The Standard - Circular Economy Crediting Program
Methodology governance, quality assurance, and credit integrity safeguards.
Last updated on
What is a standard in environmental markets?
In environmental markets, a standard is the crediting program that defines and governs the rules for how environmental credits are measured and verified. The standards body approves methodologies, manages their lifecycle — from initial design through versioning to eventual discontinuation — and ensures that the credits produced under those methodologies meet a consistent level of quality.
Without a standards body, there is no independent authority governing what counts as a valid credit. The standard is the layer of trust between the project that generates environmental impact and the buyer who pays for it.
For the broader map of standards, methodologies, digital MRV (dMRV), registry, VVBs, and buyers, see Credit Ecosystem Roles.
Why Carrot is a standard
Carrot operates as a standards and governance body for methodologies, methodology verification frameworks, and dMRV applications approved for use on the Carrot Network. It defines the Carrot dMRV Standard, evaluates whether submitted methodologies and frameworks meet that standard, and manages their lifecycle through approval, versioning, and discontinuation.
The Carrot dMRV Standard establishes the common ground that allows multiple methodologies to coexist on shared infrastructure, each contributing verified environmental impact data to the same ecosystem.
This independent-authority role is part of the reason the Carrot Network is built as digital public infrastructure, not as a private verification product.
Crediting architecture
The architecture moves from shared program rules to public credit records. The Protocol defines the domain-wide requirements. The Standard governs methodologies; each methodology is operationalized through a Methodology Verification Framework (MvF); dMRV applications execute those rules; and the Registry records the resulting credit lifecycle.
Circular economy crediting architecture
The architecture starts with the Protocol and the Standard as the circular economy crediting program, then moves through an approved Methodology and its dMRV Framework into dMRV execution. dMRV applications execute framework rules and produce auditable evidence; the Registry records the resulting credit lifecycle from issuance to retirement.
From shared protocol rules to the public credit record.
What this means for credit quality
Every credit issued within the Carrot Network is backed by a methodology governed under the Carrot dMRV Standard. Three properties support credit integrity:
- Open-source rules — All verification logic is published under an open-source license and publicly auditable. Anyone can inspect the rules that produced a given outcome.
- Automated, auditable verification — Verification is executed by deterministic software (MvAs) that produces the same result for the same input, every time. Results are recorded in the public registry and viewable through the Carrot Explorer.
- Independent assurance — Third-party Validation and Verification Bodies (VVBs) provide independent review, adding a layer of oversight beyond the automated process.
Core principles
The Carrot dMRV Standard is built on five principles that apply to every methodology in the network: integrity & traceability, additionality & verifiability, standardization & comparability, interoperability & automation, and transparency & auditability. Together, they ensure that every credit is backed by auditable, reproducible evidence — from the original supply chain event to the final credit issuance.
Compliance and enforcement
Methodology compliance is currently managed by the Carrot Foundation, which oversees adherence to the Carrot dMRV Standard. As the ecosystem matures, enforcement responsibilities will progressively expand to include community participation. See Governance for how this evolution is structured.
Participants who fail to meet the requirements of the Carrot Standard face enforcement actions. Depending on the severity and nature of the violation, consequences may include suspension or removal from the network, and credits may be withheld or revoked. These measures protect the integrity of the credits issued under the network and maintain trust for all participants.
