An important aspect of sustainable development is the social impacts from the consumption of goods and services. A recently developed method for social life cycle assessment (S-LCA) assesses the potential positive and negative social impacts along a product’s life cycle, while avoiding shifting negative impacts from one part of the supply chain to another. This thesis evaluated the applicability of S-LCA in three case studies, as well as a way of introducing an ethical perspective on the distribution of social impacts among stakeholders. The case study of laptop computers identified workers and the local community as the stakeholders at greatest risk of negative social impacts, with China, Russia, Saudi Arabia, Thailand and Brazil being most prone to these impacts. A case study of vehicle fuels identified some fossil and some renewable fuels with high or very high risks of negative impacts, suggesting a need for strict procurement requirements on social performance for all types of vehicle fuels. A study of e-waste recycling in Pakistan revealed negative social impacts on workers and the community, while decreasing poverty by providing employment. By performing a social hotspot assessment using S-LCA methodology, much can be learned about the potential social impacts associated with a product’s life cycle, and potentially important aspects that would otherwise have been neglected can be identified. Some methodological issues of S-LCA requiring further attention are: Indicator relevance. Impact pathways between indicators and performance assessment on social issues must be examined and improved. Aggregation and weighting of impacts and indicators. With major uncertainties still present, results must be transparent, but also aggregated for the purposes of interpretation and communication. Assessment of the use phase. To be more complete, S-LCA methodology needs to be complemented with an assessment of the use phase. Introduction of context. Identifying the context of relevant stakeholders in different parts of the life cycle would allow identification of the greatest leverage in improvement of social conditions. / En viktig del av hållbar utveckling är att hantera social påverkan från konsumtionen av varor och tjänster. Social livscykelanalys (S - LCA) är en metod som syftar till att bedöma positiv och negativ social påverkan av produkter under hela deras livscykel och samtidigt undvika att bara flytta negativ påverkan från en del av livscykeln till en annan. Denna avhandling utvärderar S - LCA i tre fallstudier, samt undersöker hur fördelningen av den sociala påverkan på olika intressentgrupper kan bedömas ur ett etiskt perspektiv. I en fallstudie som utfördes på en laptop identifierades arbetstagare och lokalsamhället som de intressenter, som löper störst risk för negativ social påverkan. Länder som Kina, Ryssland, Saudiarabien, Thailand och Brasilien var de som var mest kopplade till denna påverkan. En fallstudie kring fordonsbränslen visade att av de bränslen som bedömts uppvisade både en del fossila och en del förnybara bränslen höga eller mycket höga risker för negativ social påverkan, vilket tyder på att strikta upphandlingskrav gällande social prestanda behövs för alla typer av drivmedel. En studie av återvinning av elektroniskt avfall i Pakistan uppvisade påtaglig negativ social påverkan på arbetstagarna och lokalsamhället, samtidigt som återvinningen gav sysselsättning som minskar fattigdomen. Genom att använda S-LCA vid bedömningen av en produkt finns det mycket att lära om potentiell social påverkan från produktens livscykel. Viktiga aspekter, som annars riskerar att missas, kan nu identifieras med S-LCA. Metoden är dock inte färdigutvecklad, och metodfrågor som behöver ytterligare uppmärksamhet är: Relevanta indikatorer. Kopplingen mellan indikatorerna och den påverkan man försöker mäta måste undersökas närmare och förbättras. Sätt att aggregera och väga ihop påverkan. Med tanke på de osäkerheter som ännu så länge finns kring metoden måste resultaten hållas transparenta, samtidigt som sammanfattande resultat behövs för tolkning och kommunikation. Påverkan i användningsfasen. För att bli mer komplett, måste metoden kompletteras med en bedömning av social påverkan i användningsfasen. Sätta resultaten i sitt sammanhang. Utgångsläget för dem, som berörs av en produkts sociala påverkan avgör vilken hävstångseffekt en förbättring av de sociala förhållandena kan ha, och kan därmed påverka vilka åtgärder som bör prioriteras. / <p>QC 20131217</p>

