The aim of this study is to understand the Fair Trade Coffee Business Model by determining how the Fair Trade Coffee Business Model affects the livelihoods of the small scale producers in developing countries. The Fair Trade Coffee Business Model is driven by the mission to improve the well-being of the small scale producers located in developing countries through the lens of the Triple Bottom Line (economic, social and environment). What is the significance of fair trade coffee to the economies of developing countries that produce coffee? The economies are considerably impacted by coffee production as coffee ranks as the second foremost exported commodity from developing countries (European Coffee Federation, 2006). Ensuring the small scale producers receive a fair price for the coffee they grow is only one of the initiatives of the model. Other key initiatives include pre-harvest financing, increased healthcare services, working together for a higher quality coffee, fairer business conduct, improvements in education, and technical assistance. The findings of this study provide some insights into the Fair Trade Coffee Business Model’s effect on the livelihoods of the small scale producers in developing countries through the lens of the Triple Bottom Line. The Fair Trade Coffee Business Model has increased the quality of the coffee bean produced by the small scale producers along with developing long term business relationships throughout the Fair Trade Coffee Business Model supply chain. In sum, the small scale producers reported that the Fair Trade Coffee Business Model has a positive effect on their livelihood and well-being. More specifically, they also indicated that the motivations for them to participate in the Fair Trade Coffee Business Model are receiving a better price for coffee, democratic decision making and farm training. An additional finding affirms that the Fair Trade Coffee Business Model is a sound contributor to the socio-economic stability of the small scale producers, offering a sustainable income-generating alternative market strategy.

This thesis addresses two research objectives: i).empirically develop a taxonomy based on firms strategic Corporate Sustainable Development (CSD) orientation to better understand and describe their characteristics and business differentials; and ii).develop and empirically test an integrated framework of antecedents and consequences of the strategic CSD, including pathways and contingencies. The full study involves two consecutive steps: a qualitative study using in-depth interviews with senior marketing executives/experts from eight selected organisations; and a quantitative inquiry using an online survey, with a final sample of 183 medium to large Australian companies across manufacturing, mining and utilities/energy industries. Collectively, this two-stage study yields interesting research findings that are of substantial academic and managerial value as follows: The taxonomy analysis identifies three distinct groups: Strategic Achievers, Risk Avoiders and Suspicious Observers, that represent the three levels/stages of CSD adoption from high to low. These three clusters are described by what they do, why they do it, the major barriers and performance differentials. These findings contribute to the classification scheme and may assist managers to determine current levels of CSD, identify possible business opportunities and/or decide on the strategies of CSD adoption. Through developing CSD measures and testing the relationships within the proposed framework, Innovation Capability (IC) is found to be a pathway (mediator) for firms to gain competitive advantage from Corporate Sustainable Development, whereas CSD does not impact on Business Performance directly when IC is absent. This inconsistent mediating effect of IC provides interesting new insight. In addition, CSD exhibits a positive impact on firms Member Organisation Identification, a surrogate measure of corporate reputation from the perspective of employees. As part of the second research objective, this study also conducts the first empirical testing of the Menon and Menon (1997) model, and found that Industry Reputation moderated the Enviropreneurial Marketing and Business Performance relationship. These findings provide new knowledge concerning strategic Corporate Sustainable Development (CSD) orientation as well as the underlying mechanisms, which may inform managers with viable directions for integrating corporate economic benefits with social and environmental considerations.

This diploma thesis, in practical part, evaluates general opinions about CSR in SMEs, it estimates the level of perception of attitudes to demonstrations, motives, barriers and stakeholders SMEs when using CSR and it evaluates realized responsible activity MSP. Subsequently evaluates the perception of the factors influencing the CSR concept level and realized SMEs responsible activity using composite indicators. At the base of analysis results we formulate the recommendations for the support of implementation of CSR in SMEs.

