The CBAM Common Central Platform (CCP) is the single EU-wide IT system that will sell, repurchase, and reconcile CBAM certificates for all 27 member states starting February 1, 2027. The European Commission published the call for tender to build and run the CCP in the Official Journal on February 11, 2026, and the tender closed on April 6, 2026. The winning contractor must deliver a pre-operational version with core sales, repurchase, and reconciliation functionality ready for testing by August 31, 2026, then bring the platform to full operational readiness for the February 1, 2027 launch. This is where every authorized CBAM declarant will buy certificates once sales begin.
This article covers what the CCP is, the build timeline from tender to launch, how declarants will reach it to buy certificates, and what remains unconfirmed as of July 2026.
What Is the CBAM Common Central Platform?
The CBAM Common Central Platform is the centralized payment and transaction system through which national competent authorities (NCAs) sell CBAM certificates to authorized declarants, buy back unused certificates, and reconcile certificate holdings against reported import data. It replaces what would otherwise be 27 separate national certificate-sale systems with one shared platform, procured jointly rather than built individually by each member state.
The legal basis for a single sales platform sits in Regulation (EU) 2023/956 as amended by Regulation (EU) 2025/2083, which establishes February 1, 2027 as the date on which CBAM certificate sales begin. The CCP is the operational infrastructure that makes that date real: without it, no member state has a mechanism to sell a certificate. The CBAM certificates guide covers the certificate lifecycle itself, including price calculation and the buyback right; this article focuses on the platform that runs all of it.
CBAM Common Central Platform Timeline: From Tender to Launch
Six confirmed dates define the CCP build-out, from the joint procurement agreement to the February 2027 launch. The table below lists each milestone in order.
| Date | Milestone |
|---|---|
| December 15, 2025 | Joint Procurement Agreement signed by all 27 EU member states and the European Commission |
| February 11, 2026 | Call for tender published in the Official Journal, run by DG TAXUD |
| April 6, 2026 | Tender submission deadline (5:00 PM CET) |
| July 9, 2026 | Commission opens public feedback on the draft Implementing Regulation governing certificate sale and repurchase conditions via the CCP |
| August 31, 2026 | Contractor must deliver a pre-operational CCP with core sales, repurchase, and reconciliation functionality, ready for testing |
| February 1, 2027 | CCP reaches full operational readiness; certificate sales begin |
Two of these dates carry the most weight for importers. August 31, 2026 is the internal testing milestone, not a public launch, so declarants should not expect access before then. The draft Implementing Regulation opened for feedback on July 9, 2026 remains in consultation as of this writing, with the feedback window open until August 6, 2026; it sets out the detailed conditions for how sales and repurchases run on the platform, and its provisions are not yet final. The full regulatory calendar, including authorization and declaration deadlines that surround this build-out, is mapped in the CBAM timeline.
Where to Buy CBAM Certificates: How Declarants Reach the CCP
Authorized declarants will buy CBAM certificates through their national competent authority, with the CCP running as the shared backend behind every NCA's sales function. There is no separate CCP login and no alternative purchase channel: the platform sits behind the same CBAM Registry account a declarant already uses for authorization and declarations, not a new portal to register for.
The practical purchase path runs through four steps.
- Hold authorized CBAM declarant status. Only an authorized declarant can access certificate sales; unauthorized imports above the 50-tonne de minimis threshold trigger penalties instead. The CBAM authorized declarant guide covers the application process.
- Log into the CBAM Registry. Declarants use the same UUM&DS credentials that grant access to the CBAM Registry for reporting and declarations.
- Open the certificate purchase module from February 1, 2027. The module displays current holdings, the published certificate price, and the purchase order screen, all running on CCP infrastructure even though the declarant never sees the CCP by name.
- Submit the purchase order to the NCA. The order routes through the CCP, which processes the sale, records the holding, and updates the reconciliation data the NCA uses to check compliance.
A full step-by-step walkthrough of pricing, budgeting, and purchase timing is covered in how to buy CBAM certificates; this section covers only where that process physically runs.
What the CCP Actually Does: Sales, Repurchase, and Reconciliation
The Commission's tender documentation names three core functions the CCP must support by the August 31, 2026 pre-operational milestone. Each function serves a different stage of the certificate lifecycle.
- Sales. Processes the purchase of certificates by authorized declarants at the applicable EU ETS-linked price, records the transaction, and credits the declarant's holdings.
- Repurchase. Executes the buyback right, letting declarants sell back up to 50% of a given year's purchases to their NCA at the original purchase price, up to the October 31 deadline.
