    Thomas Roberts, Aimie Hope, A Skelton (2017)Why on earth did I buy that? A study of regretted appliance purchases, In: Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences375(2095) The Royal Society

    If targets to reduce greenhouse gas emissions and thereby tackle climate change are to be achieved, it will be necessary to reduce both embodied energy costs (e.g. in terms of producing and manufacturing the products and services that society consumes) and operational energy costs. Reducing the number of purchases that people regret could be a first step in changing the overall dynamic of consumption patterns. This research looks at some potentially adverse effects of consumption on well-being (e.g. negative emotions), applying social practice theory to give insights into why people make purchases that they feel negatively about. This paper draws from: (i) findings of a national survey of over 2000 respondents which found that 53% of adults had reported regretting purchasing an electrical device at some point, and that 23% regretted making such a purchase within the past year; and (ii) a series of walking interviews around people's homes that provide detailed insights into the nature and extent of regretted purchases of electrical goods (e.g. resentment at built-in obsolescence, frustration at the pace of technological change). By combining the qualitative and quantitative data, we develop a typology of regretted consumption and explore the underlying factors that lead to such purchases. The paper concludes with a discussion of the policy implications of this research.

    Fostering local community tolerance for endangered carnivores, such as tigers (Panthera tigris), is a core component of many conservation strategies. Identification of antecedents of tolerance will facilitate the development of effective tolerance-building conservation action and secure local community support for, and involvement in, conservation initiatives. We use a stated preference approach for measuring tolerance, based on the ‘Wildlife Stakeholder Acceptance Capacity’ concept, to explore villagers’ tolerance levels for tigers in the Bangladesh Sundarbans, an area where, at the time of the research, human-tiger conflict was severe. We apply structural equation modeling to test an a priori defined theoretical model of tolerance and identify the experiential and psychological basis of tolerance in this community. Our results indicate that beliefs about tigers and about the perceived current tiger population trend are predictors of tolerance for tigers. Positive beliefs about tigers and a belief that the tiger population is not currently increasing are both associated with greater stated tolerance for the species. Contrary to commonly-held notions, negative experiences with tigers do not directly affect tolerance levels; instead, their effect is mediated by villagers’ beliefs about tigers and risk perceptions concerning human-tiger conflict incidents. These findings highlight a need to explore and understand the socio-psychological factors that encourage tolerance towards endangered species. Our research also demonstrates the applicability of this approach to tolerance research to a wide range of socio-economic and cultural contexts and reveals its capacity to enhance carnivore conservation efforts worldwide.

    Aimie Hope, Tom Roberts, I Walker (2018)Consumer engagement in low-carbon home energy in the United Kingdom: Implications for future energy system decentralization, In: Energy Research and Social Science44pp. 362-370 Elsevier

    There are competing visions for what future low-carbon energy systems might look like. However, it is likely that consumers will be more actively involved in managing their energy use. Consequently, there is likely to be some disruption to the current rhythm of everyday domestic social practices. This paper considers what we can learn from people who already take a more active role in managing their energy supply, with the aim of identifying transferable lessons that could be applied to future energy system decentralization. We compare two case studies focused on people with different levels of grid connectivity - people living off-grid on narrowboats and living in semi-grid connected houses in rural Norfolk. We find that where people had constraints on their energy use, they responded in three main ways. First, they diversified their energy supplies, including adopting traditional fuels such as coal and wood. Second, people planned, monitored and shifted their energy use, responding in ways favorable to micro-generation and demand-side response. Third, people curtailed energy use. We propose that UK households may respond in similar ways to decentralized energy. Finally we consider the implications of our findings for future energy policy aimed at decentralizing energy production and supply.

    At present, there is little guidance on how to communicate the dangers relating to hot weather events and on how to better prepare for them. Social responses to hot weather risks need to be a priority as populations around the world become more exposed to these under a changing climate. In this commentary, we argue that policy interventions focused on improving resilience to hot weather need to be more closely aligned with broader sustainability challenges and more effectively incorporate communication, behaviour, and social insights. With a particular focus on the UK, we highlight the risks of not taking these into account and outline ways in which policy-making on hot weather events could be improved, by drawing on international best practice and supporting decision-making within a range of relevant institutions across the health, transport and housing sectors.

    Extreme weather alerting systems are one of the central tools utilised in adapting to changing weather patterns resulting from climate change. This paper evaluates the effectiveness of the current alerting systems for hot and cold weather used in England to notify the health and social care sector of upcoming extreme weather events. We consider the views of stakeholders on the current system and explore their perspectives on the proposal to move towards an impact-based system. The paper concludes that while the current system is an effective tool, stakeholders feel they need to draw on additional material to assist with the development of an appropriate response. We also highlight that many stakeholders are concerned about the potential for creating alert fatigue due to a lack of clarity of the geographical area impact of some of the alerts. Consequently, there was a high level of support from stakeholders for the move towards an impact-focused system.

