CSR, ett spel för gallerierna? : en studie om varför ett antal Svenska företag väljer att arbeta med CSR

Social inequality, economic imbalances and greenhouse gas emissions are some of the greatest risks threatening society today. Society has become more aware of these risks and has started to demand firms to take more responsibility. During the last 30 years firms and mainly large firms has chosen to work with something called CSR. CSR stands for Corporate Social Responsibility which is the work firms engage with to take responsibility for environment and society as a whole. Scientists and business people has taken two sides towards CSR, one side argues that CSR cost more than it tastes and the other side argues that firms which engage with CSR will gain economic benefits.

Ett nytt växtsortiment - för inglasade miljöer :

A new project has developed at the Swedish University of Agricultural Sciences in Alnarp during the spring of 2006. The garden design students has, during the course Interior Garden Design designed and built an construction with a new range of plants for Swedish conservatories. The plants are mainly from the cool temperate areas, instead of the tropical which often are the most common in public spaces. This means, among other things, that the cost for warming is very low. The working process and the construction carried on as workshops in the conservatory at Trädgårdslaboratoriet in Alnarp. During a few weeks the hole construction is completed.

Går det att lära gamla hundar att sitta? : En studie om att ändra på en verksamhets utskriftsvanor.

The consumer society exploits the earth?s resources more than the earth itself has capability to produce. This over-consumption causes a mass production of products, which mean that more greenhouse gases are being emitted to the atmosphere. This is one of the reasons why the earth?s temperature is rising, where the result of it is worldwide disasters.

Flexibilitet från försörjningskedjan : En fallstudie på ett globalt tillverkningsföretag

Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.

Optisk sortering av matavfall : en jämförelse med en minskning av svinnet

The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.

Ekonomiska innovationer i den gotländska vindkraftsindustrin

Currently there is a controversial debate about that we must reduce our impact on the global warming; therefore both the Government and the local authorities have invested heavily in developing renewable energy in Sweden. The major development on the wind power market can be seen as a result of both the technological development and also on the decision that the Government took in 1996, which opened up the wind power market for private parties.This paper has aimed to examine the types of financial innovations that have arisen from the investments and financing of wind power on Gotland, and what these innovations can contribute to the future development of wind power.The problems that this thesis is based on is; what kind of financial innovations have occurred within investment and financing of wind power? How can these innovations contribute to the continued development of wind power on Gotland? The conclusion of this study shows that respondents and participants have defined a number of financial innovations that have emerged. Where some of the innovations only can be seen as incremental since they are based on continuous improvements, while others can be seen as radical as they are completely new for the context in which they operate. The study has also shown that Gotland has a great potential to produce more renewable electricity, but the development is dependent on the new power lines being built, in order to export electricity to the mainland..

Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

Undervisning om miljöproblem i Cradock - Sydafrika

The purpose of this paper is to investigate some aspects of teaching environmental issues, as they are manifested in another culture. In this paper, I will discuss how you teach environmental issues, how the teaching environment is formed, and what an environmental issue means to a South African teacher, as well as, if there are any cultural aspects to what an environmental issue is. Seven observations were made and qualitative interviews with four teachers teaching Life Science in Cradock, South Africa - The results showed that these South African teachers, independent from each other, followed a similar pattern in their teachings. These patterns contain gathering information concerning environmental issues in the immediate surroundings, as well as using the text book and teaching environmental issues through lectures. It was not possible to draw a conclusion about the cultural aspects in association to environmental issues.

Anestesisjuksköterskans metoder att förhindra hypotermi

Hypotermi, en sänkning av kroppens kärntemperatur under 36°C, är en oönskad men vanlig komplikation under den perioperativa perioden. Det är förenat med en rad negativa konsekvenser som kan orsaka lidande för patienter och innebära ökade vårdkostnader. Svårigheterna med att på ett enkelt och effektivt sätt förhindra hypotermi utgör ett hinder i vården och nya produkter utvecklas därför kontinuerligt. En viktig del i anestesisjuksköterskans arbete är att bevara patientens kroppstemperatur så nära det normala som möjligt. Syftet med föreliggande litteraturstudie var att beskriva olika metoder som är lämpliga för anestesisjuksköterskan att använda för att förhindra hypotermi hos vuxna i det perioperativa förloppet.

Biogas : En systemanalys av Solna Stads matavfallsprocess

Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.

I Sverige pa?gick under 2013 efterbehandlingsa?tga?rder pa? 1789 fo?rorenade omra?den. Det nationella miljo?ma?let ?giftfri miljo?? har av regeringen angetts som det styrande miljo?- ma?let vid efterbehandling. Efterbehandlingen syftar till att minska risken fo?r fo?rore- ningsspridning i mark fra?n avslutade verksamheter som industrier, va?gar med mera.

Den klimatsmarta grisen - visst finss den! : En LCA av gris och olika förändringar i produktionssystemet i syfte att minska klimatpåverkan.

Förståelse för hur vår mat påverkar klimatet blir allt mer viktigt. Grisproduktion har visat sig ha betydligt mindre klimatpåverkan än nötköttsproduktion dock har befintlig forskning visat att all köttproduktion relativt sett leder till stor miljöpåverkan. Att grisen står sig starkt i miljösynpunkt jämfört med nötkött ger inget skäl till att inte försöka göra grisen mer klimatsmart. Syftet med studien är att beräkna potentialen att minska den svenska grisens klimatpåverkan genom olika produktionsförändringar. De produktionsförändringar som undersökts är; användning av förnyelsebar energi till stall(vindkraft), biogasproduktion av gödsel och användning av restprodukter som foder och då matavfall. Detta är en screening-livscykelanalys där endast Global Warming Potential tas i hänsyn med ett 100 års perspektiv. Den funktionella enheten(FE) är 1 kg ben- och fettfritt griskött. Genom att använda förnyelsebar energi i form av vindkraftproducerad el till stall kan klimatpåverkan potentiellt minskas med 3,3 %.

Energikonsumtion hos en diskmaskin

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

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.
