The category could be relevant for other product groups setting criteria for e.g. conflict minerals both in the voluntary instruments but also in the IM of the Ecodesign Directive. Setting this type of requirements in the Directive would require that supply of sustainably sourced materials could keep up with an increase in demand. An example is the Nordic and EU Ecolabelling criteria for imaging equipment, where a more efficient use of paper and ink cartridges is promoted. These types of requirements are already included in the draft of the Voluntary Agreement for imaging equipment within the Ecodesign Directive (duplex availability, default duplex setting, and information requirements targeting resource efficiency).270 However, the category is also highly relevant for other product groups.
