Data for 2020 and 2021 were scoped to WSC’s Energy Solutions Services Division only. We have considered the effects of decarbonisation on the value of our assets over the short, medium and long term and recognise the importance of considering climate-related impacts and opportunities across our business. WSC’s key strategic priority is the transition to a low-emissions energy sector. We actively monitor the latest global climate change science published by leading international organisations to help assess potential risks and opportunities for our portfolio. We seek to manage our portfolio to be resilient to adapt to a fast-moving energy transition and the increasing expectations of our stakeholders. We are continuously improving how we identify, assess, manage and govern climate-related risks and opportunities for our business. Wah Seong Corporation Berhad Annual Report 2022 24
