In 1900, Chicago successfully completed a massive and highly innovative engineering project – reversing the flow of the Chicago River so that it emptied into the Mississippi River instead of Lake Michigan. For over 50 years, the Chicago River has been dyed green to celebrate St. Patrick’s Day. Now Green takes on a whole new meaning for Chicago as the City has taken the lead on a number of sustainable initiatives from Climate Action Plans, to Green Roofs, to the Green Commodity Exchange. This week we take a look at the people that make Chicago a "Green City".

Join Robert Colangelo as he interviews guests Sadhu Johnston and Kimberly Worthington, City of Chicago, Kelly Reiss, The Center for Green Technology, Luca Serra, Soldier Field, Mark Minor, RTA and Alderman Manny Flores to show you how the Second City is first in many new green initiatives.
