With the development of information and communication technology (ICT), car sharing becomes more and more popular. It is a short-term car rental service and Volvo entered this market in 2019. The purpose of this thesis is to design for a seamless and personalized experience for car sharing users with the smartphone. A literature overview and user interviews were performed to get a general understanding of the user groups, usage patterns of the car sharing service and their experience of connecting the smartphones to the car. Two user tests were made to iterate the design and get to know users’ opinions about the design concepts. Personas and scenarios were built up and that made the basis for the design of user interfaces on the car-sharing apps and the \ac{IVI}. As a result, a concept solution was brought up. The general process of the car sharing service was: booking a car, finding a car, getting onboard, picking up friends, and getting offboard. For drivers, they can find and unlock the car seamlessly with the phone, get onboard with all preferred settings applied, safely log into the IVI system, easily pick up friends by seeing their position, and clear personal data when they return the car. For passengers, they can see the position of the car and estimated arrival time, scan a QR code to turn their phones to a remoter of the IVI system, directly send a destination to the IVI system, and share their favorite music. Nearly all the users liked the designed functions in the tests but the adoption of the service was mainly affected by two factors. One was privacy concerns and the other was function value. Users made a choice of how important more functions were compared with sequences regarding loss of privacy. More future research needs to be done to further validate the findings of this thesis and achieve the designed experience.

This master's thesis deals with the potential for a car-sharing service in Prague. The service allows renting cars for a specified number of hours. Car-sharing is a commonly offered service in cities of the developed world. The theoretical section of the thesis introduces car-sharing and the current level of its adoption. Next, two conceptual bases for the development of the business plan are presented. The first is the macroeconomic theory of natural capitalism. At the theory's core is the recognition of the importance of natural capital. An improvement in protection of natural capital can be achieved by raising the consumption of services, instead of material products. In the case of car-sharing, the consumer only pays for the actual use of car, not for the ownership. The second concept is social entrepreneurship, which is an inspiring alternative to managing a business entity. Its goal is not only financial gain, but also positive social impact. The impact in case of car-sharing is in lowering the number of vehicles on the road and improvement of quality of life in cities. The business plan includes two financial alternatives. The thesis concludes that running a car-sharing organization in Prague is conceivable, but requires support from the municipality. Car-sharing cannot be expected to generate quick profit, but rather the profit model builds slowly. The final part of the thesis presents balanced scorecard developed for the first year of operation with the goal of achieving the optimistic alternative modeled in the business plan. The key to success in the first year is gaining and retaining customers.

Cette dissertation a pour but de comprendre l’appropriation par les consommateurs d’objets ou lieux qu’ils partagent. En nous basant sur les théories de l’appropriation, de la consommation par l’accès et du design, nous questionnons la définition, l’émergence et la valeur perçue de l’appropriation en accès. Nous explorons les contextes de l’autopartage et du coworking au travers de quatre articles. Nos résultats mettent l’emphase sur le rôle des objets matériels dans la mise en pratique de l’appropriation par les consommateurs. Nous définissons l’appropriation du consommateur dans le cadre de l’accès comme la création de significations (valeur de signe, valeur de lien, bien-être dans l’usage) grâce à un ensemble routiniers de pratiques entre les consommateurs et les éléments matériels de l’activité de consommation par l’accès. / This dissertation aims to understand consumer appropriation of objects and places shared with others. We draw from theories of appropriation, access-based consumption and design to question the definition, the value and the emergence of consumer appropriation in access. We explore the contexts of car sharing and coworking spaces through four research articles. Our findings highlight the role of material objects in the enactment of consumer appropriation practices. We define consumer appropriation as the creation of meanings (sign value, linking value, wellbeing in use) enacted through a routinized set of practices between the consumer and the material elements of the access-based activity.

