TNFD for Asset Managers and Asset Owners: Portfolio Hotspots, Engagement and Disclosure

Figure 1. Show the path from portfolio map to stewardship and disclosure.

Portfolio heatmaps are useful because managers may hold thousands of issuers. They are easy to overinterpret. A sector rating does not show the investee’s business mix, sites or controls. A location match does not show whether the holding creates the pressure, depends on the ecosystem or faces a financial consequence. The analyst must move from potential exposure to investee-specific evidence and a decision use.

TNFD FI guidance is intended at entity level, not at financial-product level. Product data is still useful: funds and mandates are the operating layers through which research, stewardship and risk management occur. The entity-level disclosure explains the reporting entity and portfolio universe, while product-level information can support breakdowns. Product marketing claims require separate controls.

Reconcile holdings and the exposure denominator at the reporting date.

Define asset classes, public/private status, direct/indirect exposure, derivatives and cash.

Map issuers to sectors and activities; document conglomerate treatment.

Separate headquarters from operating locations and preserve location confidence.

Record product, mandate and legal-entity ownership to prevent double counting.

Sector screening identifies portfolios and issuers with potential material dependencies or impact drivers. Location screening identifies companies with assets or activities in sensitive locations. Exact site coverage is often incomplete for public markets. A first-year process may combine reported locations, project data and proxies. The manager should report the proportion of exposure with precise, approximate and missing locations and use the gaps to prioritise engagement.

FI.C0.0 and FI.C0.1 support disclosure of sector and sensitive-location exposure. For asset managers and owners they can be expressed as an amount or percentage of invested or owned assets. They are initial exposure indicators, not a conclusion that every included asset has material nature risk or negative impact.

Generic biodiversity questionnaires create fatigue. Questions should reflect the activity, geography and pathway. A food company may be asked about commodity origin, water-stressed sourcing and conversion controls; a utility about catchment dependency, abstraction and restoration; a mining company about concession polygons, critical habitat, closure liabilities and community rights.

Research. Include nature interfaces, management quality, controversies, capex and financial transmission.

Valuation and risk. Use governed assumptions; do not convert screening scores directly into valuation.

Portfolio construction. Consider concentration, mandate, liquidity, diversification and client objectives.

Stewardship. Link engagement, voting and escalation to defined expectations and outcomes.

Products. Keep product objectives, exclusions, portfolio data and marketing claims consistent.

Manager operations. Address the entity’s own governance, systems, capability and service providers.

Portfolio aggregation needs a denominator and rules: market value, committed capital, invested capital or another measure; multi-activity issuers; look-through vehicles; derivatives; and double counting across products. Breakdowns by sector, geography, biome, asset class, product, public/private, location coverage and engagement status are often more useful than one composite score. TNFD’s 2025 portfolio discussion paper explores financed impact-driver and response metrics but is not a final mandatory metric standard.

A multi-asset manager begins with public equity and corporate debt, representing 68% of AUM. Screening identifies food, utilities, mining and chemicals as hotspots. Location coverage is 55% by market value and strongest in utilities and mining. The manager selects 45 issuers for engagement, sets data and management milestones, and integrates unresolved high-priority issues into research and voting. Private infrastructure is assessed separately because asset polygons and site evidence are stronger. The entity report explains coverage, while selected products publish additional metrics under their own controlled bases.

Counting the same holding across funds. Entity aggregation needs look-through and double-counting rules.

Treating a product scope as the manager scope. Entity and product reporting layers differ.

Engaging without milestones. Activity is not evidence of outcome or effective stewardship.

Using headquarters as location evidence. This can misstate sensitive-location exposure.

Reporting one composite score. It may hide sector, geography, asset-class and data-quality differences.

Presenting discussion-paper methods as core requirements. Experimental metrics need visible status and limitations.
