Globally, efforts are undertaken to promote the diffusion of Green-IS. The aim is to mitigate negative environmental impacts of IS itself and to leverage IS’ potential in the creation of environmentally sustainable societies. A particular Green-IS, essential for the intended modernization of energy systems, is the Smart Metering Technology (SMT). It facilitates demand-reduction and -shifting and is supposed to trigger behavioural and economic changes in households’ energy consumption. While technology adoption in the workplace has been studied extensively, scientific evidence as to residential settings is limited. Likewise, the IS-community has hitherto been reluctant in addressing issues regarding environmental sustainability (Melville 2010). This study aims at bridging these gaps by investigating the factors influencing private consumers’ intention to adopt Green-IS. We present a comprehensive research model which was empirically validated by employing data collected from 708 potential adopters. The model was found to explain a substantial proportion (.55) of the variance. The results implicate that apart from the major determinant attitude, intention is driven by environmental concerns and social influence. The study’s outcomes will help refining researchers’ understanding of private Green-IS adoption and will be useful for diverse stakeholders interested in encouraging SMT-adoption. Theoretical and practical implications are discussed