Projekt BeMobility: Carsharing mit e-Fahrzeugen Ziel war die Einbindung von Elektroautos in eine Carsharing- Flotte und ihre Integration in multimodale Angebotskonzepte. Nutzergerechte Mobilitätsangebote für urbane Räume wurden entwickelt und im Realbetrieb beurteilt; hierbei wurde die Attraktivität des Carsharing mit e-Autos untersucht. (Kapitel 1) Forschungsansatz: Feldtest mit multimethodaler Begleitforschung Die angewandte Forschung des InnoZ setzte auf eine Kombination verschiedener Methoden. Sowohl vor als auch während des Feldtests wurden potenzielle Nutzer bzw. Testkunden befragt. Dazu wurden die Methoden Lead-User-Integration, Fokusgruppen sowie breite Befragungen gewählt. (Kapitel 2) Interessenten und Testkunden: Männlich, gebildet und ÖV-affin Potenzielle Nutzer und Testkunden sind den sozialen Leitmilieus zuzuordnen. Sie können als sogenannte Lead User gelten. Die Begleitforschung mit über 500 Befragten in vier Teilstudien lässt wichtige Schlüsse auf Akzeptanz und zukünftige Verbreitung von e-Autos im Carsharing zu. (Kapitel 3) Elektrofahrzeuge: Hoher Fahrspaß, aber Reichweite kritisch Die Erwartungen potenzieller Nutzer aus der Vorfeldphase werden im Praxistest teilweise übertroffen. Dies gilt insbesondere für die Fahreigenschaften der Elektrofahrzeuge. Allerdings werden die Erwartungen an Batterie und Laden sowie speziell an die Reichweite nicht erfüllt. (Kapitel 4) Preisbeurteilung: Geringe Aufpreisbereitschaft für e-Carsharing Für elektrisch betriebene Fahrzeuge gibt es auch im Carsharing- Einsatz kaum eine Aufpreisbereitschaft. Für ausgewählte zusätzliche Services besteht auf Nutzerseite aber eine – wenn auch geringe – ergänzende Zahlungsbereitschaft. (Kapitel 5) Mobilitätskarte: Multimodales Angebot gut bewertet Die befragten Nutzer sehen die Kombination von e-Fahrzeugen mit dem öffentlichen Verkehr als wichtig an. Eine Mobilitätskarte, die eine Nutzung von Flinkster, Call a Bike und ÖPNV ermöglichte, wurde im Feldtest positiv bewertet. (Kapitel 6) Akzeptanz: Hohe Kundenbindung, aber geringe Nutzung Die Testnutzer haben eine hohe emotionale Kundenbindung. Diese wurde aber im Regelfall nicht in eine entsprechend häufige Nutzung der Fahrzeuge umgesetzt. Vielnutzer beurteilten die Dienstleistung e-Carsharing signifikant besser als die große Gruppe der Wenignutzer. (Kapitel 7) Mobilitätstypen: Öko-Überzeugte und ÖV-Affine mit Potenzial Auf Basis des Mobilitätstypenansatzes wurde die Stichprobe der potenziellen e-Carsharing-Kunden in verschiedene Typen aufgeteilt. Die höchsten Potenziale ergaben sich bei den Typen „ökologisch überzeugte Radfahrer und Multimodale“ und „pragmatisch orientierte ÖV-Nutzer“. (Kapitel 8) / The BeMobility Project: Car-sharing with Electric Vehicles The aim of the project was the insertion of e-vehicles into a carsharing fleet and its subsequent integration with multi-modal public transport offerings. User-friendly urban mobility services were developed and evaluated under real-world conditions. The attractiveness of integrating e-vehicles into an existing car-sharing service was investigated. (Chapter 1) Methodology: Field Trials and Multi-Method Market Research Potential users and customers were interviewed before and during the field trials. In addition, methods such as “lead-user integration”, focus groups, as well as a general survey of user attitudes were chosen. (Chapter 2) Interested Users and Pilot Customers: Male, Highly-Educated, with an Affinity to Public Transport Potential users and customers generally belong to social groups A/B and can be considered ‘lead-in’ users. The survey of more than 500 users in 4 separate market research studies yielded important insights regarding user acceptance and the future spread of e-vehicles in car-sharing fleets. (Chapter 3) E-Vehicles: Positive Driving Experience but Range is Critical Some expectation of potential users from the pre-trial phase were met or even over-fulfilled. This is true in particular with regards to the driving experience associated with e- vehicles. However, the expectation of users with regard to batteries, charging and, specifically, the range of e-cars were not met. (Chapter 4) Pricing Expectations: Low Acceptance of Surcharges for eCar-Sharing There is very low user acceptance of premium pricing for e-vehicles even when they are deployed as part of a car-sharing service. There was some, but relatively low willingness to pay for additional electric mobility services amongst users. (Chapter 5) Smart Mobility Card: Positive