BOLD Carbon (CH₄) Application Rules v1.0.0
Complete catalog of application rules for the BOLD Carbon (CH₄) framework v1.0.0 — execution order, descriptions, and source code.
Overview
These are the application rules — the executable validation logic that runs against each MassID document. Each rule evaluates a document and returns PASSED or FAILED with an explanation.
Each application rule satisfies one or more framework rules from the BOLD Carbon (CH₄) methodology framework. See the "Implements framework rules" section in each rule's details for the mapping.
The BOLD Carbon (CH₄) framework defines a set of open-source rules to verify that organic waste has been properly diverted from landfills and composted, preventing methane emissions.
BOLD Carbon (CH₄) shares most rules with BOLD Recycling and adds methodology-specific rules for emissions calculation and geographic boundary validation.
Rules execute in a defined order across three scopes: MassID validation, GasID certificate issuance, and credit order settlement.
All rules are licensed under LGPL-3.0: github.com/carrot-foundation/methodology-rules
MassID rules
These rules validate individual MassID documents. They execute in the order shown. Rules 1–19 are shared with BOLD Recycling; rules 20–21 are Carbon-exclusive.
GasID rules
These rules execute after all MassID rules pass and the GasID certificate is issued.
Credit Order rules
These rules execute when credit order documents are processed.
See the Rewards Distribution Policy for the full percentage breakdown by actor type and waste category.
