Elizabeth Barry, MMC's Sustainability Officer, said: "We are pleased to achieve the prestigious LEED Gold certification for MMC's Chicago offices, the first of many such designations anticipated across our real estate portfolio. With several of our locations in the process of attaining LEED certification, we strive to integrate green strategies into the design, construction, and workplace practices throughout our offices. MMC has made a strategic commitment to sustainability and we are dedicated to implementing changes that benefit our employees, our clients, and the communities where we operate."

MMC achieved LEED certification after the rigorous examination of its energy, lighting, water and material use as well the implementation of other sustainable strategies in the overall work environment. The green strategies MMC employed in the construction and material selection were designed to reduce greenhouse gas emissions and contribute to a healthier work environment not only for MMC's approximately 600 employees in its offices at North Wacker, but for the community at large.
