The transition from one energy system to another has been analysed by many researchers especially in the context of developed countries. Community renewable energy transition in rural areas is largely under-researched, particularly in developing countries. This study developed a model based on indicators from transition theory and concepts to assess the transformative potential of the processes and governance approaches to community renewable energy in accelerating energy and sustainability transition in off-grid communities in Nigeria. The exploratory research adopted a case study approach and analysed renewable energy planning and decision-making processes as well as evaluated the development of a pilot community renewable energy project in Shape rural community in Nigeria. In addition to documentary evidence, the study gathered data primarily by interviewing 24 relevant actors in the Nigerian electricity industry as well as actors involved in the pilot community renewable energy project. The study reveals that the processes and governance approaches adopted are in line with transition theory and have the potential of contributing to the transformation of the rural electricity provision in Nigeria. However, there is still a long way to go for Nigeria to effectively implement an integrated governance approach capable of accelerating the transition processes. The study found that community renewable energy is motivated by several determinants including: the lack of energy accessibility; removing carbon emissions; meeting environmental obligations; achieving energy security; and, addressing cracks in the current system of rural electrification. The study further found a lack of local initiatives at the grassroots level that can add pressure to make the transition happen. The study found the establishment of an arena for the identification of the challenges facing rural communities and development of strategies. However, some prominent actors are not involved in both strategic decision-making and the implementation process. Of concern, the study revealed a lack of clearly defined responsibilities with most of the government agencies carrying out renewable energy activities independently. Similarly, the study found several barriers which are classified as: actor; interaction; institutional; infrastructural; and, socio-political that are challenging the successful transition to community renewable energy. This work contributes to current attempts to operationalise transition theory and concepts to assess on-going transition processes and governance. This is a significant contribution to the literature because it helps in linking theoretical development with sustainability in practice in a developing country context. The study may assist policy makers, communities and other relevant stakeholders in designing an integrated governance framework for renewable energy transition in rural areas.

Urban areas will play a decisive role in the sustainability of future societies. As such, there is a need to understand the processes through which cities can become more sustainable. Based on a qualitative case study of a community food waste initiative in Gothenburg, Sweden, this thesis explores the phenomenon of urban sustainability transitions in relation to learning. The thesis attempts to explain how learning at the level of socio-technical niches could be instrumental to broader systemic changes at the regime level. The theoretical framework for the thesis draws on the transactional perspective on learning developed from pragmatist educational philosophy, as well as practice theoretical approaches to studying sustainability transitions which have emerged in recent years. The empirical results gathered from the case are analysed using dramaturgical analysis and practical epistemology analysis. Based on these analyses, the thesis argues that the role and significance of learning in urban sustainability transitions can be understood in terms of educative practices, a concept which is elaborated in the discussion chapter. Thus, it is argued that learning through educative practices can contribute to urban sustainability transitions by challenging prevailing institutional norms and structures, and by establishing pathways through which unsustainable elements within the socio-technical regime can be reconfigured. / Wicked Problems and Urban Sustainability Transition

Both the ecological and social system are systematically degrading, resulting in decreasing capacities to support human civilization. Product development and manufacturing companies play a key role in driving society’s transition towards a sustainable path. Besides moral arguments, the motivation for companies can be expressed as a matter of smart risk management, i.e. avoiding threats and exploiting opportunities. Such sustainability risks can be related to, for example, brand and reputation, legislative change, or attracting top-talented employees. But, more importantly, it is about understanding changes that are inevitable on markets to come. Based on Maxwell’s interactive qualitative research approach and following the structure of the Design Research Methodology, this thesis aims to contribute (i) to knowledge by increasing the conceptual understanding of what sustainability risks are; and (ii) to practice by researching decision-support for how sustainability risks can be managed in a product development company context. The first study reviewed existing literature and identified characteristics of sustainability risks, which make them particularly difficult to manage. A following exploratory and descriptive study investigated companies’ current risk management practices and preconditions for sustainability integration. It showed that the effects of uncertainty from the sustainability transition need to be identified, assessed, and managed in relation to how they can affect objectives anchored in both internal and external stakeholder value creation. In parallel, the Framework for Strategic Sustainable Development was applied as a lens to understand the implications of the sustainability transition for company risk management. This resulted in a new definition, stating that sustainability risks are threats and opportunities that are due to an organization’s contribution or counteraction to society’s transition towards strategic sustainable development. A questionnaire study then investigated some case companies’ challenges and preconditions to build sustainability capabilities. Finally, a workshop method is proposed that aims to support design teams in early sustainable product development. Future research will leverage on the findings to develop and test decision support for how product development companies can manage sustainability risks on different organizational levels in practice to increase competitiveness, while taking leadership in the transition towards a sustainable society.

