Abstract (englisch):

One of the main drivers for switching the current energy system from a conventional fossil-base to one dominated by renewable technologies is climate change. However, energy system transformation aiming at reducing greenhouse gas (GHG) emissions may lead to increases in other types of environmental impacts. Incorporating environmental impacts beyond climate change into future energy systems is required, in order to develop energy policies that do not, or at least can reduce, conflict with other goals.
With this as the background, this thesis couples life cycle assessment (LCA) with energy system analysis, to broaden the scope by including additional environmental impacts, and to switch from a direct emissions perspective to a life cycle perspective. For this purpose, a standard LCA approach is applied to assess energy technologies. Subsequently, the standard LCA is extended to couple with energy system models (ESM) for the assessment of multi-technological energy systems, from both life cycle and energy system perspectives. Considering the methodological challenges that occur due to differences between the models resulting from their different system boundaries, databases, and the levels of detail of their input data, the thesis introduces the Environmental Assessment Framework for Energy System Analysis (EAFESA) as a guideline for studies to cope with model coupling between LCA and ESM.
