Nature-related risk, assessed with rigour and disclosed with confidence
Nature-related dependencies and impacts are moving onto the agendas of supervisors, investors and standard-setters. We help banks, insurers and investors run TNFD-aligned assessments, prioritise what is material, and build the foundations for nature to inform financial decisions.
The expectations are clear. The methods are still maturing.
TNFD, ESRS E4 and supervisors expect nature-related assessment, yet biodiversity data is fragmented and location-specific, and there is no established method for translating nature findings into credit, underwriting or valuation terms. Institutions need assessments that are honest about these limits and useful despite them.
Rigorous assessment, honest about what is possible today
There is no accepted method today for a portfolio-wide nature-adjusted PD. Ledger quantifies only where a channel can be modelled with counterparty data, typically water availability, regulation-driven market access and commodity yield shocks, and uses structured expert overlays elsewhere.
Engagement formats
Nature Materiality Scan
6 weeks. ENCORE-based screening, location overlay where data allows, priority sectors and transmission channels agreed, and a FINMA 2028 readiness view.
TNFD Assessment & Disclosure
Full LEAP execution and disclosure preparation, aligned with TNFD, the ISSB Exposure Draft and ESRS E4 where in scope.
Ledger Sector Deep-Dive
8–10 weeks. One or two priority sectors carried into credit or underwriting: 15–25 counterparties per sector, one channel stressed against their financials, then credit guidance, watchlist triggers and an engagement plan.
Location-based Screening
Screening of priority assets against biodiversity sensitivity and water stress, using established datasets with a geospatial partner where needed.
Outcomes clients can point to
- A defensible nature baseline: located, evaluated and prioritised
- TNFD- and ESRS-aligned disclosures grounded in analysis rather than boilerplate
- Clarity on where nature is most likely to become financially material
- A credible starting point for integrating nature into financial decisions as methods mature
How we approach nature & biodiversity
LEAP-to-Ledger
TNFD tells you what to assess. Ledger tells you where it lands in your processes. We run the TNFD LEAP approach, then move each material finding into the credit, underwriting and investment processes you already operate, ahead of FINMA’s 2028 nature scope and the ISSB’s nature proposals.
- LLocate
Priority sectors confirmed with exposure attached; counterparty or asset locations geo-referenced, even approximately; interfaces with sensitive locations flagged.
- EEvaluate
Dependencies on ecosystem services and impact drivers identified per priority sector, including the upstream value chain where it dominates the risk.
- AAssess
A transmission channel written for each material issue, at least one plausible stress per priority sector, and a materiality judgement recorded with its rationale.
- PPrepare
A named owner for nature-related risk in the risk function, and a disclosure approach mapped to TNFD, the ISSB proposals and ESRS E4.
- → LedgerPrice · Provision · Position
Each material finding routed to a named process and owner: terms and pricing where a quantified channel supports it; early-warning and provisioning governance; and portfolio shape and client strategy.
A finding that produces no Ledger entry is context, not yet risk management.
