Life Cycle Assessment of Household Consumption
Doctoral thesis of Andi Frömelt and doctoral thesis of Dominik Saner
The goal of this project is to model and assess current and future household consumption considering environmental performance and technical feasibility. Status quo and prospective life cycle assessments (LCA) of household consumption shall identify strategies to decrease the overall environmental impacts of production, transport, and disposal of goods and services in the areas of mobility, housing and nutrition. Thereby, a special focus is laid on mobility behavior, increasing use of shallow geothermal heat for housing, and direct and indirect energy and resource use for food. The analysis will compare local supply systems (i.e. particularly dispersed electricity and heat generation, etc.) with centralized energy supply systems in the context of the 1 ton CO2 per capita society and the goal of many municipalities to obtain a high degree autarky in terms of energy generation. These societal and environmental goals will lead to methodological issues about the coupling of scenarios with LCA, the choice of the correct functional unit and spatio-temporal systems boundaries and resolution for the assessment of household consumption and the selection of most appropriate set of indicators covering global (e.g. global warming) and regional environmental impacts (e.g. particulate matter formation).
