ST Engineering Sustainability Report 2021

GROUP-WIDE ECO-INITIATIVES ENVIRONMENTAL → Environmental Protection 1) Conserve We focus on using only what resources we need and are constantly looking for ways to reduce our environmental footprint. Many business units across the Group have installed energy efficient fittings such as smart lighting and motion sensor water taps to conserve electricity and water. Units also renewed their conservation publicity drives to remind all staff to switch off lights when not in use. Other efforts implemented include: • Installation of smart meters to detect water leakage and provide data on the consumption profile, which is analysed to help develop more targeted initiatives • Use of data analytics to optimise the energy consumption of building cooling systems • Digitalisation (e.g. QR codes in offices, sites and at events to reduce the use of paper) 2) Bring-Your-Own Across the world, our units are phasing out the use of single-use plastics, including styrofoam packaging and bottled water at our canteens and meeting rooms. We provide environmentally friendly alternatives to plastic disposable cups in meeting rooms, while others bring their own mugs. Our colleagues bring their own F&B containers for takeaway, and many of the units have pantries where dishware and utensils are available. ST Engineering expects our employees across our global business units to be responsible for sustainability. In 2021, we launched the Group-wide Eco-Initiatives to enhance eco-consciousness and reinforce the existing ecopractices across our global operations. This focused on three areas of stewardship, attitudes and actions. 3) Recycle We are streamlining the way we track the waste we generate. Where possible, we reuse and recycle. This is part of our commitment to a circular economy approach to our business operations – doing our part for our planet and communities, while improving our cost efficiencies. We carried out two e-waste initiatives: • Collection and consolidation of used company and employees’ electronics in Singapore and Thailand – We donated more than 1,000 decommissioned laptops to Engineering Good, an NGO in Singapore and to Mirror Foundation, an NGO in Thailand; – Laptops are refurbished and will be distributed to school children from low-income families and to other charitable causes. • Facilitation of recycling used electronics – Provision of segregated e-waste receptacles across our sites in Singapore; – E-waste brought by employees was sent for recycling together with our appointed waste collection vendor; – More than 1.5 metric tons of e-waste recycled. 19 ST ENGINEERING SUSTAINABILITY REPORT 2021 OVERVIEW OUR SUSTAINABILITY APPROACH ENVIRONMENTAL SOCIAL GOVERNANCE AWARDS INDEX
