In recent years, designers are increasingly active in dealing with societal transitions, using design and social innovation to drive systemic change. Transitions are long-term processes of systems change toward more desirable alternatives. In transition design, designers conceptualise and implement transition interventions to influence the behaviours, practices, and lifestyles of people and society. However, little is known about the design processes that lead to such interventions or the reasoning patterns that support a design process toward conceptualising transition design interventions. In this paper, we explore how a transition design rationale—a design rationale tailored to the complexities of transition challenges—supports designers in making design decisions and clear argumentations for how proposed interventions foster desired transitions. We present two studies that investigate the development and application of a transition design logical framework. The first study was a grounded theory study on design reasoning, in which designers in a consortium working developed interventions to foster the transition of the Dutch food system to less food waste. In this first study, the designers applied the transition design logical framework to strengthen the design reasoning for the intervention proposals. The second study consisted of two evaluative workshops with designers who applied the framework to design interventions that foster desired systems change. Our findings indicate that our transition design logical framework supports designers in framing the transition context in a way that makes it manageable to design for, increasing confidence in the efficacy of proposed transition interventions. We found that a key challenge for designers reasoning toward transition interventions is articulating individual and system behaviour change integrally. We conclude the paper by reflecting on avenues for methodological development to further support transition design reasoning toward interventions. Additionally, we call to the systemic and transition design communities to continue refining and expanding a shared repertoire of behaviour change mechanisms that can effectively drive systemic change. @en

The Netherlands Climate Change Agreement aims to reduce CO₂ emissions and seismic events by halting natural gas usage by 2050. This will require widespread societal acceptance by 90% of households. The study investigates the social acceptance of a district heating network (DHN) among social housing tenants in Haarlem, Netherlands. The findings of a survey administered to ninety-five tenants revealed a substantial level of support for the DHN project. A significant portion of respondents, 75%, expressed their approval for the DHN, surpassing the legally required threshold of 70% for implementing building retrofits. Findings imply that although the participants possess an adequate comprehension of the rationale for energy transition, their familiarity with the precise particulars and practical information pertaining to the proposed transition to DHN is inadequate. The level of trust in housing corporations, energy providers, and the municipality is uniformly low, indicating a lack of institutional trust. Generally, the interpersonal trust among tenants tends to be lower than their trust in the broader public, which in turn restricts their capacity for self-organization and exercising influence over energy institutions. Although DHNs are typically regarded as environmentally friendly and secure, there are several challenges that need to be addressed, including the uncertainty about who will cover the costs of transitioning and the doubts surrounding DHN feasibility (warmth and reliability). We suggest implementing interventions to improve tenants' comprehension of the DHN project's particulars (capability), provide practical information regarding costs and feasibility (motivation), and foster trust at both interpersonal and institutional levels (opportunity).

Having directly observed one of the most rapidly spreading global pandemics, we understand more than ever the power of contagion. In today’s interconnected world, trends originating in one corner, whether it’s a disease, clothing fashion, or an online social media challenge, can swiftly gain momentum on the opposite side of the globe, often within a matter of days or even hours. This rapid diffusion is enabled by our globalised world and developments in technology and ICT. Social networks and social influence are strong influencers in shaping our attitudes and behaviour. However, this influence can be a double-edged sword. On the one hand, it brings people and cultures together, it facilitates the exchange of information and resources. On the other hand, it can be easily exploited to spread misinformation and exert pressure on individuals to engage in negative behaviours like smoking or violence. This phenomenon is commonly referred to as ‘social contagion.’ In this handbook you can find the result of ENRGISED: Engaging Residents in green energy investments through social networks, complexity and design. In 2019 we saw an impasse in the Dutch energy transition, where many technologies were available but not many people were taking action. Since then, global events, such as Covid 19 and the invasion of Ukraine, have disrupted our world and the energy market. In the midst of these changes we conducted our research. Between 2020 and 2023, we studied the use of social contagion - social influence and the effect of social networks - towards the energy transition in neighbourhoods in the Netherlands.@en

