The research is framed on the premise that designing buildings that can adapt by accommodating change easier and more cost-effectively provides an effective means to a desired end a more sustainable built environment. In this context, adaptability can be viewed as a means to decrease the amount of new construction (reduce), (re)activate underused or vacant building stock (reuse) and enhance disassembly/ deconstruction of components (reuse, recycle) - prolonging the useful life of buildings (reduce, reuse, recycle). The aim of the research is to gain a holistic overview of the concept of adaptability in the construction industry and provide an improved framework to design for, deploy and implement adaptability. An over-arching research question was posited to guide the inquiry: how can architects understand, communicate, design for and test the concept of adaptability in the context of the design process? The research followed Dubois and Gadde s (2002) systematic combining as an over-arching approach that continuously moves between the empirical world and theoretical models allowing the co-evolution of data collection and theory from the beginning as part of a non-linear process with the objective of matching theory with reality. An initial framework was abducted from a preliminary collection of data from which a set of mixed research methods was deployed to explore adaptability (interviews, building case studies, dependency structural matrices, practitioner surveys and workshop). Emergent from the data is an expanded and revised theory on designing for adaptability consisting of concepts, models and propositions. The models illustrate many of the casual links between the physical design structure of the building (e.g. plan depth, storey height) and the soft contingencies of a messy design/construction/occupation process (e.g. procurement route, funding methods, stakeholder mindsets). In an effort to enhance building adaptability, the abducted propositions suggest a shift in the way the industry values buildings and conducts aspects of the design process and how designer s approach designing for adaptability.

Today there is a lack of official environmental labels for mobile phones. In addition, at the moment it does not necessarily mean that a product is more sustainable because it is marketed as green or as environmentally friendly. It has to be easier for consumers to evaluate and pit “green” products against each other, as well as create a picture of which model is the most environmentally adopted and within which issues the biggest environmental benefits lay. The aim of this study is to analyse a selection of smartphones, which are sold by TDC SE, through a lifecycle perspective. The selection will be limited to the major suppliers and their most commonly sold phones by TDC. The purpose of the analysis is to classify the selected models based on their environmental and social impacts in their different lifecycle stages, and to present the results to the customers so they can consider that in their decisions. The following models were assessed in the study: iPhone 5s, iPhone 6 and iPhone 6s from Apple; Lumia 550, Lumia 650 and Lumia 950 from Microsoft; Galaxy A3 2016, Galaxy Xcover3 and Galaxy S6 from Samsung; as well as Xperia Z5, Xperia M4 Aqua and Xperia M5 from Sony. The study has developed a tool for analysing and characterizing the Smartphones’ sustainability performance. Several sustainability categories was developed, which each consists of a set of sustainability criterions, in order to analyse the models sustainability performances. The analysis has considered key issues, problem areas and impacts reading the smartphones sustainability performance. The characterization applies a scoring system in regards to how the models perform within the selected criteria compared to the industry’s average performance level (representing industry standard) as well as best practice examples. The assessed sustainability criterions are then additionally analysed through a multi-criteria analysis (MCA). In the MCA the criterions relevance are weighted and combined to an overall sustainability score of the models performance in each category. The study also examines the possibility for consumers to weight the different sustainability categories into an overall sustainability score for