Att möta utmaningen - En diskursanalys av europeiska staters inställningar till utsläppsreduktioner

The European Union is a self proclaimed leader in the field of climate change and has a common target for reductions of greenhouse gas emissions. In spite of this, there are great differences between the member states capacity and dedication to the cause of implementing the Unions climate policy and reduce their emissions. The purpose of this thesis is to contribute to an understanding of how different European states construct their identity in the context of climate change mitigation. By analyzing national documents from three European states and using tools deriving from discourse analysis, I aim to illuminate differences and similarities in their rhetoric. The result is that due to the states relationship to the European Union and the United Nations, there are great similarities in the way they construct mitigation and their identity.

Hållbar stadsutveckling? : Problem och målkonflikter i planeringen av Hagastaden och Norra Djurgårdsstaden i Stockholm

The major environmental problems that we have today are frequently mentioned in the media today. One example is the ongoing debate regarding global warming and its causes and consequences. There are also several other problems in our society such as segregation and social tensions. Most agree that we must do something to solve these problems and that we must try to achieve a sustainable development for the entire planet. But how should it actually be done and what trade-offs, compromises, sacrifices and changes must be made?The purpose of this paper is to examine how these issues are being dealt with in Swedish city planning.

Högfrekventa tryckvariationer under de senaste århundradena

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.

Klimat & Patriarkat : Genusgeografi i Huddinge

The essay deals with gender aspects on climate change adaption. The aspects consist of the fact that women in Sweden drive cars less than men, and that women in the developing world are more affected by natural disasters arising from global warming. This study was carried out in the municipality of Huddinge, a suburb to Stockholm, by interviewing one Agenda 21 coordinator, one planner and one student in genderstudies. I also attended a meeting in the Committee for built environment in the Huddinge Municipality, to ask the politicians questions and observe gender structures during the meeting. The results also consist of a search for gender-related words in the documents used in the essay.The results are analysed using ecofeminsim, a theory that connects woman subordination and environmental destruction.

SecRePac - Strimlare för hushållsförpackningar

SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.

Dendroklimatologisk analys av lokalklimat vid Grövelsjön i Dalafjällen

Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation.  In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.

Är införande av EU ETS en lösning av miljöproblemet växthuseffekten? - en analys ur ett ekonomiskt perspektiv

Uppsatsens syfte är att analysera om och i så fall hur införandet av en marknad för utsläppsrätter, EU ETS, The European Union Greenhouse Gas Emission Trading Scheme, är en effektiv åtgärd för att åtgärda externalitetsproblemet växthuseffekten. Uppsatsens slutsatser är att införande av EU ETS medför större samhällsekonomisk vinst än om EU ETS ej införts. Nuvarande utformning av EU ETS omfattar inte alla verksamheter som bidrar med utsläpp av växthusgaser och måste därför kompletteras med andra styrmedel för att uppnå reduktionsmålet. EU ETS kan bli ett effektivare styrmedel om fler sektorer omfattas i handeln, exempelvis transportsektorn som i Sverige är den sektor som förväntas öka sina utsläpp. Handelsystemet kan även effektiviseras genom att tilldelningen av utsläppsrätter sker via försäljning istället för att vara gratis.

Vill EU vända på steken? : En kritisk analys av EU-kommissionens ställningstagande i frågan om animalieproduktionens klimatpåverkan

This thesis examines the ongoing European political debate on the links between livestock production and climate change. In the end of 2006 the UN Food and Agriculture Organization (FAO) released their report Livestock?s long shadow, showing that livestock production represents some 18 % of the total global greenhouse gas emissions. The purpose of this paper is to explore the European Commission?s position and response to this question since the release of the report.Using Arne Naess? argumentation analysis, statements made by the Commission will be systematically organized and broken apart.

Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel

Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol. Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.

Förutsättningar för småskalig solelproduktion i Australien

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

Höjdförändringar på Lomonosovfonna, Svalbard, 1996-2012

The climate changes and the global warming have a great impact on the Arctic environments. This partially depends on that the albedo is getting lower when snow and ice is melting and exposes more and more dark surfaces of the land and sea. This leads to a feedback effect; the melting accelerates because dark surfaces attract more sun radiation. Because of the heating the glaciers in Arctic retreat. The purpose of this report is to obtain an eventual change in elevation on the glacier Lomonosovfonna that is located on Svalbard by comparing elevation data collected by NASA and GPS data from 1996-2012.

Miljöpåverkan av äggproduktion : En jämförelse mellan Lilluns ägg och andra svenska äggproducenter

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.

Hållbar konsumtion av nötkött och mjölk

Sustainable beef and milk consumption. The consumption of beef and dairy products in Sweden is high. A lot of greenhouse gases are emitted from the production of these products. The production of beef in Sweden has decreased but the import has increased. The number of dairy cows has decreased while beef-production with suckler-cows has increased in Sweden.

The effect of additional nitrate and sulfur in the diet on the methane production in cattle

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.
