As part of Sustain Dane's MPower Business Champions Program, 17 area businesses have spent the past year working to reduce their environmental impact. They have successfully conserved energy, lowered waste, increased alternative transportation, and gone green in their business processes and workplace environments. On Friday, the 2013 MPower Business Champions will highlight their sustainability work and results during the annual MPower Champions Public Showcase. www.2013mpowershowcase.eventbrite.com
