Greenpeace released its annual ranking of IT companies in terms of how “green” they are. Greenpeace uses a matrix consisting of a company’s “IT climate solutions,” its “IT energy impact” and it’s “political advocacy” to determine its rankings. To score well, a company has to invest in IT solutions that reduce carbon emissions, reduce its own energy footprint, and speak out and lobby for better greenhouse gas regulations. Google won the day, mainly because of its transparency, its 20 percent renewable energy sourcing, and its aggressive clean energy investments. Oddly, Apple and Facebook are not included in the rankings because they don’t produce products geared toward enterprise IT carbon savings. Though certainly their products drive an enormous amount of computing that may or may not be very clean.
