ILCD Handbook: Framework and requirements for LCIA models and indicators First edition
The ecosystem damage model on primary production is scientifically robust.
The model including the underlying data have a good potential for being consistently
improved and further developed including geographical/emission situation and temporal
differentiation.
The table below presents the general and specific criteria for ozone depletion identifying
the minimum score (threshold value) to be met and the most relevant criteria for the impact
category (importance).

importance.

• Timeframe, discounting, etc.
• Marginal (M) or Average (A) defined, if not described

score)
• Total number of substances covered by the provided
characterisation factors
• The impact indicator covers the majority of impact
mechanisms and relevant elementary flows for the AoP
Human Health
• The impact indicator covers the majority of impact
mechanisms and relevant elementary flows for the AoP
Natural Environment
• The impact indicator covers the majority of impact
mechanisms and relevant elementary flows for the AoP

B H
• The midpoint indicator is chosen at the right point in the
cause-effect chain, where all LCI are aggregated as early
as possible in the cause effect chain
• The characterization model is adaptable to spatial explicit
evaluation
• The method is compatible with, or developed specifically
for, the comparative assessment scope of LCA (e.g.
factors do not include security factors/precautionary
principle) H
• When empirical data is used, double counting is avoided
•The model is representative for a generic global scale B H
• There is consistency between the different endpoint
indicators
Overall evaluation
• All critical parts of the environmental mechanism
describing the cause-effect chain are included with
acceptable quality C H
Overall evaluation
Scientific
robustness
• Atmospheric fate and transport is considered
• For damages on ecosystems, all relevant effects are
considered
• For damages on Human Health, all relevant effects are
considered
• The critical part of the model including the input data
have been peer reviewed (journal, panel, book, etc.) H
• The model reflects the latest stage of knowledge for the
cause-effect chain (the critical links are covered)
• All category indicators and characterisation models
linking midpoint to damage are science based
• The coverage of the impacts in the modelling from
midpoint to endpoint is complete
