Metrics and Targets 32-34

Greenhouse Gas Emissions

Scope 1 and 2 Emissions Performance:

2025 Achievement:

• Net emissions reduction: 42% reduction in Scope 1 and 2 net emissions (equity share) from baseline year of 2019-20
• Target achievement: Achieved 2030 Scope 1 & 2 net equity emissions target in 2025, completing the target early

Scope 3 Emissions: Santos reports on Scope 3 emissions as detailed in the mandatory Sustainability Report. The company has set a target to reduce customers' Scope 1 and 2 emissions (Santos Scope 3) by at least 1.5 million tonnes per annum of CO2e from the supply of low carbon fuels and carbon management services by 2030.

Carbon Storage Impact:

• CO2e stored: 1.23 million tonnes of carbon dioxide equivalent stored at Moomba CCS project (total operated basis)
• Equity share stored: 0.82 MtCO2e (Santos equity share)
• Carbon credits: 907,872 ACCUs received for Moomba CCS operations

Emissions Reduction Initiatives:

• Moomba CCS: Operating to plan, safely and permanently storing CO2
• Energy efficiency projects: Ongoing across operations
• Use of renewables: In operations where feasible
• High integrity emissions reduction units: Supporting overall emissions reduction strategy

Future Targets:

• By 2030: 30% reduction in Scope 1 and 2 emissions (equity share)
• By 2030: 40% reduction in Scope 1 and 2 emissions intensity (equity share)
• By 2030: Near-zero methane emissions
• By 2040: Net-zero Scope 1 emissions (equity share)
• By 2050: Net-zero Scope 2 emissions

As detailed on page 38 the Group has applied the operational control approach to determine its organisational boundary for reporting GHG emissions. The Group measures its Scope 1 and Scope 2 GHG emissions in accordance with our obligations under the National Greenhouse and Energy Reporting Scheme.

Although disclosure of Scope 3 GHG emissions is not required for this Sustainability Report under AASB S2, the Group has elected to provide this information on a voluntary basis.

Where disclosed metrics are derived from activity data and third‑party emissions factors, they are subject to inherent measurement uncertainty.

PwC provided limited assurance over specific Sustainability Report disclosures in accordance with ASSA 5010 timelines with the exception of Scope 1 and 2 GHG emissions for which PwC provided reasonable assurance.
