Nature-Adjusted Economic Value (NAEV)

– Concept Paper –

In order to transfer the Sustainserv NMGA approach into the management world of CEOs and CFOs, the gap between ecological tipping points and financial value creation must be closed. Similar to how Economic Value Added (EVA)deducts capital costs from operating profit, NAEV integrates “ecological debt” and the risk of system collapse into the performance calculation.

1. The basic formula

NAEV is calculated from adjusted operating income minus a risk-weighted natural capital fee:

The terms:

1. NOPAT (Net Operating Profit After Tax): The ordinary operating profit after tax.
2. R_Pareto  (Nature Risk Discount): This is the weighted discount on profit. It is calculated based on the gross value added (GVA) of the locations concerned. Only the risk of the identified “kill factors” (the critical 20%) is taken into account.

• WACC (Weighted Average Cost of Capital): The conventional cost of capital.
• 𝜙_NMGA  (Nature Risk Premium): The risk premium derived directly from the 9 cascades.

 2. Data requirements for the NAEV calculation

In order to bring the formula to life, controlling requires data from three different sources:

A. Financial data (from ERP/accounting)

• NOPAT: Operating profit after taxes.
• Invested capital: Total of equity and interest-bearing debt.
• GVA (Gross Value Added) per location: To assign economic dependence geographically.
• Weighted average cost of capital (WACC): The market interest rate for the specific risk profile of the sector.

 B. Scientific data (leading indicators)

• Distance to tipping pointD_TP: A value between 0 (safe) and 1 (collapse), based on real-time data (e.g., groundwater level trend, habitat fragmentation).
• Regeneration rate: The speed at which the natural asset being used recovers (important for assessing delays).

C. Audit scores (from the NMGA)

• Compliance gap: The degree of compliance with the 9 cascades (0-100%).

 3. Calculation of the Nature Risk Premium𝜙

The nature risk premiumis not a flat rate, but the result of a structured rating across the three phases of the NMGA audit. It is added as an additional percentage (basis points) to the WACC.

The weighting of the cascade scores (S):

Each phase is rated with a score from 0 (no risk) to 1 (maximum risk).

• 𝜔1 (Physical – 50% weighting): Since no business is possible without the physical basis (cascade 1.1 – 1.3), this phase has the highest weighting.
• 𝜔2 (Social – 25% weight): Measures the risk of market exclusion and reputation (cascade 2.1 – 2.3).
• 𝜔3 (Financial – 25% weight): Measures systemic long-tail risks and investability (Cascade 3.1 – 3.3).
• κ (scaling factor): An industry-specific factor (e.g., 0.05 for high-impact industries such as chemicals/agriculture) that defines the maximum risk premium.

Example: A chemical company with critical water dependency has a poor physical score (S=0.8) but good reputation management (S=0.2). The resulting _{NMGA ()} premium could increase the WACC, which would significantly reduce the NAEV.

 4. Pareto prioritization in the NAEV

Instead of laboriously pricing all 20+ ecosystem services, the NAEV focuses exclusively on the identified kill factorswhen calculating R_Pareto.

• Example: If “ultrapure water” is the only kill factor for a semiconductor manufacturer, accounting for 80% of the risk, then the entire risk discount in the NAEV is based solely on the aquifer depletion rate at this one site.
• Advantage: This prevents the indicator from being “diluted” by insignificant issues (such as the beehives on the roof) and creates radical clarity for management.

 5. Strategic interpretation: NAEV vs. EVA

Feature	Classic EVA	Nature-Adjusted EV (NAEV)
Focus	Capital efficiency (inside-out)	Systemic resilience (outside-in)
Profit base	Realized profit	Expected, naturally secured profit
Risk interest rate	Market risk (beta)	Threshold risk (tipping points)
Management signal	“Invest where the return is > WACC.”	“Invest where the system is stable.”

 6. Conclusion for controlling

NAEV reveals the materiality gap. A positive EVA can become a negative NAEV when natural risks are taken into account. This is the ultimate warning signal for investors: although the company is currently making profits, it is “consuming” its ecological base so quickly that the terminal valueis approaching zero.

7. The logic of the model

7.1. Factoring NOPAT with the nature risk discount:The nature risk discount term acts as a safety discount on operating profitability. If a company’s locations are not exposed to any risk from the identified “kill factors,” NOPAT remains unaffected. This discount represents the “EBITDA at risk” – i.e., the portion of profit that is immediately lost if the ecosystem service in question (e.g., water supply) is disrupted. NB. NOPAT is a more useful term than EBITDA as depreciation is computed into the term (unlike in EBITDA).

7.2. Linking cost of capital (WACC) and invested capital: In the financial world, WACC is the price a company must pay to use capital. By adding the nature risk premium to WACC, we increase this price. Multiplying this by the invested capitalthen calculates the absolute euro amount that the company must generate in order to “pay” both the investors and the additional nature risks. This is the imputed hurdle rate in absolute terms.

7.3. Subtracting the cost of capital x invested capital from the discounted NOPAT (residual income concept):This step follows the logic of “economic profit.” A company only creates real value when its profit (adjusted for natural risks) is higher than its cost of capital (increased by natural risks).

• If the result is positive, the company creates value while taking its ecological dependencies into account.
• If it is negative, the company is effectively “burning” its natural capital faster than it is generating economic value.

In summary, while the first part of the formula (discounted NOPAT) examines how much money could be lost today due to natural risks, the second part (increased capital costs) examines how expensive the futureof the company will be due to these risks.
