For video, audio and gaming products, based on the data inputs used, it was concluded that legal warranty period is the most appropriate data type for estimating products’ durability. We estimate that product durability for these products is equal to the warranty period at a minimum. In practice the products will often last longer than the minimum warranty period. The warranty period for these products differs, ranging from 1 to 5 years. Gaming and consumer products typically have 1-2 years warranty, video products typically have 2 years warranty, while selected Biz, BlueParrott and Engage headsets typically have 3 years warranty. Extended warranty services can increase warranty up to 5 years for selected products. For hearing aids, we design our products to minimum 5-year durability, which takes origin in the initial requirements for the minimum storage time for documentation in the Medical Device Directive. GN is therefore required to ensure safe and effective use of its products for at least 5 years, which is documented in our submissions to authorities as part of product approval.

All resource inflows metrics are estimated using our product lifecycle assessments (LCAs), as these contain verified component-level data, including material composition and measured weight. The LCAs we have available are allocated at the item level across the product portfolio. All LCAs are third-party verified according to ISO 14067. For products currently lacking an LCA, a reference LCA is allocated. Professional judgement is applied in the selection of a reference that will best represent the product or part. An uplift is conducted for items that cannot be represented by an LCA, based on the calculated average per unit volume purchased or produced. For Enterprise, Gaming & Consumer products, one unit packaging per unit product has been assumed.
