omo Chemical's interest in New Zealand Aluminium Smelter (20.64%) and Boyne Smelters (2.46%), taking NZAS equity to 100% and BSL to 73.5%. Equity increase for the Ranger mine to 98.43%. Divestment of Lake MacLeod Dampier salt operations (removal from the baseline). 1. Rio Tinto share (equity basis) as a Baseline represents emissions from our benefit or economic interest in the activities resulting in the emissions. Emissions accounted for represent current equity and ownership for the full year. 2. The baseline value is based on the current equity in each asset, including zero equity in divested assets. Scope 2 emissions in the baseline are calculated using the market-based method. 3. Carbon credits used towards our 2024 net emissions calculation include Australian Carbon Credit Units (ACCUs) that were retired for compliance for the period 1 January to 30 June 2024 plus a projection of the number of ACCUs we expect to retire for the period 1 July to 31 December 2024. This projection is based on our Scope 1 emissions for the period 1 July - 31 December 2024. Rio Tinto retires ACCUs for liability under the Australian Safeguard Mechanism. Baselines for sites are calculated using known production intensity factors combined with actual reported production. Liability is determined when actual emissions exceed these baselines. Due to the misalignment of timing (Safeguard being July-June), carbon credits reported against the net emissions number include actual ACCUs retired for liability in the Jan-Jun 2024 part of the reported NGER FY24, and calculated liability using actual production and emissions for Jul-Dec 24. For details, refer to the table "Carbon credits retired towards net emissions (equity basis)" in our 2024 Sustainability Fact Book .
