Sustainable Entrepreneurship : The impact of motivation, prior knowledge and network on sustainable business opportunity recognition

Voutilainen, Essi, Grabe, Lara January 2023 (has links)
This research aimed to create more knowledge and understanding of the opportunity recognition process for sustainable entrepreneurs in Nordic countries. By validating the two factors proposed by Patzelt and Shepherd’s (2011) model, prior knowledge and motivation, and examining the role of new factors such as networks, co-founders’ knowledge, and regulations, the authors contributed to a better understanding of how sustainable opportunity recognition works in practice. The findings show that a combination of different types of prior knowledge and altruistic motivations towards the environment plays an essential part in this process. Moreover, networks are a crucial factor in providing entrepreneurs with access to new knowledge and information that can lead to higher changes in sustainable opportunity recognition. Besides adding the factor of networks, this study identified other important factors, such as co-founders’ knowledge and regulations. By considering these factors, it is possible to understand better the sustainable opportunity recognition process of entrepreneurs.

Would you like your receipt? : Sustainability perspectives of consumer paper receipts

Sarenmalm, Isabel January 2016 (has links)
This report researches and analyses the sustainability perspectives of paper receipts, focusing on the economical, environmental and social aspects using a qualitative research method and by simultaneously drawing inspiration from the Sustainability Impact Assessment (SIA) model. The result section is conducted by using a literature review where a combination of previously used sources within my masters program is analysed and by reviewing articles and statistics in the search engine at the Uppsala University e-library database. The overall research purpose, to assess the sustainability of consumer receipts, is achieved by using the concept of sustainable development as the theoretical framework. This report suggests that there are some sustainability concerns with the current consumption of the traditional paper receipt, mainly in the context of environmental and social considerations. Three different alternatives to the traditional paper receipt are furthermore discussed as examples of potential routes forward. Two of the alternatives, electronic receipts and introducing a charge on paper receipts, are arguably the two most sustainable alternatives to regular paper receipts. The third alternative cannot be perceived as equally sustainable since “BPA/Bisphenol-free” receipts contain other chemicals equivalently hazardous to humans and the environment.

Assessing the performance of combined sustainable drainage and ground source heat devices in a domestic building

Faraj, A. January 2013 (has links)
A field study of the feasibility and the performance of a sustainable drainage technique combined with a renewable energy device to provide heating in a domestic setting was carried out from March 2008 to November 2010 to acquire practical data about the system’s operation. Among all the sustainable drainage techniques, permeable pavement system (PPS) was selected to be applied in this project since this particular technique can be used for driveways and car-parking hard standings, but more specially they can be designed as a tanked system whereby an impermeable membrane is installed at the bottom of the tank in order to hold the rainwater collected as runoff from hard areas and roofs before releasing it in a controlled manner. The renewable energy device applied in this study is a ground source heat pump system (GSHP), which has been found in previous studies to provide a better performance when installed in wet conditions. Based on this, the PPS and the GSHP with horizontal ground heat exchanger (GHE) were integrated in a 350mm deep reservoir under ‘real life’ conditins. The combined system operated in heating mode in a family–sized, three bedrooms detached EcoHouse at the Building Research Establishment Innovation Park, Watford, UK. Monitoring the combined system included taking measurements of the temperature of the conditioned space, the ground around the PPS/GSHP system, and of the ambient air every 10 minutes. Assessing the performance of the PPS/GSHP system involved investigating the effect of extracting heat via the GHE on the ground temperature, the impact of the PPS/GSHP on the thermal profile of the air above the surface of the reservoir, and computing the PPS/GSHP coefficient of performance (CoP). The thesis includes information about the design of the PPS/GSHP system including the structure of the sub-base, types and size of the used aggregate and stone, the depth of the excavated reservoir amongst others, also the technical problems that materialized, largely due to the fact that the PPS/GSHP was installed and operating under real-life circumstances. Results obtained from the study provided evidence for the workability of the combined system in regards of stormwater management and of providing heat to the EcoHouse. However, monitoring the rainwater stored in the reservoir showed that, due to leakage, the top part of the buried coil was not covered with water. The monitoring also revealed that the rainwater surrounding parts of the coil was, in severe weather, frozen. Moreover, highly significant correlations (p<0.01) were calculated for the ambient air and the ground temperature relationships with the CoP. All of these factors resulted in a 1.8 coefficient of performance being obtained. This low figure was related to the shallow depth of the reservoir since it became clear that its ground temperature was greatly influenced by the ambient air temperature. The study also revealed that the evaporation process was prevented from occurring due to the Inbitex™ composite layer, as a result there was no significant effect on cooling the thermal profile of the air near the surface of the pavement. Furthermore, it was concluded that continuous heat extraction from the ground contributed to an underground temperature drop.