- Reconciliation. Matches recorded certificate holdings against reported import and embedded emissions data, the check that underpins the quarterly holding requirement and the annual surrender.
Reconciliation is the least publicly documented of the three functions; the Commission's tender materials name it as a required capability without detailing the exact interface a declarant or NCA will see. Treat the operational specifics of reconciliation as unconfirmed until the Commission publishes further guidance or the platform itself goes live for testing.
Quarterly Holding and Buyback Run Through the Same Platform
The CCP is also the system that enforces the two ongoing obligations declarants carry after their first purchase: the quarterly holding requirement and the buyback right. Both depend on the platform's sales and repurchase functions working correctly from day one.
The quarterly holding requirement obliges every authorized declarant to hold certificates equal to at least 50% of cumulative embedded emissions since January 1 of the current year, checked at each quarter-end. The full mechanics, including a worked calculation, are covered in the CBAM quarterly holding guide. The buyback right lets a declarant sell back up to half of a year's purchases at the price originally paid, a hedge against over-buying that only works if the CCP's repurchase function is live and accurate. Neither obligation applies before February 1, 2027, because no certificates exist to hold or buy back until the platform opens.
Who Is Building the CBAM Certificate Platform? Contractor and Award Status
No contract award for the CBAM Common Central Platform had been publicly announced as of July 11, 2026. The tender closed April 6, 2026, and the Commission's published milestones require a pre-operational version by August 31, 2026, which implies an award decision and contract signature well before that date, but the identity of the winning contractor has not appeared in Commission communications or the TED (Tenders Electronic Daily) notices reviewed for this article.
Treat any vendor name circulating in trade press or LinkedIn posts as unverified until the Commission confirms it directly. What is confirmed is the procurement structure: the Joint Procurement Agreement signed December 15, 2025 by all 27 member states and the Commission means a single contractor builds and operates the CCP for the whole EU, run under DG TAXUD, rather than each NCA procuring its own system.
Is the CCP at Risk of Missing Its February 2027 Deadline?
There is no public evidence as of July 2026 that the CCP timeline has slipped. The Commission has hit its published milestones so far: the Joint Procurement Agreement, the Official Journal publication, the tender close, and the July 9, 2026 opening of feedback on the sale-and-repurchase draft Implementing Regulation all landed on or ahead of schedule. The remaining risk sits between the August 31, 2026 pre-operational milestone and the February 1, 2027 launch, a five-month window for testing, fixing, and scaling a system that all 27 member states depend on simultaneously.
Declarants do not need to change their preparation because of this uncertainty. The first annual CBAM declaration remains due September 30, 2027, covering 2026 imports, and the 2026 certificate price is calculated retroactively as a quarterly EU ETS average, so nothing about the platform's build schedule changes what data a declarant needs to collect now.
Frequently Asked Questions About the CBAM Common Central Platform
When Does the CBAM Common Central Platform Go Live?
The CCP reaches full operational readiness and opens certificate sales on February 1, 2027. A pre-operational version with core sales, repurchase, and reconciliation functionality is due by August 31, 2026, but that milestone is for contractor testing, not public or declarant access.
Can Declarants Test the Platform Before February 2027?
No public testing window for declarants has been announced as of July 2026. The August 31, 2026 pre-operational milestone covers the contractor's own testing of core functionality; the Commission has not published plans for a declarant-facing pilot or beta period ahead of the February 1, 2027 launch.
Is There a Secondary Market for CBAM Certificates Outside the CCP?
No. CBAM certificates can only be bought from and sold back to a declarant's national competent authority through the CCP. There is no exchange, no broker, and no bilateral trading between authorized declarants, which distinguishes CBAM certificates from EU ETS allowances traded on platforms such as EEX.
Who Operates the CBAM Common Central Platform?
The European Commission's Directorate-General for Taxation and Customs Union (DG TAXUD) manages the procurement and oversight of the CCP under the Joint Procurement Agreement signed by all 27 EU member states on December 15, 2025. A single external contractor builds and runs the platform on the Commission's behalf; that contractor's identity was not publicly confirmed as of July 11, 2026.
What Happens to the Draft Rules on Sale and Repurchase Conditions?
The Commission opened public feedback on a draft Implementing Regulation setting the detailed conditions for certificate sale and repurchase via the CCP on July 9, 2026, with feedback open until August 6, 2026. As a draft still in consultation, its provisions are not final and should not be treated as binding until the Commission adopts the regulation.