User Response to Multi-Modal Services Offerings The users that were surveyed view the combination of e-vehicles with public transport as important. A smart mobility card, which integrated flat-rate access to the Flinkster e-car-sharing service, the Call-a-Bike service and public transport were positively evaluated in the field trials. (Chapter 6) User Acceptance: Emotional Affinity – Low-Frequency Service Use The test users displayed a strong emotional affinity to the mobility service offerings. Routine, high-frequency users judge the electric car-sharing services significantly more positive than the bigger group of low-frequency users. (Chapter 7) User Characteristics: Green Values and Public Transport Affinity Indicate Potential A sample of car-sharing clients was surveyed. The highest user potential was documented in user types “green-conscious cyclists and multi-modal users” and “pragmatic public transport users”. (Chapter 8)

De senaste åren har tekniska förutsättningar, ekonomiska behov och ökade miljöproblem lett till en utveckling bort från massbilism i många av OECD-länderna. Allt fler deltar allt oftare i att dela resurser som ett sätt att minska de allt ökande kostnader som det innebär att äga och driva ett privatfordon. Delningstjänster kan ses som ett ökat intresse för vår omvärld men kanske främst som något som förenklar och sänker de kostnader som starkt är kopplade till mobilitet. Allt fler urbana livsstilar gör sig helt enkelt oberoende av att kunna transporteras med bil, till fördel för alternativen.   Sett i skuggan av det utgör bildelning ett alternativ till att äga sitt fordon men ändå ha fortlöpande tillgång till mobilitet när den behövs. Bildelningstjänster eller bilpooler fungerar som ett komplement till de andra transportsätten som innefattas i det multimodala och effektiva transportsystemet, såsom gång, cykel, buss, spårvagn, tunnelbana, hyrbil et cetera. Där alla delar har sina inbyggda styrkor och svagheter. Generellt har forskning skett på makroskala med ett fokus på att ta reda på hur vi får bildelningstjänster att fungera mest effektivt. I och med detta finns relativt goda kunskaper om Vad som behöver göras så är nästa fråga Hur? Var och hur tjänster bör planeras och placeras samt hur vi får fler att använda sig av dessa. Mer kunskap kan fås i området då allt fler tar del av dessa tjänster och de går från att vara en obskyritet till att möjligen ta rollen som norm. Utöver det så kan bildelning som delningsresurs ha inverkan både på parkerings- och platsbehov och en allmänt mer effektiv resursanvändning. Planering påverkar utformningen och därför existerar också ett behov av att systematiskt utvärdera hur bildelning kan understödjas och begränsas av detta.   Målet med detta arbete är att undersöka vilka faktorer som driver på fortsatt utveckling av tjänsterna och i viss mån finna lösningar som kan utvecklas för svenska fall. Framförallt för att ge mer kunskap kring den självklara kopplingen mellan planering och utformningskrav. Genom att basera en komparativ analys från den breda kunskap som finns kring bildelningstjänster kan vi finna generella faktorer som kan hjälpa oss med avvägningar kring en studie av ett faktiskt planeringsproblem. Något som för svenska förhållanden både skiljer sig och liknar de problem som man möter på i andra länder. Ett nyligen färdigställt projekt i Malmö agerar som studium då detta projekt från början implementerade möjligheter att sänka kravet på antalet parkeringsplatser. Bildelning har detta fall systematiskt använts som ett planeringsverktyg. Att fortsatt kunna utveckla en modell för användning för svenska plantekniska förhållanden kan ha stor inverkan på hur effektiv bildelning kan bli och vilken roll det kan spela i ett mer effektivt transportsystem i framtiden. / In recent years, technological conditions, economic needs and increasing environmental problems has led to a trend away from mass motoring in many OECD countries. More and more people participate in sharing resources with each other as a way to reduce the ever increasing costs involved in owning and operating a private vehicle. Sharing services can be seen as an increased interest in the world around us, but perhaps primarily as something that simplifies and reduces the costs that are strongly linked with mobility. Urban lifestyles to a greater extent free themselves of using car based transportation to the advantage of the optional modes.   