Life cycle analysis (LCA) is a tool used to account for inputs and outputs to complex systems. In essence, it is a budgeting process that accounts for all inputs (raw materials and energy) and outputs (products, waste materials, and environmental impacting components such as CO 2 ).

The number of biogas plants has nearly tripled within the last seven years, from 435 plants in 2004 to 1,300 in 2011. Economic incentives for this development are provided under the Renewable Energy Law (German: EEG). eller övergödningspotentialen för produktsystemet i någon större utsträckning om biogas används istället för naturgas.

This study aims to make further contributions to the discussion on the environmental sustainability of biogas. The paper considers life cycle environmental impacts of electricity generation in five real AD-CHP systems using biogas produced from differing mixes of four types of feedstock. Biogas produced by AD is considered to have a high saving potential with respect to greenhouse gas (GHG) emissions (EC, 2009).

Ifølge reglerne skal data indsamles fra hver enkelt E-LCA has been applied in this particular paper to investigate the environmental footprints of using biogas as a transport fuel in Sweden (the most common application in this country), for co-generation of heat and electricity in Brazil and as a cooking fuel in households in China.

Moreover, some LCA studies have also been performed on hydrogen production from biogas. Hajjaji et al.

Det finns endast ett fåtal livscykelanalyser för framställning och användning av biogas som drivmedel i Sverige. Vid At present, biogas in Switzerland is mainly produced from sewage sludge, slurry, and biowaste. If the co-digestion with higher shares of substrates made from energy crops increases significantly in future, the produced biogas cannot comply with the thresholds for a fuel tax reduction anymore. On the one hand, the environmental sustainability of biogas has been widely analyzed in literature using Life Cycle Assessment (LCA). Berglund and Börjesson described the energy balance of biogas production in a life cycle perspective, highlighting that the net energy output turns negative when transport of raw materials exceeds distance limits [ 14 ]. [12] reviewed the LCA study of biogas production in Europe, and also found sources of feedstocks for biogas determining the overall environmental impact for biogas systems.

In order to improve the yield of biogas plants, operators often purchase or cultivate substrates with high energy content.

Different biogas LCA studies have one or more of the following specific goals: LCA of Biogas production from purchased substrates In order to improve the yield of biogas plants, operators often purchase or cultivate substrates with high energy content. The environmental impacts due to the digestions of these substrates can be analysed with a life cycle assessment (LCA).

Tankstationer för fordonsgas finns över stora delar av landet. Det finns idag drygt 200 publika tankstationer och ytterligare ca 60 ickepublika tankstationer för bland annat bussar. LCA kan användas som en del av olika styrsystem inom miljöområdet, t.ex.
