How can businesses assess their biodiversity footprint? The 2025 Annual Plenary of the B4B+ Club, organised by CDC Biodiversité and hosted at La Banque Postale’s headquarters, brought together 80+ representatives from companies, financial institutions, NGOs and public authorities to tackle this urgent question. The event marked a turning point with the exclusive preview of the Global Biodiversity Score (GBS) online platform—a tool designed to standardize biodiversity footprinting —and debates on biodiversity strategies and enabling financial instruments.
A landmark event for biodiversity accounting
The 2025 B4B+ Plenary underscored the growing urgency for businesses to quantify and mitigate biodiversity impacts. Held in Paris on October 3, 2025, the event was co-hosted by CDC Biodiversité and La Banque Postale, gathering CEOs, financial regulators, and sustainability leaders to share progress on:
- Standardized biodiversity accounting (aligned with the Kunming-Montreal Framework).
- Corporate case studies (e.g., Groupe ADP’s and NaTran’s strategies from biodiversity footprinting to renaturation).
- Financial innovations, including biodiversity-themed funds (discussed by AMF and BDF Gestion).
The Global Biodiversity Score (GBS): A game-changer for transparency
The star announcement was the launch of the GBS online platform, a tool to help companies:
✅ Assess dependencies/impacts on biodiversity across value chains.
✅ Benchmark performance against sectoral peers.
✅ Align with global targets as well as regulatory and voluntary framework (CSRD, TNFD)
Corporate leadership: from measurement to action
The 2025 B4B+ Plenary highlighted two key pillars for advancing biodiversity: financial mechanisms and corporate strategies. During the roundtables, Groupe ADP and NaTran shared insights on their end-to-end biodiversity strategies, from footprint measurement to concrete renaturation actions, demonstrating how businesses can translate commitments into on-the-ground impact while the AMF and BDF Gestion stressed the need for dedicated biodiversity funds and anti-greenwashing safeguards. The European Investment Bank (EIB) concluded the event, emphasizing the need to facilitate the emergence of a biodiversity credit market, exploring frameworks to scale investments in nature restoration.
2026 Outlook: sectoral collaboration and scaling up
As the B4B+ Club celebrates its 10th anniversary in 2026, it will deepen sectoral collaboration with the launch of two thematic working groups: construction in Q1 and textile in Q2, tackling each sector’s unique biodiversity challenges. Club members will also gain exclusive access to the GBS platform, alongside a roadmap of new developments—including enhanced user experience and action-oriented tools—to empower businesses in measuring and reducing their biodiversity impacts. More innovations to come!
