Lisa Napoli: A new survey shows 83 percent of people around the world are willing to change their lifestyles in order to help the environment.

Ashok Gupta: It's also important to lock in some of these policies for future mayors to really see this as a fundamental change.

Chicago is a member of the Clinton Climate Initiative. Former President Bill Clinton is expected to be on hand for next week's announcement.

I'm Sarah Gardner for Marketplace.
