Detailed breakdown of the results for climate change are presented in Figure 3. End products for the
various scenarios are presented in shades of blue, while inputs into the biogas production, including
logistics are presented in green. System expansion products are coloured in shades of brown.
In terms of direct emissions of the end products, there is a climate benefit to the combustion of biogas
in the buses when compared to the incineration of the raw organic waste. In Case 0 and Case 1, the
secondmost significant impact comes from the diesel bus fuel included as a system expansion product.
For the biogas scenarios (cases 2-4), the most significant contributors to climate change impact are the
direct emissions from biogas combustion, emissions related to biogas production and the emissions from
the system expansion products for district heating
