Analysis of all data sources declared, checking their context-specific correct use as well as their relevance and quality.
enumeration
Sample tests on calculations
Values in the inventory are re-calculated from the raw data, or other calculations are validated exemplarily, e.g. scaling, averaging, summing up,stochiometric calculations, formulas in the mathematical models, etc.
enumeration
Energy balance
The energy balance (e.g. gross or net calorific value or exergy) of the Inputs and Outputs is validated. [Note: For processes that have undergoneallocation or consequential modeling the value of this review method is limited.]
enumeration
Element balance
The balance of the relevant chemical elements of the Inputs and Outputs is calculated and validated. The validated elements should be named in thereview comments. [Note: For processes that have undergone allocation or consequential modeling the value of this review method is limited.]
enumeration
Cross-check with other source
Comparison with other, independent data and/or information sources (can be both database and literature).
enumeration
Cross-check with other data set
Comparison with similar process or product system from the same or from other sources (can be both database and literature).
enumeration
Expert judgement
Analysis by means of expert opinions. The expert(s) have methodological and detailed technical expertise on the item to be verified and the processor product system in question.
enumeration
Mass balance
The mass balance of the Inputs and Outputs is validated. [Note: For processes that have undergone allocation or consequential modeling the value ofthis review method is limited.]
enumeration
Compliance with legal limits
Regulated Inputs and Outputs e.g. emission data are validated for compliance with legal limits, typically after relating and scaling the data tothe regulated processes/sites etc.
enumeration
Compliance with ISO 14040 to 14044
Methodological compliance with ISO 14040 to 14044 was checked by an LCA expert.
enumeration
Documentation
Evidence collection by means of documentation (e.g. data set's meta data, background report)
enumeration
Evidence collection by means of plant visits and/or interviews
Interviews and/or plant visits are performed to validate data and other informtion, tyically in case of inconsistencies, uncertainties, or doubts.People interviewed have detailed technical expertise on the analysed process(es).

Facets
enumeration
Raw data
Review/verification is done on basis of the original "raw data", i.e. the data before it was scaled, converted, or treated in other ways to be usedfor modelling of a unit process.
enumeration
Unit process(es), single operation
The review is done on the level of the "Unit operation type unit process(es)" that can not be further subdivided. Covers multi-functional processesof unit operation type.
enumeration
Unit process(es), black box
The review is done on the level of process-chain(s) or plant level unit process(es). This covers horizontally averaged unit processes acrossdifferent sites. Covers also those multi-functional unit processes, where the different co-products undergo different processing steps within the blackbox.
enumeration
LCI results or Partly terminated system
The LCI result or Partly terminated system is the level of review/verification.
enumeration
LCIA results
The LCIA results of the LCI result or Partly terminated system data set are reviewed/verified, i.e. on level of Climate Change potential, Primaryenergy consumption, Ecosystem damage etc. [Note: see also definition for entry "LCIA results calculation".]
enumeration
Documentation
The reporting/documentation of the process or product system, i.e. the data set's sections "Process description", Modelling and validation" and"Administrative information" have been reviewed, while this does not include the "Inputs/Outputs". This can include a review of detailed backgroundreports.
enumeration
Life cycle inventory methods
The application of the LCI method(s) in accordance to the goal and scope have been reviewed. This covers data collection including dealing withmissing data, data calculation/modelling principles (e.g. consequential or attributional or other/combination), and the application of the related modellingapproaches such as allocation and system expansion etc. for the process / throughout the product system.
enumeration
LCIA results calculation
The selection and application of the LCIA method(s) that have been used for calculation of the LCIA results have been reviewed. This especiallyrefers to a correspondance of the elementary flows in the Inputs and Outputs of the product system with the once referenced by the applied LCIA method(s)regarding e.g. correct assignment, coverage/gaps, doublecounting, etc. [Note: See also definition for entry "LCIA results".]
enumeration
Goal and scope definition
Review/verification is done regarding e.g. goal definition, subsequent scope definition and corresponding product system description, appropriateidentification and definition of function and functional unit, system boundary and cut-off criteria setting, choice of appropriate LCI modelling principles andapproaches for multi-functional processes.