A set of indicators has been developed by the author of this work to assess the social performance of Vattenfall’s products (electricity &amp; heat). This set of indicators has been adapted to the requirements of the International EPD® system. The aim has been to create a set of indicators that can be applied to all processes within the lifecycle. The indicators are supposed to make a best possible statement of the social performance of a companies’ product, including the most relevant issues and topics within the pillar of social science and social sustainability. The method used for the development of the indicators is the Delphi method. The Delphi process includes several rounds of reviewing. A group of experts usually carries out the reviewing. In this study five rounds of reviewing has been conducted with the help of nine experts. The first round has been an extensive literature review. The 390 indicators found in the literature have been classified according to the system and the instruction of S-LCA, which are described in the Guidelines for Social Life Cycle Assessment of Products. The fifth round of reviewing has been the last one and consensus on the list of indicators could be reached. The outcome of the development process has been a set of 30 indicators. Not all subcategories proposed in UNEP/SETAC’s Guidelines for Social Life Cycle Assessment of Products have been covered. The indicators have been distinguished into two categories: core and additional. Some important social issues could not be expressed in the form of an indicator. They have been added in the final outcome of the paper, the ‘socioprofile’, as additional information. The measurement and impact assessment of qualitative indicators have been a major challenge of this study. Data availability can be seen as another critical field of the study and the application of the indicators. Other studies that have been conducted focused on a lower amount of indicators. The study has shown the possibility to quantify and measure social impacts to a certain degree. The proposed indicators are aiming at a globally focused assessment of social sustainability. The inclusion of experts and the group discussions with those experts have shown the importance of these indicators. The next step in the development of social sustainability indicators is the implementation of these indicators in a practical application and the study of the outcome. To be applicable within the International EPD® system, the Product Category Rules also have to be updated to allow for a Sustainable Product Declaration.

The effort on mitigating climate change has conjured up a vision of a bioeconomy. Therefore, industrial production has to turn away from fossil-based resources to bio-based ones. In Germany, the BioEconomy Cluster aims to establish a bioeconomy region that is based on non-food biomass, especially wood. The complexity of this transition raises doubts as to whether it necessarily leads to a better, more sustainable living in the regions. Currently, life cycle assessment tools are viewed as adequate to evaluate sustainability aspects associated to products. A method to analyse potential social effects of products is at an early stage. Therefore, this PhD thesis develops a social life cycle assessment approach to assess wood-based production systems in a bioeconomy region in Germany. A framework was formulated with major concepts and definitions applied. The goal and scope comprise to identify of social hotspots and opportunities of the foreground activities involved in a production system in a German bioeconomy region. The system boundary was defined as an area smaller than a country and major stakeholder categories were selected. In addition the organisations’ conduct was determined as the main unit of analysis. Based on the frameworks’ major elements a social indicator set with seven social indices (e.g. health & safety; participation) and 32 social indicators (e.g. accidents) was selected to make the inventories. Therefore, sustainability standards and sLCA case studies were screened and stakeholder interviews were conducted to set up a final set. Within this PhD thesis context-specific performance reference points (PRPs) were determined for the sLCIA phase. Compared with the organisations’ indicator values, they indicate a “relatively poor” or “relatively better” social performance (i.e. a social opportunity or hotspot). The PRPs considered the classification of economic sector of the assessed organisation and in some cases the size of the organisation as