founder of Calyx Global. The discussion focuses on Mike’s recent HBS case study, Calyx Global: Rating Carbon Credits, which explores how the company is helping improve transparency and credibility in the voluntary carbon market. Mike and Duncan join host Brian Kenny to unpack how Calyx Global evaluates carbon credit quality, how the company maintains independence in a space vulnerable to conflicts of interest, and how data and technology—from satellite sensing to AI—are transforming how carbon credits are verified and rated. The conversation also highlights key themes in the voluntary carbon market, including the tension between financial models and credibility, the challenges of measuring impact, and the broader implications for corporate climate action.

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.