each model. This enable the customers to rank the models sustainability performance based on their preference (which categories that is more or less important to them). Regarding the models characterised sustainability performance it is clear that Samsung Galaxy S6 overall performs the highest of the studied models. In addition, all the Samsung models preformed high in general (except that Galaxy Xcover3 and A3 preformed the lowest of all the models in regards to environmentally preferable alternatives). Microsoft generally performed quite high and especially high in regards to life prolonging features and the use phase (were Lumia 950 scored especially high). Although, Microsoft performed quite low in regards to environmentally preferable alternatives as well as lifecycle thinking. Apple preformed high (scored higher than the other suppliers) in regards to environmentally preferable alternatives. However, in general Apple performed quite low, especially regarding life prolonging features and iPhone 5s also scored the lowest of all models in regards to substances of concern. Sony preformed very high in regards to I lifecycle thinking and the use phase and in general quite high in most categories (expect that the Xperia M5 model preformed among the lowest in regards to transportation). The result of the study has been highly affected by the degree of available information concerning the different models and suppliers. It is also interesting that models from different suppliers (with similar degree of available information) ranked differently relative to each other depending on the weighting (preference) between the different sustainability categories. Moreover, the study had to consider and find a balance between available information and desirable information. This mainly refers to the development and definition of industry standards and best practice levels. The study had to consider and decide what could be expected and measured/evaluated in regards to the independent demands, criticism and issues which the industry face. After concluding the study it is clear that the result has been greatly affected by the degree of available information for the studied models. It is also clear that today there is a great lack of model specific information and data. The study also found that it is important with feedback and follow-up communication with the suppliers, in order to correct misunderstandings and provide clarifications. In conclusion, the result of the study can be used as a decision basis for customers who wish to consider the smartphones’ sustainability performance is their choice. / Pris och funktion är fortfarande de avgörande faktorerna vid köp, men miljön håller mer och mer på att bli ett avgörande kriterium och intresset för ”grön” IT ökar. De officiella miljömärkningarna och oberoende granskningarna av elektronikföretag kan hjälpa konsumenter att göra bra val bland butikernas utbud. I Sverige finns det dock endast en officiell miljömörkning för mobiltelefoner, TCO certifieringen. Det blir dock mer och mer vanligt med eco-ratings, till exempel Eco Rating 2.0 och certifiering enligt UL 110 standarden för mobiltelefoner. Idag finns det alltså en brist på officiella miljömärkningar för mobiltelefoner och för tillfället så betyder det inte nödvändigtvis att en produkt är mer miljövänlig bara för att den marknadsförs som grön eller som miljöanpassad. Därför måste det bli enklare för konsumenter att utvärdera och ställa gröna produkter mot varandra samt att bilda sig en bild över vilken modell som tar mest hänsyn till miljön och inom vilka frågor som den största miljönyttan ligger. Målet med studien har varit att analysera ett urval av smartelefoner som säljs av TDC utifrån ett livscykelperspektiv. Urvalet har begränsats till de största leverantörerna och deras telefoner som vanligtvis säljs mest av TDC. Syftet med analysen har varit att klassificera de utvalda modellerna baserat på deras miljömässiga och sociala påverkan i deras olika livscykelfaser, samt att presentera resultatet till kunderna så de kan ta hänsyn till detta i deras val. De följande modellerna utvärderade i studien: iPhone 5s, iPhone 6 och iPhone 6s från Apple; Lumia 550, Lumia 650 och Lumia 950 från Microsoft; Galaxy A3 2016, Galaxy Xcover3 and Galaxy S6 from Samsung; samt Xperia Z5, Xperia M4 Aqua och Xperia M5 