… increasing throughout the world. The energy used in these data centers and the emissions from the use are increasing at the same rate. The total use of energy will double from 2008 to 2011 based on the trends in data centers use. Research in this area says that the emissions …
relations between enteric production and production from faeces and urine
… which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching …
från modell till verklighet
In the near future we need to reduce the greenhouse gas emissions significantly for the benefit of the environment around us. The European Union has de-manded a variety of climate and energy goals to be achieved by year 2020, the ”20-20-20” targets. With these aims, The European …
En fallstudie av Hägern 11 och EU Green Building
… och fastighetssektorn står idag för 40% av världens energianvändning. De CO2-emissioner som förbränning av fossila bränslen genererar påverkar jordens växthuseffekt. EU-direktiv rörande en effektivisering och minskning av energianvändningen har implementerats för att minska …
… deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it …
En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys
… and economic point of view. The life-cycle analysis covers only carbon dioxide emissions, since it is the most spoken of in today’s climate agenda. Furthermore, this study aims to highlight which parts, of the system boundary, that contributes to greater carbon emissions for the …
… of climate change and has a common target for reductions of greenhouse gas emissions. In spite of this, there are great differences between the member states capacity and dedication to the cause of implementing the Unions climate policy and reduce their emissions. The purpose of …
En litteraturstudie och rötning i labbskala
… benefits of digesting pea residue include reducing nitrous oxide emissions of 500-1200g per hectare. Other environmental benefits include the reduction of ammonia emissions and nitrate leaching. Biogas as a fuel is neutral as regards carbon dioxide emissions and can replace …
… gas. But how large is the WWTP´s share of nitrous oxide to the total emissions? To answer this question an increasing number of WWTP´s around the world have begun to study the emission of nitrous oxide. Today it is still not entirely clear where in the process nitrous oxide …

The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted …
… demand would decrease which ultimately leads to lower carbon dioxide emissions. Dependent on which investment is chosen the total carbon dioxide emissions are reduced by between 0,33 to 0,52 metric tons per year. This value does not however take into account the systems total …
Klarläggande av framtida hållbarhet
Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen …
klimatpåverkan från samhällsplaneringsprojekt
… the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to …
… and analyzed through three case studies, two case studies of particulate emissions in Beijing and a case study of sulfur dioxide emissions in Shanghai. In the current situation, these two agents do not have sufficiently strong incentives to reduce their emissions, partly because …
En sammanställning av kostnader och klimatpåverkan vid tjänsteresor samt analys av sociala effekter vid ett skifte mot videkonferens i en organisation
… of transport and with a change against virtual meetings affects greenhouse gas emissions and costs. An additional purpose is to gather information about currently known differences between natural and virtual meetings and explain these with a focus on interaction and …
