This thesis explores the application of Green Growth strategies in Rwanda, focusing on community resilience and systemic leadership within the Green Village Model. The research addresses the gap in understanding how these strategies are adopted in the challenging socio-economic contexts of the Global South, with a specific examination of Rwanda's pioneering Green Village. Using a qualitative case study approach, this study involved interviews with key stakeholders including government officials, community members from the Green Gicumbi village, and experts in the mentioned theoretical frameworks.  Findings indicate that Rwanda's adoption of Green Growth strategies is contextually driven, reflecting the unique socio-economic and environmental challenges faced by the communities. Systemic leadership has emerged as crucial in fostering an environment that enhances community resilience, thereby supporting the successful implementation of Green Growth. This interconnectedness significantly bolsters the community's capacity to adopt green technologies, manage resources sustainably, and enhance socio-economic well-being. The study contributes to the theory of sustainable development by providing insights into the dynamics of Green Growth strategies in the Global South. It underscores the importance of aligning such strategies with local needs and conditions to ensure their effectiveness and sustainability. The thesis also offers practical recommendations for policymakers and stakeholders involved in crafting andadopting Green Growth strategies, suggesting that fostering leadership that appreciates systems interdependencies and community-driven initiatives can significantly enhance the resilience and sustainability of vulnerable communities.

The Paris Agreement has stipulated global lowering of carbon emission to reach the 1.5°C target by 2030. The Intergovernmental Panel on Climate Change has suggested several scenarios with rapid innovation and downscaling of energy usage. Against this background, this thesis analyzes the productive capacity of Sweden to reach the corresponding carbon emission target. A product-byindustry input-output-model of the economy to study different re-allocations of production is used. The effect of these re-allocations on the output as well as carbon dioxide emissions from domestic production are considered. Linear optimization is used to achieve efficient re-allocations. Two scenarios are considered: one called the “basic case”, and one called the “efficient export case”. The basic case uniformly rescales the output. The efficient export case internalizes the export and allows it to be uniformly rescaled by the optimization up to trade balance as well. The data is from 2016 as it is the latest data with the necessary information. The result for the basic case shows that the 1.5°C target in 2016 can be reached without downscaling the output. The total employment shrinks by 2%, while some sectors of the economy are significantly changed. The result of the efficient export case has a similar result while total employment shrinks by 11%. The basic case releases 2% less than the reported carbon emissions, and the efficient export case 24% less where the efficient export case downscales the gross domestic product with 13%. The dynamics of innovation, negative impacts on production, and population growth are not accounted for in these estimates. Further studies need to internalize more constraints and develop more detailed models to provide more accurate policy guidance.

The Exploitation of land for economic growth has been an ongoing issue for locals’ rights to land, especially indigenous people. In Sweden, EU’s largest producer of Iron ore, the conflict between the State, indigenous Sámi, and mining industries have caused many controversies over the years, where mining projects repeatedly infringe upon land inhabited by Sámi. It is argued that exploitation is a “common good” for economic and social development, arguments which are rooted in the historical oppression and colonialist thoughts of the past. Recently, the argument has shifted, adding environmental concerns, where development projects claim to be an indispensable part of the national and global green transition. Ideas stemming from green growth narratives, such as technological solutions, are consistently put forward as the right path towards a green transition, with little consideration paid towards communities who pay the price. One such instance is the case of the proposed mine in Gállok, which was granted a processing concession in 2022. The project is asserted to be a necessity for producing green iron ore for a sustainable future, while opposing parties argue that it will cause irredeemable consequences on the environment and the Sámi village