från Sony. Studien har utvecklat ett verktyg för att analysera och karakterisera smarttelefonernas hållbarhetsprestanda. Flera hållbarhetskategorier utvecklade och tog fram, som i sin tur består av ett flertal hållbarhetskriterier, för att kunna analysera modellernas hållbarhetsprestanda. Analysen har tagit hänsyn till nyckelfrågor, problemområden och påverkan rörande smarttelefonernas hållbarhetsprestanda. Hållbarhetskriterierna har valts ut baserat på informationen som samlats in i screeningen, käraktaren hos de data som erhållits från leverantörerna samt tillgängliga mått och möjligheten att utvärdera de valda kriterierna. I karakteriseringen så tillämpas ett betygsystem relaterat till hur modellerna presterar inom de vala kriterierna jämfört med industrins genomsnittliga prestationsnivå (representerar industristandard) och best praxis exempels. Där den högsta nivån innebär att hållbarhetskriteriet behandlas utöver industristandard (representerar best practice). Den mellersta nivån innebär att hållbarhetskriteriet behandlas på samma nivå som industristandarden. Och den lägsta nivån innebär att hållbarhetskriteriet inte finns tillgänglig för allmänheten. De utvärderade hållbarhetskriterierna blir sen ytterligare analyserade med hjälp av en Multi- kriterium analys (MCA), där kriterierna viktas baserats på deras relevans och kombineras till ett övergripande poäng av modellens prestation i varje kategori. Viktningen tar även hänsyn till hur (progressiv) svårt det är att uppnå best practice nivån jämfört med industristandarden samt att uppnå industristandarden. Studien undersöker även möjligheten för kunderna att vikta de olika hållbarhetskategorierna till ett övergripande poäng för varje modell. Detta görs för att kunna ranka modellernas hållbarhetsprestanda basrat på kundernas preferens (vilka kategoriers som är mer eller mindre viktiga för dem). <img src="file:///page6image25648" /> Baserat på modellernas karakteriserade hållbarhetsprestanda är det klart att Samsung Galaxy S6 på det hela taget presterade högst av alla de studerade modellerna. Alla Samsungs modeller presterar också generellt väldigt högt (bortsett från att Galaxy Xcover3 and A3 presterade lägst III av alla modeller med hänsyn till miljövänliga alternativ). Mikrosoft presterade generellt ganska högt och speciellt högt med hänseende till livsförlängande funktioner och användarfasen (där Lumia 950 presterade speciellt högt). Dock så presterade Microsoft ganska lågt inom miljövänliga alternativ samt livscykeltänkande. Apple presterade högt (fick högre poäng än de andra leverantörerna) inom miljövänliga alternativ. Dock så presterade Apple generellt ganska lågt, speciellt med hänsyn till livsförlängande funktioner och iPhone 5s presterade också lägst av alla modeller inom potentiellt farliga ämnen. Sony presterade väldigt högt med hänsyn till livscykeltänkande och användarfasen, samt ganska högt in de flesta kategorierna (förutom att Xperia M5 modellen presterade bland de lägst inom transporter). Studiens resultat har till stor del påverkats av de olika graderna av tillgänglig information för de olika modellerna. Det är också väldigt intressant att modeller från olika leverantörer (med liknande grad av tillgänglig information) rankades olika relaterat till varandra beroende på viktningen (preferensen) mellan de olika hållbarhetskategorierna. Studien har också till stor del behövt ta hänsyn till och hitta en balans mellan tillgänglig information och önskad information. Detta referera främst till framtagningen och definitionen av industristandards och best practice nivåerna. Studien har behövt betrakta och bestämma vad som kan förväntas, mätas och utvärderas relaterat till de oberoende krav, kritik och frågor som industrin står inför. Efter att studien slutförts är det klart att resultatet till stor del har påverkats av de olika graderna av tillgänglig information för de studerade modellerna. Det är även klart att der finns en stor brist på modellspecifik information för de studerade modellerna. Studien kom fram till att det är viktigt med återkoppling och uppföljande kommunikation med leverantörerna, för att rätta till missförstånd och tillhandahålla klargöranden. Avslutningsvis så kan studiens resultat användas som beslutsunderlagg för kunder som vill ta hänsyns till smarttelefonernas hållbarhetsprestanda i sitt val.

