Refrigerant & F-Gas GWP Values

51 refrigerant & f-gas gwp values held in the GreenCalculus MasterBrain, drawn from Ipcc Ar6; Eu F Gas Reg 2024. Values are read live from the data layer on every page build, so nothing here is re-typed and nothing can drift from the figures the calculators use. All are expressed in kg CO2e per kg leaked.

Where these factors are used

Refrigerant Leakage Methodology sets out how factors in this group are applied, and Scope 1 Refrigerant Leakage Calculator and Scope 1 F-Gas Inventory Aggregator draw on them directly. The published dataset these rows are drawn from is Refrigerant & F-Gas GWP Values, which carries a DOI for citation.

What this group contains

Figures are computed per unit and never blended: a median across different units would be arithmetically valid and physically meaningless.

What has changed

Change history is reconstructed from every released edition of the data layer, v2025.13 to v2026.107. A factor absent from this table has held the same value throughout. A change shown as a dash moved off zero, where a percentage has no meaning.

Sources, citation & machine access

Cite the upstream publisher for the values themselves. The reference below credits this compilation and, more usefully, pins the edition you read.

Values change between editions. Quoting the MasterBrain version is what lets a reader resolve the exact number you used — see the change record above for factors in this group that have moved.

Or the same rows as a spreadsheet — every factor with its source, the edition it last changed in, and its own link:

Both responses carry an X-GC-Version header, so a consumer can detect a new edition without diffing the payload. The CSV filename carries the edition too, so two downloads months apart do not collide.

All factors

Last changed names the data-layer edition in which a factor last took a new value, reconstructed from every released edition since v2025.13. A dash means the value has not moved since tracking began — which is the answer to "is the figure I used last year still current?".
