An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer
Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.
Water balance and nitrate leaching from arable land in a changed climate : a model study
This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.
Effektivare energianvändning på Totebo AB
The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.
Svenska kärnvapenprogrammet under Kalla kriget : En studie av den internationella arena som påverkade uppstartandet och nedläggandet av Sveriges kärnvapenprogram
The purpose of this paper is to investigate possible reasons Sweden might have had to motivate the start and end of its nuclear program during the Cold war. This investigation will be conducted using a qualitative research method and making a comparison between the theories realism and liberalism?s ability to explain the decisions. The question this paper is based upon is as follows: Can Sweden?s creating and shutting down of a nuclear weapons program during the Cold war be explained by the international events and actions that were taking place during this time period? The result consists of liberalism pointing out several failures on the international level that might explain the cynical decision from Sweden to create the nuclear weapons. Realism considers the decision to make perfect sense at this point in time, to protect Sweden on the anarchy that was going on at that time according to this theory.The ending of the nuclear weapons program is being explained largely by the rise of the MAD-concept which renders the acute need of nuclear weapons in Sweden void. Liberalism on the other hand considers this a logic step due to the better established UN that is playing a larger role now than in the 1940s. In conclusion, realism does a better job explaining the start of the nuclear weapons program, while liberalism explains the end of it more efficiently. The contribution this thesis has to the research of political science can be seen mainly in three areas.
Klimatfrågan -från en kritisk händelse till en politisk modefråga?
Few issues have been exposed in media recently as much as the climate change issue. Afterthe documentary film ?An Inconvenient Thruth? presented by Al Gore was released in 2006,most of the world saw a lot of attention directed towards global warming. This was a turningpoint that is refered to in this dissertation an history-graded critical event, which is assumed tohave a significant impact on peoples lives.The purpose of this dissertation is to examine whether or not political parties in Swedenresponded to this critical event in the way that they, in their party programmes, haveformulated policies related to climate change. Alternatively if media produces an image ofpolitical activity which does not comport with the forming of actual political standpoints.
Miljövärdering av resurssnål betong med införande i BIM
This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

The aim of this thesis is to assess landslide susceptibility in Huddinge Municipality in middle Sweden. The main purpose is to produce a map, to visualize landslide susceptible areas, and to integrate the result with changes in physical factors such as climate change. Also, the thesis aims to analyze anthropogenic factors such as changes in land use and an increasing population in Huddinge Municipality. Methods used are GIS-analyses, interviews with staff of Huddinge Municipality, and field observations.
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..
Klimatfaktorers inverkan på granbarkborrens svärmningsintensitet i Medelpad
The spruce bark beetle (Ips typographhus) is one of the 25 000 species of insects in Sweden, an insect of great economic importance because it can alone terminate forest of high value. During the past decade, insights of climate change received with increasing attention. If the future brings a milder climate in the north and therefore a longer growing season, one would think that it would only affect the forestry to the better? Yet in recent time, outbreaks after storm felling seems to occur more frequently. The Spruce bark beetle ruins millions of cubic meter of Norway spruce (Picea abies) in Sweden alone, with more frequent storm felling and a larger amount of wind thrown threes in the forests there will also be room for an advancing reproduction.
Klimatpåverkan vid vägbyggnad -beroende av vald konstruktion
It?s a fact that the climate is affected by the vehicle that runs on the worlds roads. But theconstruction of the road itself is rarely thought of as a climate threat. Svevia and the Swedish roadadministration have opposite views of how the construction of roads should be carried thru. It?sthe difference between those two construction methods that is the base in our thesis.The amount of energy use or the emissions are not analyzed for neither the Swedish roadadministrations nor Svevias construction models.
Kallbad som turistattraktion : En studie om destinationsutveckling av Stockholms stad
Stockholm is considered as a tourist destination which has a lot of offers to attract tourists and if it utilizes it water better it can give a wonderful and unique experiences and cold baths may become an image to it.The aim of this study is to shed light on the open-air swimming-baths and shores of Stockholm. Also how to use this advantage as it?s a city based on many islands, the purest water in Europe and this makes Stockholm as a destination a very attractive place for tourism. For a better understanding of our study, we have studied the quality and quantity to see how people began to exploit open-air swimming-baths throughout history everywhere in Europe and specifically of Stockholm city sea shore. We did a study on the history traditions of open-air swimming-baths and how it can be a tourist attraction through books and interviews, scientific articles and our personal observation, so that we can analyze how to develop sustainable tourism in the future and how Stockholm city can make development of opportunities for the future.
Comparison of stable environment in prior approved and non-prior approved horse stables
To establish good horse welfare there are several factors that need to be considered. One important factor is the environment in which the horses are kept. In Sweden horses are stabled during long periods of time in the cold season and consequently the stable environment is even more important. The most essential environmental factors in a horse stable are ambient temperature, relative humidity (RH) and concentrations of contaminants in the stable air. The air in a horse stable contains dust, noxious gases, moulds and microorganisms which all can contribute to developing respiratory diseases in horses.
Sambanden mellan inandningsbara, grova och fina partiklar i luften och strokeanfall i Malmö
In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old who live in Malmö. Levels of particulate matter were measured from October 2004 to April 2005 at a central outdoor monitoring site in Malmö.
Klimatinducerade fenologiförändringar och dess effekter i näringsväven
The climate affects animal populations through several processes. These processes includereproduction, phenology and the success of hunting. By influencing the phenology of species theclimate also affects the way species interact. If a climate-induced phenology change promotes abasal species to bud earlier in the spring for example, this will affect the links to other species inthe food web due to a time lag in the tropic levels above. This dependence, that a predator has tobeing synchronous to its prey, is called the match/mismatch hypothesis (MMH).
