Miljöanpassad offentlig upphandling: effektivt styrmedel mot koldioxidutsläpp? : En studie av kostnadseffektivitet, transaktionskostnader och teknisk utveckling

Green public procurement (GPP) can be used as an instrument to reduce carbon dioxide emissions, and consideration of environmental aspects within public procurement is becoming more common in Sweden and internationally. Two product groups that have been pointed out as especially important are transports and electricity, where the opportunities for public purchasers to reduce emissions are relatively large. This paper studies GPP which aims at reducing emissions, primarily of carbon dioxide, through environmental requirements within these two product groups. A theoretical analysis of cost-effectiveness, transaction costs and effects on technological development is performed, followed by a closer study of how these aspects appear in practice within GPP. The results indicate that a cost-effective allocation of reductions between the two product groups is most likely to be attained if the main part of emission reduction is achieved through environmental requirements on electricity. The cost for emission reduction within transports is relatively high, especially for heavy transports. For transportation services, more generally focused requirements on emission reductions could probably give greater environmental gains, but the existence of transaction costs steer the environmental requirements towards more technology specific types.

Risk- och sårbarhetsanalyser för smarta elnät

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

Sveriges hantering i praktik av EU:s regelverk om samordningen av medlemsländernas sociala trygghetssystem : En fallstudie av svenska offentliga instansers implementering och uppföljning

This essay analyses how Swedish authorities implement the EU regulations on the application of social security schemes and, more specifically, when it comes to health care and sickness benefits. The research is based on a survey and several interviews and aims to answer how the lower echelons of the hierarchy work towards the implementation, what are their working conditions and how the authorities evaluate and optimize the implementation process.The general conclusion of the study is that there are several flaws in the implementation process. The results have shown that there is a lack of resources as well as of tutoring and education amongst the actors. The complexity of the regulations does also seem to have influenced the process. Finally the results have shown that the public instances do not proceed to a systematic evaluation of the implementation process which has led to a bad communication between the different actors as well as to difficulties in improving the flaws in the implementation process..

Från diskurs till praktik? En studie om säkerhetiseringen av irreguljär migration och dess konsekvenser

This thesis discusses the theory of securitization in relation to the issue of irregularmigration, from EU level to national level. By using discourse analysis, the purpose isto explore whether the discourse leads to practice when it comes to nationalimplementation of EU debates on return policy. The material used in this workconsists of policy documents regarding the Return Directive from the EuropeanCommission as well as the Reva Project in Swedish migration policy. The mainobjective of the Reva Project is to make the process of returning irregular immigrantsmore effective and it has been strongly criticized, both by media and public opinion.The conclusion of this case study is that even if the security rhetoric may appearstronger on the EU level, the main elements of the security discourse are stillportrayed in the implementation on the national level. Based on this analysis we canmake the presumption that discourse develops into practice in the case of returnpolicy in the EU-member state relation..

LEED i Sverige och i byggprojektet Borgarfjord 3.

This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..

Hållbarhetsredovisning och media: en studie av Vattenfall ABs hållbarhetsredovisningar och medierapporteringen under en femårsperiod

Sustainability questions that concern the subjects of environmental and social aspects are increasing in today?s society, and therefore the sustainability report is a way for companies to show their work with sustainability development by working with a clear report and follow up. As the first country in the world, Sweden has decided, as from the financial year of 2008, that all governmental owned companies should present a sustainability report according to the guidelines of GRI. The aim of this essay was to identify and analyze actual events from a sustainability aspect for Vattenfall, from a medial perspective during the time period 2005-2009. We made a content analysis of one company?s sustainability reports during a time period of five years and we connected this to the medias reports of the company from the same period, to see if there were any connections between the subjects that media had elucidated.

Ekoturisten : En studie om kunskap, motiv och vanor gällande ekoturism

There are several man-made environmental problems in today?s society. Tourism gives a lot of people serenity, creates jobs and better social circumstances but also has a dark side, a dark side that is harming our environment. Mass tourism creates large amounts of harmful gasses through transportation of tourists, littering ends up in pollution and acidification and the list goes on. Ecotourism has during the latter part of the last decade been marketed as a counter pool to the harmful kind of tourism and offers connectedness to nature.

Rederiers hantering av nya miljökrav : En studie om Birka Cruises, Tallink Silja och Viking Lines arbete med ekonomisk och miljömässig hållbar utveckling

The purpose of this study is to examine how Viking Line, Tallink Silja and Birka Cruises work with economic and environmental sustainability, and also to see how they work with new environmental legislations. In 2015 a new environmental legislation will be introduced, by the name Sulphur directive. The Sulphur directive entails a reduction in Sulphur dioxide emissions from ships where the emissions cannot exceed 0,1 percent. There are three alternatives to achieve the new environmental legislation, the use of Marine Gas Oil, LNG or scrubbers. All three alternatives will lead to increasing costs for the shipping industry.

Ungdomars medvetenhet om säkerhetsrisker med bankverktyg

According to Nosti (2012) banks target youths to find new customers by giving them special offers such as debit cards from a relatively early age. However, Moschis and Churchill (1979) point out that age can affect the level of knowledge in the consumer. Therefore, this essay focuses on youths as consumers. Specifically, youths? awareness of security risks in using bank tools such as debit cards or internet banks was studied.

Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn

The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses  The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.

Om miljövär(l)den : En kritisk diskursanalytisk studie av miljöetik i styrdokument, förlagsläroböcker och sponsrade läromedel

The urgency of sustanible development is world-over issue. This essay focuses on the relations of enviromental ethics in the context of the Swedish upper secondary school and the subject of geography, by analysing different educational texts.The purpose of this essay is to reveal and identify discourses of enviromental ethics in curriculum documents; Lgr 11 and the plan- and the coursedocuments for the subject of geography, in educational publisher?s textbooks and in sponsored texts related to the subject of geography and finally to discuss potential consequences this might implicate for education. For this have the methodology of Norman Fairclough´s critical discourse theory, CDA, as well as a matrix of environmental ethics, based upon Mikael Stenmarks classifications of enviromental ethics, been used.In the Cirriculum, Lgr 11 and documents for the subject of Geography, and in the educational textbooks from ?Liber? and ?Gleerups?, are the environmental ethics of intergenerational anthropocentrism the dominant.
