This week on Smart City we’ll talk to the creator of one of my favorite websites, Matt Lerner is the Chief Technology Officer of, a company that builds software for civic life. He’ll tell us about making software that makes the world a better place.

And we’ll talk to Sadhu Johnston. Sadhu is completing his tenure as Chicago’s Chief Environmental Officer where he’s been making Chicago a better place. He’ll tell us about the challenges in implementing real change in the city, and how cities are co-operating instead of competing to make a real difference in climate change.

Smart City is a syndicated, weekly hour-long public radio talk show that takes an in-depth look at urban life: the people, places, ideas and trends that affect us all. Host Carol Coletta, president and CEO of CEOs for Cities, talks with national and international public policy experts, economists, business leaders, artists, developers, planners and others on the pulse of city life for a penetrating discussion on urban issues.

Smart City is broadcast at 6 a.m. Saturday and Sundays on WKNO-FM, but it is also webcast and podcast so you can listen to it anytime you like. For the webcast, times for the broadcast in other cities and to sign up for the podcast, visit our website.