Jåhkågasska tjiellde. This Master thesis investigates these narratives through Critical Discourse Analysis and an Environmental Justice framework to elucidate misrecognition within green growth politics and how arguments contrived from ideologies and beliefs shape the mainstream narrative. It is not to impart an absolute truth but to highlight one potential contributing factor to the current situation. Documents provided by the Company, the State and Sametinget are used as a basis for the analysis, where they are analysed through themes based on perceived recognition, narratives, and power structures, Namely Language, Representation, and (De)politicisation. It is found that while some progress has been made concerning Sámi rights generally in Sweden, little of it can be observed within the discourse regarding the mine. Both company and the State still lean heavily on technical solutions to create coexistence between the mine and Sámi, something which the Sámi affirms is not a possibility. It is further concluded that a green transition which claims to be sustainable needs to consider the social repercussions against the indigenous experience, heritage, livelihood, and culture to be truly sustainable. / Exploatering av mark för ekonomisk vinning och urbefolkningars rättigheter är ett kontroversiellt ämne globalt. I Sverige, EU:s största producent av järnmalm, har konflikten mellan staten, samer och gruvindustrin orsakat många kontroverser genom åren, varav gruvprojekt kontinuerligt inkräktar på land som brukas av samer. Det hävdas att sådan exploatering genererar en "allmännytta" för ekonomisk och social utveckling, argument som har sina rötter i gamla koloniala världsbilder och historiska förtryck av samer. På senare tid har argumenten för exploatering även inkluderat miljöfrågor, varav utvecklingsprojekt hävdar att de är en väsentlig del av den nationella och globala gröna omställningen. Idéer som härrör från grön tillväxtteori, såsom tekniska lösningar, presenteras konsekvent som den rätta vägen mot en grön omställning, med lite hänsyn till dem som betalar priset. Ett sådant exempel är fallet med den föreslagna gruvan i Gállok, som beviljades en bearbetningskoncession 2022. Projektet hävdas vara en nödvändighet för att producera grön järnmalm för en hållbar framtid, medan motparter hävdar att det kommer att orsaka oåterkalleliga konsekvenser för miljön och samebyn Jåhkågasska tjiellde. Detta examensarbete syftar till att undersöka aktörers olika narrativ genom kritisk diskursanalys och ett ramverk för miljörättvisa för att belysa felerkännande av samiska rättigheter inom grön tillväxtpolitik, och hur argument formade av ideologier påverkar den breda diskussionen. Dokument som hämtats från Beowulf Mining PLC, Staten och Sametinget används som underlag för analysen, där de analyseras genom teman hämtade från upplevd igenkänning, narrativ och maktstrukturer, Nämligen Språk, Representation och (Av)politisering. Det visar sig att även om vissa framsteg har gjorts när det gäller samernas rättigheter generellt i Sverige, kan lite av detta ses i diskursen gällande gruvan. Både företaget och staten lutar sig fortfarande hårt mot tekniska lösningar för att skapa samexistens mellan gruvan och samerna, något som samerna hävdar inte är en möjlighet. Vidare dras slutsatsen att en grön omställning som gör anspråk på att vara hållbar måste ta hänsyn till de potentiella konsekvenserna för samiska erfarenheter, arv, försörjning och kultur för att verkligen kunna bedömas som hållbar.

Global raw material extraction has accelerated since the 1950s, causing resource depletion, ecosystem degra- dation, pollution, and climate change. To reduce such impacts, the economic drivers of material use must be addressed. Although economic growth often drives material use to increase, this increase can be counter- acted by dematerialization. This study explores whether dematerialization can achieve sustainable material footprints in Sweden by 2050, considering different scenarios of economic growth. Environmentally extended multi-regional input-output analysis was used to calculate the Swedish material footprint from 1995 to 2011. Structural decomposition analysis was used to quantify how much dematerialization, economic growth, con- sumption and trade patterns, and population drove the changes in the material footprint. Based on previous literature, 6 tons of materials per person was used as a sustainability target in three backcasting scenarios, reflecting degrowth, growth, and growth with ambitious shifts towards less material intensive consumption and trade patterns, respectively. The Swedish material footprint increased from 211 to 279 Mt from 1995 to 2011. While relative dematerialization did occur, economic growth caused material use to grow. If the economy