In this bonus episode, sustainable footwear brand Allbirds co-founder and co-CEO Joey Zwillinger, Prof. Michael Toffel, and Cold Call host Brian Kenny discuss the growing environmental impact of the fashion industry, and how Allbirds is balancing a critical tension between sharing its know-how and material innovations with competitors to scale its efforts to decarbonize fashion, while also retaining brand differentiation. This was originally broadcast on the HBS Cold Call podcast episode profiling the HBS case, “Allbirds: Decarbonizing Fashion,” which Prof. Toffel wrote with Ken Pucker and Eren Kuzucu.
