We know exactly where our wood comes from and require our wood suppliers to comply with our high standards. To achieve this, in addition to our internationally recognised seals of quality, we have developed a variety of our own control mechanisms that go far beyond those of the established certifications and which serve to guarantee the legality and sustainability of our forest management. For example, for regions from which we source a lot of timber, we commission universities to carry out independent studies that assess the sustainability of the goods sourced there. We also conduct random on-site audits in the actual forests.
