Deliver a coordinated REC and carbon credit registry so a single megawatt hour cannot be counted in both markets, giving corporate buyers full confidence in credit integrity. A carbon auditor queries the chain and confirms zero double-counting in a single day.
Bind two fragmented markets to one ledger so the same clean megawatt hour is never sold twice.
01.
The Energy Meter Oracle feeds one verified generation figure into both registries, so RECs and carbon credits draw from the same metered source of truth.
02.
The Carbon Credits MRV and Registry and Renewable Energy Certificates Registry modules cross-check each other, blocking a carbon credit where the same output already backs a REC.
03.
Each carbon credit carries a measurement, reporting, and verification record tied to real generation, giving auditors an evidence trail rather than a claim.
04.
Retiring a REC and issuing a carbon credit for the same megawatt hour are made mutually exclusive at the protocol level, structurally preventing double-counting.
05.
A corporate's carbon auditor queries the chain directly to confirm no overlap between REC retirement and credit issuance, clearing findings in a day.
06.
Corporate buyers trace each credit to its generation batch and its exclusivity lock, so credit integrity is provable rather than asserted.
Follow a single megawatt hour as it is metered, allocated to one market, issued as a credit, and cleared by an auditor.

Cerulea decomposes coordinated credit issuance into modular contracts. Each layer verifies generation, allocates it exclusively, issues credits, and exposes the record to auditors.
Coordinated credit issuance is a horizontal capability. Here is how different actors in the renewable and carbon markets put the shared ledger to work.
Monetize generation in both the REC and carbon markets from one metered basis, choosing the allocation per megawatt hour with the assurance no output is sold twice.
Key Asset Types
Purchase carbon credits with a provable evidence trail and exclusivity lock, so ESG claims survive audit and reputational scrutiny.
Key Asset Types
Confirm the absence of double-counting between markets directly on-chain, clearing findings in a day instead of reconciling two fragmented registries.
Key Asset Types
Whether you are bridging a developer's metering systems or letting standards bodies verify natively, Cerulea routes both into one coordinated credit ledger.
For renewable developers on legacy metering and MRV tools. Verified output is translated into signed on-chain allocations through the API gateway.

Building a dual REC and carbon registry with a shared basis, exclusivity locks, and auditor tooling from scratch requires specialised engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects environmental market integration benchmarks. Reconciling two registries, building custom exclusivity logic, and deploying auditor tooling for an average program takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your allocation and issuance rules into pre-audited WebAssembly binaries and provisions the coordinated registry instantly.
