Biodiversity and Nature Risk: ESG Obligations Under TNFD for Australian Businesses

Published: March 2026 | Updated: March 2026

Australia is one of the world’s megadiverse countries—yet faces one of the highest extinction rates. Over 1,700 species are threatened with extinction; land clearing, invasive species, climate change and pollution drive biodiversity decline. For Australian businesses, biodiversity risk is increasingly material: supply chain dependencies on natural capital (agriculture, fishing, forestry), regulatory exposure (EPBC Act), investor pressure (Taskforce on Nature-related Financial Disclosures), and physical risks from ecosystem collapse.

This article guides Australian organisations through biodiversity risk assessment and management for environmental ESG strategy. We cover Australia’s biodiversity crisis, the TNFD framework, EPBC Act compliance, and integration with your broader ESG strategy. Whether you’re directly extractive (mining, agriculture) or downstream of natural capital dependencies, this guide helps you assess and manage nature risk.

Australia’s Biodiversity Crisis

The Scale of the Crisis

Australia’s biodiversity is under extreme pressure:

  • Land clearing: 1.7 million hectares cleared 2000–2017; accelerating (2021–2022: 380,000 hectares)
  • Habitat loss: Primary driver of extinction; 34% of threatened mammal species; 800+ plant species threatened
  • Climate change: Range shifts, breeding cycle disruption, heat stress; synergistic with habitat loss
  • Invasive species: Feral cats, rabbits, cane toads disrupt ecosystems; costly to control
  • Pollution: Microplastics, PFAS, agricultural runoff degrade waterways and marine ecosystems
  • Overexploitation: Fisheries overexploited; native species harvesting (timber, wildlife) exceeds sustainable levels

Australia’s extinction rate is 5–10 times global average. Without intervention, ecosystem services (pollination, water regulation, carbon sequestration) will degrade, creating systemic business risk.

Australia’s Biodiversity Policy Framework

Environment Protection and Biodiversity Conservation Act (EPBC Act): Primary federal biodiversity law; requires assessment of projects affecting matters of national environmental significance (MNES) including threatened species, wetlands, ramsar sites. Assessments can delay or block projects; criminal penalties for breaches.

Threatened Species Legislation: State-based laws protect threatened species; vary by state (NSW Biodiversity Conservation Act, Victorian Biodiversity Conservation Strategy, WA Biodiversity Conservation Act). Understanding your state obligations is essential.

Biodiversity Offsets: EPBC Act allows offset of biodiversity impacts (e.g., clearing habitat for mining, offset by protecting equivalent habitat elsewhere). Offset quality varies; poorly designed offsets create greenwashing risk.

The Taskforce on Nature-Related Financial Disclosures (TNFD)

TNFD Framework and Recommendations

TNFD (analogous to TCFD for climate) provides a framework for assessing and disclosing nature-related financial risk. TNFD recommendations include:

  • Governance: Board and executive accountability for nature risk; nature strategy in corporate strategy
  • Strategy: Assess nature dependency and impacts across value chain; scenario analysis for nature risk
  • Risk Management: Identify and mitigate nature-related risks (habitat loss, species extinction, resource scarcity)
  • Metrics and Targets: Disclose nature-related KPIs; set biodiversity targets aligned to science (e.g., no net loss, net positive by 2030)

TNFD is not yet mandatory in Australia but is increasingly expected by investors, particularly superannuation funds and ESG-focused allocators. Early adoption signals ESG maturity.

TNFD vs. Climate: Key Differences

Nature risk differs from climate risk: it’s spatially explicit (impacts vary by location), tipping points are local (ecosystem collapse in one region may have global supply chain impacts), and solution involve nature-based recovery (not just decarbonisation). TNFD emphasises dependency and impact assessment more than climate does.

Nature Dependency and Impact Assessment

Step 1: Map Your Nature Dependencies

Identify where your organisation depends on natural capital:

  • Direct operations: Land use, water, soil quality (agriculture, mining, energy, timber)
  • Supply chain: Agricultural inputs, seafood, timber, minerals (all dependent on healthy ecosystems)
  • Indirect: Pollination (crops), water regulation (watersheds), climate regulation (forests)

Organisations in agriculture, fishing, timber, mining, energy, food and beverage have direct nature dependencies. Service and retail organisations have less direct but significant supply chain dependencies (e.g., retail depends on agricultural supply chains).

Step 2: Assess Nature Impacts

Identify where your organisation impacts biodiversity:

  • Direct land use: Habitat loss from mining, agriculture, development
  • Pollution: Emissions, chemical runoff, plastic, PFAS affecting ecosystems
  • Resource extraction: Overharvesting of fish, timber, water affecting species and populations
  • Supply chain: Deforestation (palm oil, beef, soy), overfishing, pesticide use

For each impact, identify affected species, ecosystems, and timeline. Prioritise material impacts; these drive TNFD disclosure and ESG strategy.