Carsharing is an alternative to owning your own vehicle while still having continuous access to mobility when needed. Carsharing services operate as a complement to other modes included in the multimodal and efficient transportation system, such as walking, cycling, bus, tram, subway, rental car, et cetera. Each mode has its own strengths and weaknesses. Generally, research has taken place at the macro scale with a focus on finding out how we get carsharing services to work most effectively. As the knowledge about What is a relatively known, we need to answer the question How? Where and how services should be planned and located, and how do we get more people to use them. More knowledge will be available in the research area when more people take part in these services, and the services go from being an obscurity to possibly take the role as the norm. In addition to this carsharing as a resource that can have an impact on both parking and space requirements and a generally more efficient use of resources. Planning affects the design in which carsharing operates, it is therefore interesting to systematically evaluate how carsharing services are supported and held back by this circumstance.   The goal of this work is to investigate the factors driving the continued development of sharing services and how these possibly can be designed for the Swedish market. Above all, this can provide knowledge about the obvious link between planning and design requirements. Basing a comparative analysis on broad knowledge about carsharing provides general factors which can work as considerations for a study of an actual planning problem. The Swedish condition is both similar and different to the problems encountered in other countries. A project recently completed in Malmo acts as the study of the thesis mainly due to the fact that carsharing services were implemented as a prerequisite to lower the number of parking places needed. Hence carsharing was systematically used as a planning tool. To further develop a model for use with the Swedish preconditions and planning procedures can have a major impact on how efficiently carsharing can be and what role it can play in a more efficient transport system in the future.

Sharing commodities such as vehicles and houses in exchange for a fee has become very popular in the recent years. Companies such as Uber and Airbnb are two examples where their users can rent their underutilized assets for a period of time. This approach relies in the need of a trusted and centralized third party service provider which introduces security and privacy risks. Specifically, users’ personal data can be collected and misused by the service provider while at the same time the system is more vulnerable to a Distributed Denial of Service attack. In this thesis, a protocol namely CarGo, is presented and aims to allow car owners to rent their cars in a decentralized, secure and private way. Furthermore, this thesis presents a Proof-of-Concept on the Ethereum, Arbitrum and Optimism blockchains where a Solidity smart contract is utilized for automatic execution of car booking and payment functionalities. The solution ensures security and privacy of the booking details and offers safeguards against malicious behavior. Furthermore, with the deployment of the smart contract in layer two blockchain solutions the transactional fees have been greatly reduced. / Delning av tillgångar som bilar och hus mot en avgift har blivit mycket populärt på senare år. Företag som Uber och Airbnb är två exempel där användarna kan hyra sina underutnyttjade tillgångar under en period. Denna approach bygger på behovet av en pålitlig och centraliserad tredjepartstjänsteleverantör, vilket innebär säkerhets- och integritetsrisker. Specifikt kan användarnas personliga data samlas in och missbrukas av tjänsteleverantören samtidigt som systemet är mer mottagligt för Distributed Denial of Service-attacker. I denna avhandling presenteras ett protokoll, nämligen CarGo, som syftar till att tillåta bilägare att hyra ut sina bilar på ett decentraliserat, säkert och privat sätt. Dessutom presenterar denna avhandling en Proof-of-Concept på Ethereum, Arbitrum och Optimism-blockchain där en Solidity smart contract används för automatisk utförande av bilbokning och betalningsfunktionalitet. Lösningen säkerställer säkerhet och integritet för bokningsdetaljerna och erbjuder skyddsåtgärder mot illvilligt beteende. Dessutom har med implementeringen av smart contract i layer two blockchain-lösningar transaktionsavgifterna reducerats betydligt.

