Default value “PME (process with methane capture at oil mill)”:
Assumes biogas plant at oil mill and thus zero net emissions at oil mill
Default value “PME (process not specified)”: Worst case is assumed, i.e. open ponds with standing water conditions lead to anaerobic
digestions and thus high CH4 emissions

Between the default values, many more attractive options to reduce GHG emissions exist. The problem is that GHG emission values are not available