Os temas desenvolvimento sustentável e sustentabilidade vem norteando inúmeras discussões e debates, tanto no meio acadêmico como empresarial, em função da importância reconhecida pela sociedade da abordagem de questões ambientais, sociais e econômicas ou, em muitos casos, avaliações que vão além destas dimensões. O setor agropecuário, incluindo a suinocultura, por fazer uso de recursos naturais, coloca o foco das pesquisas do setor na dimensão ambiental, mas uma análise integrada e interrelacionada de todas as dimensões mostra-se necessária. A necessidade de criação de uma metodologia própria, acessível e composta por indicadores de desempenho específicos, que integrem as três dimensões propostas pelo Triple Bottom Line e baseada na percepção dos produtores para avaliação da suinocultura de terminação, desencadeou a motivação para a presente pesquisa. Construíram-se indicadores de desempenho abrangendo as dimensões social, ambiental e econômica, a fim de adaptar a metodologia M.A.I.S. (Método de Avaliação de Indicadores de sustentabilidade organizacional) para a suinocultura de terminação, em sistemas integrados de produção. Visando validar a ferramenta construída, esta metodologia foi avaliada por meio de uma pesquisa survey junto a 31 propriedades familiares do município de Aratiba (RS), detentor do maior rebanho suíno do Estado do Rio Grande do Sul no ano de 2011. Através deste estudo, foi conferido ao município o status de “em equilíbrio”, apesar da identificação de indicadores classificados como “em desequilíbrio” dentro das três dimensões propostas. O método permitiu, além da classificação, a visualização dos pontos críticos identificados em cada dimensão e em cada sistema produtivo do município amostrado. A aplicação da ferramenta também apontou limitações na construção de alguns indicadores, comprometendo a eficácia e validação do método como um todo. Porém, a análise indissociada e inter-relacionada dos indicadores e das dimensões, permitiu a identificação de pontos crítico que podem nortear o embasamento estratégico de ações públicas e privadas, a fim de contribuir com o desenvolvimento do setor. / The themes sustainable development and sustainability have guided countless discussions and debates in both academic and business circles. This is a direct result of the importance placed on society´s approach to environmental, social and economic issues and, in many cases, evaluations that go beyond these dimensions. The focus of the research has been on the environmental dimension, but an integrated and interrelated analysis of all dimensions is shown to be necessary. The motivation for this research was triggered by the need to create a methodology based on producer´s perception to evaluate finishing pig systems. The methodology needed to be specific to this area, accessible and composed of performance indicators which integrate the three dimensions proposed by Triple Bottom Line. Performance indicators were established encompassing social, environmental and economic dimensions to adapt M.A.I.S. methodology (Method of Evaluation of Organizational Sustainable Indicators) to swine termination in integrated systems of production. The methodology was validated through survey research applied in 2011 to 31 family properties in the rural area of the city of Aratiba, a region with the largest concentration of swine herds in the state of Rio Grande do Sul. As a result of the study, the region was granted the status of “balanced” despite the identification of unbalanced indicators within the three proposed dimensions. In addition to the classification, the method allowed for the visualization of critical points shown inside each dimension and each productive system of the sample properties. The application tool revealed limitations in the construction of some indicators, compromising effectiveness and validation of the method as a whole. However, the undissociated and interrelated analysis of indicators and dimensions allowed for the identification of some critical points that can guide the strategic foundation of public and private actions in order to contribute to the development of the sector.

Abstract Today's society is developing towards a more conscious and dedicated attitude concerning the need for sustainable businesses. To ensure that the construction business who is responsible for massive impacts to environment and the society, the legislation demanding sustainability reporting has been passed in the EU. The purpose of this legislation is to force companies to include the environmental and social aspects of their operations and not just the economic. The purpose of this study is therefore to investigate how the construction companies in Sweden has been affected due to the legislation on sustainability reporting. The aim of this study is, through a qualitative working method, to answer which governing instruments the construction companies use in order to implement sustainability in the entire organisation on a day to day basis. The study has investigated four construction companies largely based in and around the three biggest cities in Sweden, Stockholm, Gothenburg and Malmö. The interviewees in each company has a role in which they are involved in the strategic operations towards sustainability. The aim is here for the study to answer which governing instruments has been the most influential and successful. The results of the study reveals that beyond the legislation each company has a very different approach and layout concerning the sustainability reporting. The reason for this is because each company has different guidelines through frameworks and certification standards. Depending on what they consider to be vital elements to report, the reportings differ leading to different forms of governing throughout the companies. This also shows that the most successful governing instruments differ as well. Although the study concludes that the companies have mutual governing instruments in the form of education for the employees to enhance competence. It also shows that they all use instruments impacting employee values which leads to a comprehensible understanding of the company’s visions and guidelines.