Extra-curricular education for sustainable development interventions in higher education

Lipscombe, Bryan Paul January 2009 (has links)
Universities are seen to have a central role in the UN Decade of Education for Sustainable Development (ESD), partly through their teaching and research activities. However, the critique of Higher Education's (HE) contribution to sustainable development thus far points to the limitations of a discipline driven, curriculum content and solely student focused response. Within this context, extra-curricular interventions, for example, running awareness campaigns, creating groups and organising events, appear to have potential to advance ESD in HE. However, there has been little investigation or published work in this area. Ideas of non formal and informal education; constructivist theories of learning; concepts of free choice, tacit and social learning, and the notions of whole systems thinking and sustainable education all point to roles for interventions in the extra-curricular sphere. This thesis explores the use of extra-curricular interventions in HE through an empirical investigation in the UK. A 2006 postal survey of Higher Education Institutions (HEIs) records the extent and type of interventions in use and opinions about their utility. A case study, developed through action research, reports the use and impact of extra-curricular ESD-related interventions at one HEI over an academic year (2006-07). In this case study, regular contact with a group of staff and students over the year is used to map changes in their thoughts and actions relating to sustainable development, and to record the influences attributed to these changes. Importantly, extra-curricular ESD-related interventions are found to be commonly used in UK HE, and to have a prominent position in ESD work despite their limited visibility in the literature. Their utility is confirmed as they are seen to provide experiences that contribute to student and staff learning, as well as institutional change. The evidence collected supports their roles as: disciplinary bridge', community bridge; socialisation scaffold, and social learning arena. They appear to have a useful developmental role in mobilising and motivating members of the campus community. As peripheral activities, however, extra-curricular interventions may be prone to erratic implementation through being under-resourced. They can extend participation in BSD although will not reach everyone. They are best viewed as a complementary part of BSD and linked to a process of curricular and pedagogic renewal. In addition to confirming the extent, utility and limitations of extra-curricular ESD practice, the research contributes a model to map understandings of sustainable development. This model points to a core environmental understanding to which extra layers and strands of thinking can be added. It also confirms the importance of non formal and informal influences in shaping people's conceptions of sustainable development.

Chasing Responsible Sourcing: The case of UK retailers and sustainable seafood

Chironna, Serena January 2016 (has links)
Responsible Sourcing is gaining growing importance for companies willing to demonstrate responsibility and commitment to sustainable practices. Sourcing is a key element of supply chain management and by adopting responsible sourcing practices, companies can greatly contribute to the sustainability of their entire supply chains. Being close to both customers and suppliers, retailers hold a particularly influential position in the supply chain and their sourcing choices can play a key role for sustainability improvements. This paper investigates the different strategies that can be adopted to guarantee responsible sourcing in the retail sector, through the specific case study of two UK retailers, Sainsbury´s and Tesco, and their offer of sustainable seafood. Specifically, the relation between the offer of MSC certified products and the retailers´ commitment to source responsibly is here analysed. The main source of data collection is a content analysis of retailers´ CSR online reports and web pages. Additional information is obtained through reports and web pages’ analysis of four UK organizations dealing with sustainable seafood issues. The findings of the study suggest that the offer of MSC certified products is positively correlated with the adoption of responsible sourcing practices; different strategies are available to retailers to guarantee responsible sourcing and that retailers´ sourcing policies can be influenced by other stakeholders´ guidelines for responsible sourcing.

