—per unit invested

Underlying data, sources & inputs

Benefits (PV) the primary public value streams.
Cost (PV) the action cost profile the case declares.
Discount and horizon per the case calendar.

How robust the result is—

Scenario figures show how the result moves under other assumptions. The QA-checked, signed result is the headline account. Double-check any scenario figure before relying on it.

Underlying data, sources & inputs

Trajectories the climate pathways the case declares.
Shown at the selected intervention level; the case composes any climate × intervention pairing.

How the value accrues over time—

BenefitsCostNet (the gap)Cumulative present value (M)

The shaded gap between the curves is the cumulative net public value, accruing year by year.

Underlying data, sources & inputs

Each stream’s annual value is discounted year-by-year. Net = Σ discounted benefits − Σ discounted cost.

Confidence in the evidence—

The share of the public value total that rests on evidence-sourced rates, read from this run's engine account.

Underlying data, sources & inputs

Sourced evidence-based rates from the source registry.
Indicative operational inputs the user can replace.
For the business accounts (not in the public value total) the market/financial expressions carried forward.

Capture potential—

“Capturable” means public value an entity — a business, scheme or public body — could realistically turn into revenue or avoided cost, rather than diffuse benefit to society. It is the part that becomes money in the business accounts.

Capturable a clear route to revenue or saving · Partial some of it · Non-market real public value, no capture route. Read from the assessment’s value-capture flags, not derived here.

Underlying data, sources & inputs

In the public value total the components aggregated into the net public value.
Taken forward the market/financial expressions for the business accounts, never aggregated into the public value total.

The QA record—

—Two independent tiers checked this assessment before it was shown — an automated tier on every run, and a separate, different-vendor AI model reviewing the whole write-up.

Tier 1 · automated checksevery run · no AI

Data contracts & schema validEvery figure carries provenance (real vs indicative)Licence note on every cited sourceNo double-counting across value streamsCurrency & price-year consistentTotals reconcile (benefits − cost = net)Limitations & caveats disclosed

Tier 2 · independent reviewseparate AI vendor

Write-up matches the computed figuresEach value supported by its cited sourceNo overstatement or distortion of results

Both tiers run at Step 5 (mid-assessment) and Step 8 (final). The result cannot be handed off unless the final check passes.

Underlying data, sources & inputs

Every check names the record it validated in the run’s observation log. The judge is a separate-vendor model, run in record/replay so its verdict is reproducible. A failed critical check halts the run before commit.