    Responding to the increased interest in addressing organisational sustainability issues using behaviour change strategies, this paper aims to propose a methodology for doing so from a different perspective – namely, sociology and social practice theory. Firstly, the background of behaviour change approaches and practice theory are discussed. Then a methodology for conducting a pro-environmental organisational change project is proposed. The methodology involves five key elements: detailed analysis of context, outlining a theoretical framework, establishing project boundaries, acknowledging connectivity of practices and choosing data collection methods. We illustrate the application of methodology by using examples of everyday consumables, energy and waste in a hospital trust in the South East of England. This approach has been effective for analysing routine and inconspicuous consumption within an organisation, as it considers individual attitudes and motivations as well as the structural and habitual nature of communities of practices. It allows researchers and managers to understand workplace consumption issues from several perspectives and identify the best angle from which to approach potential resolutions.

    The deployment of low-carbon energy supply technologies worldwide has sparked a debate about how to balance local environmental protection and our need for reliable low carbon energy. This books brings together ten years of research conducted by the Tyndall Centre for Climate Change Research and uses a range of case studies from carbon capture and storage to on-shore wind farms to explore the complex nature of disputes between a wide variety of stakeholder groups. Topics covered include: •the importance of context •the relationship between risk and trust •sense of place •role of the media An invaluable resource for researchers and readers in local or national government, industry or community groups who wish to deepen their understanding of controversy around low carbon technology and how to overcome it.

    Kavin Narasimhan, THOMAS MARK ROBERTS, MARIA XENITIDOU, GEOFFREY NIGEL GILBERT Using ABM to Clarify and Refine Social Practice Theory

    We use an agent-based model to help to refine and clarify social practice theory, wherein the focus is neither on individuals nor on any form of societal totality, but on the repeated performances of practices ordered across space and time. The recursive relationship between social practices and practitioners (individuals performing practices) is strongly emphasised in social practice theory. We intend to have this recursive relationship unfold dynamically in a model where practitioners and social practices are both considered as agents. Model conceptualisation is based on the principle of structuration theory—the focus is neither on micro causing macro nor on macro influencing micro, but on the duality between structure (macro) and agency (micro). In our case, we conceptualise the duality between practitioners and practices based on theoretical insights from social practices literature; where information is unclear or insufficient, we make systematic assumptions and account for these.

    Kavin Narasimhan, GEOFFREY NIGEL GILBERT, Aimie Hope, THOMAS MARK ROBERTS Demystifying Energy Demand using a Practice-centric Agent-based Model University of Surrey

    The rational choice framework is commonly used in many energy demand models and energy economic policy models. However, the notion of reasoned decision-making underpinning the rational actor models is less useful to explain the dynamics of routine household activities (e.g., cooking, showering, heating, etc.) which result in energy use. An alternative body of work collectively referred to as social practice theories offers a more practical explanation of routines. It is also argued that practices, i.e. the routine activities that people do in the service of normal everyday living, is at the centre of social change, and hence should be the focus of interventions concerned with demand reduction. One of the main criticisms of social practice theories, however, is that the concepts proposed are high-level and abstract and hence difficult to apply to real-world problems. Most existing practice-centric models are also abstract implementations. To address this gap, in this paper, we present a concrete, empirically-based practice-centric agent-based model to simulate the dynamics of household heating practices. We also use the model to explore consumer response to a simulated price-based demand response scheme. We show how a practice-centric approach leads to a more realistic understanding of the energy use patterns of households by revealing the underlying contexts of consumption. The overall motivation is that by gaining insight into the trajectories of unsustainable energy consuming practices, it might be possible to propose alternative pathways that allow more sustainable practices to take hold.

    The unbridled consumption of clothing threatens the environment. A discussion is developing around the adoption of new materials and economic models to reduce the impacts of clothing production and use. We discuss these emergent technologies in the wider historical setting of the Anthropocene. The history of human-environmental interactions is interwoven with the development of international garment economies. This article provides an account of how changes in clothing manufacturing and consumption patterns have affected environmental systems, focusing on laundry practices in Britain. We draw on closed-loop recycling to discuss how ideas from clothing businesses privilege the status quo and technological change. Optimistic solutions to fashion and sustainability challenges are an example of mechanisms that are responding to a utopian eco-modernist argument that human systems can adapt and prosper in a changing world. Such flawed solutions hide from view more radical visions to transform the relationships among fashion, technology, and the environment.
