Energy poverty affects 550,000 homes in the Netherlands yet policy interventions to alleviate this issue are rare. Therefore, we test two energy coaching interventions in Amsterdam: a static information group (n = 67) which received energy efficient products and one energy-use report, and a smart information group (n = 50), which also had a display providing real-time feedback on energy-use. Results across both groups, show a 75% success rate for alleviating energy poverty. On average homes reduced monthly electricity consumption by 62 kWh (33%), gas by 41 m3 (42%), bills by €104 (53%) and percentage of income spent on energy from 10.1% to 5.3%.

The multiple unfolding crises that threaten life on Earth keep many of us awake at night and leave us at a loss about how to meaningfully respond. Much of humanity's efforts to address the crises are ultimately aimed at upholding the current unsustainable paradigm of infinite growth and exploitation of both natural resources and humans. In this paper, we offer the Two Loops model of change as a framework for understanding the interrelated crises of our times - the meta-crisis - to help us find clues for personal agency and also hope. Notably, Two Loops asks us to face the need for hospicing and grieving what is dying, reorienting computing to work to what comes after and what must be protected and saved. We work through the model's various spaces for agency, i.e. innovating, naming, connecting, nurturing, illuminating in the emergent System; and stewarding, hospicing, composting and transitioning in the dying dominant System. We suggest examples and clues as to where computing and HCI professionals' agency might lie in and between the two Systems in terms of skills, tools, practices and projects. Moving forward, we welcome a deeper, large-scale collaborative mapping of the possible contributions of our profession, to include all the different specialisms of our field in the picture of how we can be of service to liveable futures.

This paper describes a participatory pastcasting workshop designed using action-oriented design research methods in close collaboration with practitioners from Omställningsnätverket (the Swedish Transition Network) as co-researchers. The paper deepens the theoretical understanding of how to implement pastcasting, a novel addition to futures studies methodologies aimed at societal transformation. We outline the process of designing the workshop format and insights from running the workshop in two different locations in Sweden. We propose that exploring complex problems such as climate change as if they have already been solved in an alternative, more desirable present and then imagining what we did to address them in the recent past is liberating and generative of ideas for action. We argue that this methodology is a powerful addition to other futuring techniques as it concretises urgently needed societal transformations and brings them closer to people and their communities.

The United Nations Environment Programme (UNEP) released design indexes for sustainable neighbourhoods, including self-sufficiency, community plot ratio and civic generosity. However, they are developed from an urban planning perspective and not researched in relation to: a) the citizen perspective and b) how citizen interactions can contribute to the environment. Therefore, this research tests a novel set of indexes with an underused method of ethnographic video interviews with 14 citizens of a known sustainable neighbourhood in Stockholm, Sweden. A thematic analysis conducted on 28 h of interview data collected over a 4-week period yielded 5 main themes, from outdoor public spaces. Self-sufficiency findings suggest that citizens 1) perceive small scale self-sufficiency to be challenged by large scale structural efficiency and 2) circular actions with food waste to biogas can develop the self-sufficiency index further. Community plot ratio findings suggest that citizens 3) perceive community spaces to be accessible for all but not used by all. Civic generosity findings suggest citizens 4) perceive an imbalance between self-interests of the individual versus collective interests of the community, while 5) experienced citizens feel personally responsible to pioneer civic generosity interactions. UNEP indexes for designing neighbourhoods can define local sustainability, however, our findings support this, only if they can be acted upon by the citizens who live there.

Today there is a wealth of data available detailing the climate impact of our actions, including the CO2 emissions from academic flying. Despite this, such data is hard to engage with in the abstract, leading to little practical action. In this paper, we investigate how to support processes of collectively working through and making sense of environmental data about academic flying through data physicalisation. Drawing on the results from a series of workshops with stakeholders at our own university, in which we have designed and deployed a data physicalisation of flight data, we describe this process and discuss lessons learned with a focus on material, engagement with data and ethics.

The rapid development of esports over the last two decades has been in some ways a challenge to the established sporting world. However, esports has largely developed according to the sportification model (Guttman, 1978), over time becoming progressively more organised, specialised, standardised, regimented, and rationalised. Competitive computer gaming is today following a similar trajectory as other sports have done in the past and has gone from being a leisure activity to becoming a competitive activity with organisations, professional players, and international competitions. This chapter gives a closer look at the ongoing sportification of esports in general and, more specifically, how this process has played out in Sweden. Similarities and differences in the sportification of esports and a more traditional sport - cross-country skiing - will be analysed. How have esports worked with organisation, regimentation, rationalisation, and standardisation? Building upon archival sources, earlier research, and interviews with representatives from Swedish esports organisations will conclude the chapter.

