WWF's Nat 40 Index Reveals Top Brands' Supply Chain Exposure
France's 40 largest companies face substantial exposure through their supply chains according to WWF.
The organisation's Nature 40 (Nat 40) Index examined nature-related disclosures required under the EU's Corporate Sustainability Reporting Directive.
The assessment ranked each company on sustainability progress and initiatives. No company has developed a fully formalised Nature Transition Plan according to the findings.
Value chain transparency gaps
WWF evaluated several top performers whose business models depend on agriculture and natural resources. These included Kering, LVMH, Carrefour, L'Oréal, Hermès, Pernod Ricard and Danone.
The leading group demonstrates convincing materiality analyses according to the report. Their overall supply chains remain deeply vulnerable due to an overwhelming lack of granular location-specific data.
Corporate procurement policies appear to rely on vague voluntary certification schemes. These offer little evidence of effectively reducing ecological pressures according to WWF.
"Improving transparency, traceability and collaborative action in the value chain can help businesses address impacts and dependencies (well established)," writes IPBES, 2026.
Procurement and sourcing models
The Nat 40 Index ranks the 40 largest listed French companies based on information disclosed in their audited Universal Registration Documents. The methodology evaluates corporate disclosures across four nature-related dimensions of the European Sustainability Reporting Standards.
These dimensions cover pollution, water and oceans, biodiversity and the circular economy. The scoring framework evaluates the maturity of corporate practices across five core transition plan components.
Components include foundations such as double-materiality assessments, metrics and targets, implementation strategies, stakeholder engagement and governance. Each component receives scoring using a four-level maturity scale.
The scale ranges from Non-Aligned at zero and Compliant at one to Coherent at two and Credible at three. Individual evaluations aggregate into a weighted final score out of 100.
Resource extraction dependencies
Technology and high-tech defence infrastructure leaders such as Dassault Systèmes, Capgemini, STMicroelectronics, Thales and Orange exhibit an alarming underestimation of their direct and indirect footprints. Their growing reliance on data centres and advanced hardware places severe unmitigated pressures on freshwater resources and land take according to WWF.
The energy sector, represented by TotalEnergies and Engie, relies on critical metals and mineral resources sourced from global mining operations. These companies have not established reliable value chain traceability according to the findings.
Thales, Safran and STMicroelectronics fail to register biodiversity as a material factor. This occurs despite their extensive structural dependencies on natural resources.
"Nature loss is a material economic risk that urgently needs to be addressed, yet most major companies continue to treat nature decline – from biodiversity collapse to freshwater scarcity, soil degradation and the depletion of natural resources – as a peripheral topic rather than a core strategic issue," says Guillaume Wahl, ESG Expert at WWF France, in the Nat 40 Index.
Climate and ecosystem alignment
The report notes that climate disruption and biodiversity loss could be inseparable. These serve as twin dimensions of the same ecological crisis.
According to WWF, 80% of the 40 companies have established validated Science-Based Target initiative targets. Corporate strategy remains unsustainably asymmetrical, treating nature and ecosystem protection as secondary concerns.
"Biodiversity loss, air, soil and water pollution, the depletion of natural resources and ecosystem degradation jeopardise the stability of our societies and the resilience of our business models," says Alexandra Palt, President of WWF France, in the Nat 40 Index.
"Given these challenges, corporate responsibility is crucial. By analysing key themes – pollution, water, biodiversity and the circular economy – this report highlights encouraging initiatives but also reveals a persistent gap between stated commitments and the actions or resources actually deployed."
Financial sector blind spots
The banking and financial sector including Euronext, AXA, BNP Paribas, Crédit Agricole and Société Générale typically view all nature-related risks as non-material to their multi-billion euro investment portfolios. This represents a critical blind spot according to the Index.
"As the cost of inaction continues to rise, companies must move beyond risk mitigation and act guided by science to reduce their impact on nature," says Christopher Rannou, Senior Natural Capital Officer at WWF France, in the Nat 40 Index.
"Developing fully costed and financed nature transition plans is not just a signal beyond short-term profit, it is essential to align business practices with planetary boundaries, build resilience and secure a long-term licence to operate."
WWF urges businesses to deploy holistic transition plans that explicitly map out how their physical and financial operations aim to respect planetary boundaries. These plans should actively support international biodiversity frameworks to prevent severe greenwashing risks according to the organisation.
