A Comparative Analysis of Green ICT Maturity Models

Maturity models have become a common tool for organisations to assess their capabilities in a variety of domains. However, for fields that have not yet been researched thoroughly, it can be difficult to create and evolve a maturity model that features all the important aspects in that field. It takes time and many iterative improvements for a maturity model to come of age. This is the case for Green ICT maturity models, whose aim is typically to either provide insight on the important aspects an organisation or a researcher should take into account when trying to improve the social or environmental impact of ICT, or to assist in the auditing of such aspects. In fact, when we were commissioned a comprehensive ICT-sustainability auditing for Utrecht University, we not only faced the need of selecting a Green ICT maturity model, but also to ensure that it covered as many organisational aspects as possible, extending the model if needed. This paper reports on the comparison we carried out of several Green ICT maturity models, how we extended our preferred model with needed constructs, and how we applied the resulting model during the ICT-sustainability auditing
