Setup → Library (Reference library) shows which release of the reference library is pinned for each reporting year. A release contains the emission factors, GWP sets and other reference data. Each year is calculated with one pinned release, so a new release never changes past years silently.
Change the release for a year
- Under Change the release for a year, choose the Reporting year and a release (Choose a release).
- Click Preview impact. A dry-run calculation compares the current and candidate totals per asset and lists missing factors and findings. Nothing changes yet.
- Click Confirm and recalculate to pin the release and queue the recalculation of that year only.
Only client admins and methodology owners can change pins. A year with locked months refuses the change until a restatement reopens them.
Where the reference data comes from
The reference data is maintained centrally by the support team and published as releases. Factors are loaded only from published or licensed sources, with their reference and licence, and stay unverified until a subject-matter expert has checked them. See Emission factors.
