Apple Google SpotifyBusiness is full of animal metaphors: bull markets, cash cows, and fat cats abound. But for IMD alumni Severin Dressen, the natural world is a far more literal part of his day-to-day work.
As the CEO of Zurich Zoo, he’s taking a proactive role in tackling the worldwide loss of biodiversity. Since the Zoo reopened, visitors have flocked in, and Severin says that it’s his responsibility to educate others about the importance of sustainability; whether that be through elephant conservation projects in Thailand, or in Zürichberg itself.
In an interview with IMD Professor David Bach, Severin opens up about his first year in office. Highlights of this episode include details on the shifting face of conservation, how changing where we conduct our meetings can change outcomes, and what Severin thinks we can learn from the animals.