Problem: Idag påverkas företagen av tryck utifrån av sina intressenter vilket gör att de måste ta ett större ansvar för att legitimera sig. Olika branscher har varit med om olika skandaler och blivit uppmärksammade på olika sätt. Kan detta leda till att branscher utvecklas olika i sitt ansvarstagande för hållbarhet?Syfte: Syftet med studien är att undersöka om olika branscher i Sveriges näringsliv har utvecklats olika emot ett hållbart samhälle och därmed att beskriva hur långt deras ansvarsområden sträcker sig i årsredovisningar och hållbarhetsredovisningar. Mer specifikt undersöka branschernas ansvar inom ekonomi, miljö och socialt.Forskningsfråga: Vilka skillnader finns det mellan branschernas ansvarstagande inom hållbarhet idag?Forskningsdesign: För att besvara vår forskningsfråga använde vi oss av en kvalitativ innehållsanalys av företagens hållbarhetsrapporter och årsredovisningar. Vi utför en tvärsnittsstudie av tre branscher med tre företag i varje bransch. Branscherna är Textil-, livsmedel- och finansbranschen.Slutsatser: Sammanfattningsvis kan man se att det finns skillnader mellan branscherna. Textilbranschen visade på störst ansvar när man jämförde alla kategorier. Medan livsmedelsbranschen och finansbranschen visade på ett mindre ansvar i förhållande till textilbranschen. När vi sedan ser till varje kategori kan man urskilja var skillnaderna ligger. I den ekonomiska kategorin fanns en stor likhet och inga skillnader kunde identifieras. Inom kategorin för miljö visade textilbranschen ett betydligt större ansvar i förhållande till de övriga branscherna. Kategorin för det sociala ansvaret var betydligt mer omfattande och de olika branscherna utmärkte sig olika mycket i de olika underkategorierna. Inom alla underkategorier visade det sig att Livsmedelsbranschen tog ett mer jämnt ansvar. I anställningsförhållanden och arbetsvillkor utmärkte sig finansbranschen och vidare visade textilbranschen på ett stort ansvar inom mänskliga rättigheter. / Problem: Today’s businesses are affected by the pressure from the outside, by their stakeholders. This allows them to take greater responsibility for legitimacy. Different industries have been involved in various scandals and have received attention different ways. Could this lead to industries developing differently in their social responsibilities for sustainability?Purpose: The purpose of the study is to investigate whether various industries of the Swedish economy has developed differently to a sustainable society and thus to describe how far their responsibilities extend in annual reports and sustainability reports. More specifically investigate various industries responsibilities in regards to economic, environmental and social aspects.Research question: What differences exist between the industries' responsibility in sustainability today?Research Design: To answer our research question, we used a qualitative content analysis of corporate sustainability reports and annual reports. We carry out a cross-sectional study of three industries with three companies in each industry. The industries are textile, food and the finance industry.Conclusions: In summary, one can see that there are differences between industries in the whole. The textile industry showed the greatest responsibility when comparing all the categories. While the food industry and the financial industry showed a minor responsibility in relation to the textile industry. When you look at each category we can distinguish where the differences lie. In the economic category, there was a great similarity and no differences could be identified. Within the category of environment the textile industry showed a much greater responsibility in relation to the other industries. The category of social responsibility was much more extensive and the various industries stood out very different in the different subcategories. In all subcategories, it turned out that the food industry took a more evenly responsibility. In terms of employment and working conditions distinguished the financial industry and the textile industry showed great responsibility in human rights.

Fillers are often incorporated in polymer matrices in order to improve cost, mechanical, thermal, and transport properties. This work explores the hypothesis that pollen, a natural particle, has the potential to be an effective biorenewable reinforcing filler due to its unique surface architectures, high strength, chemical stability, and low density. Pollens from sources such as ragweed plants are ubiquitous natural materials that are based on sustainable, non-food resources. Pollen is a remarkable example of evolutionary-optimized microscale particle with structures and/or chemistries tailored for effective adhesion to a variety of surfaces and protection of genetic material under different dynamic and environmental conditions. The pollen shell is perhaps the most chemically resistant naturally occurring material. As many pollens achieve pollination simply by being carried by wind, they are very light-weight. These properties make pollen an attractive option as a natural filler for polymers. This research aims to characterize pollen interfacial properties and utilize pollen as an effective reinforcing filler in polymer materials. In this work, interfacial properties are characterized using Fourier transform infrared spectroscopy (FTIR), the BET method, and inverse liquid chromatography (ILC). These techniques were useful in determining the effect of surface treatments and further chemical modifications on pollen interfacial properties. Characterizing these properties allowed for improved understanding and utilization of pollen as a filler by revealing the enhanced surface interactions and surface properties of acid-base treated pollens when compared to as received untreated pollens. Epoxy and polyvinyl acetate (PVAc) matrices were used to demonstrate the effectiveness of pollen as a filler, as a function of pollen loading and surface treatments/chemical modifications. Scanning electron microscopy (SEM) was used to determine interfacial morphology, a high throughput mechanical characterization device (HTMECH) was used to determine mechanical properties, and differential scanning calorimetry (DSC) was used to determine glass transition behavior. In epoxy, pollen was an effective load bearing filler only after modifying its surface with acid-base hydrolysis. In PVAc, pollen was an effective load bearing filler only after an additional functionalization with a silane coupling agent. Finally, the species of pollen incorporated in PVAc matrices was varied in order determine the effect of the size of surface nano- and micro- structures on wetting, adhesion, and composite properties. Composites containing pollen displayed enhanced wetting and interfacial adhesion when compared to composites with smooth silica particles. Additionally, it was observed that pollen with smaller surface structures were wetted more effectively by the polymer matrix than pollen with larger structures. However, mechanical properties did not suggest significant changes in interfacial adherence with varied pollen microstructure size. The results of this work highlight the feasibility and potential of utilizing pollen as a natural filler for creating high strength, light-weight polymer composites with sustainable filler.

