Nature-related disclosures UK: TNFD framework and emerging requirements

Nature-related disclosures in the UK context

Nature-related disclosures address the financial risks and opportunities arising from biodiversity loss, ecosystem degradation, and natural capital depletion 58. Following the success of climate-related financial disclosures, the approach extends systematic risk assessment to nature and biodiversity impacts affecting business operations.

The UK government has committed to considering mandatory nature-related disclosure as part of its environmental policy framework, building on the 25 Year Environment Plan and international commitments under the Convention on Biological Diversity 59. This reflects recognition that nature risks create systemic financial system vulnerabilities requiring disclosure and management.

Current UK implementation operates through voluntary adoption of the Taskforce on Nature-related Financial Disclosures (TNFD) framework, with growing uptake among major UK companies and financial institutions 58. Early adopters gain experience ahead of potential mandatory requirements while demonstrating leadership on emerging environmental risks.

TNFD framework structure and requirements

The TNFD framework published in September 2023 provides the global standard for nature-related financial disclosures, using the same four-pillar structure as TCFD (governance, strategy, risk management, metrics and targets) adapted for nature and biodiversity risks 58. This creates familiar disclosure architecture for companies already implementing climate disclosures.

TNFD introduces the LEAP assessment process (Locate, Evaluate, Assess, Prepare) for systematic identification and analysis of nature-related risks and opportunities 58. Companies locate their interface with nature, evaluate dependencies and impacts, assess risks and opportunities, and prepare responses including disclosure and action.

Nature-related risks include physical risks (ecosystem disruption affecting operations), transition risks (policy responses to biodiversity loss), and systemic risks (ecosystem collapse affecting broader economic systems) 58. These risk categories parallel climate risk frameworks while addressing nature-specific transmission mechanisms.

Metrics and targets cover both impact metrics (how company activities affect nature) and dependency metrics (how company operations rely on ecosystem services) 58. This dual approach reflects the bidirectional relationship between business and nature, distinguishing nature disclosures from unidirectional climate impact assessment.

UK regulatory landscape for nature disclosures

The UK government has indicated consideration of mandatory nature-related disclosure requirements as part of broader environmental policy integration, with potential implementation through sustainability reporting frameworks or sector-specific regulations 59. This aligns with international momentum toward nature disclosure mandates.

HM Treasury's Green Finance Strategy identifies nature-related financial risks as a priority area for financial system stability, suggesting potential financial sector requirements ahead of broader corporate mandates 60. The Bank of England has begun research on nature-related risks for financial stability assessment.

International coordination through the G20 and NGFS (Network for Greening the Financial System) creates pressure for UK alignment with global nature disclosure standards, particularly as EU and other jurisdictions develop mandatory requirements 59. This external pressure reinforces domestic policy development.

UK-specific nature risks include coastal ecosystem vulnerability affecting infrastructure and operations, water stress in southeastern England affecting operational efficiency, and agricultural system changes affecting food and agriculture sectors 59. These domestic risk factors drive UK policy interest in nature disclosures.

Nature risk materiality assessment

Nature risk materiality assessment requires evaluation of how biodiversity and ecosystem factors create financial risks or opportunities affecting enterprise value 58. This assessment determines which nature-related factors meet disclosure thresholds under UK sustainability reporting frameworks.

Physical dependency assessment examines how business operations rely on ecosystem services including water provision, climate regulation, pollination, and raw materials supply 58. Disruption to these services creates operational risks affecting production capacity and cost structures.

Impact assessment evaluates how company activities affect biodiversity and ecosystems, creating risks through regulatory responses, stakeholder pressure, or license-to-operate challenges 58. These impacts translate to financial effects through regulatory, reputational, and market transmission mechanisms.

Geographic analysis identifies locations where nature dependencies and impacts create concentrated risks, using tools like TNFD's data hub and geographic information systems to assess ecosystem health and regulatory pressures 58. Location-specific analysis enables targeted risk management strategies.

Integration with UK SRS requirements

Nature-related disclosures integrate with UK SRS through materiality assessment under UK SRS S1 general requirements, with financially material nature risks requiring disclosure alongside climate and other sustainability factors 4. This creates pathway for nature disclosure without separate regulatory framework.

Climate and nature risk interactions require integrated assessment, as climate change accelerates biodiversity loss while nature-based solutions contribute to climate adaptation and mitigation 4. Companies should coordinate climate and nature risk analysis to capture these interconnections.

Governance integration ensures board oversight and management processes address nature risks alongside climate and other sustainability risks, using common governance frameworks and accountability structures 4. This integrated approach reduces governance complexity while ensuring comprehensive risk coverage.

Scenario analysis coordination aligns nature risk scenarios with climate scenarios where applicable, using consistent assumptions about future environmental and policy conditions 58. This integration enhances analytical coherence while reducing implementation burden.

Nature disclosure implementation approach

Implementation begins with TNFD LEAP assessment to identify material nature dependencies and impacts, focusing initially on high-risk locations and business activities with clear nature interfaces 58. This targeted approach manages implementation complexity while building analytical capability.

Data collection prioritizes readily available information including location data, supply chain mapping, water consumption metrics, and land use footprints before progressing to specialized biodiversity data 58. This staged approach enables early progress while building toward comprehensive assessment.

Stakeholder engagement includes conservation organizations, local communities, and supply chain partners to understand nature impacts and dependencies from multiple perspectives 58. This engagement provides practical insights not captured in desktop analysis.

• Conduct TNFD LEAP assessment focusing on high-risk locations and activities
• Map business dependencies on ecosystem services and impacts on biodiversity
• Assess financial materiality of identified nature risks and opportunities
• Integrate nature risk assessment with existing climate and sustainability risk frameworks
• Develop nature-related metrics and targets aligned with business strategy
• Establish governance processes for nature risk oversight and management

Performance monitoring develops metrics covering both impact reduction (biodiversity footprint, ecosystem restoration) and dependency management (water efficiency, supply chain resilience) 58. These metrics enable progress tracking while supporting strategic decision-making about nature risk management.