degrows, the 2050 target can be reached with dematerialization rates of 0.7 times the previous rates. To reach the target under continued economic growth, dematerialization rates must increase by a factor of 1.8-2.7, depending on the extent of shifts to less material intensive consumption and trade patterns. Although further research is needed to examine whether such unprecedented rates of dematerialization are feasible, the results suggest that degrowth must be considered. / Råvaruutvinningen i världen har ökat kraftigt sedan 1950-talet, vilket leder till resursbrist, degraderade ekosystem, föroreningar och klimatförändringar. För att minska den miljöpåverkan behöver drivkrafterna bakom samhällets materialanvändning angripas. Ekonomisk tillväxt driver på råvaruutvinningen, men resurseffektivisering kan minska den. Den här studien undersöker hur resurseffektivisering,dematerialization på engelska, kan uppnå en hållbar materialanvändning i Sverige 2050, beroende på hur den ekonomiska tillväxten utvecklas. Data på nationella och internationella ekonomiska flöden och deras miljöeffekter, environmentally extended multi-regional input-output data på engelska, användes för att räkna ut Sveriges materialanvändning ur ett konsumtionsperspektiv från 1995 till 2011. Strukturell dekomponering användes för att kvantifiera hur mycket resurseffektivisering, ekonomisk tillväxt, konsumtions- och handelsmönster och befolkningsstorlek drev förändringarna i materialanvändningen. Baserat på den befintliga litteraturen användes 6 ton material per person som ett hållbarhetsmål i tre scenarier, som representerade nerväxt, tillväxt och tillväxt där konsumtionen samtidigt blir mindre materialintensiv. Den svenska materialanvändningen ökade från 211 till 279 Mt mellan 1995 och 2011. En viss resurseffektivisering skedde under perioden, men den ekonomiska tillväxten bidrog till att materialanvändningen ändå ökade. Om ekonomins storlek minskar kan hållbarhetsmålet nås 2050 med en resurseffektiviseringstakt som är 0,7 gånger takten från 1995 till 2011. För att nå målet med ekonomisk tillväxt behöver takten i resurseffektiviseringen öka med en faktor mellan 1,8 och 2,7, beroende på hur stora skiftena till mindre materialintensiva konsumtions- och handelsmönster är. Mer forsknings behövs för att undersöka huruvida en så snabb resurseffektiviseringstakt är realistisk, men resultaten visar att nerväxt kan vara ett alternativ.

This study investigates vertical farming and its potential as an efficient agricultural method. With significant potential, including higher yields per unit area to address critical issues suchas food shortages. The method boasts increased productivity within a limited space, presenting a substantial crop yield compared to traditional farming practices. This makes VFparticularly relevant in the face of a growing global population, particularly in urban areas,and provides a viable means of cultivating food in regions plagued by challenging climateconditions. Despite its numerous advantages, VF encounters potential challenges, notably interms of customer acceptance. Concerns among the general public may arise due to theunconventional setting of plant production, reliance on artificial light, and associated costs. Consequently, there is a crucial need to delve into and evaluate the acceptance of VF productsby consumers. This thesis aims to provide in-depth insights into the acceptance of VF amongconsumers in European countries. By addressing concerns and perceptions addressingsustainability, cost, and the unconventional nature of VF systems, the research seeks tocontribute valuable knowledge to the discourse on the future of agriculture and its role inmitigating food shortages. Through a nuanced exploration of customer attitudes andexpectations, this study aspires to shed light on the potential challenges and opportunities forthe widespread adoption of vertical farming in European contexts. However, the findings of this paper indicate that, at present, VF products are suitable for aspecific segment of young and affluent consumers. The primary factors influencing thechoice of these particular customers are a general lack of awareness and the high associated costs. The acceptance of VF products by European consumers may positively influence theirpurchasing choices due to factors such as sustainability, technological awareness, innovation,novelty, curiosity, quality, absence of chemicals, freshness, trust in government rules andregulations, and the direct purchase option. Conversely, it could have negative effectsattributable to a high price, lack of awareness, adherence to traditional values or distrust oftechnology, absence of organic labels, or a preference for alternative organic methods. The primary opportunities for customer attraction lie in affluent