FINANCE FLOWS: MARKET MECHANISMS
Biodiversity Credits
Trading systems for measurable biodiversity outcomes.
The transition from compliance requirements to voluntary nature-positive markets.
In 30 Seconds
Biodiversity credits connect those who impact nature with those who restore it:
- 1 credit= a measurable unit of biodiversity gain (habitat, species, ecosystem function)
- Market SizeProjected $37.55 billion by 2032 (26.1% CAGR from $5.67B in 2024)
- TNFD Momentum500+ organisations globally, 70+ in the UK have adopted TNFD
Key difference from carbon: Carbon is fungible (1 tonne = 1 tonne anywhere). Biodiversity is location-specific. A hectare of restored wetland in Norfolk has different value than one in the Amazon. This makes standardization harder but markets are emerging rapidly.
Where This Fits
Biodiversity credits are a finance flow mechanism that enables ecosystem services to generate revenue:
Physical Service
Habitat restoration, species protection, ecosystem improvement
Financial Product
Tradeable credits (verified biodiversity units)
Unlike carbon markets (which price a single outcome), biodiversity markets price complex ecosystem outcomes that are inherently location-specific.
The TNFD Inflection Point
Nature-related financial disclosure is accelerating corporate demand for biodiversity action
Why This Matters for Markets
TNFD creates a disclosure obligation that requires companies to understand their nature dependencies and impacts. This drives demand for biodiversity data, risk assessments, and ultimately action - including credit purchases to demonstrate nature-positive progress. The LEAP framework (Locate, Evaluate, Assess, Prepare) provides the methodology that connects disclosure to biodiversity credit demand.

UK Biodiversity Net Gain (BNG)
The world's first mandatory biodiversity credit market
Pre-Development Assessment
Baseline biodiversity measured using Defra Metric 4.0 - habitat types, condition, strategic significance
Design for Mitigation
Developer aims to achieve 10%+ net gain on-site through habitat creation or enhancement
Off-Site Units (if needed)
If on-site gain insufficient, purchase units from registered habitat banks or off-site providers
Statutory Credits (last resort)
Natural England statutory credits at premium price if no market units available
30-Year Management
Habitat maintained for minimum 30 years with monitoring and reporting requirements
Area Units
Measured in hectares for most habitat types
e.g., Woodland, grassland, heathland
Hedgerow Units
Measured in kilometres for linear features
e.g., Native hedgerows, tree lines
Watercourse Units
Measured in kilometres for water features
e.g., Rivers, streams, ditches
Market Challenges
Early BNG implementation has faced challenges: lack of registered habitat banks in some areas, Local Nature Recovery Strategy delays, and uncertainty around statutory credit pricing. The government has committed to reviewing the framework, but demand remains strong as development continues and developers adjust to requirements.

The Measurement Challenge
Unlike carbon, biodiversity lacks a universal metric. This is both the challenge and the opportunity.
Why Standardization Is Hard
- 1.Location-specific: A wetland in Norfolk ≠ a wetland in Amazon
- 2.Multi-dimensional: Species, habitat, ecosystem function, connectivity
- 3.Time-lag: Biodiversity outcomes take years to materialize
- 4.Baseline disputes: What would have happened anyway?
How the Market Is Responding
- 1.Proxy metrics: Habitat condition, species richness, ecosystem function
- 2.Technology: eDNA, remote sensing, AI-powered monitoring
- 3.Stacking: Combine with carbon credits for bundled value
- 4.Local standards: UK BNG, Australia's biodiversity offsets
The Opportunity
The measurement challenge creates opportunity for differentiation. Projects with robust MRV, credible baselines, and transparent monitoring command premiums. Early movers who invest in measurement infrastructure will be better positioned as markets mature and standards converge.
UK Policy Landscape
The UK has committed significant resources to nature recovery, creating the policy foundation for biodiversity markets.
Environmental Improvement Plan
Targets to halt species decline by 2030, reverse by 2042
Nature Recovery Fund
£2.7 billion annual commitment to nature recovery
Local Nature Recovery Strategies
All areas of England to have LNRSs by 2025
BNG Mandatory Requirement
10% net gain for all major developments
Green Finance Strategy
Making the UK a global hub for green finance
Nature Markets Framework
Government commitment to scaling high-integrity markets
The Investment Gap
Defra estimates the UK needs £44-97 billion of private investment for nature recovery over the next decade. Current flows are a fraction of this. Biodiversity credits are part of the solution, but will need to scale significantly alongside other mechanisms (PES, green bonds, blended finance) to close the gap.
Investment Readiness for Biodiversity Projects
Most biodiversity projects face the same challenge: they're evaluated against mature-market criteria when they're still early-stage.
The Blended Finance Opportunity
Biodiversity projects typically need 5-10 years before generating reliable credit revenue. Blended finance structures - using catalytic capital to de-risk early stages - are essential for moving projects from Stage 1-2 to Stage 3-4 where commercial investment becomes viable. See our Sustainable Finance Guide for more on the Capital Continuum framework.
Carbon vs Biodiversity Credits
| Aspect | Carbon Credits | Biodiversity Credits |
|---|---|---|
| Unit | 1 tonne CO2e | Varies (habitat units, species uplift) |
| Fungibility | High (1 tonne = 1 tonne anywhere) | Low (location-specific) |
| Standardization | Mature (Verra, Gold Standard, CCP) | Emerging (multiple approaches) |
| Market size | $0.5-4B voluntary, $113B compliance | $5.67B (2024), projected $37.55B (2032) |
| Price range | $2-1,000+/tonne | Highly variable by location/type |
| Verification | Well-established MRV | Developing (eDNA, remote sensing) |
Stacking: The Best of Both
Many projects can generate both carbon and biodiversity credits. Buyers increasingly seek “stacked” credits that deliver multiple benefits from a single intervention - forest restoration that sequesters carbon AND protects species. This bundling commands premiums and demonstrates genuine nature-positive impact.
Market Outlook: 2026 and Beyond
TNFD Becoming Mandatory
Moving from voluntary adoption to regulatory requirement in key markets. Disclosure drives demand for action.
EU Nature Credits Framework
Roadmap targeting operational framework by 2026, creating EU-wide voluntary market infrastructure.
Global Biodiversity Framework
CBD GBF commitments driving national biodiversity strategies and finance mobilization.
Technology Acceleration
eDNA, satellite monitoring, and AI enabling faster, cheaper biodiversity measurement.
BNG Market Maturation
UK market moving past early implementation challenges toward scale and liquidity.
Carbon-Nature Convergence
Buyers increasingly seeking bundled carbon+biodiversity credits for credible nature-positive claims.
The Bottom Line
Biodiversity credits are where carbon credits were 15-20 years ago: emerging, fragmented, but accelerating rapidly. The combination of regulatory pressure (BNG, TNFD), corporate commitments (SBTN, nature-positive pledges), and improved measurement technology is creating the conditions for market takeoff. Early movers who invest in understanding this space will be better positioned as it scales.