factors influencing the potential social effects. The framework provides major elements (i.e. a context-specific indicator set and characterisation approach) to assess relevant social effects associated with the organisations production activities involved in a products production. Therefore, the sLCA approach supports producer’s decision making which may mitigate negative social effects and accelerate positive ones.:Summary i Acknowledgements ii List of Publications vii List of Figures ix List of Tables xii List of Abbreviations xiii 1 Introduction 1 1.1 Bioeconomy and sustainability 1 1.2 The BioEconomy Cluster 2 2 Social Life Cycle Assessment, S-LCA 3 2.1 The history of sLCA 3 2.2 The UNEP-SETAC guidelines 4 2.3 Review on sLCA 5 2.3.1 Goal and scope definition 8 2.3.2 Social life cycle inventory 9 2.3.3 Characterisation 10 3 Research question and aim of the thesis 12 4 Social life cycle assessment: in pursuit of a framework for assessing wood-based products from bioeconomy regions in Germany 14 4.1 Abstract 14 4.2 Introduction 15 4.2.1 Germany’s wood-based bioeconomy 15 4.2.2 Social life cycle assessment 16 4.2.3 Goal and structure of the paper 17 4.3 Defining the goal and scope 17 4.3.1 Defining the goal—the purpose of the developed sLCA approach 17 4.3.2 Regional system boundaries 18 4.3.3 The production system 19 4.3.4 Stakeholder categories 19 4.3.5 Defining and using a functional unit 20 4.3.6 Activity variables—relating social effects to the product 21 4.3.7 Social indices and indicators 22 4.3.8 Developing context-specific social indices and indicators 23 4.3.9 Presenting the social effects to regional producers 24 4.4 Social life cycle inventory (sLCI) 25 4.4.1 SLCIs in global hotspot assessment studies 25 4.4.2 SLCIs in regional hotspot assessment studies 26 4.5 Social life cycle impact assessment (sLCIA) 27 4.5.1 Characterisation method: international PRPs 28 4.5.2 Characterisation method: national PRPs 28 4.5.3 Characterisation method: sector PRPs 29 4.5.4 Characterisation method: regional PRPs 29 4.6 An sLCA framework for regional bioeconomy chains 31 4.7 Summary and outlook 33 5 Social life cycle assessment indices and indicators to monitor the social implications of wood-based products 35 5.1 Abstract 35 5.2 Introduction 36 5.3 Materials and methods 38 5.3.1 Screening criteria 38 5.3.2 Overview of research steps 40 5.3.3 Screening of global sustainability standards 41 5.3.5 Screening of national sustainability and forest certification standards 43 5.3.6 Screening of sLCA case studies 43 5.3.8 Stakeholder interviews 44 5.3.9 Selection based on feasibility of implementation 46 5.4 Results and discussion 48 5.4.1 Index: health and safety 52 5.4.2 Index: adequate remuneration 52 5.4.3 Index: adequate working time 53 5.4.4 Index: employment 53 5.4.5 Index: knowledge capital 54 5.4.6 Index: equal opportunities 55 5.4.7 Index: participation 56 5.5 Outlook 56 5.6 Conclusion 57 6 How not to compare apples and oranges: Generate context-specific performance reference points for a social life cycle assessment model 59 6.1 Abstract 59 6.2 Introduction 60 6.2.1 Background 60 6.2.2 The RESPONSA framework 61 6.2.3 Goal of this work 64 6.3 Influence factors recognised in the context-specific characterisation approach for the German wood-based bioeconomy 65 6.3.1 Classification of the influential conditions 65 6.3.2 The geographical location 68 6.3.3 The economic sector 68 6.3.4 The size of the organisation 69 6.4 The scoring approach and data sources 69 6.4.1 The scoring approach 69 6.4.2 Data sources to determine PRPs 70 6.5 Characterisation approach for quantitative indicators 70 6.5.1 Characterisation of quantitative indicators (full data) 70 6.5.2 Characterisation of quantitative indicators (partial data) 71 6.6 Characterisation approach for qualitative indicators 73 6.6.1 Characterisation of qualitative indicators with binary answers on a sectoral level 73 6.6.2 Characterisation of qualitative indicators with ranked answers on a sectoral level 74 6.6.3 Characterisation of qualitative indicators on a sectoral and organisational size level 76 6.7 Exemplary case study 77 6.7.1 Classifying organisations in the product system 77 6.7.2 Determining the sLCIs 78 6.7.3 sLCIA step 78 6.7.4 Relating social effects to the product 81 6.7.5 Discussion of the results 83 6.8 Discussion and outlook 84 6.9 Conclusion 85 7 Discussion of the main results 87 7.1 Organisations as unit of analysis 87 7.2 A country as major system boundary 88 7.3 A context-specific indicator set 89 7.4 Impact assessment: Economic sector and organisational size PRPs 90 7.5 The interpretation of the results 92 7.6 Limitations of the approach 94 7.7 Use for the Cluster 95 7.8 Outlook 96 8 Conclusion 97 9 Use of RESPONSA – A REgional SPecific cONtext-ualised Social life cycle Assessment tool 100 9.1 The RESPONSA user interface 100 9.1.1 Inputs from the organisations 101 9.1.2 The calculation made by RESPONSA 102 9.1.3 Output for the organisation 103 References cv Appendix A cxiii Appendix B cxx Appendix C cxxiv CURRICULUM VITAE cxxviii Author contribution cxxx Eigenständigkeitserklärung cxxxiii Bibliographische Beschreibung cxxxiv

