This paper responds to contemporary design contexts that frequently contain complex interdependencies of human and non-human actants. To adequately represent these perspectives requires a shift towards More-Than Human Centred Design. The Internet of Things is one context that demonstrates this need. The 'things' within such networks transcend their physical forms and extend to include algorithms, humans, data, business models, etc., and each imports independent-but-interdependent motivations and perspectives. Therefore, we use the Internet of Things to clarify our proposition and to convey our three contributions. First, we review the expanding corpus of contemporary Human-Computer Interaction research that seeks to expand the notion of Human Centred Design by moving beyond the dominant anthropocentric perspective. Second, we introduce a novel design metaphor, 'constellations', which allows both the interdependencies and independent perspectives to be considered. Third, we provide an account of a speculative design to demonstrate how it may be put into practice.

Research into the values motivating unsustainable behavior has generated unique insight into how NGOs and environmental campaigns contribute toward successfully fostering significant and long-term behavior change, yet thus far this research has not been applied to the domain of sustainable HCI. We explore the implications of this research as it relates to the potential limitations of current approaches to persuasive technology, and what it means for designing higher impact interventions. As a means of communicating these implications to be readily understandable and implementable, we develop a set of antipatterns to describe persuasive technology approaches that values research suggests are unlikely to yield significant sustainability wins, and a complementary set of patterns to describe new guidelines for what may become persuasive technology best practice.

In this paper we explore the motivations for, and practicalities of, incorporating 'implications for adoption' into HCI research practice. Implications for adoption are speculations which may be used in research projects to scrutinize and explore the implications and requirements associated with a technology's potential adoption in the future. There is a rich tradition within the HCI community of implementing, demonstrating, and testing new interactions or technologies by building prototypes. Usercentered design methods help us to develop prototypes to and move toward designs that are validated, efficient, and rewarding to use. However, these studies rarely shift their temporal focus to consider, in any significant detail, what it would mean for a technology to exist beyond its prototypical implementation, in other words how these prototypes might ultimately be adopted. Given the CHI community's increasing interest in technology-related human and social effects, the lack of attention paid to adoption represents a significant and relevant gap in current practices. It is this gap that the paper addresses and in doing so offers three contributions: (1) exploring and unpacking different notions of adoption from varying disciplinary perspectives; (2) discussing why considering adoption is relevant and useful, specifically in HCI research; (3) discussing methods for addressing this need, specifically design fiction, and understanding how utilizing these methods may provide researchers with means to better understand the myriad of nuanced, situated, and technologically-mediated relationships that innovative designs facilitate.

This paper challenges the sustainable HCI community to move away from a focus on demand and instead address climate change as a supply problem. We identify a new route to impact, namely to focus on addressing the psychological barriers that prevent the political action needed to affect the supply of fossil fuels. Five barriers are explored as a means of revealing new research objectives for the community.
