of renewable and non-renewable material resources, renewable and non-renewable primary
energy and water.
Use of renewable primary energy excluding renewable primary
energy resources used as raw materials
Use of renewable primary energy resources used as raw materials
Total use of renewable primary energy resources (primary energy
and primary energy resources used as raw materials)
Use of non renewable primary energy excluding non renewable
primary energy resources used as raw materials
Use of non renewable primary energy resources used as raw
materials
Total use of non renewable primary energy resources (primary
energy and primary energy resources used as raw materials)

Life cycle inventory analysis and life cycle impact assessment
7.2
Indicators for the life cycle impact assessment according to EN 15978
“Baseline Scenario”
The following information on environmental impacts is expressed with the impact category
parameters of LCIA using characterisation factors
Global warming potential (GWP);
kg CO2-equiv.
Depletion potential of the stratospheric ozone layer (ODP);
kg CFC 11- equiv
Acidification potential of soil and water, (AP);
kg SO2 - equiv
Eutrophication potential (EP);
kg (PO4)3- - equiv
Formation potential of tropospheric ozone (POCP);
kg Ethene - equiv
Abiotic depletion potential (ADP-elements) for non-fossil resources
kg Sb - equiv
Abiotic depletion potential (ADP-fossil fuels) for fossil resources
MJ, net calorific value
In fact, the results from the impact assessment are only relative statements which give no
information about the endpoint of the impact categories, overstepping of threshold values,
safety margins or risk.
7.3 Other indicators for the life cycle impact assessment
Please give here the reference of the LCIA method used and a statement telling why it was
relevant to include additional indicators from EN 15978 “Baseline Scenario”
