Changelog — Carbon Tracking
Frozen Baseline discipline. Material changes only.
Version 1.0
Published: 2026-04-16
- Initial structural baseline publication.
- Definition of carbon tracking established as a framework for observing, measuring, and attributing emissions across system activities.
- Scope boundaries formalized (included / excluded).
- Structural phase model introduced (activity identification → emission measurement → attribution → tracking and recording).
- Institutional reference sources documented.
- Mandatory legal, privacy, terms, and license pages implemented.
- 2026-07-22 — Added root-level llms.txt following LLMS Baseline v2.0 to provide a canonical machine-readable orientation layer for published resources.
- 2026-09-06 — Established the CarbonTracking Persistent Record Layer (PRL) reference implementation. Added stable fragment identifiers for “Emission Measurement” and “Attribution” on /method/, published the corresponding Persistent Records through the dedicated Record Authority at records.carbontracking.de, added an RFC 9264 linkset with human-visible Persistent Record references on /method/ to expose the Core-to-Record relationships, and extended llms.txt to expose the PRL resources for machine-readable orientation. No definitional, scope, or Core JSON-LD changes.
- 2026-09-25 — Removed the email property from Organization JSON-LD across the published site to align the implementation with the established portfolio governance baseline. Frontend contact information remains unchanged. No change to the domain’s semantic definition, scope, or structural model.
Status: Frozen Baseline
Change Policy
Changes are recorded only if:
- The definitional boundary materially evolves.
- A structural clarification alters conceptual framing.
- Primary institutional reference frameworks materially change.
- A compliance-relevant correction is required for accuracy.
Minor editorial, stylistic, or formatting corrections are not versioned.
Versioning Logic
Version increments follow semantic clarity rules:
- Major increment — Definitional or structural shift.
- Minor increment — Material clarification without conceptual shift.
- No increment — Editorial refinement only.