Step 3: Scenario Analysis

Model scenarios reflecting nature risk:

  • No-action scenario: Biodiversity continues declining; ecosystem services degrade; supply chain becomes unreliable
  • Regulated scenario: Stricter EPBC enforcement, extended species protections, land-use restrictions; operations may be constrained
  • Climate-stress scenario: Climate change exacerbates habitat loss; species range shifts; pollinator decline disrupts agriculture
  • Nature-positive scenario: Organisation actively restores biodiversity; supply chains transition to regenerative practices; competitive advantage

Scenario analysis quantifies financial impact of nature risk; builds case for investment in nature-positive strategy.

Biodiversity Strategy and Action

Avoid, Reduce, Restore, Offset Hierarchy

Align to conservation hierarchy:

  • Avoid: Don’t operate in high-conservation areas; prevent habitat loss. Most impactful but constraining
  • Reduce: Minimise impacts in operations; use lower-impact practices
  • Restore: Active habitat restoration on-site or nearby; creates positive biodiversity impact
  • Offset: Last resort; offset losses elsewhere (EPBC offsets, conservation payments). Quality varies; greenwashing risk

Best ESG practice prioritises avoid and reduce ahead of offsets.

Sector-Specific Actions

Agriculture: Transition to regenerative practices; restore riparian buffers; reduce pesticide/fertiliser use; preserve habitat corridors.

Mining/Extraction: Minimise habitat clearing; plan pre-mining biodiversity baseline and post-mining rehabilitation; engage traditional owners in land management.

Retail/Food & Beverage: Engage suppliers on sustainable agriculture, fishing, timber sourcing; support certification (FSC, MSC, RSPO); transition supply chain to regenerative inputs.

Finance/Services: Divest from biodiversity-destructive practices; invest in nature-positive businesses; integrate nature risk into investment decisions.

Targets and Governance

Set biodiversity targets (e.g., “net positive biodiversity by 2030,” “100% sustainable sourcing by 2025”). Board oversight signals commitment. Link executive compensation to biodiversity KPIs (habitat restored, species protected, sustainable sourcing %).

Biodiversity Offsets: Quality and Credibility

Under EPBC Act and state laws, biodiversity impacts can be offset. However, offset quality is highly variable; poor offsets are greenwashing.

Offset Quality Criteria

  • Like-for-like: Offset habitat type matches impact habitat; species protected match species impacted
  • Permanence: Offset protection is permanent or long-term (covenants, law); not temporary projects
  • Additionality: Offset habitat wouldn’t be protected anyway; offset directly prevents future loss
  • Verified: Independent assessment confirms habitat quality and protection; not self-reported
  • Risk reduction: Monitoring plan ensures offset succeeds; contingency if offset fails

High-quality offsets employ conservation covenants (legal protection), species reintroduction programs, or land acquisition. These are effective but expensive (often AUD $10K–$50K per hectare). Be cautious of cheap offsets; they often have low additionality or permanence.

Frequently Asked Questions

Is biodiversity material to non-extractive businesses?

Yes, increasingly. Supply chain biodiversity risk (agriculture, fishing, timber, minerals) affects all sectors. Pollinator decline threatens food supply; forest loss disrupts water and carbon cycles; ocean ecosystem collapse threatens fisheries. For retail, food and beverage, finance and logistics, supply chain biodiversity is material. TNFD disclosure is expanding expectation beyond extractive industries.

How do we assess biodiversity materiality?

Map nature dependencies and impacts using TNFD guidance. If your supply chain includes agriculture, fishing, timber or minerals from biodiverse regions, biodiversity is material. If your operations are in high-conservation areas (wetlands, endangered species habitat), biodiversity risk is material. Quantify financial impact: supply chain cost if sourcing becomes regulated, remediation cost if operations impact listed species.

Are biodiversity offsets credible for ESG claims?

Only if high-quality. TNFD and ESG consensus prioritises avoid and reduce; offsets are last resort. If offsets are used, ensure they meet quality criteria (like-for-like, permanent, additive, verified). Poor-quality offsets are greenwashing and create regulatory and reputational risk. Be transparent: disclose offset type, location, risk and monitoring plan.

How do we engage indigenous communities on biodiversity?

Indigenous Australians manage ~30% of land; many are custodians of biodiverse areas. Partnership with indigenous communities for land management, species recovery and habitat restoration is increasingly essential for ESG credibility and regulatory compliance (EPBC Act requires indigenous engagement). Co-design projects; respect indigenous knowledge; ensure benefit-sharing.

Is TNFD disclosure mandatory in Australia?

Not yet, but AASB is developing Australian nature-related disclosure standards expected 2025–2026. Early TNFD adoption is recommended for listed companies and those with investor ESG pressure. TNFD disclosure demonstrates ESG maturity and reduces regulatory risk.

How do we prevent greenwashing in biodiversity claims?

Be specific: “We protect/restore X hectares of habitat for Y species” with location, timeline and monitoring. Avoid vague claims (“we support biodiversity”). Document baseline (biodiversity before action), action taken, and outcome. Third-party verification (environmental audit, certification) strengthens credibility. Transparent offset methodology (if used) avoids greenwashing risk.
