CSL Annual Report 2026

Capital deployment Climate-related risks and opportunities are addressed through established business-as-usual processes, supported by financial budgets. Excluding investments in our transition plan expenditure, no material direct resources specifically attributable to the implementation of climate-related initiatives were deployed during the reporting period. Investments for our transition plan are the capital expenditure, financing or investment deployed to support CSL’s science-based target (Scope 1 and 2) through the execution of our abatement levers. Capital allocation for activities under CSL’s transition plan are assessed on a case-by-case basis. Approval of capital allocation is dependent on the amount, with large projects overseen by the Investment Review Board. For the reporting period, capital spending on key initiatives such as energy efficiency projects and electrification of end-of-life equipment is immaterial. Operational spending covering the procurement of renewable energy certificates supporting renewable energy claims across our Australia, Europe, UK and US operations is embedded into asset OPEX budgets, and is assessed annually. For the reporting period, costs to support the procurement of renewable energy are below $1 million (costs include the purchase of large-scale generation certificates). Carbon price A carbon price was used in scenario analysis to identify potential climate-related risks and opportunities, and assessment of anticipated financial effects. Calculated financial effects for carbon pricing impacts are disclosed in the Transition Risk 1 table, under the Financial Effects section. CSL does not apply a shadow internal carbon price in decision making. Carbon prices used come from the NGFS Net Zero 2050 scenario. Basis of preparation, assumptions, estimates and significant judgements This disclosure contains forward-looking statements and estimations that involved significant assumptions regarding CSL’s strategy, climate resilience, targets and initiatives. While these statements reflect CSL’s current expectations, they are subject to uncertainty. For statements that involve significant judgements, estimates and assumptions, this is indicated in the report. In cases where CSL has not quantified anticipated effects due to significant measurement uncertainty, qualitative information is provided, together with an explanation of why quantification is deemed not decision-useful. Judgements In preparing this report, CSL exercised judgement to determine relevant climate-related risks and opportunities, and material information to disclose in accordance with AASB S2. CSL has used multiple climate-related scenarios and intends to follow up-to-date and recent internationally available guidance or science to support its assumptions and analysis. In identifying material information to include in the climate-related financial disclosures, CSL has applied significant judgements to identify decision-useful information and provide a transparent disclosure. Given the limited financial implications that CSL anticipates, it has determined it would be relevant for readers to understand the climate-related risks, mitigations and quantification of financial effects, although not material for the enterprise from a financial materiality threshold. CSL has determined there were no events or changes in circumstances that required reassessment of the scope of all affected climate-related risks and opportunities throughout the entity’s value chain. This will be reassessed annually. Time horizons In addition to the notes included in the report, we note the following in relation to the time horizons used for climate risk assessment and the determination of anticipated financial effects. Climate projections are reported using multi-year timeframes rather than a single calendar year. Physical climate risk indicators reported for a given future year (year X) represent average climate conditions over a defined multi-year period (typically a 20-year timeframe centred on year X), rather than conditions in that single calendar year. This approach reflects established climate-science practice. Climate change impacts are driven by long-term shifts in climate patterns and cannot be meaningfully assessed based on individual years, which may be strongly influenced by natural climate variability or short-term weather anomalies. Assessing climate hazards over multi-year periods provides a more statistically robust and comparable representation of expected conditions. Accordingly, results for a given reporting year should be interpreted as indicative of the typical climate conditions around that year, based on average conditions across the relevant 20-year period. This supports stable, decision-useful assessment of physical climate risks and is consistent with approaches commonly used in climate modelling and scientific assessments. Scenario analysis, resilience assessment and vulnerability metrics CSL has modelled its physical climate-related risks and opportunities for its 17 sites (including both manufacturing and storage sites8). This selection of sites has been used to estimate financial effects and to inform vulnerability metrics for physical risk exposure. For transition climate-related risk assessment and estimation of the financial effects of carbon pricing, CSL has modelled the carbon price across 10 sites (9 manufacturing sites and one aggregated site covering plasma collection centres). This data has also informed the associated vulnerability metric. 8. Assessed assets represent greater than 90% of CSL’s Total Fixed Asset Value, excluding leases and impairments. 153 CSL Limited Annual Report 2025/26