Background: Sustainability is a growing trend which companies should acknowledge and incorporate. The role HR can be a direct contributor in the integration of sustainability. SMEs’ characteristics can facilitate the implementation of sustainability, which can be a source of competitive advantage.   Purpose: To examine the integration of sustainability through HR practices in SMEs, in the Jönköping region.   Method: An exploratory and an abductive approach were used to fulfill the purpose of the thesis. The explanation building strategy was used to analyze the data. Theories from the literature were compared with the empirical findings to identify patterns, based on the categories within the HR practices. The empirical data followed a qualitative method and was based on a multiple-case study, consisting of ten interviews with SMEs.   Main findings: SMEs in the Jönköping region had a high level of understanding in terms of sustainability. The HR practices were utilized for a better integration of sustainability. Incorporating sustainability in the firm’s values was the most effective way. This was achieved through integrating sustainability in the different HR practices; by communicating its value to employees, emphasizing it during the recruitment to assure value alignment, as well as explaining it during training activities.   Managerial implications: The findings showed that managers could benefit from considering the suggested HR practices for the integration of sustainability. As a result, other regions in Sweden can take advantage and learn from the case of the Jönköping region.

The purpose of this study was to explore users' and preparers' perception of sustainability reporting, especially for accountants and financial analysts who are involved with the Global Reporting Initiative (GRI) Sustainability Reporting Guidelines and GRI based sustainability or CSR reports in the United States. With the increasing trends to sustainability and corporate social responsibility (CSR), it is important to understand what level users and preparers currently hold towards the sustainability reporting. This study used samples from the following resources: all companies included in the GRI report list as a report preparer group and financial analysts as report users, whose companies' core business focused on social and environmental investing. This study examined four hypotheses concerning general corporate sustainability & reporting and sustainability performance indicators in environmental, economic and social aspects suggested by the GRI Guidelines. This paper contributes to corporate social responsibility and sustainability reporting. This paper studied users' perception of sustainability reporting and corporate social responsibility (CSR). Prior research mainly focused on preparers' perception or attitudes toward sustainability reports (Guthrie & Parker, 1990; Kolk, 2004; Lindgreen et al., 2009; White, 2005). Also, this paper adds to the literature on Global Reporting Initiative (GRI) and its guidelines that have not been extensively studied in prior research. The results revealed that users and preparers agreed on the important issues asked for the general corporate sustainability and reporting, and both groups held similar attitudes towards the environmental, economic and social performance indicators and felt most of them as important to be included in a sustainability report. In addition, both groups indicated the GRI as the preferred standard setting body for sustainability reporting and gave support to GRI for its effort to establish and promote the standards for sustainability reporting. Finally, a considerable number of users and preparers agreed that the GRI report can fairly measure a company's environmental, economic and social performance.

[EN] The choosing of an adequate structural typology for a building in its design stage is a complex problem due to different tangible and intangible factors and the multiple alternatives that exist. Nowadays sustainability, defined by triple bottom line englobing economic, social and environmental criteria, gains more and more relevance. However, in the construction sector, companies keep applying tools based on traditional bottom line referenced to one metric (financial performance or cost), to evaluate projects, ignoring, or underestimating, environmental or social values and forgetting about long-term impact on quality life of present and future generations. Moreover technological advances allow the development of new industrial solutions with a higher productivity rate and a lower impact, but construction is a sector that struggles to innovate and traditional solutions are still often applied without considering the solutions provided by industry. Multicriteria methods are being set higher each day as key tools, capable of incorporating environmental and social matters to the decision- making process. Tools using multicriteria evaluation to assess