During the last half decade, various theories, concepts, and models have been established to make organizations more environmentally sustainable. The IS community had their share with the Green IS/IT domain. As it turned out most of these concepts took a very functional approach, not making a good fit for business process oriented organizations. To fill this gap the research stream of Green Business Process Management (GBPM) arose. In this paper we develop and discuss various capabilities that organizations should have in order to actually take advantage of GBPM. We call these capabilities GBPM readiness.
