This article examines the extent to which the initiatives determined as Green ICT are reflected in the lifecycle of information and communication technologies (ICTs) in Czech Small and Medium Enterprises (SMEs). The research model is based on the ICT Lifecycle viewpoint that from the perspective of non-ICT businesses consists of three phases – ICT procurement, ICT use and End of ICT use. The results of our research conducted via questionnaire survey among 61 respondents indicate a significant potential among businesses for improvement in all ICT lifecycle phases. The utilization of this potential can increase their competitiveness not only by achieving cost savings in the operation of ICT, but also by contributing to their sustainable development.
