We engage with our key suppliers on decarbonisation matters as part of our supplier engagement and procurement strategy. In 2024, we have extended these engagements to also include resource use and circularity matters. These two topics naturally overlap as we are looking for opportunities to, for example, source more scrap steel as a means of increasing our usage of lower-emissions steel. As our negative impact occurs outside our own operations, we are dependent on continuous collaboration to make meaningful progress that will mitigate both the material negative impact as well as the risk related to our reliance on virgin scarce resources, when constructing our renewable energy assets. As an example of the supplier engagement programme development, we initiated a collaboration with wind turbine manufacturer Siemens Gamesa to use recycled glass fibres for certain new wind turbine blades at our Greater Changhua 2b and 4 offshore wind farms in Taiwan. The intended outcome of our supplier engagement and procurement strategy is to have a firm set of circularity-related supplier requirements in place within the next four to five years. For selected components, recycled materials have already been introduced as a sourcing evaluation criterion, ensuring our gradual transition away from the use of virgin resources.

To govern the identified risk and negative value chain impact from using virgin materials, we have adopted a 'Resource management policy', covering all of our activities and locations. The policy's objective is to ensure that we minimise the use and depletion of virgin resources by developing circular value chains together with our suppliers, where feasible, and guide our efforts on sustainable sourcing. It further addresses our adherence to the waste hierarchy, prioritising waste avoidance by reducing and reusing before recycling.