Background: Exposure of non-sustainable practices put MNCs in bad light, hurting their brand image. Therefore, it is of great importance to ensure supplier sustainability upwards the chain. Vast focus has been put on the first-tier suppliers. However, there are few studies that have investigated the issue of second-tier supplier sustainability, and there are many real life examples of firms’ who failed to ensure second-tier supplier sustainability. Hence, the need for further investigation within the subject.   Purpose: The purpose of this study was to investigate how two Scandinavian-based MNCs ensure second-tier supplier sustainability within their supply chain.   Methodology: This thesis is conducted with an inductive approach, collecting qualitative data through semi-structured interviews and archival research, at two independent companies. Thus, a multiple case study. Empirical findings were analyzed through a template analysis. Based on the theoretical framework and formulated research questions, categories have been derived, constructing the outline for our empirical findings and analysis.   Conclusions: (I) Social and cultural distance are major determinants settling which second-tier suppliers being regarded as critical. Conclusively, these two factors are the major determinants identifying whom to prioritize. Furthermore, IT is recognized as a vital and beneficial tool to utilize when mapping the network of second-tier suppliers. (II) In order to achieve second-tier supplier compliance of CoC, “the grey area approach” is identified as the used approach by investigated companies. Further, long-term relationships with first-tier suppliers are a major key in order to ensure second-tier sustainability in long-term perspective. (III) Last but not least, first-tier supplier network investigation is regarded prior to choosing a first-tier supplier. However, it is nothing decisive since other factors are more important in the process.

The pursuit of urban sustainability is considered central to sustainable development and is a key objective of the global Sustainable Development Goals (2015) and the New Urban Agenda (2016). This thesis aims to contribute to debates on urban sustainability by providing insights as to the role of actors participating in processes of governing for urban sustainability, with particular focus on the municipal organisation. The thesis employs an interdisciplinary approach to illustrate divergent approaches to governing for urban sustainability, with reference to empirical studies of strategic planning processes in municipalities in selected North-western European countries – Sweden, Switzerland and The Netherlands. These studies address themes including climate change, sustainable transport and multi-level governance. The thesis provides a broad overview of theoretical discussions related to governing, strategy and planning, the role of actors in governing for urban sustainability, and the particular importance of climate change as a challenge for urban sustainability. A number of research gaps are identified and addressed in two research questions, focusing on the organisation and practice of processes of governing for urban sustainability, and the factors influencing actors participating in such processes. The thesis responds to these research questions with reference to five appended papers, which illustrate different dimensions of governing for urban sustainability. The first paper concerns the organisation of processes to develop energy and climate strategies in Swedish municipalities, and the second paper highlights the experiences of actors participating in such processes. The third paper presents results from a survey illustrating the expectations of stakeholders active in governing transport in the city of Norrköping, Sweden. In the fourth paper, the development and implementation of policies aiming for sustainable transport and urban sustainability in Basel, Switzerland, are discussed. In the final paper, cooperation through transnational municipal networks is explored with reference to the World Ports Climate Declaration, an initiative of the city of Rotterdam. The thesis confirms the presence of five factors – capacity, mandate, resources, scope and will – that shape the “strategy space” of actors and play an important role in conditioning the form and content of processes of governing for urban sustainability. The thesis suggests that the ways in which a municipal organisation perceive and mobilise the five factors will strongly determine the extent of its sustainability strategy space. In sum, municipal organisations and other actors participating in processes of governing for urban sustainability need to mobilise the five factors and expand their strategy space, in order to achieve vertical and horizontal alignment of strategic objectives and facilitate implementation that delivers transformative change.

