Regulatory Reporting Thresholds

228 regulatory reporting thresholds held in the GreenCalculus MasterBrain, drawn from 19 named sources, each listed with its publisher and licence under Sources below. 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. They span 91 units of measurement — 56 of them in multiplier of required CII — which is why the spread below is reported per unit and never blended.

Where these factors are used

CSRD ESRS E1 Climate Disclosure and VSME Sustainability Reporting set out how factors in this group are applied, and CSRD ESRS E1 Climate Disclosure Calculator and GRI 305 Emissions Disclosure Calculator draw on them directly. Each value below names the upstream source it came from.

Figures are computed per unit and never blended: a median across different units would be arithmetically valid and physically meaningless. 49 further units in this group have fewer than 3 factors and are counted above but not described.

The download leaves out 131 rows from IMO_MEPC_354_78, IMO_MEPC_353_78, IMO_MEPC_364_79, IMO_MEPC_355_78 and 1 more, whose terms do not give us the right to pass their figures on in a file. They stay on this page, each beside its source, and in the endpoint above, where every row carries licence.redistributable. The per-publisher terms are on the sources register.

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.

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?".

Common questions

228 factors. They are read live from the GreenCalculus data layer on every page build rather than re-typed, so the figures here are the same ones the calculators use. They come from 19 named sources, each listed with its publisher and licence in the Sources section above.

Not without checking the unit first. This group spans 91 different units of measurement, the most common being multiplier of required CII. A factor is only meaningful against the activity data its unit describes, which is why the spread on this page is reported per unit and never blended into a single average.

None of the 228 factors here has changed value since tracking began. The Last-changed column shows a dash against every row for that reason. Change history is reconstructed from every released edition of the data layer, so a revaluation would appear there.

Every row has its own link. Click the canonical key in the last column and the address bar will hold an anchor for that one factor, so a citation resolves to the number itself rather than to a table someone has to search. Quote the data-layer edition alongside it (currently v2026.284) — values change between editions, and the version is what lets a reader resolve the exact figure you used.

Yes. This group is readable from an open endpoint with no key and no signup: https://greencalculus.com/wp-json/greencalculus/v1/factors/regulatory_thresholds. Responses carry an X-GC-Version header so a consumer can detect a new edition without diffing the payload. Cite the upstream publisher for the values themselves.
