Biodiversity loss poses profound ethical questions for business, yet B2B marketing scholarship has largely overlooked it. Grounded in Resource-Advantage theory (Hunt, 2015), we develop an ethical architecture for biodiversity-centric B2B marketing and introduce "trust in systemic change" — stakeholders' confidence in firms' commitment to nature-positive transformation. Using 4,142 pharmaceutical sites across 40+ countries, we present a Global Corporate Site Biodiversity Index (CSBI) demonstrating how open-access biodiversity data serves as a strategic enabler aligned with compliance frameworks.
The framework bridges ecological accountability and stakeholder perception, establishing how measurable site-level biodiversity action translates into societal trust through verifiable, data-driven evidence of nature-positive performance.
The CSBI integrates environmental and biodiversity data into a single site-level metric, standardised from 0.01 to 99.99:
Part A (70%) — 7 indicators: Water Availability, Water Condition, Air Condition, Wildfire Hazard, Plant/Forest/Aquatic Pests & Diseases, Land/Freshwater/Sea Use Change, and Pollution.
Part B (30%) — 2 indicators: Biodiversity Intactness Index (BII 2020) and Bioclimatic Ecosystem Resilience Index (BERI 2020).
CSBI significantly predicts site-level reputational capital (β = .46, t = 31.27, p < .001), demonstrating that biodiversity-related intangible resources — trust, ethics, and sustainability legitimacy — translate into competitive advantage through verifiable, data-driven evidence of nature-positive performance.
BioDivIQ is a science-based platform using open-access ecological datasets to deliver biodiversity insights and CSBI scores across sites.
Practical implications:
A. Diagnose portfolio positioning on the defensive-to-proactive continuum
B. Interrogate greenwashing via the 4-matrix framework of corporate sustainability
C. Enable verifiable biodiversity claims through open data
D. Embed nature into capital allocation via biodiversity-linked financial instruments and digital asset innovation