Latin American cities are challenged by the effects of population growth and insufficient infrastructure. As a consequent, Informal Car Share (ICS) is increasingly filling the gap as a transportation choice for underserved populations. ICS is the use of private vehicles to provide transportation for a fare that is neither taxed nor regulated by any type of government. Although this practice contributes significantly to development and economic growth, it is often stigmatized as unreliable and inconsistent, and little is known about it. This research expands existing definitions of ICS, using cases from Quito, Ecuador, a mountain city located in the Andes region in South America. It does so by analyzing Quito's ICS perceived effectiveness and performance from its users and drivers, the disruptions this system faces in the communities in which it operates, and its resiliency to bounce back from those disruptions. Findings suggested that despite its informality, ICS works with fixed stops, schedules, routes and fares. This is similar to formal systems operated by the government. Users and drivers described ICS as reliable and consistent, and they all reported a positive experience with the service. Findings also suggested that Quito's ICS is disrupted by six natural and political disruptions that delay the ICS service for 10 to 40 minutes. However, ICS proved to be adaptable and able to circumvent disruptions to ensure passengers connectivity to the city. Lastly, findings suggested that ICS users and drivers developed eight adaptation strategies to circumvent disruptions. Those strategies have created a system that aligns with features of resilient urban systems from UN-Habitat. Expanding the current understanding of how ICS operates, as well as its resilience capacity, is the first step to understanding better the value these self-organized systems provide to cities. / Doctor of Philosophy / The population in Latin America's cities is increasing and cities have been unable to keep up with the infrastructure demands that growth has created. As a consequent, Informal Car Share (ICS) are self-organized systems that arose as a solution to fill the gap in the peripheral areas that government provided transportation have not addressed.

Since the beginning of the 21st Century, the world has seen the rapid development of the so-called "sharing economy" or collaborative consumption (Botsman, 2010). One of the first areas affected by the shared economy is vehicle ownership. With the emergence of several new providers of mobility services, such as Uber and car2go, there has been the promise of changes to the traditional way of owning and using a vehicle (Wong, Hensher, & Mulley, 2017). One potential consequence of shared mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing the amount of space dedicated to parking, including parking requirements for residential developments. This thesis aims to assess the extent to which new shared mobility services (specifically, carsharing, bikesharing, and ridehailing) and travel demand management strategies (especially parking requirements and transit pass availability) relate to vehicle ownership among residents of multifamily dwellings. To do this, we use a web-based survey targeted to residents of multifamily apartments from Portland, Oregon. With these data, we built a multinomial logistic of the number of the vehicles owned as a function of socio-demographics, built environment, parking supply, transit passes, and three forms of shared mobility services. Results suggest that there is a strong association between shared mobility use and car ownership. However, it is not as significant as the effects of income, household size, distance to work, transit pass ownership, or even parking availability. Carshare use was negatively associated with the number of household vehicles, suggesting that it may be a useful tool in reducing car ownership. For respondents with higher education and income levels, increased carshare use was associated with fewer cars. Ridehail use, however, was not as clearly associated with reducing vehicle ownership and the effect was much smaller than that of carsharing. Parking availability in the building also has a significant and positive association with vehicle ownership. In sites with no parking available, there is an increased chance of the household owning less than two or more vehicles. However, this effect seems to disappear with the increased use of shared mobility. For all income levels, monthly use of ridehail and carshare between two and three times may decrease the odds of owning two or more vehicles. The use of both options, relaxing parking requirements and shared mobility availability, seems the best strategy to reduce vehicle ownership. In the short term, it is an alternative to those residents that decide to get rid of one or all cars but still are not ready to give up using cars. For the long term, a new relationship with vehicle ownership can be built now for the younger generation.

