Forrester clients submit roughly 20,000 analyst inquiries each year. In aggregate, these one-on-one interactions create a map of topical hotspots among Forrester's client base, with important insights for technology marketers. Since initiating research on green IT trends in early 2007, Forrester analysts have fielded a steadily growing number of client inquiries on green topics, including corporate sustainability planning, data center energy efficiency, IT recycling, and green marketing tactics. This set of inquiries provides a window into the growing mindshare that environmental considerations have among IT professionals and their suppliers.