The food system in Vietnam is changing whilst the middle class is growing. Agrifood smallholders have the strengths of responding to the changing needs of the middle class by offering freshness, proximity and convenience but they also face increasing competition from larger and international firms. At the same time, issues with food safety are prevalent and a rising concern among consumers. For this study we completed sixteen co-creation workshops between local agri-food smallholders and consumers. The goal of these workshops was to explore the value of participatory processes, non-hierarchical decision making and creativity for smallholder firms in Vietnam through co-creation workshops focused on sustainability. The outcomes show that the workshops can stimulate customer understanding and participatory processes among the smallholder businesses, but creativity in the form of novel ideas less so. The workshops did not result in directly feasible or manageable product and service concepts. The topic of sustainable food opened a dialogue: insights between the firms and customers on this topic were mutually rich. The outcomes suggest that co-creation workshops can create a sense of community and urgency for sustainability. In the future, the challenge for smallholders is to invest in participatory processes with a long-term view on sustainability as well as come to practical design outcomes on the short term@en

To reach the 2050 climate goals, massive socio-technical transitions are required. For requisite impact, not only industry and government need to transform, but a critical mass of society must adopt greener alternatives. However, people have a tendency to maintain the status quo and often resist change until a final moment of urgency or crisis. This study focuses on the Dutch energy transition. We propose and illustrate how social influence or ‘social contagion’ can be used to activate communities of citizens, not just individuals, to adopt greener alternatives; leveraging the strength of design in shaping behaviour (change). Lying at the intersection of design, psychology, and sociology, our study contributes toward theories of scaling behaviour change and proposes practical tools to establish change through design. The results show how design can play a critical role in shaping sustainable systemic transitions and argues for pluralistic applications of design thinking.@en

The speed of energy transition in the Netherlands is low, in contrast to its 2050 climate change target of net-zero emissions. The transition requires 7.5 million households with natural gas connections, to move to renewable energy sources. The main challenge is not technical, many viable options are already available, but social: people will need to be supported to decide and act. In this paper, we identify interventions that could activate change within energy communities, through 19 interviews conducted in March 2021 in Austerlitz, Zeist municipality, The Netherlands. Interview questions were guided by the Capability, Opportunity, Motivation, and Behavioural (COM-B) change model. The model explains factors that affect people’s behaviour. Results indicate that renovation and energy transition are viewed as two separate processes. Austerlitz homeowners are waiting for the government to lead the energy transition process, while they continue to renovate their homes to improve comfort, aesthetics, safety, and convenience. Also, current interventions towards activating households are piecemeal and more focused on creating external opportunities (such as financial support), and barely address the psychological capabilities and motivation factors (belief, attitude, social norm, and perceived behavioural control). To boost psychological capabilities and motivation, we recommend interventions that enhance homeowners’ belief that the energy transition is part of their long-term home renovation plans, for their own benefit, to motivate them to drive the energy transition process. Interventions may include ‘show’ or ‘display’ houses where energy transition was combined with renovations and highlighting inspirational energy transition stories on the municipality website.@en

Food products require significant amounts of energy and water throughout their lifecycle, yet humanity wastes 1.3e9 tons of food on a yearly basis. A large part of this waste occurs during the consumption (post-retail) phase of the food system as avoidable food waste, the discarded edible (parts of) food products. In this study, we explore the effects of avoidable food waste on the Food-Energy-Water nexus. We show that the 344 million tonnes of global avoidable food waste is responsible for squandering 4e18 J of energy and 82e9 m3 of water. While there are important regional differences in terms of avoidable food waste due to varying diets and waste incidences, these energy and water losses are rivaling the electricity and the blue water use of populous nations, and adding to needless pressures on the environment.@en

