Biodiversity Investing: The Emerging Asset Class Worth $37 Billion by 2032
By Dirk Röthig, CEO, VERDANTIS Impact Capital | March 2026
For most of capital market history, biodiversity was a conservation concern — important, perhaps urgent, but not investable. That framework is now obsolete. A convergence of regulatory mandates, measurement innovation, and market infrastructure has transformed biodiversity from an externality into an asset class. By 2032, the global biodiversity credit market alone is projected to reach $37 billion (Morgan Stanley, 2023). The institutional investors who arrive early will define the market structure for decades.
This article examines the architecture of biodiversity investing: its market size, the mechanics of biodiversity credits, the regulatory scaffolding being erected by the EU and TNFD, and how stacking biodiversity revenues with carbon creates the most compelling nature-based investment proposition of the decade.
Why Biodiversity Is Becoming Investable Now
Three forces have converged to create the biodiversity investment opportunity.
First: the crisis is now quantified. The IPBES Global Assessment (2019) documented that 1 million plant and animal species face extinction risk — the most severe species loss since the end-Cretaceous mass extinction 66 million years ago (IPBES, 2019). More precisely relevant for finance: $44 trillion of GDP, representing more than half of global economic output, depends on nature-related ecosystem services (WEF, 2020). Biodiversity loss is no longer a soft environmental risk; it is a systemic economic risk.
Second: measurement frameworks now exist. Until 2020, there was no agreed methodology for measuring corporate biodiversity impact. The Taskforce on Nature-related Financial Disclosures (TNFD) v1.0 framework (2023) and the Science-Based Targets for Nature (SBTN) initiative (2023) have changed this. Biodiversity can now be measured, attributed, and compared — a prerequisite for market formation.
Third: regulatory mandates are creating demand. The EU Nature Restoration Law (Regulation 2024/1991), the UK Biodiversity Net Gain requirement (mandatory from January 2024), and the Kunming-Montreal Global Biodiversity Framework (30x30 target by 2030) are collectively generating institutional demand for biodiversity credits that did not exist five years ago.
The Biodiversity Credit Market: Size, Mechanics, and Price Discovery
A biodiversity credit represents a verified unit of biodiversity gain — typically defined as a measurable improvement in habitat quality, species richness, or ecosystem function at a specific geographic location. Unlike carbon credits (which represent a universal unit of CO₂ equivalent), biodiversity credits are inherently local: a wetland credit in Flanders cannot substitute for a grassland credit in Bavaria, because the ecosystems, species assemblages, and regulatory contexts differ.
This locality is both the credit's scientific virtue and its principal market limitation.
Market Size Projections
- Current market (2024): Estimated at $500 million–$1 billion globally, dominated by compliance markets (UK BNG, US mitigation banking) (Ecosystem Marketplace, 2024)
- 2025–2030 trajectory: Morgan Stanley (2023) projects the market reaching $37 billion by 2032, driven primarily by EU regulatory mandates under the Nature Restoration Law and CSRD biodiversity disclosure requirements
- Long-run potential: HSBC and Nature4Climate estimate the market could reach $69 billion annually by 2050 if voluntary and compliance markets mature in parallel (Nature4Climate, 2023)
How Biodiversity Credits Are Generated
Credits are generated through conservation, restoration, or enhancement activities that demonstrably improve biodiversity outcomes relative to a baseline. Current methodologies include:
UK Biodiversity Net Gain (BNG): The UK's Environment Act (2021) mandated that all new developments achieve a 10% net gain in biodiversity, measured using the Defra Biodiversity Metric 4.0. Developers who cannot achieve BNG on-site must purchase off-site credits or statutory biodiversity credits from government. As of 2024, statutory credits are priced at £42,000 per unit for high distinctiveness habitat, creating a clear price floor (Defra, 2024).
US Conservation Banking and Mitigation Banking: Established compliance markets requiring developers impacting wetlands or endangered species habitat to purchase mitigation credits. The US mitigation banking market transacts approximately $3.8 billion annually (USACE, 2023).
Voluntary Biodiversity Credits: Newer market with less price discovery. Leading methodologies include the Terrasos Habitat Bank standard (Colombia), the Wallacea Trust methodology, and Verra's upcoming SD Vista+ biodiversity module. Prices range from $10–$150 per credit depending on methodology, location, and certification rigour (Ecosystem Marketplace, 2024).
The EU Nature Restoration Law: A Regulatory Demand Catalyst
The EU Nature Restoration Law (Regulation 2024/1991, entered into force August 2024) is the most consequential biodiversity regulation in EU history. Its key provisions:
- Member states must restore at least 20% of EU land and sea areas by 2030, rising to 90% of all ecosystems in "poor condition" by 2050
- Legally binding national restoration plans must be submitted to the Commission by 2026
- Specific targets for agricultural ecosystems: reversal of farmland bird decline, improvement of grassland butterfly index, net increase in high-diversity landscape features
- Urban ecosystem restoration: member states must achieve net gain in urban green space and urban tree canopy in all cities over 50,000 inhabitants
The implementation cost has been estimated at €154 billion over 10 years (EU Commission, 2022). The Commission acknowledges that public budgets alone cannot finance this — creating a structural gap that private biodiversity investment must fill.