The aim of this thesis was to study governance aspects of informal electronic waste recycling and to provide better knowledge of the business in terms of structure, stakeholders, governance aspects and social impacts. The thesis consists of a cover essay and two papers appended at the end of the thesis. The cover essay summarizes the papers and puts them in context. The objective of Paper I is to study the business of informal electronic waste recycling in Pakistan and highlight its governance issues. Paper II assesses the social impacts of this business using UNEP-SETAC Guidelines. The thesis examines these specific questions: Q1) What is the current situation of informal e-waste recycling in Pakistan? Q2) Who are the important stakeholders and what are their roles in this business? Q3) What are the governance issues enabling this informal business? Q4) What are the social impacts for individuals and society arising from this business? Paper I presents the international and local e-waste flows, business structure, the stakeholders involved and the existing governance issues of the business. It shows weak enforcement of legislation, the complexities emerging with numerous stakeholders, the profitability of informal recycling, little concern for the health damaging exposure for workers from poorest and most vulnerable people in society, and the lack of awareness of the hazards involved results in several governance issues. The paper also highlights how this business lacks characteristics of good governance, which makes it a challenge to control this business. Paper II assesses the social impacts of informal e-waste recycling in Pakistan using UNEP/SETAC guidelines for conducting a Social Lifecycle Analysis (SLCA). It showed that this business has positive impacts relating to societal issues and individual/family economics, and in the economic development of Pakistan but otherwise most impacts were negative. The findings of Paper II fill an important data gap and can be integrated with data on other stages of ICT product lifecycle to produce a full SLCA of such products. / Syftet med denna avhandling var att studera styrningsaspekter informella återvinning elektroniskt avfall och för att ge bättre kunskap om verksamheten i fråga om struktur, intressenter, styrningsaspekter och sociala konsekvenser. Avhandlingen består av en täck uppsats och två tidningar bifogade i slutet av uppsatsen. Locket uppsats samman tidningarna och sätter dem i sitt sammanhang. Syftet med papper I är att studera verksamheten i informella återvinning elektroniskt avfall i Pakistan och belysa dess styrningsfrågor. Papper II bedömer de sociala konsekvenserna av denna verksamhet med hjälp av UNEP-SETAC riktlinjer. Avhandlingen undersöker dessa specifika frågor: Q1) Vad är den nuvarande situationen för informella återvinnings e-avfall i Pakistan? Q2) Vilka är de viktigaste intressenterna och vilka är deras roller i den här branschen? Q3) Vilka styrningsfrågor som möjliggör denna informella företag? Q4) Vilka är de sociala konsekvenserna för enskilda och samhället som följer av detta företag? Papper I presenterar internationella och lokala e-avfallsflöden, företagsstruktur, de inblandade aktörerna och de befintliga styrningsfrågor i verksamheten. Det visar en svag tillämpning av lagstiftningen, komplexiteten växande med många intressenter, lönsamheten för informella återvinning, lite oro för hälsan skadliga exponering för arbetstagare från de fattigaste och mest utsatta människorna i samhället, och bristen på medvetenhet om de risker inblandade resultaten i flera styrningsfrågor. Papperet belyser också hur denna verksamhet saknar egenskaper för god förvaltning, vilket gör det till en utmaning att styra denna verksamhet. Papper II bedömer de sociala konsekvenserna av informella återvinnings e-avfall i Pakistan använder UNEP / SETAC riktlinjer för att genomföra en social livscykelanalys (SLCA). Det visade sig att denna verksamhet har positiva effekter avseende samhällsfrågor och individ / familj ekonomi, och i den ekonomiska utvecklingen i Pakistan men annars de flesta effekterna var negativa. Resultaten av pappers II fyller ett viktigt tomrum uppgifter och kan integreras med uppgifter om andra stadier av IKT produktlivscykeln för att producera en full SLCA av sådana produkter. / <p>QC 20150525</p>

