An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

The swedish national environmental goals have different policies and developments connected to them in order to achieve the goals on time, but the implementation of the different policies differ and is hard to evaluate compared to the theoretical background. With this thesis I have chosen to investigate the climate investment programmes results in Östersund compared to its goals with a case study. The different projects within the climate investment programme have reduced the emissions of CO2, but not in the amount that was anticipated and a lot of the projects were within projects that the municipality already was developing or doing. .

This report analyzes disposable packaging and returnable packaging with the methods life cycle analysis and life cycle costs analysis. These two different packaging are analyzed through the company Clas Ohlson?s packaging-flow. To get a picture of how the flow works, a visit at the company and email contact have been done with Clas Ohlson to get relevant informationToday Clas Ohlson has a big flow of articles to the stores without larger variations in the demand, with the exception of autumn, which is when customers start shopping for Christmas. Clas Ohlson?s articles are placed on a pallet and are wrapped into plastic-film for protection and to make sure that nothing will be stolen.

I detta arbete undersöks attityder, motivation och tankar kring miljövänligt beteende på arbetsplatsen bland anställda inom skola och omsorg i tre Dalslandskommuner. Två av dessa har infört en arbetsprocess som låter de anställda, tillsammans i arbetslaget, sätta sina egna mål för miljövänliga arbetsrutiner på arbetsplatsen. Inspiration till studien kommer från Self-Determination Theory (Ryan & Deci 2000) och Value-belief-norm Theory (Stern 2000). Data samlades in och analyserades med både kvalitativa och kvantitativa metoder. Kvantitativa data från 169 frågeformulär som behandlade motivation och attityder användes främst som bakgrundsdata till fem stycken intervjuer.

The real estate company Ihus is facing an expansion of its comfort cooling in Noatun,Uppsala, to provide the buildings in the block with cooling. The buildings in Noatunare mainly used for office premises, where the requirements for an accepted indoorclimate is great. However, it?s uncertain whether Ihus should continue, as currently,producing comfort cooling by themselves using a compressor chiller, or if they shouldconnect themselves to Vattenfall?s district cooling net.The purpose of this report is to examine which technique of cooling is best suited forIhus and their buildings in Noatun. It should also work as a guideline for othercompanies facing the same problem as Ihus.

How the renovation of the vast Swedish existing building stock with renovation needs will be performed is considered as decisive in order to achieve the target set by the Swedish government of reducing the energy use by 20 percent by 2020. Consequently, the challenge of the building sector consists in reducing the energy use in the existing building stock but at the same time ensuring that the indoor environmental quality is improved and the cultural values are maintained.So far, there have been a few renovation projects which strongly have reduced the energy use and at the same time have taken into account the environmental aspects and the cultural values. The main reasons are that there have been few incentives and a lack of routines in order to steer efficiently a ?sustainable renovation?.The participants in a Nordic project on sustainable renovation thought that it would be a strong advantage to link the concept of sustainable renovation to the Miljöbyggnad certification system. Indeed it is trusted by the Swedish building and construction sectors and can provide sustainability targets in order to steer renovation processes.The objective of the master thesis is to show how the Miljöbyggnad certification system could be integrated in practice in the renovation process of Riksbyggen, an organization which administers housing associations (Bostadsrättsföreningar) and build houses.

A group of two people, Jelena Durkan and Johan von Heideken, have worked together on an assignment from the company August Lundh AB. The company manufactures plastic products for all sizes of catering establishments. The basis for this thesis is a pre-study which shows that many of the users would be more drawn to the plates that the company manufactures, if there was a motif on the plates.This thesis will present the method of application for the motif that best benefits the company, with regard to the requirements placed on the motif, application method and the costs. The group found five relevant methods that were more carefully examined and compared to each other. Those are:Laser engraving, Hot-stamping, Injection molding, In-mould labeling and Pad-printing.The tools that have been used to solve this problem are: Requirement specification, QFD and OEE.

As a result of the Civil Protection Act, there is an imperative for Systematic Fire Preventive Measures, SFPM. SFPM can be divided in two parts: organisational preventive measures, and documentation of fire preventive measures. The manner in which SFPM is to be conducted is similar to that of the environmental management system ISO 14001. This report provides suggestions how to integrate SFPM with ISO 14001..

Studien har sin utgångspunkt i en trend som blivit allt mer synlig under den senaste tiden; människor tar ett personligt ansvar för globala problem. Studiens syfte är därför att undersöka hur medvetna människor ser på frågan om personligt ansvar vad gäller globala problem? Studien är gjord som en fallstudie och undersökningsenheten, eller fallet, är deltagare på kursen Hållbar utveckling. Metoden är intervjuer. Jag har genomfört semistrukturerade intervjuer med fem kursdeltagare och dessa intervjuer utgör studiens empiriska underlag.

Travelling children is the topic of my work. Children who commute between more than one home. Society is rapidly changing and so is the concept â familyâ . The nuclear family is no longer the most common one. Children are now travelling more frequently than ever.

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

This thesis was conducted at Mälardalen University in Västerås and Härjeåns Nät AB, mainly in Sveg. Härjeåns Nät AB is a network company that delivers electricity in Härjedalen municipality, Ånge Municipality, Ragunda and Bräcke municipality. The maintenance and dismantling of electricity and broadband networks generates a lot of waste. The purpose of this work is to present proposals on the management of the waste. The goal is that all of Härjeåns offices should have equal management for the waste and an overview of how to manage the various wastes.

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Det är framförallt två övergripande frågor som vi har försökt besvara med denna studien: Hur är situationen vad gäller väg- och tågtrafikinducerade buller- och luftföroreningar i Burlövs Kommun 1994 och hur många av kommunens invånare påverkas av för höga halter/nivåer? Är den översiktliga metoden som vi har valt att arbeta med, i kombination med tillgänglig data, lämplig och tillräckligt exakt för att beskriva den aktuella miljösituationen i Burlövs Kommun?.
