Introduction to the special issue on practice-oriented approaches to sustainable HCI

Since Blevis's seminal paper [Blevis 2007] in 2007, environmental sustainability has established itself as a mainstream concern for HCI. After an initial flurry of excitement about the potential for existing HCI techniques, such as persuasive computing and interaction design, to contributemeaningfully to increasing sustainability, we have begun to recognize that the complexity and apparent intractability of working towards sustainability is providing serious challenges to current HCI ways of approaching problems. For example, some are working to deepen the engagement between HCI and established approaches of environmental psychology [Froehlich et al. 2010] and behavioral theory [Hekler et al. 2013] in order to develop more rigorous methods and theoretical connections for pursuing sustainability. Others are deploying and evaluating eco-feedback technologies at a scale not yet common in HCI [Erickson et al. 2013] to get a better sense of their effects and potentialities. Thus, sustainability is becoming not simply a problem that HCI can contribute to solving, but also an opportunity to understand the limits of HCI as it is currently constituted and to develop new possibilities for the discipline.
