Figure 2 compares the cases studied against the current day scenario (Case 0). There is little difference
between the five cases in the climate change impact category, but significant reductions are expected for
the biogas cases in the other impact categories. A trend within the three biogas cases is observed; the
construction of a new biogas facility in Trondheim presents the best environmental performance of the
three, followed by the biogas facility in Verdal, then Sundsvall. Specific impact assessment results are
presented in Table 2.
