The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

This study will identify the environmental impact in terms of carbon dioxide for a boiler house on behalf of Kvänum energi. The boiler central consists of a main building, which in turn contains multiple components such as boilers, pipes, etc, the boiler central uses pellets fuel. It also includes a silo and an ash container. The total weight of the boiler is about 63 tons. Each boiler has an output of 600 kW; the central includes three boilers with room for a fourth if necessary.

This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.

Potato late blight is one of the most important potato diseases worldwide. The disease is caused by an oomycete called Phytophthora infestans. The host range of P. infestans includes potato (Solanum tuberosum) and hairy nightshade (Solanum physalifolium). Hairy nightshade has recently established itself as an important weed in the southernmost part of Sweden.

To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.

Africa is one of the regions most affected by climate change. However its forests are important carbon sinks for the whole world, and if recognised as a global public good, could be conserved and contribute to green house gas emission reductions. A global mechanism, Reduced Emissions from Deforestation and forest Degradation(REDD+) aims to help developing countries in reducing emissions from deforestation and forest degradation, and enhancement of carbon stocks. REDD+ strategies may, however exclude local forest dependent communities from forests in order to conserve and maximise carbon stocks, thus having a severe impact on local livelihoods. Therefore, how local communities can participate and share benefits from REDD+ is a key concern.This study investigates how three forest dependent communities in the Nazinon forest, in Southwest Burkina Faso could financially benefit from a REDD+ project.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997. The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

AbstractBachelor thesis in political science by Alexander Hassan, autumn 2008, ?Effects of external factors on a nations democratisation process during the transition from authoritarian to electoral democratic rule ? A categorical analysis?Supervisor: Tomas SedeliusIn recent years globalization has become a hot topic in understanding the world we live in today. Globalization has indeed had a great impact on international relations and with it a great influence on the domestic conditions that determine a nation?s possibilities. It is therefore rational to hold true that this also would apply to a nation?s democratic process.

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

During the later half of the 20th century standard form contracts began to be used more frequently in contract situations. This trend has been consistent and in today?s world numerous commercial parties employ such contracts in their business transactions. The reasons for the extended use of standard form contracts are the benefits that can be obtained for the parties such as time efficiency, effectiveness and price advantages. Standardised contracts often regulate certain issues of the contract for example the way of delivery, remedies and complaints.

This is a 15 hp (10 p) thesis in biology at the programme for Horticulture Management at the Swedish University of Agricultural Sciences, Alnarp. In this literature study we have processed, reviewed and arranged facts and research, to make it more available for those who want to know more about establishment or cultivation of mosses. Our client is Fredriksdal?s Museums and Gardens in Helsingborg who are planning to establish a moss garden. The information is meant to be used by Fredriksdal and other similar facilities.

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).
