Incorporating sustainability into information technology management

Abstract

Information technology (IT) industry accounts for approximately 2% of global carbon dioxide (CO2) emissions. Data centres use a significant amount of energy. This has become problematic during the last few years. Power intensities have been increasing over time, largely because of the increasing heat density of IT equipment. The number and usage of PCs have been rapidly increasing worldwide. By implementing IT sustainability programmes, organizations can drastically reduce the amount of energy spent, develop efficient technology products, keep e-waste out of landfills and adopt recycle and reuse programmes. Using more efficient technologies can help consume fewer resources and emit less waste. This article discusses various aspects of sustainable IT programmes and proposes sustainability metrics for IT to demonstrate a positive impact on the environment.
