From pilot to policy: HEMA's nature journey with Spirefly
HEMA is a hundred years old, runs more than 700 stores, and sells almost everything a household needs: food, fashion, cosmetics, electronics. With SBTi targets committed, a solid set of sustainability KPIs, and sustainability linked loans in place, HEMA has turned ambition into accountability. Their 2025 sustainability report is the first to publish a nature assessment across the entire assortment. Five nature impact and risk categories, scored across 40,000 products, aligned with the Science Based Targets Network (SBTN) and the Taskforce on Nature Related Financial Disclosures (TNFD). Spirefly is the platform behind it. For HEMA's Head of Sustainability, Marieke Doolaard, sustainability is not a side project. This is the story of how HEMA went from a first nature pilot to a public policy backed by data, and how Spirefly helped make that possible.
