Impact story - IWB
SUPPLY CHAIN ACTIVATION: THE POWER OF COLLABORATION To address Scope 3 emissions and supplier responsibility, IWB launched a Value Chain Ac- tivation (VCA) with its key suppliers — one of the first of its kind in Switzerland. KEY ELEMENTS OF THE APPROACH • Use of the IntegrityNext platform for supplier self-as- sessments on CO₂, circularity, human rights, and safety • Collaboration with Elevate and Prozirkula for cate- gory-specific sustainability analyses • Integration of sustainability criteria into all major ten- ders (up to 40% weighting in procurement evalua - tions) • Workshops and peer exchanges with suppliers to share learnings and define measurable targets
BIODIVERSITY AND NATURE RES - TORATION In addition to its operational and supply chain goals, IWB invests in ecological restoration and nature-positive land management. Together with Pro Natura Baselland, the com- pany is developing over 30 hectares of new near-natural habitats — aiming for 50% of all IWB land to be certified as biodiverse by 2030. Roof greening projects and ecological corridors further strengthen this nature-based approach. Watch more: IWB biodiversity video
While supplier engagement remains challen- ging in some industries, the VCA has already improved transparency and fostered a culture of shared accountability.
« We realised that real climate impact requires collaboration. Through the VCA, we’re transforming our supplier relationships into partnerships for sustainability.» - Dietmar Küther, Sustainability Lead at IWB ”
