The materials wasted during construction, operation, and decommissioning constitutes a negative impact. In general, we see two complementary pathways to address waste generation that we must work on simultaneously. Firstly, we must consider if our waste generation can be avoided in the first place, by addressing the challenges at their root cause. This is done as we work to design our assets with minimal reliance on the use of a specific material, for example by switching non-recyclable content with more recyclable content to allow for proper waste treatment. At the same time, we need to ensure that waste is diverted from disposal by enhancing sorting and collection processes as well as supporting the maturation of reuse and recycling markets for our components and materials.

Waste is generally reported on the basis of invoices received from waste recipients, supplemented with plant-specific measurement methods for commercial facilities, including construction activities. Part of the oil-contaminated wastewater from the North Sea oil pipeline has been treated as waste and therefore reported as waste and not wastewater. Residual products, e.g., gypsum from the CHP plants, which are not handled as waste but sold as products, are not included. Soil from excavation projects is not included.
