CSL Limited Annual Report 2022/23 47 Environmental trends Compared with the prior year, total Scope 1 and 2 greenhouse gas (GHG) emissions reduced as CSL moved to increase the proportion of purchased electricity from renewable sources in Europe. This is notwithstanding the acquisition of CSL Vifor and increased production volumes at some locations. There were modest increases across energy and water consumption, with total waste and the proportion of waste recycled also increasing. This upward trend results from the addition of CSL Vifor and the waste solvent generated at that facility, as well as waste solvent from CSL Behring sites, which is subsequently recycled either onsite or offsite. Our environmental performance includes data from the following operations: • CSL Seqirus, three manufacturing facilities – Australia, the UK and the United States; • CSL Behring, five manufacturing facilities – Australia, Germany, Switzerland, the United States and China; • CSL Vifor, one manufacturing facility – Switzerland; • CSL Plasma operations, including plasma centres, across China, Germany, Hungary and the United States and two major plasma logistics centres, CSL Plasma laboratory and CSL Plasma’s saline manufacturing facility also in the United States; • administrative and R&D operations co-located with our manufacturing facilities; and • the respective head offices for CSL Behring (King of Prussia, United States), CSL Plasma (Boca Raton, United States) and CSL Limited (Parkville, Australia). This year we have also sought limited assurance on energy consumption and emissions data, including baseline data used for the establishment of our emissions reduction targets.

Utility invoices were used to establish these factors and calculate natural gas, electricity and water consumption for all CSL Plasma centres. Utility invoices were also used for CSL Plasma Logistic centres, CSL Plasma Laboratories and the Union manufacturing facility (United States). CSL Plasma uses the contracted waste hauler monthly data to calculate the total yearly waste impact. In the absence of hauler information, a factorial is applied to calculate the estimated waste impact per volume of plasma collected. 3 Includes CSL Vifor manufacturing facility in Switzerland following acquisition in August 2022. 4 The majority of greenhouse gas (GHG) emitted from CSL’s operation is carbon dioxide (CO2). In most jurisdictions GHG emission factors used by CSL calculate carbon dioxide, nitrous oxide and methane emissions. Total emissions are expressed as carbon dioxide equivalents (CO2-e). 5 Includes Scope 1 and 2 energy sources. Scope 1 energy sources are fossil energy sources supplied or used onsite, including fleet fuel use. Scope 2 energy sources are electricity and steam supplied to site, as well as chilled water and compressed air. 6 The recycling rate represents the proportion of total waste generated that is either reused or recycled onsite or offsite. * Limited assurance by Ernst & Young. CSL’s Scope 1 and 2 emissions profile Scope 1 greenhouse gas emissions are direct emissions from CSL activities. CSL’s Scope 1 emissions primarily come from the combustion of fossil fuels. The greatest proportion of these emissions come from burning natural gas to generate steam at manufacturing facilities. Scope 2 emission are from purchased electricity and to a lesser extent purchased steam, cooling water and compressed air. Manufacturing sites in Germany, Switzerland and the UK currently purchase electricity specifically from renewable sources. In 2022/23, 17% of the electricity purchased by CSL was from renewable sources. Scope 2 66% Scope 1 34% CSL Limited GHG (CO2-e) 2022/23
