Dell Computer Corporation asserts a philosophy of corporate responsibility geared toward “enabling human potential” through technology and making access to green technology easier for all, including the underprivileged ( "Corporate Responsibility", 2012, par. 1-2). For this philosophy to translate into meaningful practices and actions, Dell must use performance measures. As Epstein (2008) points out, “measurement is critically important because it links performance to sustainability principles and facilitates continuous improvement” (p. 164). Given the size and scope of Dell Computer Corporation, there are numerous relevant performance measures that could be used to evaluate the company's sustainability practices and progress. However, two particular sustainability factors appear to emerge with particular importance regarding Dell's performance indicators. These two factors are the energy efficiency of Dell products and the recycling of used electronic products, including disposing of waste products and donating used products to those in need. Given the widespread use of technology in today's world, the energy consumed by computers and other electronic devices is a concern. The IT sector is estimated to be responsible for more than 2% of carbon dioxide emissions released globally; this is approximately the same as in the airline industry (“Dell Aims to Demonstrate,” 2008). Manufacturers like Dell make powerful computer processors whose power consumption far exceeds the processor's increased utility (“Dell Aims to Demonstrate,” 2008). Additionally, consumers typically leave their PCs running and businesses leave servers running almost all the time, wasting a great deal of......half of paper......com/us/en/corp /cr .aspx?~ck=btDell aims to prove that energy promises aren't just greenwashing.
