Comerica has been named among the top 500 "Newsweek Green Companies" in 2012. Comerica ranked no. 372 overall, and no. 39 among financials. According to the publication, "To produce the 2012 Green Rankings, Newsweek collaborated with leading environmental research providers, Trucost and Sustainalytics, to assess each company’s environmental footprint, management of that footprint, and transparency."
Further, Newsweek indicated that "In recent years, the Financial industry has made notable improvements in managing its direct environmental footprint through energy-efficiency initiatives and reductions in waste and water consumption. An emerging trend among large Financial companies is to set quantitative commitments for financing sustainable projects and activities, such as “green mortgages” or loans for home energy improvements. Companies leading in this area are setting “sustainable financing” targets over a 10-year period, and are exceeding their own commitments."
Comerica was named to the Newsweek Green Rankings® in 2009, 2010 and now 2012.
