In our everyday life we are faced with many choices that have consequences on the environment. One of these is the food we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment. A large number of meals are served every day in the public sector, which makes it an important player in the consumer sector that could make a major difference for the environment..

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

Lokala investeringsprogram was a subsidy program which supported environmental reforms during the years 1998 to 2002. The subsidies were given to Swedish municipalities. Most of the evaluations of the subsidised projects have now been completed and included in a database. The purpose with this thesis is to analyse whether the instrument has been effective with respect to carbon dioxide reductions and costs. These calculations have focused on subsidy and cost efficiency. The analysis has been compared with a previous report called "LIP ur ett samhällsekonomiskt perspektiv". The result shows that the reduction cost for one kg CO2 has been almost one SEK, which is twice as high as the cost reported in a previous report, half a SEK.

In the last years people has become more aware of issues regarding corporate social responsibility. This has led to a more thorough control of big multinational companies, which are often held account of violating social, ethical and environmental values. The term most often used for this is corporate social responsibility (CSR). H&M is a Swedish multinational company and the concept of H&M is fashion to a low price. The material most often used in producing clothes is cotton.

The aim of this paper has been to investigate how accounting firms govern their organizations with regards to the complexity in the service that they offer. The service includes the general accounting tasks which through standardization can be cost efficient, the advisory services that entail flexibility, and the relationship with the customer which needs to be taken into consideration when delivering the financial reports. These three components are important but require different approaches when it comes to governing the organization. The conducted case study has shown that the accounting firms govern their organizations bureaucratically and mainly through behaviour and accounting controls. The advisory services demanded by customers are standardized, not analytical, and therefore do not require the firms to take flexibility into consideration.

Background: Today, It?s not uncommon that international companies and organizations have a higher turnover than the GDP of developing countries. Consequently, this may suggest that the choices companies make in the context of their business has a great potential to influence the world from an economic, but also from a social and environmental standpoint. From this the notion emerged that companies have a responsibility, referred to as Corporate Social Responsibility (CSR). A clear definition of the CSR concept is difficult to find, more than 37 different definitions has been identified.

Det råder delade meningar om hur den Europeiska unionen kommer att utvecklas i framtiden. Skeptiker menar att den kommer utvecklas i riktning mot en federation och undergräva medlemsstaternas suveränitet, medan andra menar att det europeiska samarbetet främst är en frihandelsförening. Syftet med min uppsats är att undersöka hur det inom EU:s institutioner resoneras kring frågor rörande EU:s framtida integration, samt kring frågor rörande demokrati. Det material jag analyserar är ett urval av EU-dokument, där jag med kvalitativ textanalys, utifrån ett teoretiskt ramverk bestående av tre stycken integrationsteorier, försöker förstå hur EU:s institutioner ser på unionens framtida integration samt frågor rörande demokrati. Resultatet av undersökningen gav en mångfacetterad bild av hur det resoneras kring dessa frågor på högsta EU-nivå.

Denna studie undersöker det tolkningsutrymme som kan komma att uppstå på grund av oklarheter i förfarandet vad gäller tillfälliga samarbetskonstellationer. Studien är en fallstudie av kvalitativ art och empirin har insamlats med hjälp av semistrukturerade intervjuer. Fallet består av en samarbetskonstellation och dess beslutsprocess inför en eventuell etablering av en dryport i kommunerna Bjuv och Åstorp. Studien påvisar att det finns oklarheter som har lett till ett tolkningsutrymme var i de olika aktörerna ges möjlighet till att behålla och utveckla sina egna tolkningar av det aktuella problemområdet. Detta har i sin tur lett till att aktörer som i konstellationens början kände sig tveksamma till projektet har ändrat uppfattning och fått en mer positiv syn på situationen.

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Detta är ett examensarbete inom textil produktutveckling som har sin grund hos uppdragsgivaren Bellaobastian. Syftet med rapporten är att ge en inblick i miljöarbetet i värdekedjan hos mindre konfektionsföretag, vilka svårigheter som kan förekomma och hur den hållbara utvecklingen kan effektiviseras. Vi vill ge mindre svenska konfektionsföretag råd och förslag om hur de kan uppnå en tillfredställande nivå på deras miljöarbete utan tillgång till enorma resurser.Vi har utfört intervjuer, litteraturstudier samt jämförelseanalyser mellan företagen H&M, ACNE och Lindex. Vid diskussion och analysarbetet var det tydligt att miljöarbete i värdekedjan är en komplex process och att det är flera aspekter som spelar in.Vi har kunnat identifiera åtgärder som företagen kan utföra i hopp om att uppnå en mer hållbar utveckling, både specifika som tex, materialval men även mer övergripande som att ändra sitt synsätt. Åtgärderna vi kunde påvisa kretsar kring:- Minska överkonsumtion och effektivisera resurssparandet- Minska koldioxidutsläppen- Använd miljöledningssystem och märkningar- Ändra företagets synsättEn av slutsatserna vi kunnat konstatera genom våra undersökningar är att det inte räcker med att åtgärda problemen.

This thesis aims to analyse relations between the risk of Francisella in endemic areas and environmental variables. The thesis also discusses relations between occurrences of Tularemia and meteorological factors. The analysis resulted in several significant models that explained the occurrence of Francisella. These models can however only be applied to the year 2004 since there were too few test performed the other years, therefore no comparisons could be made. Another conclusion was that the relative humidity was significally higher in the year 2003, the same year as the occurrences of Tularemia was at its peak. .

Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.

Sustainability work is something that is emphasized more and more. Corporate Social Responsibility, CSR, is discussed and the question of how much responsibility companies should really take is frequently in the news. Companies tend to ask themselves how much responsibility they should take. CSR is a common concept of companies environmental and social work and a concept we tend to see here and there in our modern society. CSR includes companies? social responsibilities, both in terms of carbon footprint, working conditions, social responsibility and more.

The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
