RES-direktivets implementering och integrering i svensk politik

RES-direktivet antogs av EU under 2009 i syfte att öka Europas totala andel förnybar energi till 20 procent. Sverige tilldelades en kvot på 49 procent och regeringen valde att höja målet till 50 procent. Vid ökad användning av förnybar energi kan målkonflikter uppstå. De förnybara resurserna kan exempelvis användas i andra syften vilket skapar konkurrens. Energiomställningen beskrivs som en intstitutionell utmaning som kräver politisk vilja och svåra avvägningar.

Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

Ekobyn, ett framtida koncept

Jönköping's municipality requested a diploma work witch would present the experiences, as arisen during the existence of the echo village Smeden.To recive information for the background, literature at the university library were searched at the database "Libris" with words like "echo village" and "ecological living".Data was retrieved from 28 questionnaires that were sent out to the inhabitants of the echo village Smeden. The questionnaires contained questions about experiences, opinions, ideas and thoughts about living in this echo village. The results were analyzed and presented by diagrams and tables and showed that the inhabitants where most unsatisfied with the sewer and the system of the toilet. In the opposite the inhabitants experienced that the remaining systems were in satisfactory and the majority of the inhabitants were very pleased with their living conditions.Conclusions of this study are that an echo village would be a suitable alternative to an ordinary living and that ecological living would be something that would work well even in the future. An important thing to remember is that the systems of the households must be easy for the inhabitants to maintain otherwise the environmental thinking would be in risk of failure if some don?t have the energy to manage this properly..

Upplevelser av beslutsprocesser inom den kommunala hemtjänsten

The aim of this thesis is to examine the properties of the municipalities in Sweden that influence the choice of being a certified Fairtrade city. The independent variables which are used in the statistical analysis are municipal governance, local tax rate, whether there is an university and/or university college in the municipality, average income and higher education in the municipality. The variables are examined by logistic regression. Since there are no statistical data on ethical procurement, this exogenous variable isn?t included in the regression.

Närliten blir stor : ett företag på väg ut på den globala marknaden

This is a study about a company in Norrköping, called Stadium AB, and its first steps into the global market. We have studied how the conditions of the company have changed during their expansion. This study is not written from the viewpoint of business economics, it is rather a study from a cultural and social studies perspective. The study deals with subjects such as the globalization of society, organizational theories and leadership. The empiric material consists of Stadium?s staff magazine Tracks, the company?s swedish homepage on the Internet and an interview with Sussi Calås-Jonsson, Chief of the Department of Information at Stadium AB.

Dygnsvariation av metanemission från en anlagd våtmark

The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.

Nutrient efficiency in Swedish dairy cows fed total mixed rations or partial mixed rations

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Energy from municipal solid waste in Chennai, India : a feasibility study

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

Förbifart Stockholm - En studie av beslutsprocessen och argumentationen för och emot

The Stockholm Bypass is an infrastructural project planned to be located west of Stockholm. This study investigates the argumentation concerning the project from different perspectives. The theoretical starting point is within Decision Theory. The main theories include Bounded Rationality, Kingdon's study of the political agenda and theory regarding venue shopping, framing and lobbying. The method chosen for this qualitative case study consists of both gathering data through semi-structured interviews and through documents provided by stakeholders and information available publically through archives and media.

Ekonomisk tillväxt och miljön : En undersökning av miljökuznetskurvan

De tidigare studierna som undersökt miljökuznetskurvan (EKC) för koldioxid-utsläpp, där de flesta urval baserats på OECD medlemsländer, har fått varierande resultat. Den här studien använder sig av både OECD medlemsländer och länder som inte är medlemmar i OECD. Urvalets data baseras på åren 1971-2010 för totalt 57 länder från runt om i världen. Resultaten visar tecken på ett inverterat U-format förhållande mellan koldioxidutsläpp och inkomstnivå, men att ett monotont stigande förhållande inte kan avfärdas. Enligt de uppskattade ekvationerna är inkomstnivån där utsläppen tenderar att minska lägre för hela urvalet än för både OECD-medlemsländerna och länderna som inte är medlemmar i OECD.

Att styra bilanvändning mot en hållbar utveckling. Om geografiska livsvillkor kontra offentliga ingrepps betydelse för bilanvändning.

Car usage is determined by several facts, e.g. living conditions determined by geographical matters. There is a political will to control car usage with different kinds of incentives since car usage generates environmental problems. This essay analyses the differences between car usage in urban areas as opposed to thinly populated areas in Sweden and their significance on governmental incentives. By using statistics differences in car ownership during ten years between thinly populated areas, areas in the countryside and urban areas is studied.

Att färdas i symbios : ett gång -och cykelstråk anpassat efter trafikanternas rörelsemönster och behov

The aim of this paper is to examine the layout of public spaces and its effect on human behavior with focus on the relation between pedestrians and cyclists movement patterns in a specific path. The study emanates from the security aspect of pedestrians and cyclists, and builds upon previous theories and empirical studies about perception, security, information design, environmental psychology and behavior. The result shows that individual behavior and movement pattern differs with age, purpose, physical- and other conditions, and layout of the surroundings. A design proposal for improved layout of a path and a node between different oncoming paths has been developed to aid the users? needs, where a separation of walkways and bike lanes forms zones of security for the purpose of better orientation and a better flow between the users..

"Osynliga orchidébarn" - Självskadebeteende hos ungdomar sett ur de professionellas perspektiv

The purpose of this study was to examine the professionals´ views concerning self-harm behaviour in adolescents they meet. We interviewed nine different professionals. Our questions were: What do the professionals believe are the reasons to self-harm? How do the professionals experience self esteem and identity in adolescents with self-harm behaviour? How do the professionals look at the self-harm behaviour from a gender perspective? How do the professionals think a diagnosis can affect adolescents with self-harm behaviour? In our responses we noticed beliefs about the cause as a combination of environmental relationships and the individual who is born with a certain vulnerability. The professionals believe that the adolescents have trouble finding their identity.
