The Methodology

LEAP in one paragraph.

The LEAP approach is the structured, scopable, repeatable methodology that the TNFD recommends for moving from a blank page to a credible nature disclosure. Each phase has clear inputs, deliverables, and decision points — so a sustainability lead, a risk officer, and a CFO can each see what is being produced, when, and how it informs strategy. LEAP is sector-agnostic: the same four steps work for a global food company, a regional miner, a real-estate REIT, or a domestic bank.

The point of LEAP is not academic completeness — it is to produce actionable outputs at every step: a priority-location list, a dependency-impact register, a risk & opportunity matrix, and a disclosure draft. Each phase answers a specific board-level question.

The Four Phases

From scope to disclosure in four steps.

Each phase has a tight scope, a primary data source set, and a single deliverable. The order matters — LEAP is sequential, not parallel.

L

Locate — Interface with Nature

Where does the business meet nature?

Map direct operations, value-chain assets and their geographic footprint against ecologically sensitive areas (Key Biodiversity Areas, Ramsar wetlands, IUCN protected areas, water-stressed catchments). Output is a priority-location list — the 10–30 sites that drive material nature exposure. Built from ENCORE sector dependencies, IBAT site overlays, WWF Water Risk Filter, Global Forest Watch, plus internal asset registers.

E

Evaluate — Dependencies and Impacts

What does nature give us, and what do we do to it?

For each priority location, identify dependencies (pollination, freshwater, soil fertility, climate regulation, flood protection) and impacts (land-use change, freshwater withdrawals, GHG, pollutants, waste, invasive species introduction). Quantify where data permits, qualify where it does not. Output is a structured dependency-impact register tied to specific assets.

A

Assess — Risks and Opportunities

What does this mean financially?

Translate dependencies and impacts into physical risks (water scarcity disrupting production), transition risks (regulation, litigation, market shifts) and systemic risks (ecosystem collapse, supply-chain cascades). Identify nature-positive opportunities — cost reduction, resilience, new revenue. Output is a risk & opportunity matrix scoring exposure, time horizon, and action priority.

P

Prepare — Report, Respond and Disclose

How do we act and tell the story?

Produce two outputs: (1) internal response actions — policy changes, target setting, project investments, supply-chain interventions; and (2) external disclosure aligned with TNFD’s 14 recommendations, plus any overlapping requirements (CSRD ESRS E4, BRSR, CDP). The disclosure should be explicit about data gaps, proxy assumptions, and methodological boundaries.

Common Pitfalls

Five mistakes the first LEAP cycle makes.

Climate Decode has run LEAP cycles across food, mining, finance and infrastructure clients. Five failure modes recur on the first attempt — plan around them.

01
Boil the ocean at Locate

Trying to map every site in year one. Rank by materiality — revenue, hectares, water draw — and stop at the top 10–30.

02
Confuse dependencies with impacts

They are different categories with different data sources. ENCORE for dependencies, site-level surveys and IBAT for impacts.

03
Ignore upstream

For most consumer companies, >90% of nature impact is in the supply chain. A LEAP that stops at the factory gate fails the materiality test.

04
Treat Assess as a checkbox

Risk scoring without scenario logic produces a flat list. Use TNFD’s scenario archetypes (Ahead Together, Sand in the Wheels, etc.) to stress-test.

05
Write the disclosure last

The disclosure structure should drive Phase 1 scoping. Start with the 14 recommendations and work backwards into what data each one requires.

How Climate Decode Runs a LEAP Engagement

A typical 12–20 week delivery.

We scope to your sector and footprint, run the data work, and hand back a board-ready package — not a thousand-page slide deck.

Weeks 1–4
Scope & Locate

Sector-dependency screening, asset and value-chain mapping, priority-location shortlist, kick-off workshop with the disclosure team.

Weeks 5–12
Evaluate & Assess

Dependency-impact register, scenario stress-tests using TNFD archetypes, financial materiality view, draft risk & opportunity matrix shared with finance and risk.

Weeks 13–20
Prepare & Disclose

Disclosure draft against all 14 TNFD recommendations, ESRS E4 / BRSR cross-mapping, board-pack summary, and a phased response plan with named owners.
