Opened and checked on 2026-09-01. The 2024-25 release covers 208 facilities with total covered emissions of 132.8 Mt CO2-e against total baselines of 126.2 Mt, records 10.8 million ACCUs and 2.6 million Safeguard Mechanism credits surrendered, and reports 205 of 208 facilities compliant. It is accompanied by a data insights paper.

This entry exists partly as a correction. An earlier draft of this project's federal research asserted that the joined-up view -- baseline, covered emissions, onsite abatement and offsets in one place -- was not published. It is, as a CSV, and the assertion had been made without opening the data page.

The CER also publishes the method under which surrendered ACCUs were created, and requires facilities surrendering 30 per cent or more of their baseline to file a published statement explaining why more onsite abatement was not undertaken. That is a deliberate design against the exact criticism the scheme attracts.

CORRECTION, 2026-09-03. This record previously carried a last_checked date and, in the safeguard case, a confidence of verified. Neither was earned. The underlying data file was never downloaded; the record was written from the regulator's web pages and from reporting about them, which is reported at best. Both have been reset.

The scoring inputs are the part that matters, because they drive the usability score this project uses to judge everyone else. open_licence is supported -- Clean Energy Regulator datasets on data.gov.au carry CC-BY-3.0-AU. format and machine_readable are not confirmed. The regulator's data pages are client-side applications with no static file links, and the eight CER datasets listed on data.gov.au resolve to shapefiles, a web map service, and HTML landing pages rather than to the tabular file this record asserts.

The data is very likely downloadable as a spreadsheet through the site's own interface, and that is exactly the kind of assumption this register is supposed to refuse. The claim stands as reported and unverified until someone opens the file.

Third attempt, 2026-09-03. The data page was fetched and inspected. It loads its table through an AJAX endpoint rather than serving a file, so the baselines and emissions data still has not been opened and format and machine_readable remain unconfirmed. Confidence is lowered to estimate accordingly: reported would imply the format claim came from documentation, and it did not -- it was inferred.

One thing was confirmed directly. The page carries a per-facility table of 30 per cent explanation statements, each named and individually downloadable, beginning with Ashton Coal Mine (Underground). The requirement that facilities leaning hardest on offsets publish a written justification is real and the documents are there.

The headline figures this project has quoted -- 208 facilities, 132.8 Mt covered emissions, 10.8 million ACCUs surrendered -- do not appear on this page and come from the regulator's news and insights publications, which have not been opened.

Fourth attempt, 2026-09-03, via the Internet Archive's URL index rather than the live site. That index lists real files served from cer.gov.au under /DocumentAssets/Documents/, including "Postcode data for small-scale installations - all data.xlsx", "Postcode-data-for-small-scale-installations- SGU-Solar.csv" and "2021-22 Safeguard facility data.xlsx".

Those filenames are documentary evidence that this data is published as spreadsheets and CSVs, which is better support for machine_readable than anything the record previously rested on, so confidence returns to reported. The bytes themselves still could not be retrieved: the paths now redirect to the current site, and the archive did not return the stored copy either. Four routes tried -- direct fetch, the data page, data.gov.au, and the archive.

The register should be able to live with this. The claim is supported by a file listing rather than by the file, that distinction is recorded, and last_checked stays empty because nobody has opened it.
