"As delegates gather at the COP 27 Climate Summit this week in Egypt, we’re reminded of the need for swift action and ideas that scale. The leaders in this week's podcast are investing in new technologies, new incentives, and most importantly, new approaches. That can get us to a more sustainable world.

These interviews recorded at the annual meeting in Davos, the Sustainable Development Impact meeting in New York and the Urban Transformation Summit in Detroit show the range of ideas that change makers of all stripes are pushing forward.

Each drives home one key idea: that while sometimes new technologies or capabilities can always be developed, there's so much we can accomplish with the tools, will and creativity that's already in place."
