ESR-REIT - Annual Report 2024

152 STRATEGICALLY ADVANCING SUSTAINABILITY REPORT Our Plan for Water Efficiency Improvement is as follows: 1. Smart Metering for Improved Tracking and Monitoring: We have launched a Smart Metering Replacement Program to digitalise data collection and trend analysis. By 2026, all Singapore properties will be equipped with smart meters integrated into our Integrated Utilities Management System (“IUMS”). This will streamline operational management, tenant billing, and provide real-time data analytics. This allows for continuous monitoring of consumption patterns, enabling comparisons across buildings and tenants, allowing our property managers to detect leaks early to prevent water wastage and improve efficiency. 2. Upgrading Water Fittings for Enhanced Efficiency: As part of ongoing AEI and property upgrades, we are planning the installation of water-efficient plumbing and sanitary fittings. Currently, 27 of our MTBs hold the WEB certification. Moving forward, we are reassessing and upgrading the plumbing and sanitary fittings with improved water-efficient level within our properties, ensuring compliance to PUB WEB requirement. 3. Education and Awareness Programme: Achieving water conservation goals require collaboration between ESR-REIT and our tenants. In addition to building system and fixture upgrades, we are actively engaging tenants through educational initiatives. These efforts are reinforced through our Green Lease clauses, which provide tenants with clear guidelines on sustainable water usage practices. These educational programmes will build upon existing initiatives and incorporate the insights gained from our enhanced monitoring capabilities to maximise their impact. MATERIAL TOPIC: WATER Targets Time Horizon 2024 Performance Obtain Water Efficiency Building (“WEB”) Certification for all MTBs in Singapore by FY2025 Short Term 27 out of 32 MTBs in Singapore are WEB certified as at FY2024 Achieve 14.0% water intensity reduction for Singapore MTBs’ common area with operation control by FY2030, compared to FY2023 Medium Term Water intensity decreased by 1.8% from FY2023 to FY2024 Impact of Water Management to Stakeholders The extent of water-related risks faced by ESR-REIT depends on the specific location of our properties and the nature of our building tenants’ operations. Water-related challenges such as contaminated water discharge and large water consumption may lead to increased costs and potential conflicts with local communities and regulations. How We Manage Water as a Resource In Singapore, we are aligning with national water conservation efforts by upgrading our buildings with water-efficient fixtures rated at 3-ticks under PUB’s Water Efficiency Labelling Scheme. To influence our tenants to conserve water, we provide guidance on the installation of water fixtures and behaviours to reduce water consumption within our Green Lease clauses. In response, we are implementing proactive measures to manage water consumption, including closely monitoring tenant activity levels, introducing educational programmes to raise awareness of water conservation and identifying potential water leakage risks to improve overall water efficiency across our properties.
