Swiss finance and innovation hub Zurich held its first Climate Week in May 2026, joining a growing global network of cities hosting climate-focused gatherings. All Things Sustainable is the official podcast of Climate Week Zurich, and in this episode, we bring you highlights, key takeaways and a look ahead to the next big events on the climate calendar.
To learn about Zurich's approach to decarbonization and climate adaptation, we sit down with the city's Director of Environmental and Health Protection, René Estermann.
"We know climate change is a huge risk," René says. "As the major economic driver in Switzerland, Zurich wants to grow its business hubs here for climate technologies, climate science, carbon management ... [and] climate finance ... to turn these risks to opportunities."
To understand how financial institutions are responding to growing calls to make the business case for sustainability, we talk to Sabine Döbeli. Sabine is CEO of Swiss Sustainable Finance, a nonprofit whose members aim to strengthen Switzerland's position as a leading worldwide center for sustainable finance.
"If you invest today to improve your factory, to have less pollution, to use less water, to have a circular process, then that of course means capex, it means investments," Sabine says. "It will pay off in the long term if you have less costs. But to prove this at every point in time is not always easy."
And we talk to Christophe Lumsden, Partner and Sustainability Lead at Ernst & Young AG Switzerland and EY's Global Climate Change and Decarbonization Leader. He says Climate Week Zurich is an example of how climate action continues to develop at a local level even as it faces pushback in parts of the world.
"Science is clear. Evidence is there. Climate change is not going away anytime soon," Christophe says. "Health repercussions are massive, human repercussions are big. So we just need to continue the movement."
S&P Global Energy is a founding partner and sponsor of the inaugural Climate Week Zurich.
