Earth Week 2015 was April 20-24. Sustainable marketing guru Jacquelyn Ottman (right) inspired more than 140 people from the Illinois campus and the community with her keynote address on Earth Day (April 22). Other events included awards ceremonies for “green” competitions — including 24 honorees from our own Certified Green Office Program — plus an Arbor Day celebration that drew more than 70 people to a tree planting on the Main Quad near the Henry Administration Building.
