Temporal Differentiation
When looking at a product's life cycle, emissions and resource use as well as the resulting impacts usually occur at different points in time. For instance, construction materials are often 'stored' in buildings for many decades before they are recycled or disposed of. In order to capture such system dynamics, we use scenario analysis in combination with substance flow analysis and temporally differentiated fate models to quantify possible future emission flows. Temporally differentiated analyses raise the question whether the same weight should be assigned to current and future emissions. In this context, we discuss the transferability of economical concepts such as discounting to environmental problems.