Sustainable housing futures for a growing middle class : a contextual study of Mysore, India

Basavapatna Kumaraswamy, Satish January 2014 (has links)
Economic globalisation is enabling India to reinvent itself as a development crucible, providing previously unrealised opportunities for economic transformation. One crucial transformation of economic success is the rapidly growing middle class. Whilst the growth in the middle classes indicates improvement in the quality of life of many, the rate of consumption has also been increasing exponentially. If they, the middle classes consume resources at the same rate as the British and Americans, India will become the world’s number one producer of carbon emissions. The attitudes and aspirations of the growing middle classes are a major factor in the increased, and perhaps impulsive consumption patterns. It is therefore the aim of this research to consider the bottom-up approach, which validates this thesis by examining middle class homeowners’ preferences in Mysore, a south Indian city. Mysore used to be recognised as having socially cohesive and inclusive housing typologies that were climate responsive and calibrated to local, social and economic needs. Changes in social conditions, cultural practices and lifestyle can be seen in the way homeowners use their homes to demonstrate affluence and status. A key challenge is to research ways in which sustainable housing in an Indian context can both mitigate carbon emissions and at the same time address the material aspirations and desires of a fast-growing middle class. Baseline characteristics and homeowners’ attitudes are established by means of literature research and fieldwork. The output of this stage is triangulated with further research to narrow the focus towards boundary conditions and transition spaces for an in-depth study of relevant factors contributing towards consumption, aspiration and sustainability. The second stage points to the importance of the external boundary of the site and the edge of buildings in terms of aligning meaningful, sustainable design strategies with the concerns and aspirations of the emergent middle-class. This thesis argues that, in the domain of sustainable housing, both a qualitative approach and quantitative strategies are essential to the understanding of social and cultural dynamics as well as to measure and benchmark performance. Because of the nature of this multi-threaded approach, mixed method research practices have been followed using triangulation methodologies and grounded theory. This has resulted in the revisiting and refining of the research focus and objectives throughout the research. During the research process, spatial scenarios for housing were developed to harmonise preferences and different sustainability agendas. The research focused on identifying and testing the critical building characteristics of the boundary location. Homeowners’ preferences were qualified by a multi-sorting task analysis and study model performance tested by sophisticated environmental simulation. This was triangulated with fieldwork studies to help propose sustainable housing strategies. The methodology adopted has been critical to supporting the architectural response to the cultural and economic condition on one hand (social methods) and the climate responsive, traditional design and simulation models (environmental design methods) on the other. Different sets of fieldwork were conducted at two stages that involved archival searches and detailed interaction with architects, builders, users, academics and government agencies. In total, 240 respondents answered a questionnaire survey and 146 semi-structured interviews were conducted. The outcome of this research demonstrates how, in the absence of any counterbalancing regulations, social perception and economic aspirations limit the acceptability of sustainable design and construction strategies. In India, middle class demographics and value systems are complex; where safety and security, and display of wealth have to go hand in hand. In this context, this research provides new insight into the way sustainability can be understood in the Indian context with qualitative values that are complemented by quantitative measurements. Finally, this research suggests ways of introducing sustainable practices through a negotiated understanding that balances aspirations with more responsive design. India has identified housing as one of the eight national missions to reduce carbon emissions as part of its commitment to reduce people’s vulnerability to the impact of climate change. In a geo-climatically, regionally and culturally diverse country like India, the top-down national policy can only be successfully implemented with an understanding of the local context. A bottom-up approach to identify sustainable strategies that acknowledge homeowners needs and aspirations should be a useful contribution to achieving carbon reduction and sustainable housing in Mysore. With minor adjustments, the methodology and research process could be adopted in other Indian cities.

Are there inherent contradictions in attempting to implement education for sustainable development in schools?