sustainability of finished buildings and sustainability of a certain type of structures already exist. The objective of this thesis is to develop a hybrid method of multiple criteria, combining AHP with the Delphi method and the VIKOR technique, to apply economic, social and environmental criteria in the selection of a structural typology for medium spanned buildings, taking into account both the construction and the operation stages. Using AHP, a hierarchical structure is defined from judgements emitted by a panel of experts, with the following levels: goal, criteria, sub-criteria and alternatives. From this hierarchy, also following AHP and with the judgements emitted by the panel of experts, a priority vector of the sub-criteria with respect to the goal and the priority vectors' matrix of the alternatives with respect to each sub-criterion are obtained. The Delphi technique is used in order to handle the surveys in which experts emit their judgements, until consensus is reached. From the priority vectors, applying the VIKOR method, the compromise solution is reached, being this the closest to ideal. For the elaboration of this tool, tangible criteria, like manufacturing cost, transport and assembly cost, emissions impact and embodied energy and operating energy; and intangible criteria like roof maintenance cost, aesthetic, satisfactory fireproofing and the use of local materials, have been considered. The specific case of a 17 m span sports hall in a recreational level has been studied. Five alternatives have been evaluated: both of the traditional Prefabricated concrete and purlins and Steel lattice and purlins options and other three applying technological innovations developed by the building industry: Prefabricated concrete and self-supporting curved system, Self-supporting curved system and Laminated wood and purlins, being the Self-supporting curved system roof option obtained as the optimal solution. Lastly, a computer tool is designed in which, for any medium spanned building, introducing data from companies offering the five studied alternatives, a compromise solution is obtained, taking into account sustainability criteria. The developed tool will serve as help towards the choosing of a structural typology, applying sustainability criteria for the roof a medium spanned building. / [ES] La selección de una tipología estructural adecuada para un edificio en la etapa de diseño es un problema complejo, debido a los diferentes factores tangibles e intangibles y a las múltiples alternativas que existen. Hoy en día la sostenibilidad, definida por el triple principio, que engloba criterios económicos, sociales y ambientales, es cada vez más relevante. Sin embargo, en el sector de la construcción las empresas siguen aplicando herramientas basadas en análisis de costes y beneficios para evaluar proyectos, ignorando o subestimando valores medioambientales o sociales y olvidando el impacto a largo plazo sobre la calidad de vida de las generaciones presentes y futuras. Además, los avances tecnológicos han permitido el desarrollo de nuevas soluciones industriales con una mayor productividad y un menor impacto, pero la construcción es un sector al que le cuesta innovar y a menudo se siguen aplicando soluciones tradicionales sin considerar las distintas soluciones proporcionadas por la industria. Los métodos multicriterio se están posicionando cada vez más como herramientas clave, capaces de incorporar cuestiones medioambientales y sociales en el proceso de toma de decisiones. Ya existen herramientas que utilizan métodos de evaluación multicriterio para evaluar la sostenibilidad de los edificios terminados y la sostenibilidad de las estructuras de un tipo determinado, comparándolas con las mejores técnicas disponibles. El objetivo de esta tesis es desarrollar un modelo híbrido de criterios múltiples, que combina el AHP con el método Delphi y la técnica VIKOR, para aplicar criterios económicos, sociales y ambientales en la selección de una tipología estructural para edificios de luces medias, teniendo en cuenta tanto la etapa de construcción como la de funcionamiento. Utilizando AHP se define una estructura jerárquica, a partir de juicios emitidos por un panel de expertos, con los siguientes niveles: objetivo, criterios, sub-criterios y alternativas. A partir de esta jerarquía, siguiendo también el AHP y con los juicios emitidos por el panel de expertos, se obtiene el vector de prioridad de los sub-criterios respecto del objetivo y la matriz de vectores de prioridad de las alternativas respecto de cada criterio. Para gestionar las encuestas en las que los expertos emiten sus juicios, hasta alcanzar el consenso, se utiliza la técnica Delphi. A partir de los vectores de prioridad, aplicando el método VIKOR, se obtiene la solución de consenso, que es la más cercana a la ideal. Para la elaboración de esta herramienta se han considerado criterios tangibles como el coste de fabricación y el de transporte