The cost of inaction on climate change isn't abstract.
It shows up in your EBIT margin.
Enter three numbers about your business. We'll show you the margin you're on track to lose by 2030 and 2040 due to carbon pricing and sustainability regulation — and the cheapest ways to keep it.
Margin trajectory, 2025 → 2040
If this company does nothing, EBIT margin goes from 9.0% to −5.7%. Fill in your numbers on the right to see your version.
The dashed line at the top is the unpriced baseline — what your margin would be without carbon costs. The descending line shows the trajectory once carbon costs are applied. Each scenario produces a different curve: NGFS Net Zero 2050 is steepest; Current Policies barely moves.
Your inputs
Without action, your 9.2% margin falls to 4.0% by 2030, and becomes a −3.1% loss by 2040.
Two charts below show how operating cost and EBIT diverge from the unpriced baseline.
EBIT margin trajectory
Operating profit as a % of revenue, with and without carbon.
Operating cost
Annual total, with and without carbon.
Cutting that gap is what we do.
Unibloom Switch finds lower-carbon suppliers and materials so Scope 3 stops driving this curve — without changing what you sell.
What this means
The numbers above assume zero decarbonization progress between now and 2040. Under any credible 1.5°C scenario, carbon pricing becomes a non-discretionary line item — not an ESG metric. The companies that move first lock in lower costs for two decades. The ones that wait pay full freight on emissions they could have avoided.

Methodology
A transparent stress test for how carbon costs could affect operating margin. We translate scenario-based carbon prices into potential carbon costs, then show how those costs flow through to EBIT margin if the company takes no mitigating action.
What this calculates
The model answers one question: if carbon costs are imposed on your emissions, how much could your EBIT margin decline by 2040?
It is a first-order financial stress test, not a full climate-risk model. It focuses on carbon-cost exposure only — it does not model raw-material disruption, energy-price volatility, physical climate damages, or demand impacts.
The core formula
The calculation chain is straightforward:
Revenue is back-solved from the EBIT margin and operating cost you provide: revenue = TOC ÷ (1 − margin). Both revenue and operating cost grow over time with linear business growth and compound inflation. Emissions grow only with business growth.
Key assumptions
The model is intentionally conservative. It shows the full risk to operating profit if the business cannot mitigate the exposure.
- 100% cost absorption. The company absorbs the full carbon cost — no pass-through to customers, no supplier renegotiation.
- No decarbonization. Emissions intensity stays constant. The model does not assume any reduction from energy efficiency, supplier switching, or operational changes.
- Linear business growth. Real growth applied as
(1 + g × years). At 3% per year, that's 15% by 2030 and 45% by 2040. - Compound inflation. Applied to revenue and operating cost only — not to emissions or to already-nominal carbon prices.
- Constant baseline EBIT margin. The model assumes margin holds at your input value before carbon costs hit.
Where the carbon prices come from
Carbon prices are not entered manually — they are loaded from the scenario you pick. There are two sources:
NGFS scenarios
Sourced from the Network for Greening the Financial System Phase V (published November 2024). NGFS prices are shadow carbon prices — the implied cost per tonne of CO₂ required to make each climate pathway happen, not forecasts of actual taxes or market prices. Raw NGFS values are reported in real US$2010/tCO₂ and converted internally to nominal USD/tCO₂e for display.
Aii Net Zero Apparel Benchmark
Sourced from the Apparel Impact Institute's Cost of Inaction report. NGFS-derived but adjusted for apparel-sector exposure: $30/tCO₂e in 2025, $199/tCO₂e in 2030, $543/tCO₂e in 2040. Used as reported.
What this doesn't model
To keep the tool transparent and the conclusions defensible, several real-world dynamics are out of scope:
- Decarbonization pathways or emissions-intensity decline
- Carbon price pass-through to customers
- Supplier-specific cost sharing or contract renegotiation
- Country-specific carbon prices, regional sourcing mix, or border adjustments
- Carbon offsets, free allowances, or partial regulatory coverage
- Physical climate damage, raw-material shocks, energy-price volatility
- Tax effects, interest, valuation impact, or net income
Results are indicative and scenario-based. They are not forecasts, valuations, or accounting estimates. Actual outcomes depend on regulation, supplier exposure, emissions reductions, price pass-through, sourcing mix, and company-specific mitigation actions.
