Yinson Integrated Annual Report 2025

87 INTEGRATED ANNUAL REPORT 2025 SUSTAINABILITY REVIEW | BUILDING ENVIRONMENTAL AND CLIMATE RESILIENCE WHY IS THIS TOPIC MATERIAL TO US? Energy infrastructure assets, such as FPSOs and solar and wind farms, are inherently resource-intensive to build, operate and decommission due to their scale and complexity. Their construction requires vast quantities of materials, including steel and silica, while their maintenance and operations over the asset lifecycle may consume more resources, such as water, especially if these assets are not designed with efficiency in mind. Prioritising efficient and responsible resource utilisation during both project development and operational phases is essential to ensuring that our assets contribute to economic growth without wasting natural resources. Resource-efficient energy infrastructure has the potential to drive long-term sustainable development. Efficient management of resources also confers a strategic business advantage, as optimising the use of raw materials and energy supports cost control measures in both construction and ongoing operations, while facilitating long-term robust environmental performance. MANAGEMENT APPROACH Yinson’s businesses require inputs from four primary resource categories: land, materials (including, fossil fuels, metal ores, and non-metallic minerals), water and energy. Our activities within these categories are closely connected to the UN SDGs that the Group has committed to supporting, specifically SDG 7: Affordable and Clean Energy, SDG 9: Industry, Innovation, and Infrastructure, SDG 13: Climate Action, and SDG 14: Life Below Water; as well as non-core SDG 12: Responsible Consumption and Production. Our approach to resource efficiency is outlined by a comprehensive strategy emcompassing planning, design, construction, operation and decommissioning. Asset design is integral to the resource efficiency of our assets. We adopt principles of sustainable design throughout asset lifecycle that consider the volume and sources of materials and natural resources. Additionally, we ensure construction processes are optimised to reduce resource usage and waste. Once our offshore production assets are operational, we maintain resource efficiency by monitoring and managing the resources used – a process enhanced through our focus on digitalisation and technology. These include energy management systems to monitor and control energy use, water-saving measures and waste reduction programmes. We prioritise a holistic asset lifecycle strategy, dedicating teams to ensure that our assets operate at optimal efficiency and prevent resource wastage. We plan ahead for the end of the asset’s lifecycle to ensure the decommissioning process considers materials that can be recycled or repurposed, while minimising environmental impact. Throughout the entire process, we engage with stakeholders to ensure the assets meet the production needs outlined by our clients and offtakers without compromising environmental and social integrity. FPSO conversion and redeployments A key advantage of FPSOs is their potential to extend a marine vessel’s useful lifespan significantly, either through conversion or redeployment to new fields. Yinson Production is experienced in conversion projects, where very large crude carriers (“VLCCs”) are converted into FPSOs. Conversion projects are considerably less resourceintensive than new builds. Using donor tankers for our FPSOs allows us to reuse steel from the hull, which our engineering teams factor into the design and conversion process. An FPSO redeployment involves modifying an existing asset to suit the specifications of the new field. This approach is also far less resource-intensive compared to a new build, as most materials can be repurposed, if designed well. Notably, redeployment avoids the need for decommissioning and dismantling, enabling the project to be generally executed in a relatively short timeframe, thus bringing forward production timeframes for our clients while reducing capital expenditure. ME5 Resource Efficiency Risks • Poorly optimised resource outlay into new projects may drive up construction costs and cause inefficiencies, affecting returns. • Over-reliance on specific resources increases vulnerability to supply chain disruptions or price fluctuations. • Ineffective resource management may increase the environmental impact of operations, contributing to higher emissions and waste. Opportunities • Innovative solutions to optimise resource utilisation, enabling the reduction of waste and minimising excess inventory. • A good track record of optimising resource use with minimal waste is a competitive advantage, attracting like-minded investors, clients, consumers and talent pool. • Avoidance of negative social and environmental impacts on local communities as a player who is conscientious about local resource use.