area supermarkets. Asmentioned earlier, a significant barrier observed among consumers is their lack of awarenessregarding VF products. It is recommended that VF organizations devise strategies tointroduce their products and services via the internet and diverse media, tailored to thegeographic locations of their consumers. Participants with pre-existing knowledge providedthe most positive feedback regarding the acceptance and purchase of VF products. Additionally, given the local proximity of VF to cities, facilitating direct purchases at thefarm could further enhance customer appeal. Positive mentions from participants include trustin the direct supply chain and a lower price. The primary hurdle involves the imperative to expand operations and decrease expenses torevolutionize the industry, making it accessible to a wider audience. Minor challenges includetechnological skepticism, absence of organic labeling, variability in electricity costs, and aprevailing lack of awareness regarding VF, although this may change over time. Prospectiveresearch could quantitatively explore variations among countries and demographic factorsinfluencing customer acceptance of VF products

Die drei Essays dieser Dissertation verbinden Themen der wirtschaftlichen Entwicklung und des Klimawandels. Alle Essays erörtern die allgemeine Frage wie steigende Einkommen und Austauschbeziehungen in Umweltfragen verbunden werden können und konzentrieren sich dabei auf CO2 Emissionen als Hauptverursacher von Treibhausgasen. Die Forschungsarbeit beleuchtet die wesentlichen Treiber und Verteilungswege von CO2 Emissionen und zeigt wie wirtschaftliches Wachstum, Energieverbrauch und Emissionen interagieren. Im ersten Essay wird am Beispiel Indonesiens der ökologische Fußabdruck von Haushalten durch ihre Konsumentscheidung aufgezeigt. Es werden Muster, Determinanten und die Aufschlüsselung der steigenden Emissionen der Haushalte analysiert. Die Arbeit konnte zeigen, dass die Sektoren mit Leichtöl und im Transportwesen die intensivsten Emittenten in Indonesien sind und ein signifikantes Ungleichgewicht der Karbon-Emissionen zwischen Haushalten besteht. Sie konnte zudem darlegen, dass ein steigendes Einkommen die wichtigste Determinante der Haushaltsemissionen sind. Die Aufschlüsselung des Emissionswachstums legt nahe, dass die steigenden Emissionen zwischen 2005 und 2009 hauptsächlich auf den steigenden Wohlstand der Haushalte zurückzuführen sind.  Eine gerechtere Haushaltsverteilung besitzt -wie jedes Emissionsreduzierungskonzept- einen größeren Effekt zur Abschwächung des Klimawandels in einer Gesellschaft mit weniger Ungleichheit als in einer Gesellschaft mit verstärkter Ungleichheit.  Im zweiten Essay wurde die Ungleichheit von Haushalts-Emissionen und die Aufschlüsselung der Emissionsungleichheiten in ihre Ursachen untersucht.. Die Studie zeigt einerseits eine steigende Ungleichheit unter den untersuchten Haushalten als auch dass Energie-Transport hauptsächlich für höhere Emissionsungleichheit verantwortlich ist. Der dritte Essay untersucht kausale Zusammenhänge zwischen Emissionen, Energieverbrauch und wirtschaftliche Entwicklung gemeinsam mit Urbanisierung und Investitionen im Falle von Indonesien unter Verwendung von Zeitreihenanalyse. Diese Studie zeigt eine Granger-Kausalität von Output und Energieverbrauch hin zu Emissionen, aber nicht in die entgegengesetzte Richtung von Emissionen zu Output. Dies weist darauf hin die Möglichkeit Emissionen zu reduzieren ohne Wachstum zu hemmen. Damit könnte Energieverbrauch die hauptsächlich verändernde Variable zwischen Output und Emissionen sein. Urbanisierung und Kapitalformation können CO2 neutral sein, wenn das betreffende Land nachhaltige städtische Entwicklung, grüne Investitionen und Energieeffizienz zur Entschärfung des Klimawandels fördert. Jeder dieser Essays trägt zu der Literatur dazu bei, wie ökonomische Aktivitäten (wie steigender Konsum) steigende Emissionen - eine der wichtigsten Externalitäten menschlicher Entwicklung - bedingen. Andersherum könnte Umweltzerstörung (und/oder entschärfende Maßnahmen) weitere Entwicklung menschlichen Wohlbefindens erschweren. Passende Politikmaßnahmen, der Konsum in Richtung von weniger emissionsintensiven Ausgaben stimulieren, könnten implementiert werden. Aber insbesondere in Entwicklungsländern, die mit Energieeffizienz (CO2 intensive Energiesysteme), ungenügend grünen Infrastrukturen, Städteplanung, öffentlichem Nahverkehr und hohen (und ungünstig gezielte) Treibstoffsubventionen zu kämpfen haben, könnte dies schwierig werden. Diese Themen könnten dann nicht nur für Indonesien als entwickelnde Ökonomie sondern auch bei globalen Debatten dazu beitragen, wie Entwicklungspfade weniger kohlenstoffintensiv gestaltet werden können und damit substantielle Bedeutung erlangen.