In a recent study, we identified seven key circular competencies for design: (1) Design for Multiple Use Cycles, (2) Design for Recovery, (3) Circular Impact Assessment, (4) Circular Business Models, (5) Circular User Engagement, (6) Circular Economy Collaboration, and (7) Circular Economy Communication. These were derived from small‐scale studies with designers working in the Netherlands. We set out to assess to what extent this set of seven competencies is recognized by an international group of designers and to evaluate whether any competencies are missing. We used an online survey to collect data from 128 respondents from 25 countries working on circular economy projects. The survey results showed that respondents use and have expertise in all seven competencies and they stressed the practical importance of two new competencies: Circular Systems Thinking and Circular Materials and Manufacturing. The resulting set of nine key competencies is the first internationally verified, coherent set of key circular economy competencies for design. This set will strengthen the pedagogical base of design for a circular economy and will guide the development of circular design methodology.

This study addresses what competencies (knowledge, skills, and attitudes) designers need in order to successfully design products and services for a circular economy. Existing literature, though sparse, has identified a number of circular economy competencies for design. Yet, a coherent overview is lacking. To complement the competencies found in the literature with insights from practice, we conducted 18 semi-structured interviews with design professionals. Our study identifies seven circular economy competencies for design: (1) Circular Impact Assessment, (2) Design for Recovery, (3) Design for Multiple Use Cycles, (4) Circular Business Models, (5) Circular User Engagement, (6) Circular Economy Collaboration, and (7) Circular Economy Communication. We used a general sustainability competencies framework to categorize our findings. Interestingly, we did not find evidence of the Systems Thinking competency in practice, although in the literature it is mentioned as a relevant competency for design for a circular economy. In addition, we found that methods and tools are still largely lacking or in a premature stage of development. We conclude that design for a circular economy can be seen as an upcoming, independent field within the sustainability domain, and that requires a specific set of competencies, methods, and tools. Our overview of circular economy competencies for design can guide the development of relevant methods and tools, circular economy-based design curricula, and training programs in the future.@en

This paper aims to understand the value of synergy between the field of design and that of transition management for sustainability. Six potential values of synergy are identified: (1) enriched methods of retrieving knowledge of current objects and current systems; (2) providing boundary objects in transition arenas beyond language games; (3) actively envisioning the effect of design things during and beyond their lifetime; (4) intensified reflexivity in design practices and projects; (5) more prototyping activities to leave traces of transition activities in everyday life; (6) greater focus on building interactions through a broader range of co-creation activities. The paper also identifies four possible pitfalls of synergy between the two practices. The paper is grounded in literature but is meant to be a stepping stone towards experimentation in practice; where knowledge, approaches, methods and experience of both fields are combined to intensify the impact on sustainability@en

Limited research has been done on design competencies for a circular economy in practice. Yet, an overview of design competencies for a circular economy would be useful to understand which topics should be emphasized in both education and practice. This paper focuses on deriving circular economy competencies for product designers working in industry. The study consisted of three focus groups with twelve designers that are actively exploring circular economy opportunities in an industrial product design context. We derived six design competencies for a circular economy: (1) circular economy understanding, (2) circular economy storytelling (3) setting circular criteria, (4) assessing circular solutions, (5) connecting reverse logistics with users, and (6) design for multiple use cycles. These six competencies are presented and reflected upon by comparing them to competencies found in literature. Two of the competencies found (i.e., circular economy understanding and storytelling) are new compared to those mentioned in literature. The other four competencies found in this study overlap or further specify competencies mentioned in literature. Ultimately, the relevancy of each of the six competencies for an individual designer is determined by the role this designer has in a company.@en

