What emits and by how much per unit of activity
emissionSources`: stationary, mobile and process sources and their ownership · `emissionFactors`: per-activity release coefficients and their provenance
This meta-model describes quantified releases of substances and energy into the environment: the sources that cause them, the pathways they take to air, water and soil, the factors and measurements that quantify them, the abatement measures that reduce them, and the verification that makes the numbers trustworthy. It is its own model because an emission record is a derived claim: it must be reproducible from method plus activity data and independently verifiable, which imposes an evidence discipline that the underlying activity models do not need.
What emits and by how much per unit of activity
emissionSources`: stationary, mobile and process sources and their ownership · `emissionFactors`: per-activity release coefficients and their provenance
How quantities are established
directMeasurement`: continuous and sampled monitoring series · `estimationMethods`: calculation methods combining factors with activity data
Where releases go
releasePathways`: routes to air, water and soil · `ambientFlux`: dispersion, deposition and uptake by sinks
Reducing and attesting
abatementMeasures`: interventions that reduce source output · `verification`: independent attestation of quantified records
Catalogue-native findings must describe the information grouped by each layer. This legacy version does not declare them separately.
Questions, artifact requirements and serial naming rules are required by Vercy vNext; they remain unassigned in this reference version.
Format-independent core. Concrete artifact formats and naming prefixes are not declared in this legacy version.
CRUD procedures and interface bindings are not declared in this legacy version.
The emitting owner stewards its source and quantification records, while an independent environmental verifier archetype holds attestation access and a statistics office archetype stewards published aggregates. Access is granted by the respective steward through the catalogue's S1/S2 ownership and access models, with verification trails audited via S4.
