• The characterization model is adaptable to spatial <strong>and</strong><br />
temporal explicit evaluation<br />
• Global geographical validity preferable, separate validity<br />
<strong>for</strong> Europe beneficial<br />
• The method is compatible with, or developed specifically<br />
<strong>for</strong>, the comparative assessment scope of LCA (e.g.<br />
factors do not include security factors / precautionary<br />
principle)<br />
When empirical data is used, double counting is avoided<br />
• All critical parts of the environmental mechanism<br />
describing the cause-effect chain are included with<br />
acceptable quality.<br />
A specific underlying model is used<br />
L<strong>and</strong> trans<strong>for</strong>mation is considered<br />
L<strong>and</strong> occupation is considered<br />
Duration of physical changes is considered<br />
Physical changes to fauna <strong>and</strong> flora are considered, e.g.<br />
altered species composition, reduction of habitat size<br />
elsewhere<br />
Physical changes to soil are considered, e.g. altered soil<br />
function, changes in water conditions or soil erosion<br />
Physical changes to soil surface what creates unique<br />
l<strong>and</strong>scapes are considered<br />
Effects on climate change are considered, due to albedo<br />
change or changes in CO2, NO2 or CH4 releases.<br />
Effects on changes in Net Primary Production are<br />
considered, due to altered soil function or species<br />
composition.<br />
Biodiversity loss due to altered species composition is<br />
considered<br />
Biodiversity loss due to reduction of habitat size elsewhere<br />
is considered<br />
• The critical part of the model including the input data<br />
have been peer reviewed (journal, panel, book, etc.)<br />
• The model reflects the latest stage of knowledge <strong>for</strong> the<br />
cause-effect chain (the critical links are covered)<br />
• All category indicators <strong>and</strong> characterisation <strong>models</strong><br />
linking midpoint to damage fulfil the <strong>requirements</strong> of<br />
science based<br />
• The coverage of the impacts in the modelling from<br />
midpoint to endpoint is complete<br />
• The model including the underlying data have a good<br />
potential <strong>for</strong> being consistently improved <strong>and</strong> further<br />
developed including regarding geographical/emission<br />
situation <strong>and</strong> temporal differentiation<br />
• Indicators can be confirmed <strong>and</strong> verified against<br />
monitoring data, if available<br />
• Uncertainty estimates of the indicators are provided,<br />
justified <strong>and</strong> reported in statistical terms<br />
• Scenario <strong>and</strong> model uncertainty are taken into account<br />
• The category indicator <strong>and</strong> characterisation <strong>models</strong> are<br />
science based<br />