Background:  Entering a new geological epoch where humans are the main force shaping of the biosphere, have forced an immense stress onto society and the Planet with regards to sustainability. The United Nations and the Paris Agreement have strongly emphasized the urgent need to allocate finance onto urgently mitigating climate change. The financial sector has confronted this challenge through providing sources of finance to meet sustainability requirements. Thus, green bonds emerge as an instrument aimed to cooperate in the transition towards advancing sustainability.    Purpose: Given the ambiguity of green bonds impacts on environmental sustainability, this study explores the contributions of green bonds towards a fruitful transition towards sustainability. Being crucial stakeholders in the transition towards sustainability, these contributions have been examined in the context of Swedish municipalities    Method: To examine the contributions of green bonds in the given context, an exploratory research was conducted using a multiple case study design. Five municipalities, two investors and a municipal funding agency were interviewed though semi-structured interviews. A thematic analysis was performed on the empirical data. First, a within-in case analysis was conducted following a cross-case analysis allowing to find emergent and common patterns.   Conclusion: The green financial instrument does not appear to be a main driver of sustainability, nor does it have a significant influence on the environmental impact of the municipalities’ investment projects. Nevertheless, the study finds that green bonds contribute to advancing sustainability in municipalities through three main areas: Financial impetus, organizational effects and structure and requirements. Thus, the municipalities studied provide evidence that green bonds grant a small reduction in the cost of capital, produce organizational effects like increasing collaboration between the environmental and financial department and enhances transparency through its structure and requirements.

The topic of Impact Investing has been creating waves and generating a lot of interest in the funding ecosystem with the growth of impact startups & because of pressure from the populace in the face of global challenges. At the same time the field has been under-explored by scholars. The exploration of the investment industry is performed by collecting investors' perspective on the self defined concept of Impact investing. The research attempts to portray the perspective of the established Venture Capital regime on Impact Investment and understand whether it is still perceived as philanthropic endeavors investing in an alternative asset class, suggested by previous academic research or an industry wide transition and change of investment practices as portrayed by the industry research. This study is focused on the Swedish & U.S. Venture Capital regimes. Sweden, a country that has been described as the “Impact Capital”, and the U.S. that represents worlds largest VC capital sector. Semi-structured qualitative interviews were used in this study to explore the industry dynamics using a MLP(Multi Level Perspective) framework. The interviews with VCs help understand the current sentiment on the growth in impact investing and why the Swedish market is seeing an industry-wide transition while the U.S. VC’s treat it as a separate asset class.  The authors identified that the U.S. regime is currently in the emergence phase of transition while the Swedish regime has reached the transformation phase. Additionally four key themes that differentiate the perspective of the Swedish and US regimes were identified; Risk, Profitability, Use-Case & Branding. / Impact Investing är ett ämne som har skapat vågor och genererat ett stort intresse för finansieringsekosystemet i samband med tillväxten av nystartade företag och påtryckningar från befolkningen inför de globala utmaningarna. Trots det har ämnet sett begränsad akademisk forskning. Explorationen av investeringsbranschen utförs genom att samla investerarnas perspektiv på det självdefinierade konceptet Impact Investing. Forskningen försöker skildra hur den etablerade riskkapitalregimen ser på Impact Investment och förstå om det fortfarande uppfattas som filantropiska initiativ av att investera i en alternativ tillgångskategori, som föreslås av tidigare akademisk forskning eller en branschomfattande övergång och förändring av investeringspraxis som framställts av industriforskningen.  Denna studie fokuserar på riskkapitalsregiment i Sverige och Amerika. Sverige, ett land som har beskrivits som "Impact Capital", och USA som representerar världens största VC-kapitalsektor. Semistrukturerade kvalitativa intervjuer används i denna studie för att utforska industridynamiken med hjälp av MLP(Multi Level Perspective)-ramverket. Intervjuerna med riskkapitalister hjälper till att förstå den nuvarande uppfattningen om tillväxten av impact investment och varför den svenska marknaden ser en branschomfattande förändringsprocess medan amerikanska VC:s behandlar det som en separat tillgångskategori. Författarna identifierade att den amerikanska regimen för närvarande befinner sig i begynnelsefasen medan den svenska regimen har nått transformationsfasen. Dessutom identifierades fyra nyckelteman som skiljer de svenska och amerikanska regimernas perspektiv; Risk, Lönsamhet, användningsfall & varumärke.