Yes / There is general agreement on the importance of green roofs as ways of reducing GHG emissions, reducing overall costs and improving sustainability in urban areas. This systematic literature review highlights life cycle sustainability assessment as an essential criterion to evaluate green roofs. A bibliometric analysis was used to quantitatively review relevant literature. The Scopus database was chosen as a bibliographic database of academic publications. Thes period of search started from 2003 and final search was conducted on February 15, 2023. Based on further in-depth reading, 88 publication records which met the selection criteria, including 74 papers and 14 conference papers. Researchers from the United States contributed almost 31 % of the documents. We evaluated leading studies in this field and discussed assessment method, system boundaries and research gaps through a critical literature review and a systematic search review. Finally, we propose a framework and identify a gap and future research. The environmental aspect of green roofs have received more attention than economic issues. We found that most economic evaluations of green roofs are limited to their construction stage. As yet there is no comprehensive social study on green roofs. We considered a unified study of the economic, environmental impact and social evaluation of green roofs to be warranted. Additionally, various measurement methods should be used to assess the economic profitability of green roofs over the long term. In summary, this study provides a deeper understanding of the environmental, social, and economic performance of green roofs and identifies research gaps as well as future research directions. / The full-text of this article will be released for public view at the end of the publisher embargo on 25 Nov 2024.

The purpose of the present degree project was to investigate the possibilities of assessing social sustainability and, on this basis, to carry out an equality analysis of wood as a construction material. The latter part of the purpose was met by carrying out social life cycle assessments focusing on gender equality: one for wood as anengineering material and one for house with wooden frame. The result was presented as a gender index which indicated the proportion of the work carried out by women. To gain more knowledge about wood as an engineering material a complete social life cycle assessment is necessary. A complete social life cycle analysis should not be reduced to a single measurement number by merging different effect categories of social sustainability. The conclusion in the report was that such an analysis is better to present in so-called polar diagrams where each individual impact category can be distinguished, but not necessarily all indicators. The method used to assess gender equality can be used to assess other impact categories.

Wuhan China and Borlänge Sweden collaborate to promote sustainable business growths. This thesis, being part of sustainable business project, aims to understand how business can contribute to sustainable development and explore mechanisms of social life cycle assessment. In an effort to answer research questions and further to achieve the general purpose, a BOD online monitor case study is described and analyzed by applying both qualitative and quantitative approaches. Data collection is based on interviews and documents. In the case of BOD online monitor, the thesis identifies Boffin and Universtar companies’ CSR levels. It also observes that SLCA method is able to discover Boffin and Universtar’s social performances at life cycle impact assessment stage and disclose online monitor’s social impacts at interpretation stage. The thesis finally concludes that business’ CSR level can be evaluated from three dimensions: companies’ goals on conducting business, business operation performances and resolved problems. SLCA method is able to disclose enterprises’ social performances, discover underlying factors that might hinder corporations’ ability to contribute to sustainable development and improve product’s social at the same time.