Vare, Paul January 2014 (has links)
Despite being ranked according to narrow measures of pupil achievement, many schools aim to become more sustainable. Faced with indicators suggesting the rapid degradation of social-ecological systems, these schools would prefer not to be part of the problem. However, environmental education/education for sustainable development (EE/ESD) in schools does not reflect the transformative rhetoric of academic discourse. Research into this ‘rhetoric-reality gap’ has focused either on academic discourse or the psychology of individual teachers; there is a lack of critical research on teachers-in-context. This enquiry explores the notion of inherent contradictions in developing a sustainable school (however subjects define this). It applies an Activity Theory framework designed to identify contradictions within ‘activity systems’ (e.g. schools). The primary method is a semi-structured interview conducted with fifteen teachers/headteachers in twelve schools (primary and secondary). The thesis offers a resource-efficient qualitative interview process that can bring Activity Theory to school-based research with minimum disruption and outlines a streamlined process of dilemma analysis. The data highlights contradictions in the way that schools conduct EE/ESD noting that these are often not recognised by educators themselves. Five different responses to contradictions are identified, including ‘expansive learning’ that redefines the activity itself. In terms of an ESD1/ESD2 framework, this might be termed ‘ESD 3’. Four approaches that schools may adopt in relation to sustainability are also outlined. An empowering vision of schools – and society – as autopoietic systems, i.e. as both products and producers, suggests that social reality is not as inevitable as it seems. By confronting contradictions, educators demonstrate the adaptive capacity required by young people if they are to engage in remodelling their world. Finally, the thesis proposes combining a two-sided conception of ESD with Activity Theory, potentially to the mutual benefit of both. Investigating this further is one of a number of options for further research.

Planning for sustainable urban water: systems-approaches and distributed strategies.

Fane, Simon Anthony January 2005 (has links)
This thesis develops and applies a number of methods for systems analysis and assessment within the field of sustainable urban water. These focus on the evaluation of distributed strategies. In line with arguments made within the thesis, the methods developed assess urban water on a whole-system basis, with the system defined in terms of the services provided. Further, the thesis argues for sustainable urban water planning to take a pluralist stance; both in the conception of sustainable urban water and the strategies considered. The challenges of sustainability and sustainable development are fundamentally problems of complex systems. Planning and assessment of sustainable urban water therefore require a systems-approach. Systems-thinking is not, however, a unified body of knowledge and this thesis develops a unique perspective on systems-thinking which is used to critically review the fields of sustainable urban water and its assessment. Within these reviews, the thesis develops a framework for understanding sustainable urban water in terms of a number of varied approaches, and describes a feasible theoretical basis for assessing sustainable urban water. Many, so called, sustainable strategies are small-scale and distributed in nature. Distributed strategies include decentralised systems, embedded technologies, and local measures for conservation. Traditional systems analysis methods have failed to account for distributed strategies. To adequately include distributed strategies, this thesis argues that assessment methods will need to be based on whole-system modelling, utilise end-use models of service provision, and include - in the form of a demand forecast - a time dimension in relation to service provision. This thesis proposes new methods for microbial risk assessment on a whole-system basis and Least cost planning for (urban water) Sustainable Scenarios (LeSS). A novel evaluation framework for least cost planning for water supply, which provides an equivalent comparison of demand- and supply-side options, is also developed. These methods are illustrated through case studies. These case studies illustrate the potential of distributed strategies. When assessed on an equivalent basis, in various examples, distributed strategies are shown to be particularly cost effective. Decentralised wastewater reuse systems are also shown to impose a theoretically lower level of pathogen risk on the community than equivalent centralised reuse schemes. Despite the advances in assessment methodologies made within the thesis, further development of practical tools for assessing and planning sustainable urban water remains an urgent goal.

Community Foundations: The Asset-based Development of an Australian Community Organisation as a Foundational Source for Sustainable Community Development.

Bryant, Sharon, mindstream@optusnet.com.au January 2007 (has links)
This study seeks to uncover the opportunities and challenges in building the foundations for sustainable community development at the local level, by enhancing the capacity of a community organisation. Challenging the traditional needs-based focus of community development, the research builds from the work of Kretzmann and McKnight by applying an asset-based approach to both community development and capacity building of community organisations. This study thus shifts the focus of community development away from its traditional application on
