The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection. This stresses a development towards production methods of renewable energy. Among the existing methods, biogas is presented as an attractive alternative.

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.

The purpose of this study is to make a close and critical scrutiny of the EU Lisbon Strategy and the assumption of `sustainable growth´. A basic question is to clarify what is meant by `sustainability´ in the economic and the environmental dimension respectively, and also, to analyse the meaning of `sustainable growth´. Secondly, I try to investigate the relationship between the economical and environmental dimensions of the strategy. Are the goals of the dimensions compatible and mutually supporting or are they conflicting? By illuminating these issues the study moves towards a final set of questions: What are the arguments that encourage or counteract the Lisbon assumption of `sustainable growth´? Is the European Union approaching `sustainable growth´ looking at different economical and ecological indicators? What are the prospects for the Lisbon Strategy as a way towards global `sustainable development´?.

Previous studies have shown that there exists a gap between purchase intention and behavior in consumption situations. This gap is especially prevalent for sustainable or green products and even more so in terms of sustainable apparel consumption. Therefore, the adoption of sustainable fashion remains low as fast fashion dominates the industry. A counter-movement for mass consumption - access-based consumption - has reached the apparel industry and in Sweden we see it in the form of clothing libraries. This qualitative thesis uses in-depth interviews to uncover the feelings of seven consumers towards the idea of accessing rather than owning their clothing as a more sustainable consumption form, factoring in the strong identity connection that we have to our clothes and how this affects their perceptions.

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.

Today's unsustainable resource use is influenced by many factors. One key factor isproduction methods and patterns. Trough change of production patterns enterprises can bepart of the solution to a more sustainable society. This case study has analyzed environmentalperformance of the printer company Edita Västra Aros Ltd (EVA), who has gained awards forits environmental work, and what driving forces they have had during this work. The survey isbased on a qualitative method and the collected data consists of documents and staffinterviews, which have been analyzed with content analysis.

In this study environmental work in the Swedish hotel chain "Scandic" is investigated. Earlier studies point out sustainability and different environmental certificate programs as essential for the housing sector to contribute to sustainable tourism. The purpose and willingness to fulfill such a mission has been investigated by interviewing central actors in the hotel chain. The result shows that there is a desire to be part of environmental certificate programs mainly for the reason to be part of the system and not for the benefit of nature. Sustainable development is understood as being environmentally friendly. Different solutions to adapt and being more environmentally friendly is discussed.

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.

Sustainable urban development is a concept that has become increasingly important as the urbanization continues and more and more challenges are focused to the cities.  The Swedish government and authorities regulates and sets goals for how a sustainable urban development is to be achieved. These laws and goals are vaguely defined, which leads to disputes between the actors about how the term should be interpreted. By examining Västermalms Strand, an urban development project in Stockholm, this study strives to describe how involved actors interpret the concept of sustainable urban development and what the consequences of this are for urban development in Stockholm from an ecological, social and economic perspective. A case study has been carried out where a document study and interviews have been conducted. The interviews were conducted with four key actors from the private and public sector.

Hidden away in the pristine landscape on the northeast shore of the Dominican Republic, the remote village of Miches is on the verge of shifting its economic resource base from traditional fishing into what could become an international model for sustainable tourism. The aim of this thesis was to produce a vision of a waterfront park near the center of the village; demonstrating concept-based landscape design that reflects the goals of sustainable development originating from the local incentive structure. A composite landscape analysis and design concept both served to inform and guide the design work, which was executed through model building, hand drawings, and production of a visual presentation in the format of an architectural competition entry. The design concept, All invited, signifies the distinction between the development that is about to take place in Miches and the otherwise common all-inclusive resorts, where tourists are set apart from the local community and spend most of their time within the fenced-off premises of the hotel. All invited also captures the typical Dominican hospitality, and mirrors the aspirations of turning Miches into a safe and welcoming place for visitors. The result is a public park design that is equally inviting local residents as it is to tourists, and where the unique qualities of the site are emphasized without being exploited.

The producers of grain in Sweden are facing a rough future. The competition is getting harder all the time, in Sweden, in EU and also from the ?world market?. The producers have to be more efficient and have to have bigger units. Many producers might have to look for new alternative production opportunities.

The subject field studied in this essay is environmental scanning. The aim of this study is to analyse how three public organizations within the subject field sustainable development work with their environmental scanning. Most organizations have to relate to their surroundings such as clients and competitors. Environmental scanning is another very important field that organizations have to relate to in their work. This essay has three questions in focus which are the following;How is the work with environmental scanning in the three organizations arranged?How does the work with environmental scanning differ in the three organizations?How important is environmental scanning for the subject field sustainable development?The study was carried out through four conducted interviews with key persons within the three organizations.

Several studies indicate that Swedish men consume more meat than women, more frequently appear in advertisements for meat and more often than women handle the grilling of meat. Production of meat is one of the largest contributors to greenhouse-gas emissions and thereby poses a challenge for ecological sustainability. Several Swedish politicians and authorities have argued that reduced meat consumption is necessary to prevent continued global climate change. To understand and change consumption patterns we need to understand the consumer. This essay uses textual analysis to examine how Swedish men through text and images in three cookbooks use preparation and consumption of meat to construct different masculinities.
