Emission Factor Licences 2026: 137 sources, source by source

One row per source holding rows in the GreenCalculus emission-factor corpus (137 sources, data version 2026.193): publisher, dataset, edition, the publisher's licence wording, a derived licence family, and the two permission questions people conflate — whether GreenCalculus may serve the values with attribution, and whether a third party may republish them onward — plus the reason where they differ, whether the publisher's own file is free or paid, the date the terms were read, the row count, and the publisher and explainer URLs.

No emission factor values are in this file. It is licence metadata: the answer to which datasets can I legally redistribute in a product? rather than the datasets themselves.

Columns

column	meaning
`source_id`	Registry key, stable across editions of the same publication family
`publisher`, `dataset`, `edition_year`	Who published it, what it is, which edition
`licence_wording`	The publisher's terms as transcribed in the registry; this governs
`licence_family`	Derived reading aid: CC BY, CC BY-SA, CC BY-NC, CC BY-NC-ND, CC BY-NC-SA, open government licence, public domain or public record, free with attribution, publisher copyright cited under fair use, bespoke terms, not stated
`served_by_greencalculus_with_attribution`	May the API and the site carry the values with attribution
`republishable_onward`	May you redistribute the values in your own product
`onward_restriction_reason`	Why the two differ, or why republication is refused
`publisher_file_cost`	`free` or `paid` for the publisher's own file
`terms_read_on`	The date the terms were read; a licence can change between readings
`rows_in_corpus`	Factor rows held from this source
`publisher_url`, `greencalculus_explainer_url`	The source and the explainer
`data_version`	The corpus data version this snapshot was taken from

How it was read

The licence wording is the registry's transcription of each publisher's terms; the family column is derived from that wording by pattern and the wording governs. Where a publisher granted GreenCalculus a permission that is not sublicensable, the two permission columns differ and the reason column says so.
