Turn Your Sustainability Solution Into
a Financial Business Case.
EFR‑IVL™ converts physical climate and sustainability risks into client-specific financial business cases — helping climate, sustainability and adaptation companies demonstrate the commercial value of what they sell.
Your customer may already understand the sustainability problem. The harder question is often: what does it mean financially — and why invest now?
You bring the sustainability expertise, evidence or solution. EFR-IVL adds the financial decision layer.
From sustainability evidence to financially informed capital deployment.
Designed to help sustainability, climate-risk, adaptation and climate-tech companies make the commercial value of their solutions financially visible to customers.
Your customer already understands the problem.
The budget is often the harder conversation.
A sustainability company can usually demonstrate physical exposure, climate risk, regulatory exposure, operational vulnerability, adaptation need or a technical solution. The customer may still ask what it means for earnings, what it could cost, how much to invest, what value an intervention could protect, and what to prioritise. EFR-IVL helps bridge that conversation.
Sustainability companies know the problem. Customers still ask "what does this mean financially?"
A sustainability, climate-risk or adaptation company can usually explain the customer's exposure and what solution addresses it. What the customer often still needs is the financial case for acting now — and EFR-IVL is designed to help bridge that gap.
EFR-IVL does not guarantee an outcome. It helps create a stronger financial case, supports a more informed investment decision, and helps make the commercial value of a solution financially visible.
Built for the sustainability ecosystem.
EFR-IVL adds a financial decision layer to your existing sustainability expertise, data and solutions. It is not a replacement for what you already do.
Potential commercial uses include customer proposals, business-case development, account expansion, investment-appraisal conversations and solution positioning.
These are illustrative configurations of the same decision architecture, not independently validated production deployments for each sector.
What changes when the risk becomes a number.
"Your customer is exposed to increasing physical climate risk."
Customer: "What does that mean financially?"
Decision: Invest — Staged Programme
Illustrative example. Client-specific data and validation required — this is not a real client case and the figures are not universal; it demonstrates the type of business case EFR-IVL is designed to help construct.
The objective is not to replace the partner's solution. It is to help the customer understand the financial rationale for considering it.
Build a Customer Business Case Around Your Solution.
Configure EFR-IVL around your solution, your target customer and the decision you want the customer to make.
Give EFR-IVL three starting points — the customer problem, your solution and the decision being considered — and the architecture can be configured around the relevant financial pathways, evidence requirements, intervention economics and decision criteria. Demonstrator / illustrative — not a live production tool.
This is not "buy EFR-IVL software." It is using EFR-IVL as a financial decision layer around your existing customer proposition.
Customer + Problem + Solution + Existing Evidence
Financial Translation + Scenario Analysis + Investment Logic + Decision Readiness
Customer Business Case
Hospital / industrial company → heat exposure → operational / financial impact → adaptation solution → investment case
Industrial customer → water stress → production / cost exposure → efficiency / resilience solution → investment case
Food / agricultural customer → nature / soil / commodity exposure → COGS / supply-chain impact → intervention → investment case
Corporate customer → material sustainability issue → financial relevance → management action → investment priority
You bring the expertise. EFR-IVL adds the financial decision layer.
Result: a stronger customer business case.
EFR-IVL is designed to complement — not replace — existing sustainability, climate-risk, adaptation, reporting and climate-tech offerings.
What the customer receives.
This directly connects the commercial proposition to the EFR-IVL architecture described below.
What could the issue mean financially?
Which physical, operational or sustainability pathways drive the exposure?
What can the customer do?
How much capital may be required?
What potential value could the intervention protect?
How does the business case change under different scenarios?
How strong is the supporting evidence?
What information is still required?
Invest, stage, prioritise or defer.
The output is designed to support the customer's decision process — not to guarantee an investment outcome.
Extreme Heat — Flagship Demonstrator
A working demonstrator showing how physical-risk evidence can be translated into financial exposure, scenario analysis, adaptation economics and a structured capital decision. Heat demonstrates the architecture; it is not the architecture. For a sustainability company, v3.6 demonstrates the financial intelligence layer that can sit behind a customer-specific business case.
The figures above are the fixed, company-level case. The interactive panel below is a separate scenario slice — EV@Risk — Heat Edition, DRS — Heat Edition and Decision Confidence — Heat Edition — that recalculates for the selected heat intensity, horizon and scenario. These are different demonstrator configurations of the same methodology, not conflicting calculations.
Current demonstrator is pre-decision and illustrative.
Option C: NVA EUR 80.2M · NVM 20.6× · Payback 10 months. Option D (unstructured): −EUR 335M revenue destruction.
This is the analytical engine behind the business-case proposition.
Two connected layers. One decision chain.
Not two separate products. The data and evidence architecture underlying the financial decision engine feeds the financial decision intelligence layer. Both use the same canonical EFR-IVL model and MASTER_RUNNER.
