Say what you need.
See what actually matches.
Buyers describe a requirement once — registries, vintages, CORSIA and Article 6 conditions, exclusions and all. Sellers list real inventory with real prices. Verdex scores every lot against every requirement and tells both sides exactly why something matched, or why it did not.

Why this is not another form
The underlying specification runs to 154 fields. You are asked for 31. Everything else appears only when it becomes relevant to what you already told us.
Progressive, not exhaustive
Each step opens with the fields that matter. Optional detail sits behind a single "add more" control, and conditional sections — CORSIA, removals durability, corresponding adjustments — appear only once your answers call for them.
One specification, both sides
Sellers answer the mirror image of what buyers ask. That is what makes a fit score meaningful instead of decorative: every factor traces back to a field one side filled in.
Exclusions that actually screen
Policy exclusions are pre-applied. Add your own from a preset library or free-form, and they filter live — absolute rules block a lot outright, conditional ones just push it down the list.

List once, sell many vintages
Register the project once — registry ID, methodology, host country, integrity labels, authorisation status. Then attach as many inventory lots as you hold: vintage, unit type, quantity available and your asking price.
- Quantity and price per lot, updated whenever you want
- Show your price publicly or keep it on request
- See which live buyer requirements your lot already satisfies
- Take enquiries with the buyer’s volume and context attached
