Dr. Eckart von Hirschhausen opens the panel with an input and a question: Why do we talk about gas, coal, batteries, mercury and electricity the way we do? He then steers the discussion into one of the most pressing questions of the transition: A truly circular economy needs energy systems that don’t just achieve climate neutrality — they need to have a positive impact. Drawing on the report Energy & Cradle to Cradle, the panel explores whether and how renewable energy and C2C design principles must be thought together: from circular infrastructure to systems that give more back to nature than they take and in doing so, unlock new business models.
