Purpose of the Data Quality Matrix
The Data Quality Matrix is a tool designed to systematically assess and communicate the reliability and relevance of the data sources used within our carbon calculator. It helps users understand the strengths and limitations of the underlying data by scoring key dimensions such as accuracy, completeness, timeliness, transparency, and geographical relevance.
Because our calculator aggregates data from diverse studies, inventories, and reports, the matrix ensures transparency about data quality and supports informed interpretation of the results. Importantly, data quality is not static—our data represents the best available information at the time but is continually updated as new research, improved measurements, or refined understanding become available.
It is worth noting that even data originating from the same source can receive different accuracy scores depending on the assumptions involved in its application. For example, while a base emission factor may be highly accurate - i.e. we have a good value for plastic - estimates involving assumptions - such as the quantity of plastic used in round bale wrap - can lower the accuracy rating for that specific item.
Accuracy (A)
This measures how close the data is to the real world value.
1 = Bad; placeholder value or guesswork
2 = Poor; rough estimate with significant assumptions
3 = Reasonable estimate or proxy with known limitations
4 = High confidence data with minimal assumptions
5 = Verified data from measurements or direct source
Completeness (C)
This looks at whether the data covers the full range of what's needed (e.g. all product types or categories) and all components of the emissions.
1 = Very incomplete; most options missing
2 = Significant gaps limiting coverage
3 = Partial coverage with some key data missing
4 = Minor gaps; mostly complete set
5 = Complete data set covering all relevant options
Timeliness (Ti)
This assesses how current the data is. Changing technologies and regulations are common in the climate field so keeping data current is key.
1 = Very outdated (20+ years) or no datestamp
2 = Old data (10–20 years)
3 = Moderately outdated data (5–10 years)
4 = Slightly outdated data (2–5 years)
5 = Current (within 1 year)
Transparency (Tr)
Evaluates whether the source, methodology, and assumptions are clearly stated and accessible.
1 = Not given; unknown origin
2 = Minimal documentation
3 = Known source but derivations unclear
4 = Source clear but some documentation missing
5 = Fully documented, public, and verifiable
Geographical relevance (G)
This indicates how well the data reflects UK systems.
1 = No specified region
2 = Global data
3 = Climate zone relevant
4 = Europe relevant
5 = UK specific data