The purpose of this study is to create an understanding of what potential social impacts (both positive and negative) the concept of P&amp;F will have and could have if an implementation of the process would be done. Interviews are mainly used for providing input to the method S-LCA (Social Life Cycle Assessment) and by that fulfil the purpose. Two questions will be addressed: What are the potential social impacts of the P&amp;F concept on the stakeholders: worker, value chain actors, local community, and society, if integrated into an already existing pulp mill? What are the differences in terms of social impacts between the first and second generation of biofuels? Two methods are used to fulfil the purpose and to answer the related questions. First method is S-LCA as mentioned above. Second method is thematic analysis, where data from interviews is transformed into codes, then quantified and lastly divided into themes. The two mentioned methods work in parallel with each other. The result from thematic analysis shows that subcategories with high social impacts are, technology development, health and safety and contribution to economic development, mainly due to new equipment, job creations and technology. The results from the reference scales show an overall positive score, which means a positive social effect on a potential implementation of the P&amp;F. It was noted that the sustainable future of the concept is strongly connected with positive social impacts like technological development and costs for investments in new equipment on an industrial scale. Several factors are important to consider when assessing an implementation of a process like P&amp;F, and further focus should be put on assessing the negative subcategory health and safety related to a potential new fuel. For this to be possible, there is a necessity to further develop the S-LCA methodology. As the S-LCA to a larger part measures the potential negative impacts, one challenge will be to develop the methodology for the assessment of potential positive social impacts. The S-LCA is an ongoing developing process, where contributions from applying, demonstrating, and sharing findings play a significant role for future research. / Syftet med denna studie är att skapa en förståelse för vilka potentiella sociala effekter (både positiva och negativa) begreppet P&amp;F kommer att ha och skulle kunna ha om en implementering av processen skulle göras. Intervjuer används främst för att ge input till metoden S-LCA (Social Life Cycle Assessment) och därmed uppfylla syftet. Två frågor kommer att behandlas: Vilka är de potentiella sociala effekterna av P&amp;F-konceptet på intressenterna: arbetstagare, aktörer i värdekedjan, lokalsamhället och samhället, om de integreras i en redan befintlig massafabrik? Vilka är skillnaderna när det gäller sociala effekter mellan första och andra generationens biodrivmedel? Två metoder används för att uppfylla syftet och för att besvara de relaterade frågorna. Första metoden är S-LCA som nämnts ovan. Den andra metoden är tematisk analys, där data från intervjuer omvandlas till koder, sedan kvantifieras och slutligen delas in i teman. De två nämnda metoderna fungerar parallellt med varandra. Resultatet från den tematiska analysen visar att underkategorier med stor social påverkan är, teknikutveckling, hälsa och säkerhet och bidrag till ekonomisk utveckling, främst på grund av ny utrustning, jobbskapande och teknik. Resultaten från referensskalorna visar en övergripande positiv poäng, vilket innebär en positiv social effekt på en potentiell implementering av P&amp;F. Det noterades att konceptets hållbara framtid är starkt kopplad till positiva sociala effekter som teknisk utveckling och kostnader för investeringar i ny utrustning i industriell skala. Flera faktorer är viktiga att ta hänsyn till när man bedömer ett genomförande av en process som P&amp;F, och ytterligare fokus bör läggas på att bedöma den negativa underkategorin hälsa och säkerhet i samband med ett potentiellt nytt bränsle. För att detta ska vara möjligt är det nödvändigt att vidareutveckla S-LCA-metoden. Eftersom S-LCA till en större del mäter de potentiella negativa effekterna blir en utmaning att utveckla metoden för bedömning av potentiella positiva sociala effekter. S-LCA är en pågående utvecklingsprocess, där bidrag från att tillämpa, demonstrera och dela resultat spelar en viktig roll för framtida forskning.

Investigations of the textile industry and apparel sector often reveal unethical behaviours towards workers and lack of transparency in the value chain.  As consumers are getting more conscious and the external pressure and demand for more sustainable clothing increases, companies need to implement management systems to control their operations and ensure actions are socially responsible. The Social Life Cycle Assessment (S-LCA) methodology published by the United Nations Environment Programme in 2009 are suggested to measure positive and negative social impacts on stakeholders along a products entire life cycle, from cradle to grave. The methodology is still under development and no methods have yet been standardized or internationally recognized.   To contribute to the development of the S-LCA and its practical use in real world situations, the present study aims to evaluate the applicability of existing methodologies and tools by applying them to a cotton shirt from a small company in Sweden. The case study was performed by conducting an S-LCA following the four phases: Goal and scope; Life Cycle Inventory; Life Cycle Impact Assessment and; Life Cycle Interpretation. Generic country-level data and organisation specific data were collected through questionnaires, document review and desktop screening, while two different assessment tools were tested for the different data types. For generic country-level data, a Social Hotspot Assessment framework developed for this study, was applied and evaluated. For organisation specific data the existing Subcategory Assessment Method (SAM) was subject for feasibility evaluation.   The S-LCA conduction involved several application issues that affect the perceived applicability and feasibility of the methods. Problems identified relate to the definition of system boundaries and uncertainties in the choice of appropriate and relevant indicators. The major problems refer to data collection both in terms of availability and quality issues both with regards to the inventory and assessment phase. Further, in the assessment and interpretation phase uncertainties regarding assessment criteria’s and aggregation of results evolved when using the framework for identifying hotspots, affecting the reliability of the results.   Despite the identified issues, it is evident that it is possible to conduct and finalise a Social Hotspot Assessment using the methodology. However, based on the reliability issues of the results and the effort it requires, it is concluded that the applied framework is not feasible for smaller clothing companies with limited resources. The assessment of organisation specific data by applying SAM, is considered incomplete and identified issues reflect the incompatibility of the method and are thus not considered applicable or feasible for smaller companies.

