Rainwater Harvesting on Site In 2022, our Marine business in Singapore installed a rainwater harvesting system onsite to collect, store and treat rainwater. The treated rainwater is used in place of potable water for instances like irrigation and cleaning. We continue to: • Install water saving devices such as water thimbles and flow reducing valves • Promote water conservation awareness through toolbox briefings and campaigns • Perform regular checks to detect leakages in pipes and faucets • Optimise our operations to reduce usage of water • Install rainwater harvesting systems and review water recycling options • Keeping all noise within legal limits and within permitted hours • Replacing noisy equipment with quieter models and providing sound insulation where applicable • Monitoring and reviewing noise emission levels from our operations • Conducting boundary noise checks in accordance with regulatory guidelines OUR GOVERNANCE AND FRAMEWORK OEST – Environment oversees the Group’s environmental protection efforts, provides a platform for business areas to share best practices, advises the respective management teams, and manages and coordinates key environmental initiatives across the Group. OEST – Environment supports the OESC Chairman who reports to the OESC Executive Sponsor. The OESC Executive Sponsor is a member of the Group’s senior management. The team comprises representatives from each business area who focus on data gathering, reporting and initiatives for: • GHG emissions (absolute Scope 1, 2 and 3 emissions; emissions intensity) • Energy (from fuel, electricity, heating and cooling) • Water (water intensity; recycling) • Waste (waste generated; recycling) Our integrated Environment, Health and Safety policy and Environmental Pledge sets out our environmental expectations and standards. Read our Environment, Health and Safety Policy We Manage Waste and Effluent We strive to reduce our waste generated in our business and regularly promote 3R (Reduce, Reuse and Recycle) initiatives. We redesign processes to reduce the generation of waste, toxic waste and effluent. In our Singapore operations, we target to maintain a recycling rate of 50% or better. Recyclable waste materials are collected by licensed waste contractors for recycling. In 2022, our Singapore operations recycled 75% of 26,900 tonnes of waste generated. The recyclables included metal, wood, batteries, e-waste and paper products. Any toxic waste generated is handled in accordance with local laws and regulations. For example, all toxic waste in Singapore is registered with the National Environment Agency’s e-consignment system that allows for the tracking of the quantity, characteristics and movement of the toxic waste from the organisation to the collector, and finally to the disposer. We adhere to all applicable laws and regulations regarding effluent discharge in areas which we operate. For example, in our Singapore operations, we comply to the minimum effluent standards set by the Public Utilities Board, National Environment Agency and the Maritime Port Authority, which differs depending on the type of waterbody that we are discharging to. We employ the use of dilution tanks, sensors, oil interceptors and pre-treatment of our effluents prior to discharge to ensure that we meet all applicable regulations. We Strive to be a Good Neighbour We aim to mitigate the noise generated by certain segments of our operations. Our measures include: 8 Based on waste collected and recycled in our Singapore operations.
