As an early example of empirical and theory-building Green IS research, this work makes several
contributions to the IS literature. First, this paper introduces and describes a new category of Green
IS: carbon management systems. Although Green IS may take many forms (Mingay, Tratz-Ryan, &
Stokes, 2010) and target different environmental problems, much of the extant research considers
Green IS at an aggregate level (e.g., Chowdhury, 2012; Melville, 2010). In order to fully understand
the variations and nuances of the relationships between information systems and environmental
sustainability, it is necessary to unpack the black box of Green IS. Therefore, rather than taking a
broad view of the subject, this study focused on an emergent category of Green IS. Specifically, the
study examined the situation of cross-over IS, where personal-CMS were used in organizational
settings, and, in the process, uncovered a number of new patterns with respect to the interactions
between people, technologies, and the natural environment.
