Do Markets Respond to Corporate Biodiversity Initiatives?

Biodiversity Action on the Corporate Agenda  

As biodiversity loss rises on the global policy agenda, firms face growing expectations to respond. But do investors care? 

In a new working paper, Hossein Asgharian (Lund University), Michał Dzieliński (Stockholm University), Sara Jonsson (Stockholm University), and Lu Liu (Stockholm University) analyze firm-level biodiversity initiatives and their market consequences. 

“Using a unique dataset that defines sustainability initiatives as concrete firm-level sustainability actions, this study examines firms’ biodiversity-related initiatives, their links to underlying biodiversity risks, and whether financial markets value them,” the authors write. 

Drawing on text analyses of sustainability reports from approximately 4,000 listed firms, the study focuses on actions targeting Sustainable Development Goal (SDG) 14, Life Below Water, and SDG 15, Life on Land. 

The authors find that “biodiversity-related initiatives are concentrated in community engagement activities, such as marketing campaigns and donations.” By contrast, climate initiatives are more often operational or innovation based. Biodiversity efforts appear less embedded in firms’ core processes. 

Reputation Drives Action 

To understand what motivates firms, the authors link initiatives to biodiversity footprint, biodiversity dependency, and environmental controversies. 

Firms with larger biodiversity footprints are more likely to undertake initiatives, especially capacity-building actions such as adopting standards. However, footprint does not significantly increase the number of initiatives undertaken. 

Environmental controversies play a larger role. Firms experiencing controversies implement, on average, one additional biodiversity initiative. 

At the same time, biodiversity dependency shows no systematic relationship with initiative “suggesting that corporate biodiversity action is driven primarily by reputational concerns rather than reliance on ecosystem services,” as the paper states. 

The pattern points to external pressure, rather than operational reliance on nature, as the main driver of corporate biodiversity engagement. 

No Pricing—Until Policy Bites 

The next question: do markets value biodiversity initiatives? 

In standard panel regressions of monthly stock returns, biodiversity initiatives are not significantly related to returns. The result holds even after the Kunming Declaration, a major international biodiversity agreement. The picture however changes when enforceable regulation enters. 

The authors exploit the staggered introduction of biodiversity-related national taxes and fees across countries. Using a stacked difference-in-differences design, they show that firms with more biodiversity initiatives experience higher stock returns following the introduction of such fiscal instruments. 

Importantly, the effects are concentrated in innovation and capacity-building initiatives. Community engagement initiatives show no meaningful return effects. The evidence points to short-term repricing when regulation increases the salience and economic consequences of biodiversity risk.

What It Means for Decision-Makers 

For firms, the findings suggest that symbolic biodiversity actions are common but not financially rewarded. Forward-looking innovation and capacity-building initiatives may create value when regulation tightens. 

For investors, biodiversity risk does not appear fully priced in normal times. Regulatory changes can trigger adjustments. 

For policymakers, awareness alone may not move markets. Enforceable fiscal instruments, taxes and fees, appear more effective in making biodiversity financially relevant. 

In short, biodiversity becomes material to markets when regulation makes it economically consequential.
