Miljöledningssystem i små företag : vilka hinder finns och hur kan förenklade miljöledningssystem överkomma dessa?
Humanity?s increasing consumption has resulted in an increasing use of resources and thus an increasing environmental impact. Hence, the environment has become an important political issue. The increasing demands from stakeholders on companies to "green" their products and work internally with environmental issues makes it more and more important for enterprises to address these issues. Small enterprises constitute the majority of all enterprises and therefore they have a significant impact on environmental problems.
I andra hand en studie av attraktiviteten hos boenden med hållbarhetsanspråk
There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.
Ekoturismens inverkan på miljömässiga attityder och beteenden : En kvalitativ studie om individers erfarenhet av valskådning

Communication during the process of Environmental Impact Assessment:
Interviews concerning three infrastructure projects
Environmental Impact Assessment (EIA) is a method to describe the possible impact of a planned project. The aim of such an assessment is to aid a sustainable development, by supplying a comprehensive basis for decision-making. Today there are many people working with EIA in different forms, representing both different interests within the community, as well as having different individual points of view. The proponent is responsible for the EIA, but it is of interest to study the relationship between the different participants who are involved in this process. The aim of this report is to study how the different disciplines involved have communicated with each other and amongst themselves, what characterises good communication, and if anything should be improved.
Varför miljöredovisning? : en undersökning av lastbilstransportbolag
Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.
Miljökemikaliers påverkan på isbjörnars (Ursus maritimus) reproduktion och hur dessa kemikalier når djuren
Environmental chemicals are transported to the Arctic through the air and oceans, once within the Arctic they spread through rivers, lakes and other watercourses. Polar bears and sledge dogs in-gest high concentrations of environmental chemicals since many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. The aim of this study is to describe how environmental chemicals spread in nature, how they reach the polar bears, and finally how they affect the animals reproduction, with reproductive hormones and genitals in focus. The animals are exposed to a cocktail effect which complicates the assessment of the chemicals impact on the reproduction. Studies show that the genitals can decrease in size or become malformed, sexual maturation can be affected and the reproductive hormones can be disturbed.
Förnybar energi ur ett kvinnligt och manligt perspektiv : En attitydundersökning med avseende på att kartlägga hur synen på fönybar energi påverkas av om individen är kvinna eller man
Abstract The extraction and usage of energy give rise to immense environmental problems which helps to accelerate climate change. Energy is an important resource for the community and there are a variety of different types of energy sources available, that are either classified as renewable or non-renewable energy sources. The usage of renewable energy sources cause less environmental impact than the usage of non-renewable energy, which in turn means that the energy?s strain on the environment is strongly affected by the type of energy source used.The aim of the study is to describe to what extent attitudes towards renewable energy are affected by whether the individual is male or female, by examining the hypothesis regarding how women have a closer connection to nature and to a larger extent shows on an pro-environmentally friendly behavior than men, and if it also can be detected on issues related to renewable energy and thus imply that women have a friendlier approach towards renewable energy than men. A number of ecofeminist believe that women have a stronger bond with the nature through her embodiment as a woman and by her maternal role, which according to previous research also leads to the fact that women shows on a more extensive environmental behavior.Through a qualitative research method in the form of semi-structured interviews has three female and three male respondents been asked questions with regards to the environment, individual responsibility and energy.
Klimatcertifiering av livsmedelsföretag : - En kvalitativ studie om vad som får företag att anta klimatmärkningen och vad det innebär
This essay is a study of the motives and driving forces affecting how a food producer looks at, and incorporates, an environmental-labeling and its impact on their organization and strategy. Driving forces and motivations is an important part of a business strategy and impacts its content and its expression. Sustainability can be part of the overall company strategy but could also define the entire company. This study has shown that the main motive for working with eco-labelling is a genuine interest in issues concerning sustainability. This creates an opportunity for the company to communicate their environmental policies to their customers. For a company that works proactive and innovative with sustainability and climate issues, the new climate framework does not mean any major organizational or strategic changes.When the framework is incorporated in the organization the farms need to be analyzed with a climate impact perspective. This essay shows that this process, together with tools developed to handle the framework, make change in the way dairy farmers think and how they relate to their daily work..
Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie
The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

Scanias arbete med miljöledningssystem : faktorer som motiverar medarbetarna
Societal expectations of responsible corporate conduct are currently a fact. It is manifested ina corporate need for limiting and managing external effects, such as environmental impact.An environmental management system is a tool for organizations to structure theirenvironmental work and increase their efficiency. Managing the corporate operations toaccommodate to environmental objectives requires an organizational understanding of theobjectives as well as the procedures. A condition for a successful implementation is the coworkers´ willingness to participate and collaborate.A study made on the co-workers attitude towards the ISO 9000 standard (i.e. qualitymanagement system) reveals that the earlier positive findings are not completely true.

Utveckling av analysverktyg för verksamheters CO2-utsläpp och energianvändning
With increasing energy prices and increased focus on the environment we saw the need for companies to get control over their energy use and their emission of carbon dioxid. An analysis tool that integrates both these areas is, with our knowledge, not available on the market today. Therefore, our project became to develop such a tool.By doing this degree project we would like to clarify that energy consumption and environmental impact are integrated. The less energy consumed by today?s society the smaller the environmental impact will be.
