This week on Smart City, you’ve heard of boycotts to convince people not to buy targeted products or at targeted places. But when is the last time you’ve heard of organizing purchasing to get companies to do the right thing? That’s the approach of CarrotMob. Based in San Francisco, CarrotMob creator Brent Schulkin is challenging companies to behave in environmentally responsible ways and get rewarded with purchases by people who care.

And we’ll talk about eight emerging trends affecting cities with Wakako Takagi and Tisha Johnson.

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. For the webcast, times for the broadcast in other cities and to sign up for the podcast, visit our website.
