Hållbarhet är ett brett begrepp som kan definieras på många olika sätt. I denna rapporten undersöks hållbarhet utifrån produktens perspektiv, med avseende på produktutvecklingsprocessen. Mer specifikt är det sättet som man arbetar och tar beslut på i produktutvecklingsprojekt med avseende på produktens hållbarhet som står i centrum. Två företag som sysslar med farkoster analyseras i rapporten, där det ena företaget arbetar med utveckling av vägfordon och det andra med komponenter till flygplansmotorer. Metodiken bakom arbetet består av en litteraturstudie samt en intervjustudie där två respondenter från respektive företag intervjuas med hjälp av en förberedd intervjuguide.  Resultatet av intervjustudien presenteras sedan, uppdelat i olika teman som är relaterade till hållbarhet. Dessa teman diskuteras sedan i relation till den teoretiska referensramen. Resultaten av rapporten var till stor del överensstämmande med litteraturstudien och då båda företagen är involverade med farkoster som använder fossila bränslen uppstod flera likheter i deras hållbarhetskravshantering. Ett exempel på detta är bland annat när i produktutvecklingsprocessen identifiering av hållbarhetskrav sker. Aspekter som beslutsprocessen, hanteringen, ansvaret och utvärderingen av hållbarhetskrav visade sig vara komplicerade, och även fast teorin gick att applicera på mycket var det inte ovanligt att frågor kring dessa områden inte hade något definit svar. För vidare forskning föreslås exempelvis en djupare analys av produktutveckling av produkter med lång livslängd och hur detta samspelar med hållbarhet för produkten. Även återkommande begrepp i rapporten som livscykelperspektiv är rekommenderade aspekter av hållbarhet för vidare forskning kring, då detta framstod som relativt nytt i respektive betraktat företag. / Sustainability is a broad concept that can be defined in many different ways. In this report sustainability is examined from the product's perspective, with respect to the product development process. Specifically, it is the way that companies work and make decisions in product development projects in regards to the product's sustainability that is the central subject. Two companies that work with vehicles were analyzed in the report, where the first company works with the development of road vehicles and the second company works with the development of components for jet engines. The method behind this report consists of a literature study and an interview study where two respondents from each company are interviewed with the help of a prepared interview guide. The results of the interview study were then presented, and divided into different categories related to sustainability. These  categories were then discussed in relation to the literature study. The results of the report were in large part in agreement with the literature study, and because both companies are involved in the development of different types of vehicles that use fossil fuel there were several similarities related to their sustainability requirement management. One example of this is the identification process of requirements and at what point identification occurs. Aspects such as decision making, the handling, the responsibility and evaluation of sustainability requirements proved to be complicated, and even though the established literature study was applicable it was common that questions regarding these topics did not have definite answers. For further research it is recommended that for example a deeper analysis of long product development cycles is made and how this relates to the sustainability work in the development process. Also, recurring terms as "life cycle assessment" are recommended for further research since this was something that was relatively new to both companies.

In recent years, sustainability has become more important for fast fashion companies to embrace. Partly because of climate change and partly because consumers’ demands are higher. To make a real difference, fast fashion companies need to communicate sustainability clearly, and consumers need to be receptive to this type of communication. Thereby, both fast fashion companies and consumers have responsibilities towards the environment. However, previous research shows that consumers lack comprehension of sustainability communication within the fast fashion industry. This leads to consumption of non-sustainable clothing items over sustainable clothing items. Based on the aforementioned, three main concepts were identified as pertinent to build upon, encompassing subconcepts. The main concepts are sustainability communication, consumer comprehension and purchasing decisions. The subconcepts are says what, to whom, motivation and engagement, word recognition, language comprehension, knowledge, intentions and action.  As previous research is scattered, this research is conducted to give a gathered understanding. The purpose of this research was to examine consumer comprehension of sustainability communication within the Swedish fast fashion industry. Additionally, considerable emphasis lay on purchasing decisions. To successfully do this, the primary data was collected through a pilot study and focus groups. More specifically, there were four focus groups with six participants in each.  The empirical findings, together with the literature review, concluded that consumers recognise environmental labels and designations but do not know what they stand for. Further, sustainability communication is placed in a positive category, despite lack of comprehension. The level of motivation and engagement is low, due to suspicions of greenwashing, among other things. Language comprehension was found to have no major impact on consumer comprehension of sustainability communication. Some felt that the communication should be concise and others felt that it should provide a broader perspective. Moreover, consumers notice the sustainability communication, however, they do not seek nor respond to it. These conclusions intend to create value for fast fashion companies.

This thesis attempts to formally connect the fields of sustainability and responsibility. It considers first the larger context of business sustainability and responsible leadership, and evaluates the value and need for a common transformative space for these fields and what such a space might look like. As such, the thesis investigates the relation between sustainability and responsibility from an organizational and personal development perspective. This developmental perspective emerges from research in the domain of business education and the role of business schools in terms of educating responsible leaders for a sustainable world. The research suggests a concrete approach, the ‘Collaboratory’ for such a common space of transformation and critically evaluates its effectiveness to develop responsible leaders. The key contribution of this thesis lies in the interconnection of two fast evolving fields of research: the development of responsible leadership and business sustainability, providing a model for practitioners and scholars to reflect on and debate the larger forces and dynamics at play. Most research to date has focused on considering personal and organizational transformation separately. On the one hand, research scholars have studied effective learning environments to enable responsible leadership, and on the other hand, we have studied if and how organizations can advance from their current mode of operations to become “truly sustainable”. The thesis contributes a model to describe the interdependency of these two, and proposes the ‘Collaboratory’ as a means to realize this interdependency in practice. Chapter 1 is a new article theorizing the whole argument; subsequent chapters are previously published articles in these inter-connected fields and addressing methods and approaches to connect personal and organization development, drawing from a body of literature that considers the human spirit in large social change; and using the ‘Collaboratory’ as an illustrative and timely example for such methods.
