102 YINSON HOLDINGS BERHAD | INTEGRATED ANNUAL REPORT 2024 Waste and pollutants monitoring Consistent monitoring of our waste and pollutants on board enables us to minimise Yinson Production’s environmental impact and ensure compliance with regulatory standards including the Integrated HSSEQ Management System and the internal processes outlined in our Yinson Management System (YMS). Our environmental performance dashboards offer updated, aggregated visualisations of environmental data. We have maintained a record of zero non-compliances to environmental laws and regulations for the year in review. Water and effluents Yinson Production’s operations generally do not heavily rely on shared water resources with local communities, whereby our primary source of freshwater consumption is from water utilities. Thus, we do not induce water strain on potable groundwater. Our FPSOs generate and release produced water, slop and seawater, which are utilised for cooling purposes, into the sea as part of our daily operations. During the process of oil & gas production, a significant amount of liquid discharge and produced water is generated. Following extraction, the produced water undergoes separation and treatment (de-oiling) before being discharged into surface water. The quality of produced water is assessed based on its oil content. Management of water discharge-related impacts The global minimum standard for produced water discharge, established by the World Bank Group, is set at less than 30 ppm, while the standard for slop water discharge, as per MARPOL requirements, is set at less than 15 ppm. We strictly adhere to these regulatory requirements and industry guidelines for all water discharges and have stringent pollution controls for all sea discharges. For FPSOs operated by Yinson Production, water discharge is only permitted if the oil content is less than 15 ppm in slop water and 30 ppm in produced water. In FYE 2024, the oil in slop water and produced water were 6.3 ppm and 14.3 ppm respectively from Yinson Production-operated FPSOs. Yinson adheres to a combination of international and local regulations along with industry best practices as the foundation of our engineering solutions. We rigorously comply with regulations and procedures including: • MARPOL – which limits discharges of potentially polluting substances into the waters where we operate and includes regulations to prevent pollution caused by oil, noxious liquid substances, sewage, garbage and air pollution. • The International Convention for the Control and Management of Ships’ Ballast Water and Sediments – aims to mitigate the adverse impacts of discharging ballast water in sensitive areas to prevent the release of foreign organisms into marine ecosystems. We regularly communicate with our stakeholders regarding any discharges of harmful substances, ensuring compliance with MARPOL and the International Convention on Oil Pollution Preparedness, Response and Co-operation. Yinson implements operational procedures and emergency response protocols to minimise risks associated with releasing water into marine ecosystems. We maintain unit-specific Shipboard Marine Pollution Emergency Plans (SOPEP) for both our offshore production and marine assets, detailing protocols for emergency preparedness in the event of harmful discharge incidents. During the year under review, our total volume of water (effluent) discharged was 2,642.5 ML. Air emissions Non-GHGs such as nitrogen oxides (NOx), sulphur dioxide (SO2), carbon monoxide (CO), and non-methane volatile organic compounds (nmVOCs) are linked to air emissions. These emissions are calculated based on activity data and conversion factors recommended by the UK Oil & Gas ‘EEMS – Atmospheric Emissions Calculations (Issue 1.810a)’. Strictly complying with regulatory standards, we diligently monitor and evaluate air emissions aboard our FPSOs to mitigate our carbon footprint. In line with our commitment to reducing air emissions, we prioritise the adoption of low-emission technologies whenever feasible on board our assets. In relation to these approaches, we are looking into decarbonisation solutions which relate to direct air capture and carbon removal, as well as other opportunities within the carbon value chain relating to transportation, infrastructure and storage.
