Global warming is generally recognized as one of the major environmental challenges we have to face in the near future. The students in school today are the ones that will have to deal with the consequences of it tomorrow. That is why education about it is so important. Previous research shows that students believe that environmental issues in general are important problems to be solved. I this study I tested students in grade twelve, in four different schools in order to find out what their level of knowledge about global warming is, how worried they are about it and if there are any correlation between their knowledge and their level of worry.

Food is widely consumed and in 2011 an average American devoured approximately one ton of food. The production of these goods requires large amounts of energy and contributes to 22-31 % of all greenhouse gas emissions occurring in Europe. More than one third of the produced food is discarded instead of consumed, and food waste make up about 30 % of the waste generated by households. 60 % of this food waste could be avoided if the eatables were handled in a better way.Avoidable food waste arises partly because residues from food are not taken care of, and because the food is not stored in a way that optimise its durability. Residues arises part- ly because of the contradictory and complex demands of everyday life and are, because of our busy lifestyle, difficult to avoid.

During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.

Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties. Biological control can be described as the suppression of damaging activities inflicted of a harmful organism by one or more other organisms, which are called antagonists or natural enemies. In Sweden, there are currently no registered biological control products available to control cucumber powdery mildew. The aim of this study was to investigate the effect of two biological control products in order to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level in greenhouse produced cucumber. In the experiments, different application regimes were also studied.

Global warming is going to affect our society in many ways. One can say that the problem we face has two different sides. One of those sides has received a lot of attention, namely how we can reduce our emissions of greenhouse gases. However, because of the climate system's inertia the climate will continue to evolve over a period, no matter how much we will cut back on emissions. Because of this, we have to start adapting our society to the climate changes that we cannot influence.

The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication. As more and more companies establish environmental strategies there exist beliefs that the environmental focus is becoming a triviality, which is the reason for this study. Implementation of words such as ?environmentally friendly?, ?green? and ?global warming? is becoming more and more widespread and frequently used within marketing communication.

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

To be able to hinder the global warming the emissions of greenhouse gases, carbon dioxide foremost, must decrease. By switching to green electricity, it is possible to reduce the emissions from electricity producing sources.In 1999, Swedenergy conducted a study about whether or not Swedish households would consider buying green electricity. According to the study, about 75 percent were willing to buy green electricity. 40 percent of these were prepared to pay a premium for green electricity. However, according to the results from the study, only one percent actually bought green electricity, and since 1999, this proportion has merely increased slightly.

Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable. The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

Abstract The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these. The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.

The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector. This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.
