Impact, sustainability and environmental reporting
Inventory boundary, activity, impact factor, calculation and disclosure. Methodologies and assumptions are versioned; financial costs do not substitute for impact.

Published results
Research note, in Russian: Canonical/runtime promotion remains governed by the package allocation, identity and dependency holds.
Subject boundary and candidate types
- ImpactBoundary
- ActivityData
- EmissionFactor
- ImpactCalculation
- SustainabilityDisclosure
Deep research questions
- How to distinguish the operational and organizational perimeter?
- How to justify a conversion factor?
- How to avoid double counting between chain participants?
Verifiable invariants
- A calculation pins the method and the factor
- Units are consistent
- Estimate and measurement are flagged separately
End-to-end acceptance scenario
Two calculation methods and a perimeter change yield explainable discrepancies without false comparability.
Negative case
Cloud spend is automatically treated as an exact emissions volume.
Approaches to compare
- W3C ORG: site and organizational relations
- IDTA AAS/GS1: the asset and its physical state
- GHG Protocol for impact, or CAFM/EAM for location and usage

Semantic fit requires boundary research; a published model does not by itself complete this card.
Result requirements
Every card is executed together with the full research contract: definitions, fields and cardinalities, lifecycle, sources, data mastership, rights, the five object facets, at least eight invariants, positive and negative examples, dependencies, migration and applicability limits.