As cidades inteligentes emergiram como uma alternativa no trato das dificuldades oriundas do crescimento populacional observado nas áreas urbanizadas. Entre as iniciativas propostas por essa nova abordagem nos espaços urbanos, destaca-se a mobilidade inteligente. Ela propõe o uso dos recursos tecnológicos a fim de aprimorar a experiência de deslocamento de pessoas e de cargas, objetivando melhorar a qualidade de vida dos cidadãos. Nesse contexto, ressalta-se a importância do compartilhamento de carros como uma das alternativas para reduzir os índices de congestionamento, a emissão de poluentes e a demanda por áreas de estacionamento; além disso, esse serviço promove a interação com outros modais de transporte e os hábitos mais saudáveis entre os indivíduos que os utilizam. Ao analisar os modelos de negócio das empresas que operam nesse mercado, notam-se diferentes modalidades: compartilhamento de carros (ida e volta), compartilhamento de carros (trecho único), compartilhamento de carros (P2P), compartilhamento de corridas e caronas, empresas de redes de transporte e serviços de táxi. Também é possível identificar estreita relação com o consumo colaborativo (também denominado economia compartilhada), fenômeno amplamente explorado a partir da década de 2000, que fomenta o uso ou acesso aos bens em detrimento da propriedade. Assim, os usuários de carros compartilhados podem utilizá-los sem a incidência das obrigações e dos custos fixos associados à posse desses bens. Ambos os paradigmas utilizam a Internet, as redes sociais, os sistemas de informação e os recursos tecnológicos para prover seus serviços e conectar os usuários, criando as chamadas plataformas multilaterais. Estas suportam a criação e a operação em espaços físicos ou virtuais, conectando diferentes grupos de usuários; assim, ao reduzir os custos e as dificuldades desses encontros, disponibiliza-se um ambiente favorável à realização das transações, ou seja, ao compartilhamento dos carros. Esta tese de doutorado aplicou a análise qualitativa comparativa (QCA), a técnica MSDO, a análise de conteúdo e a análise cruzada de casos aos modelos de negócio de 14 organizações que atuam no segmento de carros compartilhados com a finalidade de identificar e descrever como os componentes da mobilidade inteligente, do consumo colaborativo e das plataformas multilaterais foram incorporados nas operações dessas companhias por meio de estudos de caso múltiplos. Os resultados alcançados indicaram alguns fatores críticos do sucesso empresarial desses modelos de negócio, entre eles: a análise de dados massivos por intermédio de ferramentas de big data, a disponibilização de aplicativos para dispositivos móveis, a implementação dos recursos de segurança física e lógica para os usuários dos serviços de carros compartilhados, o estímulo à colaboração on-line e ao uso de redes sociais e a operação em um mercado regulamentado. Devido à causalidade assimétrica, também emergiram componentes associados ao insucesso, entre eles: a ausência do uso de ferramentas de big data para análise dos dados massivos dos usuários; a indisponibilidade de aplicativos para dispositivos móveis; os recursos ineficazes de segurança física e lógica; a adoção de estratégias inócuas ou ausentes para a resolução do problema de massa crítica nas plataformas multilaterais; a dificuldade na obtenção de recursos financeiros para realizar investimentos nos diferentes grupos de usuários e a operação em um mercado sem regulamentação. / Smart cities emerged as an alternative in dealing with the difficulties arising from population growth observed in urbanized areas. Among the initiatives proposed by this new approach in urban spaces, smart mobility stands out as an essential service for the operation of cities. It proposes the use of technological resources in order to improve the experience of moving people and cargo, aiming to improve the quality of life of citizens. In this context, the importance of car sharing is highlighted as one of the alternatives to reduce congestion rates, the emission of pollutants and the demand for parking areas; in addition, this service promotes interaction with other transport modes and healthier habits among the individuals who use it. When analyzing the business models of the companies that operate in this market, different modalities are observed: car sharing (round trip), car sharing (one way), car sharing (P2P), carpooling, transport network companies and taxi services. It is also possible to identify a close relationship with collaborative consumption (also called sharing economy), a phenomenon widely exploited since the last decade, which fosters the