Since the concern about the negative impacts of the current economic modelin the scarcity of natural resources and their conservation, it comes the need toconfront them and create, from academia, some research areas that include thesenew features and development trends. In this paper, an overview of the conceptualaspects of the main proposals for the transition to sustainable development isperformed, such as the Green Growth, Bio-Commerce, Bio-Economy, amongothers.

Cette thèse fournit une illustration numérique de la façon dont une taxe carbone pourrait affecter le PIB, l’emploi, les émissions de CO2 et les inégalités socio-économiques en Afrique du Sud. Elle utilise un modèle d’équilibre général calculable « hybride » en économie ouverte par projection en un seul pas de temps de 2005 à 2035. Le modèle représente des économies de second rang, notamment des rigidités sur le marché du travail liées aux niveaux de qualification et dans la production électrique. Sept scénarios basés sur des modalités différentes de recyclage de la taxe carbone sont analysés, plus une option d’investir une partie des revenus de la taxe dans l’amélioration des qualifications de la force de travail.L’analyse montre que sous hypothèse standard de changement technique, une taxe carbone de 100 ZAR par tonne de CO2 environ a peu d’impact négatif sur le PIB et l’emploi lorsqu’elle est associée à un mode de recyclage des revenus approprié : subventionner le facteur travail et réduire les taxes sur les profits des entreprises pourrait conduire aux meilleurs résultats macroéconomiques, mais ne réduit pas les inégalités. Des mesures supplémentaires sont nécessaires pour réduire la « pauvreté énergétique ». Pour atteindre le NDC d’Afrique du Sud au titre de l’Accord de Paris, un taux de taxe d’environ 300 ZAR ou 55$ par tonne de CO2 serait nécessaire. Toutefois, un tel taux pourrait avoir un impact significatif sur la croissance du PIB. En même temps, sans changement de la tendance de croissance de la productivité du travail, ce PIB plus faible conduirait à un chômage plus élevé que dans le cas de référence. Une politique d’investissement de 7.5 milliards de ZAR de revenus carbone dans les qualifications de la main d’œuvre, avec l’objectif d’augmenter l’accès à la formation de haut niveau et de réduire le manque de salariés très qualifiés, pourrait avoir un effet très positif sur la croissance du PIB.Le progrès technologique, les préférences des consommateurs et le contexte international, limitent la capacité de l’économie à se restructurer et se décarboner et incidemment à réduire les impacts négatifs de la taxe carbone sur la croissance du PIB. Une véritable évaluation du changement technologique futur serait pertinente pour tous les secteurs et facteurs de production. Ces résultats impliquent aussi que la politique climatique internationale doit traiter la question des transferts de technologie et celles des potentiels différents de décarbonation sérieuse à l’échelle nationale. / This PhD thesis gives a numerical illustration of how a carbon tax affects South African GDP, employment, CO2 emissions and socio-economic inequality. It uses a “hybrid” computable general equilibrium model of an open economy in a one-step projection from 2005 to 2035. It models second-best economies, notably skill-related rigidities in the labour market and in production of electricity. Seven scenarios for recycling of carbon tax revenue are analysed, plus an option to invest a part of tax revenue in improvement of skills of labour.The analysis shows that under conventional assumptions about technological change, a carbon tax of around 100 ZAR2005 (18 USD2013) per tonne of CO2 will have little negative consequences for GDP and employment, when combined with the right type of tax revenue recycling: Labour subsidies and company profit tax reduction likely lead to the best macro-economic outcomes, though do not reduce inequality. Additional measures are needed to reduce “energy poverty”. To achieve South Africa’s NDC of the Paris Agreement, a carbon tax rate of around 300 ZAR2005 or 55 USD2013 per tonne of CO2 is necessary. However, this could have serious impacts on GDP growth. Also, without a change in the trend of increasing labour productivity, such lower GDP will lead to higher unemployment than in the reference case. An investment in skills of 7.5 billion ZAR2005 of annual Ctax revenue, with the objective of increasing access to high quality education and reducing the high skill labour shortage, if fond to have a very positive impact on GDP growth. However better calibration data is required.The findings of this PhD thesis furthermore call for thorough examination of what type of technological change could be expected for South Africa. Technological progress, consumer preferences and international circumstances limit the economy’s capacity to restructure and decarbonise and therefore to reduce negative consequences of carbon taxation for GDP growth. Proper assessment of future technological change is relevant for all sectors and inputs. Examples are given which show that energy and materials efficiency have an important role for future GDP growth under carbon constraints, because they determine the economy’s flexibility to reduce energy consumption and to substitute it, e.g. by labour. This finding normally holds not only for South Africa, but also for the rest of the world. These results also imply that international climate policy has to address technology transfer and the different potentials of national economies to decarbonise seriously.

