The general goal of LCA for biogas energy systems is to determine the environmental impacts of producing and utilizing biogas as an energy source, i.e., energy and material requirements as well as emissions to the (biotic and abiotic) environment. Different biogas LCA studies have one or more of the following specific goals:

Introduction. The environmental benefits of biogas technology are often highlighted, as a valid and sustainable alternative to fossil fuels. [1] Together with the reduction of greenhouse gas (GHG) emissions, biogas can enhance energy security, thanks to its high energetic potential.

Introduction Singapore has one of the highest populated countries The objective of this MSc thesis is to examine the life cycle assessment (LCA) impacts of bio-gas/biofuel production within a system that may treat different types of organic waste substrates. The purpose is to understand how life cycle environmental impacts of biogas/biofuel production is influ- These observations show that contextualized environmental and economic evaluation for usual energy resources is crucial to disclose the advisability of biogas sources. Furthermore, this LCA highlights the importance of implementing an improved wastewater treatment with enhanced capacity to avoid eutrophication and global warming impacts coupled to one energy strategy based on BWWF valorization. On the one hand, the environmental sustainability of biogas has been widely analyzed in literature using Life Cycle Assessment (LCA).

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.

Biogas technologies are gaining prominence in the federal state of Lower Saxony (Germany). 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.
