Wheatstone Operations — Safeguard baseline, covered emissions and modelled path to FY2034-35

Current position · FY2024-25, as published

Current position

Published register values. The baseline is the emissions limit the rules set for the facility; covered emissions are the scope 1 emissions it reported. A facility above its baseline must surrender Safeguard credits or ACCUs for the difference. A facility below its baseline may receive Safeguard credits, subject to the crediting rules.

Composition of covered emissions by gas

The register reports covered emissions by greenhouse gas. At this facility carbon dioxide accounts for 92.84% of the total. The gas mix helps indicate which types of abatement may be relevant, although it does not identify the emitting process.

Greenhouse gas	t CO₂-e	Share
Carbon dioxide	3,732,749	92.84%
Methane	282,493	7.03%
Nitrous oxide	4,880	0.12%
Other	545	0.01%

Units surrendered and issued

Only the register lines with a value for this facility are shown. A line that is blank in the register is omitted rather than shown as zero.

Change since previous year

FY2023-24 to FY2024-25

Both years are published register values for the same facility name; no modelling is involved. Covered emissions rose relative to the baseline, so the gap below the baseline changed by 229,396 tonnes. The baseline falls each year by rule; covered emissions change for facility-specific reasons.

	FY2023-24	FY2024-25	Change
Covered emissions (t)	4,065,836	4,020,667	−1.1%
Baseline (t)	4,299,587	4,025,022	−6.4%
Position (t)	-233,751	-4,355	229,396

Official Both rows are published register values. The two years are matched by facility name only. Facilities are sometimes renamed between years, and a renamed facility appears as one facility leaving the register and another entering it. The Atlas method page lists the name pairs that have not been verified.

Modelled pathway

The baseline path to FY2034-35

Under the Safeguard Rule a baseline is production multiplied by an applicable emissions intensity and by the emissions reduction contribution (ERC). The ERC is the part that falls each year: by 0.049 per year to FY2029-30, and from FY2030-31 by the post-2030 decline rate. This facility holds no trade-exposed baseline adjustment determination and follows the default path. The controls below change the rate and the production assumption; the chart and figures are recalculated for this facility.

Post-2030 decline rate, percentage points per year

Production

Modelled The path scales the published baseline by the change in the ERC. It is not a compliance determination and not a forecast of the facility's emissions: covered emissions are held at the FY2024-25 level and adjusted only by the selected production assumption. The Regulator's published baseline governs.

Peer comparison

Facilities in the same reporting category

The FY2024-25 register includes 27 facilities in this reporting category (Oil and gas extraction (070)). The median one reported 312,681 t; this facility reported 4,020,667 t, above the median. The category is a reporting classification rather than a description of the process. Two facilities with the same code may operate different plant, so the comparison is indicative only.

Facilities of similar size in the same reporting category: Start up and Operations of the Ichthys LNG Project (6,255,335 t), North West Shelf Project (5,750,304 t), FLNG (2,253,798 t), APLNG Facility (2,206,497 t).
