Every value has a path. Every decision has evidence.
See how the pipeline works01Capture
Registries, exchanges, ratings and satellite MRV are fetched as they are. Every raw record keeps its source and timestamp.
02Validate
Field contracts check each value before it counts. Schema drift and odd values go to review, not into your data.
03Resolve
When sources disagree, explicit authority rules decide, and the conflict stays visible.
04Trace
Every figure on a project page links back to the record it came from, including the gaps.
05Prove
One click exports an evidence pack for audit, data room or regulator.

Built on evidence, published for scrutiny.
The technical concepts and development of the QAVCM platform were presented at the 39th Annual Conference of the AKWI, hosted by the Berlin School of Economics and Law (HWR Berlin).

11,659 projects. One market, many lenses.
See the whole voluntary carbon market at once. Regroup every project by standard, category, region or status, and open any cluster to find its largest issuers.
Three things the fragmented market can't give you today.
Comparable data
One data model makes credits from every standard comparable side by side.
Explainable valuation
A fair value for each credit, with every driver shown in euros.
Smart procurement routing
Orders routed by evidence and risk, with every quote checked before purchase.
- 01
No inventory
QAVCM never owns or resells credits, so it has no stake in which project wins.
- 02
No paid placement
Projects and venues cannot pay to be listed, ranked or routed to.
- 03
Open methods
Scores and fair values follow a peer-reviewed method, and every figure links to its source.
One request, comparable offers.
Most credit prices sit in quotes, not order books. So we run one request across suppliers and venues and make the answers comparable. Nothing is bought until a person approves.

Volume, budget, type, region and reporting goal.
Shortlist
Registry data and quality checks narrow the field.
Request quotes
From suppliers and venues at once, made comparable.
Approve and retire
The buyer signs off. Retirement records for the report.
Offer it to your clients.
We set up QAVCM in the background, under your brand. Your relationship managers get a carbon offer without building a desk.