The concepts of degrowth and green growth are central in the scientific discussion on resources, climate change and sustainability. This thesis investigates to what degree the concepts are present in the Swedish government’s climate policy. The two climate policy action plans that have hitherto been presented by the government was analysed through a quantitative text analysis method and the findings where then compared with each other. The analysis suggests, unsurprisingly, that green growth is the dominant perspective in both action plans although there exist clear differences in emphasis of the perspectives.  The current right-wing government stresses that economic growth should be considered a prerequisite for the transition to sustainable development whilst the former left-wing government tries to merge the concepts of degrowth and green growth although with an emphasis on the later.  The findings show that different perspectives on economic growth are present in Swedish climate policy and that the concepts of degrowth and green growth are useful tools to analyse and comprehend these perspectives. The findings raise questions whether opinions on economic growth, as expressed in the government’s action plans, are a result not only from party ideology but also from power struggles within respective government coalition.

Ce mémoire traite des représentations du vivant portées par l’imaginaire sociotechnique de la biologie de synthèse. Domaine technoscientifique en pleine expansion, elle a comme objectif de fabriquer des entités biologiques détenant une application commerciale. En plus de ses visées économiques, les promoteurs de la biologie de synthèse annoncent qu’elle constitue une solution aux enjeux engendrés par la crise écologique. Ce type de promesse étant moins étudié par la sociologie des sciences et des technologies, ce présent mémoire fera lumière sur cet enjeu. Je montrerai que la biologie de synthèse s’inscrit dans le modèle bioéconomique qui implique une mise en ressource à large échelle globale des processus biologiques. L’imaginaire de la biologie de synthèse reconduit ainsi une double promesse : poursuivre le modèle de développement industriel tout en évacuant les limites écologiques qui s’y posent. Avec une analyse des discours médiatiques et publicitaires relatifs aux promesses écologiques de la biologie de synthèse, je démontrerai que son imaginaire s’appuie sur une représentation machinique et informationnelle du vivant. Par le fait même, cette analyse montrera que la volonté de mettre les processus biologiques en ressource se décline elle-même en deux tendances. D’une part, le vivant est posé dans les termes d’une matière première inerte et malléable. D’autre part, il est représenté comme une entité active qui peut être mise au travail. L’imaginaire de la biologie de synthèse relève donc d’une radicalisation de la volonté d’englober les processus biologiques dans la production industrielle. Les promesses écologiques de ce domaine apparaissent subordonnées à cette visée. / This thesis focuses on the representations of the living carried by the sociotechnical imaginary of synthetic biology. Synthetic biology is a fast-growing technoscientific field whose main objective is to manufacture biological entities with commercial applications. In addition to its economic aims, promoters of synthetic biology claim that it represents a solution to the challenges posed by the ecological crisis facing contemporary societies. As this type of promise is less studied by the sociology of science and technology, this thesis will shed light on this issue. I will show that synthetic biology is part of the bioeconomy, which proposes the large-scale transformation of biological processes into valuable resources. The imaginary of synthetic biology thus makes a double promise : to continue the industrial development model while bypassing its ecological limits. Through an analysis of media and advertising discourse relating to the ecological promises of synthetic biology, I will demonstrate that its imaginary underpins a machine-like, informational representation of living matter. Furthermore, this analysis will show that the desire to turn biological processes into resources underlies two trends. On the one hand, living matter is posited in terms of an inert, malleable raw material. On the other, it is represented as an active entity that can be put to work. The sociotechnical imaginary of synthetic biology thus reflects a radicalization of the desire to incorporate biological processes into industrial production. The ecological promises of this field appear subordinate to this aim.