Effectively communicating vital sustainability topics, such as personal CO2e emissions stemming from daily activities, is challenging since there is a general lack of”carbon literacy.” Despite efforts, like employing data visualizations, conveying this information in engaging and memorable ways remains difficult, often resulting in rapid forgetfulness. Our demonstration presents a pedagogical approach aimed at addressing this challenge. Through the integration of surprise elements, data physicalization, and embodied learning, we have developed two interactive mediated non-digital learning experiences focusing on CO2e emissions from food and from consumption. At the core of our pedagogical approach are physical artifacts representing CO2e emissions where the weight of the artifacts directly corresponds to the CO2e emissions they represent. By employing a structured interactive pedagogical setup involving peer discussion, hands-on manipulation of the artifacts, and subsequent explanations, we have created an engaging experience that encourages long-term learning.

Computing within Limits invites considerations of limits andconstraints in design practice. We compare two projects whichintegrate constraints, the reduction of academic air travel and asolar powered internet, to show a distinction between twoapproaches to arriving at constraints. In the case of reducingacademic air travel, the problem which greenhouse gas emissionspose for business-as-usual academic travel is addressed byproposing constraints on future flying. Constraints in the Flightproject can be understood as a process of commensuration, ofcomparing that which is to be constrained according to a commonmetric. This gives rise to a future of academic travel understood inrelation to CO2 emissions and reduction targets. In the secondcase, we have explored the solar internet as a specific way tointroduce constraints in the context of the rising electricity useassociated with internet infrastructure. In the Solar Internetproject, constraints have been approached relationally anditeratively, in reconfigurations of internet use practices and designpractices, including the solar internet imaginary and the scale ofbattery and power supply.

We compare these two approaches, drawing on vocabulary fromSociology of Quantification and Science and Technology Studies,to help articulate their respective implications, while alsoacknowledging what they have in common, e.g. the ability toexpand the frame of what is made relevant for design practice.The case of the Flight project suggests that constraints as aprocess of commensuration can be fruitful when pursuing aunified future, intervening over time with a trajectory towards aquantifiable target. On the other hand, when trying to account forindirect effects and the future as multiple, the introduction ofconstraints can better be understood as con-figurations, with afuture negotiated iteratively in design practice. Rather thanthinking about constraints as essentially requiring one or the otherapproach, we suggest that problems and the introduction ofconstraints may be more or less amenable to either approach at aspecific time.

[Background] While degrowth is a socio-economic paradigm still known to relatively few, the latest Intergovernmental Panel on Climate Change (IPCC) reports emphasise its importance in investigating and realising pathways to sustainability. There is increasing evidence that information and communication technology (ICT) plays an important role in sustainability pathways. But research about the relationship between degrowth and ICT is yet scarce. [Aims] We aim at exploring the relationship between degrowth and ICT to identify emerging themes and research implications. [Method] We conduct an exploratory literature review to gather background knowledge and complement it with focus groups, expert interviews, and Reddit discussions to elicit knowledge, reflections, informed opinions and attitudes towards degrowth. [Results] Several themes that require careful consideration emerge in our study, such as the effect of terminology, the reliance on high-tech solutions, and trade-offs that come with decreasing the use of ICT. [Contribution] We also define the concepts degrowth of ICT and degrowth by ICT, and discuss how degrowth and ICT relate to each other. We hope our work enables further research into the role of ICT in degrowth scenarios supporting a shift to strong sustainability.

The widespread awareness and the sense of urgency and helplessness regarding the ongoing sustainability crisis (climate change, biodiversity loss etc.) can evoke feelings of grief, sorrow, despair and anxiety. Those emotions are seldom discussed in computing or in computing education. They can have detrimental effects on the well-being of students and others, and also lead to inaction. But concern can on the other hand also be a catalyst for learning. In this paper, we present results and reflections from a research and development project in our introductory course to sustainability and ICT focusing on emotions in sustainability education. We focus on “eco-anxiety” and ask: 1) How is eco-anxiety communicated by students and teachers?, 2) In what ways do students receive support to deal with eco-anxiety? and 3) What could be done to better address eco-anxiety in computing education? We here present an analysis of how we have responded to the phenomenon of eco-anxiety, what activities have been added to the course and an evaluation of these interventions. The results are based on joint reflections that have been guided by literature, a small-scale ethnographic study as well as a course evaluation. The paper will end with recommendations for other ICT4S educators on how they can start addressing eco-anxiety in their education.
