What the platform does with what you tell it
Nothing here is a black box. This page sets out the exact fields collected, how a fit score is computed, and how the internal qualification works.
1 · The requirement
Five steps, plus a conditional sixth for aviation compliance.
Your organisation
01Who is buying, who signs, and where you are in onboarding.
9 required of 25 fields · ~3 min
Why you need credits
02The driver behind the purchase, and how far along your decarbonisation is.
3 required of 11 fields · ~2 min
What you want to buy
03Volume, budget, timing and how you would like the deal structured.
5 required of 30 fields · ~4 min
Credit specification
04Which programmes, project types and vintages you will accept.
3 required of 30 fields · ~5 min
CORSIA parameters
04AconditionalAviation compliance detail. Shown because you asked for CORSIA-eligible units.

Use, retirement & claims
05How the credits will be retired and what you intend to say publicly.

2 · Matching
Two stages: hard requirements that block, then weighted preferences that rank.
Blockers
A lot is ineligible when it fails something you stated as a hard requirement.
- Registry or unit type outside your accepted list
- Vintage outside your window
- Price above your stated ceiling
- Not issued when you require issued credits
- Volume below your minimum offer size
- Missing a label you marked Required — CCP, CORSIA, Article 6, corresponding adjustment
- Trips one of your Absolute exclusions
Ineligible lots are still shown, with the reason, so you can see which constraint is doing the filtering.
Fit score
A weighted average over the preferences you actually expressed, from 0 to 100. State no preferences and there is no score — a blank requirement cannot produce a meaningful ranking.
- Price against your target (not your ceiling)
- How much of your volume one lot covers
- Reduction / avoidance / removal, and project category
- Preferred activities, geographies and scale
- Labels you marked Preferred rather than Required
- Direct-from-project sourcing and payment terms
- Conditional and Preference exclusions, which downrank rather than block
3 · Internal qualification
What our team does with your submission. Shown for transparency; buyers do not see their own score.
Knock-out gates
Any failure caps the outcome at Decline, whatever the score.
- G1 Integrity & KYC
- Buyer and jurisdiction pass sanctions and KYC screening.
- G2 Mandate fit
- No requirement that cannot be supported — excluded registry as sole option, unsupportable claim, required CORSIA programme not TAB-approved for the stated period, or LOA/CA unavailable where required.
- G3 Minimum viable opportunity
- At least one of: budget, decision authority, defined volume.
- G4 Independence / conflict
- No conflict of interest, e.g. verifying an in-house-prepared inventory.
Weighted criteria
Each scored 1–5 by an analyst, then weighted to a score out of 100.
≥75 Tier A · 55–74 Tier B · 40–54 Tier C · below 40 or any gate failure, Decline.
4 · Indicative price bands
Analyst estimates used for budget sanity checks.