L’utilisation croissante du vocable de la transition dans le débat public contribue à l’émergence de nouvelles méthodes de recherche dont les géographes commencent à se saisir. La transition invite à réfléchir dans un cadre d’action nouveau. Appliquée au domaine des énergies, elle rencontre le géographe dans ses interprétations des dynamiques spatiales. Ce cadre spatio-temporel inédit, où sont introduites les notions de territorialisation de l’énergie et de réversibilité, constitue une opportunité pour le géographe de penser ces enjeux nouveaux selon des approches du couple espace-temps réinterprétées. Dans ce contexte, la thèse vise à comprendre et à analyser les mécanismes socio-spatiaux mis à l’épreuve par le développement des énergies renouvelables, et plus particulièrement des éoliennes. La spécificité de la démarche réside dans une traduction géographique de l’Analyse de Cycle de Vie. Pour ce faire, la thèse réinvestit le concept de paysage dans son interprétation dynamique. Cependant, l’analyse de cycle de vie nous invite à repenser la dynamique paysagère selon la notion d’événement. La thèse interroge l’arrivée d’un projet éolien comme un événement et s’intéresse à ses modes de surgissement, les déstabilisations socio-spatiales induites et les mécanismes de régulation entrepris par les individus. L’objectif de la recherche est d’expérimenter la conduite d’une Analyse sociale de Cycle de Vie des représentations paysagères de l’éolien. L’ambition se voit confrontée à une contrainte majeure, celle du temps. Le temps imparti de la thèse rencontre les temps politiques et les temps de l’expérience. Événements construits ou événement subis, ils impactent différemment les représentations socio-spatiales selon des échelles de temps variables. L’intention d’une recherche diachronique nous enjoint à réfléchir aux enjeux épistémologiques et méthodologiques stimulants de l’élaboration d‘un corpus particulier où peuvent être analysées conjointement des données de natures et de sources diverses. L’analyse est menée sur les discours et particulièrement sur les références spatiales et les sensibilités des individus face à l’arrivée d’éoliennes sur un territoire. La thèse retrace les étapes des cycles de vie de l’événement-éolien traduites et interprétées selon les contextes de terrains. / The increasing use of the transition terms in the public debate contributes to the emergence of new research methods whom geographers begin to apprehend. Transition invites to consider a new action framework. In the matter of energy domain, the transition concept involves geographers in their socio-spatial interpretations. This new spatiotemporal frame, where are introduced the notions of territorialisation of the energy and the reversibility, provides an opportunity to consider these issues from a reinterpretation of the space-time couple. In this context, the thesis aims in understanding and analyzing of socio-spatial mechanisms tested by the renewable energies development, especially wind turbines. The specificity of this approach may be a geographical rendition of the Life Cycle Assessment method. For this purpose, the thesis requires the concept of landscape in its dynamic meaning. However, the life cycle assessment invites us to reshape the idea of landscape dynamics according to the notion of event. The thesis explores the arrival of a wind turbines project as an event and it focus on its sudden emergence, the induced socio-spatial destabilizations and the individual and social adaptations. The purpose of this research is to investigate a Social Life Cycle Assessment of the landscape representations of the wind energy. This ambition faces a time constraint. The allowed time of a PhD thesis faces political times and the times of the experience. Created events or suffered events impact the socio-spatial representations differently and over various timescales. Considering a diachronic study brings about rethinking the epistemological and methodological issues raised by a corpus which gathers several types of data, from different sources and which would be analyzed together. The analysis is led on discourses and especially on spatial textual references along with the individual sensibilities revealed when a wind turbines project is initiated on territory. The thesis tracks the life cycle steps of windpower-events that we interpret according to the socio-spatial context of the study terrains.