This is not incremental. The Nature Restoration Law means that every EU member state must demonstrate measurable ecological improvement across specified ecosystem categories within legally binding timelines. For biodiversity investors, this translates into durable, regulation-backed demand for ecosystem restoration services.
TNFD: The Disclosure Framework Shaping Capital Flows
The Taskforce on Nature-related Financial Disclosures (TNFD), launched its v1.0 recommendations in September 2023. Built on four pillars — Governance, Strategy, Risk & Impact Management, and Metrics & Targets — TNFD mirrors the TCFD structure that has now been integrated into mandatory disclosure in the UK, EU, and major financial jurisdictions.
Key investor implications:
- LEAP approach: TNFD recommends the LEAP (Locate, Evaluate, Assess, Prepare) approach for nature-related dependency and impact analysis — a structured methodology that links corporate operations to specific ecosystem locations and services
- Sector guidance: TNFD has published sector-specific guidance for food and agriculture, metals and mining, forestry, and financial institutions — confirming that no major sector escapes nature-related risk exposure
- Regulatory integration: The EU CSRD already incorporates TNFD-aligned requirements through ESRS E4. ISSB is developing an IFRS Sustainability Standard on nature-related disclosures expected in 2026
As of March 2025, over 400 organisations managing $15+ trillion have formally adopted TNFD (TNFD, 2025). Asset owners are beginning to integrate nature-related risk into portfolio construction — creating momentum behind biodiversity-positive assets.
Stacking Carbon and Biodiversity: The Revenue Model That Changes Returns
The most financially compelling innovation in biodiversity investing is stacking — layering multiple revenue streams from the same underlying ecosystem or plantation asset.
A well-designed agroforestry project can simultaneously generate:
- Carbon removal credits under CRCF (Regulation 2024/3012) or Verra VM0047 — priced at $8–25 per tonne CO₂e
- Biodiversity credits under emerging EU or voluntary frameworks — priced at $10–150 per unit depending on methodology
- Timber or biomass revenues from sustainably managed plantations
- EU agri-environment payments (Eco-scheme payments under GAP, up to €200/ha/year in Germany)
At VERDANTIS, we structure investments that integrate all four revenue streams. Using Paulownia-based agroforestry as the core asset:
- Carbon sequestration of 33–60 tonnes CO₂e per hectare per year (Ferrara et al., 2024), generating 330–600 CRCF certificates per hectare over 10 years
- Demonstrable biodiversity improvement through elimination of monoculture, pollinator corridor establishment, and soil biota restoration — measurable under TNFD LEAP methodology
- Timber revenue after 8–10 year harvest cycle at €120–180/m³ for paulownia hardwood (European Wood Report, 2023)
- Intercropping revenues (honey, mushrooms, medicinal plants) during the tree growth phase
The stacking mechanism transforms the financial profile: what would be a marginal forestry investment at carbon-only pricing becomes a high-conviction impact asset when biodiversity co-revenues are captured and verified.
Key Risks in Biodiversity Investing
Biodiversity investing carries distinct risks that carbon markets have spent 20 years learning to manage. Investors should examine:
Additionality risk: The biodiversity improvement must be additional — it would not have occurred without the investment. This is harder to prove in biodiversity than in carbon, because ecosystems are more complex and baselines are contested.
Permanence risk: Unlike carbon, biodiversity losses are often irreversible (species extinction). Permanence periods for biodiversity credits are therefore more contested — what is the minimum commitment period? UK BNG requires 30 years.
Metric standardisation risk: No single global biodiversity metric commands universal acceptance. The EU is developing its own methodology (under the EU Biodiversity Strategy and Nature Restoration Law), but alignment with UK BNG, US mitigation banking, and voluntary frameworks remains incomplete.
Double counting risk: When biodiversity and carbon credits are stacked from the same activity, rigorous accounting must ensure the same unit of ecological improvement is not sold twice into separate markets.
These risks are manageable with robust project design, third-party verification, and appropriate legal structuring. They are not fundamentally different from the risks that carbon markets navigated in their first decade.
Investment Vehicles: How to Access the Market Today
For institutional investors seeking biodiversity exposure, entry pathways include:
Listed equities: Companies with significant biodiversity-positive activities (sustainable forestry, ecological restoration, habitat management) screened through TNFD and SBTN alignment criteria.
Private funds: Specialist nature funds (Mirova Natural Capital, Conservation Capital, Paladin Capital Group's Nature Fund) providing direct biodiversity project exposure with credit revenue.
Green bonds with biodiversity KPIs: Sustainability-linked bonds with biodiversity performance targets are a growing subset of the $600+ billion green bond market.
Direct project investment: For sophisticated investors, direct investment in BNG bank or agroforestry projects provides maximum revenue capture but requires project management capability.
Conclusion
Biodiversity investing has crossed the threshold from aspiration to asset class. The $37 billion market projection for 2032 is not speculative — it is grounded in binding regulatory mandates, established measurement frameworks, and growing institutional adoption. The EU Nature Restoration Law alone creates a structural demand for biodiversity restoration that no purely public budget can satisfy.
The combination of biodiversity credits stacked with carbon revenues and agri-environment payments creates a multi-revenue investment structure that fundamentally reframes nature-based investment economics. Investors who understand the mechanics of biodiversity credits and position accordingly in 2026 are likely to be defining the market infrastructure others will adopt over the next decade.
