hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?
… 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 …
en studie av effekter på växthusgasutsläpp och kostnader
… two major environmental benefits from producing biogas; reduced carbon dioxide emissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions from returning digestate from the bio reactor to farmland instead of using industrial fertelizer. In order …
… implement information technology in their business in order to reduce their emissions. This thesis has three aimes: to calculate a small company´s carbondioxide emissions, study whether or not information technology could help to reduce these emissions and furthermore find out …
… issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but …
The Ethics of Emissions Trading
International regulations target a global reduction of carbon dioxide (CO2) emissions through the allocation of national reduction targets and the definition of mechanisms to achieve these targets. One of these mechanisms is international emissions trading, these trading …
In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest …
En kritisk metodgranskning baserad på kvantitativa data
… area that is appropriated to accumulate all carbon from total carbon dioxide emissions in Stockholm and Norrbotten County respectively. The appropriated ecosystem area represents the ecological footprint. The ecological footprint is also calculated for Stockholms läns …
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At …
… and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section …
myllning och surgörning som metoder för att minska avgång vid spridning
The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer …
växthusgaser, energi- och resursanvändning i modellstudie
… was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on …
When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of …
The quantity of methane emissions from sheep depend on several factors, for example, the composition of the diet, feed quality, the age of the animals, time of the day and maybe also breed and sex. A comprising literature review was made about which factors that affect the size …
en analys av medlemmarnas motiv till beslut
Under 2009 lanserade Lantmännen handel med emissionsinsatser och emitterade förlagsandelar. Handeln med emissionsinsatser syftar till att behålla emissionsinsatserna i Lantmännen, då många av medlemmarna är äldre och kommer att begära utträde ur föreningen kommande år. Handel …
… were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials. For food production the biogenic greenhousegas emissions are also important, such as the emissions of carbon dioxide and nitrous …