Sustainability has been considered a novel research field emerging from the desire to protect the environment, and equally emerging in transition discourses. This research explores the construction of sustainability transition processes and pathways in a public sector organization implementing a sustainability oriented program. The study takes on an explorative, qualitative longitudinal approach. Through antenarrative inquiry, analysis is made on the stories and discussions as a reflexive way in expressing experiences and by giving meaning to these experiences. Assessed within sustainability transition theories, processes and pathways emerge from socio-technical transitions and its micro-foundations. Results indicate that pathways of transition exist in socio-technical systems, socio-political systems, socio-institutional systems and in socio-ecological systems as achored in public sector processes. The narrative character and sustainability formations potray inclusivity of actors, continuity and gradual transition processes. It is therefore opined that  sustainability oriented programs and projects implemented in developing nations by the public sector have the ability to enable niche level changes by creating necessary momentum at the micro-foundations required to distabilize dominant regimes. Methodoligally, antenarratives provide an avenue for prospective sensemaking necessary in prospected and wholistic sustainability transitions.

As a purposive sustainability transition requires environmental innovation and innovation policy, we discuss potentials and limitations of three dominant strands of literature in this field, namely the multi-level perspective on socio-technical transitions (MLP), the innovation systems approach (IS), and the long-wave theory of techno-economic paradigm shifts (LWT). All three are epistemologically rooted in an evolutionary understanding of socio-technical change. While these approaches are appropriate to understand market-driven processes of change, they may be deficient as analytical tools for exploring and designing processes of purposive societal transformation. In particular, we argue that the evolutionary mechanism of selection is the key to introducing the strong directionality required for purposive transformative change. In all three innovation theories, we find that the prime selection environment is constituted by the market and, thus, normative societal goals like sustainability are sidelined. Consequently, selection is depoliticised and neither strong directionality nor incumbent regime destabilisation are societally steered. Finally, we offer an analytical framework that builds upon a more political conception of selection and retention and calls for new political institutions to make normatively guided selections. Institutions for transformative innovation need to improve the capacities of complex societies to make binding decisions in politically contested fields.

Cities in the Global South are undergoing rapid urbanization, where a high percentage of the urban poor live in informal settlements that lack basic services, are associated with unemployment, low-income levels, and insecurity. The impacts of climate change, intensive agricultural practices, and highly globalized food systems pose challenges to food security. Urban farming is one of the alternative practices to tackle food insecurity and urban poverty. In this study, urban farming was examined through grassroots innovation theory, which focuses on creating innovative sustainable development solutions from the bottom up. However, insufficient research has been done on urban farming initiatives in highly deprived areas. A qualitative approach was adopted, where semi-structured interviews were conducted, that were triangulated with observation and documentation data, providing multiple sources of support. The data was analysed through the Resources-Rationales-Relations Framework, which has been also used by other researchers to analyse grassroots initiatives. The results demonstrate that water is a crucial resource in urban farming grassroots initiatives, as water availability is limited due to droughts and climate change. Furthermore, resource-scarce environments experience limited access to water due to the unequal distribution of resources. Another identified resource that urban farming grassroots initiatives imply is climate-smart innovative technologies, such as the hydroponic system, that gives farmers good exposure. Sustainable livelihood creation was the main rationale to be involved in urban farming grassroots initiatives, by creating employment, giving back to the community, and influencing youth’s food and lifestyle choices. Relations were found to be crucial between farmers and organizational intermediaries, as they have increased their visibility and enabled them to engage with a wider context. The study concludes that the urban sustainability transition in Global South’s informal settlements is achieved when it cuts through all three levels of knowledge production, which was done by the climate-smart innovative farming technologies that raise attention and interest beyond the local context up to the political arena.

Rechargeable batteries are set to power sustainable development by 2030. In this context, the increasingly important role of certain ‘strategic minerals’ used in emerging renewable technologies has become highly topical. As the geopolitical landscape is changing as the world moves away from fossil fuels, a surge in demand for these minerals will entail an increase of production at unprecedented levels. A case in point and a focus of analysis in this thesis is the extractive sector sourcing one of the most important of transition minerals ‘cobalt’ that is predominantly mined in the Democratic Republic of the Congo (DRC). Against the challenge of a secret and non-transparent mining industry, this thesis has identified and listed all operational and openly communicative Multinational Corporations (MNC’s) extracting cobalt in the DRC. By conducting a critical discourse analysis on seven different cobalt extracting MNC’s, the analysis unveils different ways in which the companies ‘frame’ cobalt as strategic. Thus, a new and relevant ‘material-discursive framework’ has been utilised to bridge the underlying discourses of these companies with their material practices relating to cobalt. By employing this theoretical framework, the findings point at three main logics of corporate narrative the MNC’s in the sample use to form and maintain their operational activities: securitisation, environmentalism and developmentalism. Central discourses within these themes point at the way in which companies seek to maintain their economic security and legitimacy in an increasingly contested industry by continuously representing themselves as central actors with the responsibility and knowledge to deliver sustainable development for local communities affected by the industry in the DRC and for the sustainability transition.
