Methodology Catalog

Active methodologies

The Carrot Network currently hosts two production methodologies under the BOLD (Breakthrough in Organics Landfill Diversion) family. Carrot provides the infrastructure; methodology frameworks and applications are developed by third parties.

Both methodologies verify the diversion of organic waste from landfills to composting facilities. BOLD Recycling certifies the recycling process itself and issues Tokenized Recycling Credits (TRC) with the on-chain symbol C-BIOW. BOLD Carbon (CH₄) quantifies the prevented methane emissions using the UNFCCC AMS-III.F methodology and issues Tokenized Carbon Credits (TCC) with the on-chain symbol C-CARB.CH4. Other methodologies, when added, may issue TRCs or TCCs with different on-chain symbols.

Structure of a catalog entry

Each methodology in the catalog is documented across four pages:

1. Overview — What the methodology does, its scope, waste types, and how it works. This is the main entry point for each methodology.
2. Framework (versioned) — The MvF specification: scope definition, eligibility criteria, key parameters, and verification requirements.
3. Application (versioned) — The MvA implementation: architecture, deployed rules, and source code references.
4. Rules — Framework rules and application rules catalogs, grouped by category, with descriptions of what each rule verifies.

How to contribute

New methodologies can be proposed by individuals, organizations, or research institutions with domain expertise in the target environmental claim. The process involves:

1. Aligning with the Carrot dMRV Standard requirements
2. Submitting a proposal for Community of Experts review
3. Authoring the MvF specification — see the MvF Author Guide
4. Implementing the MvA rule processors — see the MvA Developer Guide
