Count an acquired business from the date you gain control. Count a sold business up to the date you lose control. Count a closed site up to the date it closes.

For an acquisition, use the acquisition date in your financial statements. Do not use a later date, such as the date the business moves onto your finance system, the date of "financial integration", or the start of the next financial year. If control passes before legal completion, use the control date that the accounts use. Then your emissions and your financial statements cover the same business for the same period.

Bluegum acquired 100% of Trailhead Rentals on 1 March 2026. Bluegum's consolidated accounts include Trailhead from that date. Bluegum's FY26 runs from 1 July 2025 to 30 June 2026.

So Bluegum counts Trailhead from 1 March to 30 June 2026. That is 4 months, or 122 days.

Trailhead's emissions from 1 July 2025 to 28 February 2026 belong to its previous owner. They are outside Bluegum's FY26 inventory.

Trailhead is a consolidated subsidiary, so it is in at 100% under financial control. Trailhead hires out its trailers and kayaks on operating leases. Under financial control those assets stay in Bluegum's Scope 1 and 2. See Assets you lease out to others.

Ask for the acquired business's data from the acquisition date. Use the date on each record:

If a source cannot be split, apportion the full year. Use a measure of activity if the business is seasonal. Trailhead's hire days from March to June were 20% of its FY25 total, so a split of 4/12 (33%) would overstate. Record the method you used.

If the business has no data at all, estimate for the months you owned it, then replace the estimate with real data next year. See Estimate what you cannot measure.

Count it up to the date you lose control. Get its data before completion. After completion, the buyer holds the records.

If you sell part of a subsidiary and keep a stake, the treatment changes on that date. Suppose Bluegum sold 50 of its 70 percentage points in Summit Packs on 31 March 2027 and kept 20% with significant influence:

See Joint ventures, associates, investments and franchises.

Count the site up to the date it stops operating. If energy is still used after that date, for example for security lighting or make-good works, count that energy until you sell the site or hand it back.

Closing a site is not a structural change. The emissions stop. They do not move to another company. Do not recalculate your base year for a closure.

An acquisition or disposal of an operation that existed in your base year is a structural change. Test it against your recalculation threshold. Trailhead's full-year FY25 emissions were 1,150 tCO2e, which is 5.8% of Bluegum's FY25 base year. That is above the 5% threshold, so Bluegum recalculates its base year. The workings are in Set a base year and recalculate it.

In your commentary, separate the two causes of change: changes in your operations and changes in your group. A reader cannot tell them apart from the total.

No. Your AASB S2 comparative is last year's figure as reported (AASB S2 Appendix D paragraph 70). An acquisition or disposal does not change it. This matches your financial statements.

You restate the comparative only in these cases:

Show any recalculated base year separately, and label it as recalculated. FY26 is Bluegum's second AASB S2 year. Its FY26 report shows FY25 Scope 1 and 2 as reported, without Trailhead. The recalculated FY25 base year, with Trailhead, is a separate figure.

In your first AASB S2 year, you need not show a comparative (C3). If you used the C4(b) relief in your first year, you need not show a Scope 3 comparative in your second year (C5). See Set a base year and recalculate it.

Yes. After a significant event, such as an acquisition, reassess which Scope 3 categories and which value-chain entities you include (AASB S2 B34). Run the relevance and materiality tests again for all 15 categories.

Trailhead buys trailers and kayaks every year. That adds to Bluegum's Category 2. Trailhead's hire fleet is on operating leases, so under financial control it stays in Scope 1 and 2, not Category 13. Record the reassessment and its result in your boundary document.

An event after your year end, but before you approve your report, changes your figures only if it gives new information about conditions at year end. An example is a corrected meter reading for June. Otherwise, do not change the figures. Disclose the event if it is material (AASB S2 Appendix D paragraphs 67 and 68).

Bluegum is negotiating to buy its partner's 50% of Coastline Kayaks. Suppose the purchase completes in August 2026, before Bluegum approves its FY26 report. The FY26 figures do not change: Coastline stays in Scope 1 and 2 at 50% for FY26. Bluegum discloses the purchase if it is material. See What goes in your boundary document.