y montaje, el impacto de las emisiones y las energías interna y de funcionamiento y criterios intangibles como el coste de mantenimiento de la cubierta, el aspecto estético, la resistencia al fuego y el uso de materiales locales. Se ha estudiado el caso concreto de un pabellón polideportivo de 17 m de luz, evaluando cinco alternativas: las dos tradicionales de vigas celosía y correas metálicas y vigas y correas prefabricadas de hormigón pretensado y otras tres que aplican las innovaciones tecnológicas desarrolladas por la industria de la construcción: vigas de hormigón prefabricado con cubierta tipo membrana, cubierta metálica autoportante y estructura de madera laminada, obteniéndose como solución óptima la cubierta metálica autoportante. Por último, se diseña una herramienta informática en la que, para cualquier edificio con una luz media, introduciendo datos obtenidos de ofertas de empresas de las cinco alternativas estudiadas, se obtiene la solución de consenso teniendo en cuenta criterios de sostenibilidad. La herramienta desarrollada mediante hojas de cálculo servirá de ayuda para elegir una tipología estructural, aplicando criterios de sostenibilidad, para la cubierta de un edificio con una luz media. / [CAT] La selecció d'una tipologia estructural adequada per a un edifici en l'etapa de disseny és un problema complex, a causa dels diferents factors tangibles i intangibles i a les múltiples alternatives que existeixen. Avui dia la sostenibilitat, definida pel triple principi, que engloba criteris econòmics, socials i ambientals, és cada vegada més rellevant. No obstant açò, en el sector de la construcció les empreses segueixen aplicant eines basades en anàlisis de costos i beneficis per a avaluar projectes, ignorant o subestimant valors mediambientals o socials i oblidant l'impacte a llarg termini sobre la qualitat de vida de les generacions presents i futures. A més, els avanços tecnològics han permès el desenvolupament de noves solucions industrials amb una major productivitat i un menor impacte, però la construcció és un sector al que li costa innovar i sovint se segueixen aplicant solucions tradicionals sense considerar les diferents solucions proporcionades per la indústria. Els mètodes multicriterio s'estan posicionant cada vegada més com a eines clau, capaces d'incorporar qüestions mediambientals i socials en el procés de presa de decisions. Ja existeixen eines que utilitzen mètodes d'avaluació multicriterio per a avaluar la sostenibilitat dels edificis acabats i la sostenibilitat de les estructures d'un tipus determinat, comparant-les amb les millors tècniques disponibles. L'objectiu d'aquesta tesi és desenvolupar un model híbrid de criteris múltiples, que combina el AHP amb el mètode Delphi i la tècnica VIKOR, per a aplicar criteris econòmics, socials i ambientals en la selecció d'una tipologia estructural per a edificis de llums mitjanes, tenint en compte tant l'etapa de construcció com la de funcionament. Utilitzant AHP es defineix una estructura jeràrquica, a partir de judicis emesos per un panell d'experts, amb els següents nivells: objectiu, criteris, sub-criteris i alternatives. A partir d'aquesta jerarquia, seguint també el**AHP i amb els judicis emesos pel panell d'experts, s'obté el vector de prioritat dels sub-criteris respecte de l'objectiu i la matriu de vectors de prioritat de les alternatives respecte de cada criteri. Per a gestionar les enquestes en les quals els experts emeten els seus judicis, fins a aconseguir el consens, s'utilitza la tècnica Delphi. A partir dels vectors de prioritat, aplicant el mètode**VIKOR, s'obté la solució de compromís, que és la més propera a la ideal. Per a l'elaboració d'aquesta eina s'han considerat criteris tangibles com el cost de fabricació i el de transport i muntatge, l'impacte de les emissions i les energies interna i de funcionament i criteris intangibles com el cost de manteniment de la coberta, l'aspecte estètic, la resistència al foc i l'ús de materials locals. S'ha estudiat el cas concret d'un pavelló poliesportiu de 17 m de llum, avaluant cinc alternatives: les dos tradicionals de bigues gelosia i corretges metàl·liques i bigues i corretges prefabricades de formigó pretesat i altres tres que apliquen les innovacions tecnològiques desenvolupades per la indústria de la construcció: bigues de formigó prefabricat amb coberta tipus membrana, coberta metàl·lica autoportant i estructura de fusta laminada, obtenint-se com a solució òptima la coberta metàl·lica autoportant. Finalment, es dissenya una ferramenta informàtica en la qual, per a qualsevol edifici amb una llum mitjana, introduint dades obtingudes d'ofertes d'empreses de les cinc alternatives estudiades, s'obté la solució de compromís tenint en compte criteris de sostenibilitat. La ferramenta desenvolupada servirà d'ajuda per a triar una tipologia estructural, aplicant criteris de sostenibilitat, per a la coberta d'un edifici amb una llum mitjana. / Martínez García, MP.
