This chapter delves into the holistic assessment of the environmental impacts associated with the entire biogas system processes, from the provision of the feedstock to the various biogas technologies and the different end-use applications of biogas. Therefore, the methodological framework of life cycle assessment (LCA) is presented to quantify greenhouse gas emissions, energy consumption, and other environmental metrics. In addition, the most important aspects for carrying out a LCA of biogas processes are highlighted, and an overview of the current legal framework and its impact on assessment methodologies is given. Examples are used to show both the most sustainable production and utilization pathways for biogas in the future and introduce methodological and technical requirements for the further development of biogas systems. Finally, an outlook is given on possible developments of biogas technologies toward an overarching technology to reduce greenhouse gas emissions from organic waste streams, implement a circular economy, and link with a sustainable bioeconomy.

Abstract
This chapter delves into the holistic assessment of the environmental impacts associated with the entire biogas system processes, from the provision of the feedstock to the various biogas technologies and the different end-use applications of biogas. Therefore, the methodological framework of life cycle assessment (LCA) is presented to quantify greenhouse gas emissions, energy consumption, and other environmental metrics. In addition, the most important aspects for carrying out a LCA of biogas processes are highlighted, and an overview of the current legal framework and its impact on assessment methodologies is given. Examples are used to show both the most sustainable production and utilization pathways for biogas in the future and introduce methodological and technical requirements for the further development of biogas systems. Finally, an outlook is given on possible developments of biogas technologies toward an overarching technology to reduce greenhouse gas emissions from organic waste streams, implement a circular economy, and link with a sustainable bioeconomy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
