CapitaLand Ascendas REIT - Sustainability Report 2025

Commitment and Progress CLAR is committed to supporting CLI’s ambition to achieve Net Zero emissions by 2050. CLAR has tracked and disclosed its Scope 1 and Scope 2 emissions since FY 2014. Recognising that electricity consumption is the biggest source of its emissions, various strategies have been implemented to maximise energy efficiency in its electricity use. Apart from Scope 1 and 2 emissions, Scope 3 emissions constitute a substantial portion of the overall environmental footprint of its portfolio. Since FY 2023, CLAR commenced and expanded its disclosures on Scope 3 emissions, disclosing emissions associated with Category 3 (Fuel- and Energy-related Activities), Category 5 (Waste Generated in Own Operations), Category 6 (Business Travel), and Category 13 (Downstream Leased Assets). CLAR continues to expand its Scope 3 data coverage, enhance data quality, and collaborate with its value chain to drive decarbonisation. From FY 2025 onwards, CLAR expanded its Scope 3 emissions disclosure by covering Category 1 (Purchased Goods and Services), Category 2 (Capital Goods), Category 4 (Upstream Transportation and Distribution) and Category 15 (Investment). CLAR is also aligning its use of emission factors with CLI, sourcing emission factors from the International Energy Agency (IEA)25 2025 for FY 2025 reporting. IEA factors are increasingly regarded as a market standard in global ESG reporting and provides global coverage for more than 150 countries / regions. Standardising emission factors, instead of adopting country / region-specific emission factors offers comparability across regions / peers and within CLI Group. In FY 2025, CLI undertook a benchmarking study to review and assess industry best practices for accounting for energy and carbon emissions for data centre assets based on the operational control approach under the GHG Protocol. The new approach for allocating emissions for data centre assets is currently under review and will be updated accordingly. 25 IEA is an intergovernmental organisation that provides authoritative global energy data, analysis, and policy guidance to enhance the reliability, affordability, and sustainability of energy systems across more than 30 member countries and associated regions. 26 Refers to CLI 2030 SMP for more details: https://www.capitaland.com/content/dam/capitaland-sites/international/about-capitaland/sustainability/ revisedsmp/SMP_FINAL.pdf 27 Galaxis, Neuros & Immunos, Nexus @one-north, LogisTech, Nucleos, Cintech I, Cintech II and Rutherford and Oasis, Singapore. 28 Refers to CLAR owned and managed properties.