To readjust the direction of social development and to enable sustainable learning for students at all levels, international policy emphasises the necessity to transform education systems based on a whole institution approach. The idea of involving all stakeholders in the transformation of educational environments shifts the focus of research in connection to education for sustainable development (ESD) also towards the teachers and students as protagonists of didactic situations, in order to gain knowledge on their respective potential to contribute to the desired change of learning and teaching environments. Concentrating on sustainability-related study programs at leading universities in Germany and Sweden, this comparative case study investigates how different actors in the field conceive of the role of students as change agents in higher education for sustainable development (HESD). Recent research has largely ignored learners as potential initiators of change in this regard. Taking a discourse analytical approach and referring to the concept of different educational traditions in environmental education (EE), the focus of this thesis is on didactic contracts among teachers and students, to analyse how the general organisation of learning as well as the degree to which students apply critical thinking and transformative action in class is perceived by experts, teachers and students themselves. It is investigated if and how active and critical participation on part of the students is actually seen to contribute to changing their own learning environments. The didactical perspective on students as critical change agents, shaping their own learning processes, helps to understand to what extent HESD in these two countries – both considered ‘advanced’ in implementing ESD – allows students to gain the experience of achieving change in learning, fostering their confidence to initiate change outside of academia also. The findings of this research indicate that students are generally expected and seen to act as change agents within their own learning processes. However, it is to emphasise that the degree of change agency on part of the students appears not only to differ between the examined institutions and course formats, but also to be depending on individual personality traits of students and the establishment of a critical learning culture.

The global community faces ecological problems with the natural environment and cultural impediments to solving them. Natural systems are constantly changing and so are cultural practices. Humans need to address both: the interaction between those dynamic systems, the natural and cultural, because what happens in one system changes things in the other. The changes to the ecosystems are rapid and sometimes irreversible while dealing with them has been inadequate. Environmental movements, including deep ecology, have been at the forefront of the efforts to engage the public, various groups, politicians, and world governments to address environmental problems on a coordinated large scale, but their efforts have not produced substantive results. Cultural, ideological, and other reasons provide some insights into the reasons why this has happened. They show that the ecological crisis is now at the point at which deep ecological principles offer a way out of the crisis more clearly, given that it offers a new, ecological worldview for humans to adopt. This worldview suggests there is inherent unity between the human and natural worlds based on the concept of interdependence. This paper attempts to show that such inherent unity exists and that humans need to use precaution because the risks are too great to ignore.

Sustainable Built Environments Senior Capstone Project / This paper examines Subsurface Drip Irrigation(SDI) as a solution to water conservation in landscape irrigation. This is a problem because of the drought that the southwestern United States is experiencing, and the amount of water that landscapes utilize and which is ultimately wasted due to inefficient practices. Subsurface drip irrigation represents a potential solution due to its high efficiency and water saving ability; however, there are some problems within it as a system. Utilizing a multiple case studies approach, this paper looked at three of the top irrigation companies, Rain Bird, Toro, and Netafim, and examined how they innovated to overcome the problems with SDI. Synthesizing the best and most effective practices from each company, a model for improving SDI was generated.

Sustainable Built Environments Senior Capstone Project / In a society growing towards alternative modes of transportation, this study explores the phase 2 streetcar expansion for the Tucson area. Using case studies and research articles, a criteria of factors were created to best judge three predetermined expansion routes. A case study was then done on these routes to determine which route would be best for the area. In this study, the factors that were looked at and used to rank the three routes included; population density and average annual income of the surrounding area of the route (400 meter buffer), accessibility and connectivity, which includes; bus stops, bike lanes, walkability, traffic counts and possible park & ride development. The last factor used in the case study was proximity to destination, specifically how many ‘big destinations’ (destinations that experience high volumes of people) each route had. The proximity to destination factor also determined how good of a balance each route had with housing, work and amenities/leisure destinations.
