Model uncertainties
Models are by definition affected by uncertainties (in input data, input parameters, scenario definitions, etc.). Have the model uncertainties been quantified? Are uncertainties accounted for in your simulations?
- response
- yes
- details
- The following input parameters are affected by uncertainty: sales volumes, packaging unitary masses. Model uncertainties have been partially quantified through a deterministic interval uncertainty analysis. Specifically, the uncertainty in packaging unitary mass values was evaluated using its estimated minimum and maximum plausible bounds. The model outputs were computed across this range to determine the upper and lower bounds of the results.

Sensitivity analysis
Sensitivity analysis helps identifying the uncertain inputs mostly responsible for the uncertainty in the model responses. Has the model undergone sensitivity analysis?
- response
- no
- details
- No formal sensitivity analysis has been performed to date.

Have model results been published in peer-reviewed articles?
- response
- no
- details
- url
Has the model formally undergone scientific review by a panel of international experts?
Please note that this does not refer to the cases when model results were validated by stakeholders.

Model validation
Has model validation been done? Have model predictions been confronted with observed data (ex-post)?
- response
- yes
- details
- The model was validated by comparing the total quantities of plastic packaging with a top-down estimate provided by an MFA model at EU level

Transparency
To what extent do input data come from publicly available sources?
This may include sources accessible upon subscription and/or payment
- response
- Entirely based on publicly available sources
Is the full model database as such available to external users?
Whether or not it implies a specific procedure or a fee
- response
- no
- details
- Raw data on sales volumes cannot be disclosed, while the unitary masses of packaging types are listed in Annex 1 of the technical report.