use or access to goods over property. Thus, users of shared cars can use them without the incidence of the obligations and the fixed costs associated with the possession of these goods. Both paradigms use the Internet, social networks, information systems and technological resources to provide their services and connect users, creating the so-called multisided platforms. These support operation in physical or virtual spaces, connecting different groups of users; thus, by reducing the costs and difficulties of these matches, a favorable environment is provided to carry out the transactions, that is, the car sharing. This PhD thesis applied the qualitative comparative analysis (QCA), the MSDO technique, content analysis and cross-case analysis to the business models of 14 organizations operating in the car sharing segment with the purpose of identifying and describing how the components of smart mobility, collaborative consumption and multisided platforms have been incorporated into the operations of these companies through multiple case studies. The results achieved indicated some critical success factors of these business models, among them: analyzing massive data through big data tools, making mobile applications available, implementing physical and logical security features for users of car sharing services, the stimulation of online collaboration and the use of social networks and the operation in a regulated market. Due to asymmetric causality, components associated with failure also emerged, among them: the absence of the use of big data tools to analyze the users\' massive data; the unavailability of mobile applications; inefficient physical and logical security features; the adoption of innocuous or absent strategies for solving the critical mass problem in multisided platforms; the difficulty in obtaining the financial resources to make investments in different groups of users and the operation in a market without regulation.

Obiettivo della tesi è l’esplorazione di aspetti della relazione tra consumatori eticamente orientati ed aziende, considerando molteplici manifestazioni di relazioni problematiche consumatori-impresa o dalla cui relazione scaturiscono modificazioni sociali e di mercato. Nel primo studio si è indagata la capacità trasformativa dei consumatori eticamente orientati organizzati in GAS (Gruppi di Acquisto Solidali) mediante l’engagement relazionale con le imprese. Attraverso un duplice livello di engagement, tra membri del gruppo e del gruppo con i fornitori, si determinano collaborazioni impresa-consumatori basate sui valori che spingono alla modificazione di meccanismi di mercato alternativi rispetto a quelli mainstream. Nel secondo studio si è indagata la relazione, talora problematica tra consumatori-cittadini etici e non nei confronti di business sostenibili, nel caso specifico la produzione di energia da biomassa. Nonostante il business sia considerato sostenibile, la relazione dei consumatori etici con tali business può risultare non lineare e generare comportamenti positivi o negativi dei consumatori-cittadini nei confronti della fonte energetica. Infine, adottando la prospettiva dell’impresa, si è esplorato come business sostenibili, nel caso specifico setting di ricerca sono i servizi di car sharing, sono in grado di modificare atteggiamenti e comportamenti degli utenti attraverso l’uso del servizio. / The dissertation aims at exploring multifaceted aspects of ethical consumers-organization relationships. It takes into consideration multiple manifestations of issues aroused by the relationship and the market transformations lead by said relationships. The first study explores the potential of collective ethical consumers grouped in Solidarity Purchasing Groups (GAS) engaged with organizations to cooperate in order to affect market mechanisms and determine ethical transformations. A collaboration enhanced at switching mainstream market mechanisms towards improving sustainability values based markets is established between the ethical consumers groups and producers. On the second study a questionable ethical and non ethical consumers relationship with sustainable businesses, specifically biomass energy producers, has been taken into consideration. Though being sustainable, the consumer-citizen relationship with the firm could lead both to positive and negative behaviours. The last research, stemming from a car sharing organization’s perspective, explores the potential of a sustainable business model to affect and modify towards sustainability features consumers’ attitudes and behaviours through the use of sustainable business model as the car sharing services.
