Climate and Nature Risk Assessment
Nature and biodiversity
Nature risk extends beyond climate to biodiversity loss, water stress, land degradation, and ecosystem services. The TNFD framework (Taskforce on Nature-related Financial Disclosures) mirrors TCFD's four pillars (Governance, Strategy, Risk Management, Metrics and Targets) and adds the LEAP approach: Locate your interface with nature, Evaluate dependencies and impacts, Assess risks and opportunities, Prepare to respond and report.
Dependencies vs impacts
Companies depend on ecosystem services (water, pollination, raw materials) and impact nature (pollution, land use). Both create financial risk: dependency risk (supply disruption) and impact risk (regulatory, reputational, litigation). Traps: treating nature risk as purely reputational; confusing dependencies with impacts.
Measurement
Tools include encore (dependencies/impacts by sector), biodiversity metrics (e.g. Mean Species Abundance), water footprinting, and geospatial mapping of assets against sensitive ecosystems. Double materiality applies here too.
Worked example
A food company sources cocoa from a deforestation-risk region. Dependency: stable pollination and rainfall. Impact: land conversion. Risk: supply disruption (physical), EU deforestation regulation (transition/legal). LEAP locates the asset, evaluates both dimensions, assesses the two risk types, and prepares mitigation.
Traps
- Assuming climate risk covers nature risk.
- Forgetting that nature risk is location-specific.
- Ignoring that dependencies are financial exposures, not just ethical concerns.
Transition Planning and Carbon Reporting
Transition plans
A credible transition plan sets out how an entity will move to a low-carbon, climate-resilient model. Common components: baseline emissions, targets (often SBTi-aligned), decarbonisation levers, capital expenditure alignment, governance, and disclosure. Frameworks include TCFD/ISSB, the Glasgow Financial Alliance for Net Zero (GFANZ) guidance, and the UK Transition Plan Taskforce. Traps: plans without interim targets, capex, or accountability are 'plan-washing'.
Carbon reporting
GHG Protocol defines the scopes: Scope 1 direct emissions, Scope 2 purchased energy (location- vs market-based), Scope 3 value-chain (15 categories). Reporting standards include ISSB IFRS S1/S2, GRI, CDP, and the CSRD/ESRS in the EU. The GHG Protocol Corporate Standard and Scope 3 Standard underpin most regimes. Assurance (limited vs reasonable) raises credibility.
Worked example
A firm buys renewable electricity via a PPA. Under the market-based Scope 2 method it may report near-zero; under location-based it reports the grid average. Both may be disclosed - a classic exam trap is assuming only one method applies.
Traps
- Confusing Scope 2 methods (location vs market).
- Forgetting that Scope 3 has 15 categories.
- Treating a target as a transition plan - a plan needs levers, capex, and governance.
- Ignoring assurance and data quality.