Today, citizens, professionals, civil servants, social enterprises, and others form different types of coalitions to overcome the challenges facing our modern cities. In this paper, the particularities of these types of groups are characterised and categorised into ten different types of city makers. Generally, these types of city makers bring value to cities, but we conclude that this value could be enriched through more participatory approaches that stimulate crossovers and accelerate the transition towards sustainable futures. Therefore, we characterise the different identified types as potential ‘participatory’ city makers. However, these participatory approaches and the networks between them still need to be developed, while improving conditions and dynamics that can enable and enhance innovation in urban environments. Design and systems thinking could contribute valuable methods and perspectives to the development of these participatory and systemic approaches. Finally, the categorisation presented in this paper must enable a better understanding of the transformative capacity of these different types of city makers, necessary for flourishing and sustainable communities.@en

Citizens and urban policy makers are experimenting with collaborative ways to tackle wicked urban issues, such as today’s sustainability challenges. In this article, we consider one particular way of collaboration in an experimental setting: Urban Living Labs (ULLs). ULLs are understood as spatially embedded sites for the co-creation of knowledge and solutions by conducting local experiments. As such, ULLs are supposed to offer an arena for reflexive, adaptive, and multi-actor learning environments, where new practices of self-organization and novel (infra-) structures can be tested within their real-world context. Yet, it remains understudied how the co-creation of knowledge and practices actually takes place within ULLs, and how co-creation unfolds their impacts. Hence, this paper focuses on co-creation dynamics in urban living labs, its associated learning and knowledge generation, and how these possibly contribute to urban sustainability transitions. We analyzed empirical data from a series of in-depth interviews and were
actively involved with ULLs in the Rotterdam-The Hague region in the Netherlands. Our findings show five distinct types of co-creation elements that relate to specific dynamics of participation, facilitation, and organization. We conclude with a discussion on the ambivalent role of contextualized knowledge and the implications for sustainability transitions.@en

This article aims to unravel the tensions that obstruct participatory city making: the processes in which government, entrepreneurs and citizens co-create new solutions for urban challenges. Participatory city making is explored and conceptualized through an empirical grounded study of local civil servants and citizen initiatives in Rotterdam. Through interviews and a set of three workshops the practices of these city makers are studied. A need for more transparency, influence and exchange was identified. The value of design is explored in general, and specifically the design of possible tools and interventions, to address the identified issues and tensions. This exploration shows that design-enabled interventions could, on the one hand, by 'infrastructuring', anticipate on the diffused design activities of individual actors in the urban context, and on the other hand, the use of these tools and interventions could promote participatory approaches among the different city makers towards urban sustainability transitions.

Co-creation for sustainable products and actions is a new approach to most of Vietnamese enterprises and consumers. The co-design workshop between companies and customers is an innovative way to bring them together, create mutual understanding and put the spotlight on sustainability. Through the GetGreen Vietnam project promoting sustainable living and working for Vietnamese middle-income consumers, we have seen the impacts and benefits of the co-design workshop on both the companies and the consumers. For example, the change in packaging design of Viet Lien tea product as a result of the co-design workshop has brought to waste reduction. This “Co-design of Sustainable Food in Vietnam” booklet is written for everyone, especially companies, consumers and experts, who want to organize a co-design workshop in Vietnam, with focus on food and sustainability. It includes the methodology, a step-by-step facilitation manual and the results of implemented co-design workshops. We hope that readers will be equipped with enough knowledge and be inspired to conduct more and more co-creation activities.@en

Growing unsustainable consumption in Vietnam is a pressing issue, especially in urban areas. The effects of rapid economic growth, industrialization and increasing wealth in combination with a young, growing population makes that the middle class of Vietnam is on the rise. This movement within the population is making room to form and introduce new consumption patterns; patterns that are both sustainable as well as adapted to the improving living standards. This thesis points out that food is the most promising category to start building these new consumption patterns from. In Vietnam both consumers and producers are looking for ways to make their practices sustainable. Design can help building and giving form to new behaviour patterns, products and services. However, creating more trust and understanding between the Vietnamese food consumers and producers is essential. Co-design specifically could enable the creation of trust and understanding as well as create a learning environment; ultimately leading to a better adapted, more attractive and sustainable food system in Vietnam.@en