EFR-IVL™ is a decision-intelligence architecture connecting physical climate and sustainability evidence to financial consequences, investment appraisal and capital deployment. Physical Climate Risk to Capital Decisions is its flagship application — extreme heat is the current demonstration of that application, not the limit of what the architecture can do.
What does the evidence mean financially?
Translates physical-risk evidence through 14 engines into exposure, scenarios, adaptation economics and capital decisions.
Explore Financial Decision Intelligence →What evidence is required to make the financial decision defensible?
Makes the data acquisition and evidence layer explicit and auditable. Every parameter classified by source, quality, criticality and downstream financial impact. v4.0 supports v3.6 — it does not replace it: evidence feeds the financial engine, which feeds the business case, which supports the customer's decision.
v4.0 makes the hidden data layer visible: what's available, what's missing, how gaps affect decision readiness, and what strengthens the business case.
Explore Data & Evidence Architecture →One EFR-IVL architecture. Three commercial functions.
Why will the customer invest?
Creates the client-specific commercial proposition.
What is the financial consequence?
Translates evidence into financial exposure, scenarios, options and decisions.
Can we defend the business case?
Shows evidence availability, data gaps, acquisition requirements and decision readiness.
These are complementary functions within one architecture, not competing demonstrators.
Architecture first. Hazards second.
28 physical-risk pathways supported by the screening architecture. Extreme Heat is the current flagship end-to-end demonstrator.
🔵 Analytical pathway defined | ● Screening coverage
Five structural differences.
The architecture choices that carry the decision from evidence to capital deployment.
Physical-risk evidence translated into financially meaningful exposure — EBITDA at Risk, FCF and EV at Risk — rather than stopping at a hazard or risk score.
Every material financial output can be traced back through evidence, attribution and assumptions to where it originated.
Different forms of uncertainty — aleatory, epistemic, ambiguity — remain visible rather than being hidden inside a single confidence score.
Potential adaptation responses compared using financial measures such as value protected, NVA, NVM and payback.
The decision chain is designed to make assumptions, evidence gaps and governance constraints visible before capital decisions are made. Designed for decision assurance.
"What evidence do we need before deciding?"
EFR-IVL distinguishes what can be obtained from existing corporate reporting, what can be extracted from client systems, what can be derived, what requires specialist evidence and what requires expert judgement.
EFR-IVL does not own or generate this evidence. Its role: identify → acquire → classify → validate → attribute → translate → govern → connect to financial decision-making.
DRS — readiness of the decision data set. Evidence Readiness — strength and availability of the supporting evidence. Decision Confidence — confidence in the decision that the available evidence supports. A high score in one never overrides a failed gate in another. Investment Grade is a gate-based methodology within the demonstrator — it is not an externally validated assurance framework.
From Financial Risk to Adaptation Opportunity.
EFR-IVL provides the intelligence layer. Specialist partners provide engineering, project development, implementation, legal structuring and financing capabilities.
Future-stage capability is partnership-enabled and subject to technical, financial, legal and implementation due diligence. EFR-IVL does not develop, finance or implement adaptation projects.
EFR-IVL is designed to make sustainability-related investment decisions more financially transparent — helping decision-makers compare risks, interventions, capital requirements and potential value outcomes. It supports and informs these decisions; it does not allocate or guarantee capital.
How a sustainability company could use EFR-IVL around an existing customer proposition.
EFR-IVL can be used as a business-case development layer around an existing sustainability proposition.
The first objective is not to force a capital decision. It is to make the economic case sufficiently clear for the next decision.
EFR-IVL as the connecting layer.
EFR-IVL does not replace climate science, engineering or financing expertise. It provides the financial decision intelligence layer connecting them.
EFR-IVL is designed to help specialist companies move their customer conversation one step further — from identifying a sustainability problem to demonstrating why the customer's response may have financial value.

See how EFR-IVL could fit your solution.
If you already have a sustainability, climate-risk, adaptation, reporting or climate-tech proposition, we can explore how the EFR-IVL architecture could be configured around a target customer and decision.
The objective is to start a practical conversation around how EFR-IVL could strengthen an existing customer proposition.
The website's job is not to close a sale. Its job is to earn the next conversation.
Contact EFR-IVL™
If you would like to explore how EFR-IVL™ could strengthen a sustainability, climate-risk, adaptation, reporting or climate-tech customer proposition, I would be glad to discuss the potential fit.
Initial conversations are exploratory and focused on understanding whether the EFR-IVL™ decision-intelligence architecture could complement your existing customer proposition.
The financial translation problem behind physical climate risk.
An independent decision-intelligence architecture.
EFR-IVL was developed to address a persistent gap between physical-risk evidence and financial decision-making: how can climate-risk evidence be translated into financially structured exposure, adaptation economics and capital-allocation intelligence?
EFR-IVL is not a climate-risk scoring tool or an ESG reporting platform. It is the decision layer between evidence and financial action — connecting physical risk, evidence, uncertainty, financial translation, adaptation economics and capital decisions.
The methodology and demonstrators are now being developed for real-world testing, specialist validation and institutional engagement.
