1. Outcome
Section titled “1. Outcome”1After reading this Circular, you will understand how the Technical Guidance on Ocean Accounting is organised, the meta-structure each circular follows, the conventions for versioning, stability classification, and dependency tracking, and the production process for circulars. This Circular is a reference for authors, editors, and users of the Technical Guidance.
2. Requirements
Section titled “2. Requirements”1None.
3. Organisation of the Technical Guidance
Section titled “3. Organisation of the Technical Guidance”3.1 Section Structure
Section titled “3.1 Section Structure”1The Technical Guidance is organised into seven sections:
| Section | Title | Circulars | Purpose |
|---|---|---|---|
| 0 | Concepts, Definitions and Front Matter | 8 (TG-0.1—0.8) | Foundational materials: conceptual framework, standards, glossary, QA principles |
| 1 | Using Ocean Accounts in Decision-Making | 13 (TG-1.0—1.12) | Policy applications: how accounts inform planning, finance, and management. TG-1.0 is the section-framing circular: it is the entry point to the section, and establishes the vocabulary the other twelve use |
| 2 | Indicators | 13 (TG-2.1—2.13) | Indicator methods: deriving decision-relevant metrics from accounts. One exception: TG-2.12 Spatial Data Frameworks is a data-methods circular on the Section 4 definition, numbered here for historical reasons and to be renumbered at the Second Edition |
| 3 | Accounts Compilation | 16 (TG-3.1—3.16) | Core methodology: building accounts tables from data sources |
| 4 | Data Methods | 12 (TG-4.1—4.12) | Data methods: collection, processing, quality assurance |
| 5 | Geographic and Thematic Case Studies | 12 (TG-5.1—5.13; 5.12 reserved) | Implementation examples from partner countries |
| 6 | Thematic Methods | 15 (TG-6.1—6.15) | Deep-dive methods for specific ecosystems, sectors, asset classes and intervention classes |
3.2 Circular Numbering
Section titled “3.2 Circular Numbering”1Each circular is identified by: TG-[Section].[Number]
- 2TG-0.1: Section 0, Circular 1
- 3TG-6.14: Section 6, Circular 14 (Marine and Coastal Tourism Accounting)
4The number .0 is reserved for a section-framing circular: one that establishes the vocabulary and the routing the rest of its section depends on, and that carries no method of its own. Section 1 has one, TG-1.0, because the terminology of ocean economy measurement is used by the other twelve circulars in that section. Sections without such a circular begin at .1, and a .0 is not to be created to complete a pattern.
5The version number is recorded in the circular’s YAML frontmatter as a separate version field (e.g., version: "0.2.0"). Major increments reflect substantive content changes, whilst minor increments reflect editorial improvements.
3.3 Stability Classification (Badges)
Section titled “3.3 Stability Classification (Badges)”1Each circular carries a stability badge indicating its relationship to underlying standards. See TG-0.5 Navigating the Technical Guidance for full definitions. Summary:
| Badge | Meaning | Update Trigger |
|---|---|---|
| Core | Based on adopted international standards (2025 SNA, SEEA CF, SEEA EA) | Only when standards are formally revised |
| Applied | Interprets standards for ocean context; stable but may evolve | Annual review cycle |
| Emerging | Addresses topics where standards are still developing | Updated as standards crystallise |
4. Circular Meta-Structure
Section titled “4. Circular Meta-Structure”1All circulars follow a standard structure to ensure consistency for readers. This section specifies the template for circular authors.
4.1 YAML Frontmatter Specification
Section titled “4.1 YAML Frontmatter Specification”1Every circular begins with machine-readable YAML frontmatter:
---title: "Circular Title" # Required: Full titlecircular_id: TG-X.Y # Required: Circular identifierbadge: Applied # Required: Core | Applied | Emergingversion: "0.1.0" # Required: consultation version (0.Major.Minor)circular_status: Draft # Required: Draft | Completed | Plannedlast_updated: Month Year # Required: e.g. May 2026prerequisites: # Required: List of prerequisite circular IDs (empty array [] if none) - TG-0.1 - TG-X.Zenables: # Optional: Circulars this one enables - TG-A.B---2Editorial fields only. The block above is what a circular author writes. Each page also
carries platform frontmatter — project, visibility, status, content_type, brand,
sidebar_category and sidebar.order — which the /new-page skill sets and authors do not
hand-edit.
3status and circular_status are different fields. status is the platform publish gate
(working or published) and governs whether a page is built at all. circular_status is the
editorial state (Draft, Completed, Planned) shown in the metadata table. A page can be
status: published and circular_status: Draft at the same time — that is the normal state for
a circular out for consultation.
4Note on badge: See Section 3.3 for stability classification definitions. Note on publication version: The version field reflects the public publication version, not the internal pipeline draft count. Pipeline drafts (e.g., draft-v4, draft-v6) are production artefacts only, and the publication version is confirmed by the Secretariat before a circular moves to Completed status.
4.2 Metadata Display Block
Section titled “4.2 Metadata Display Block”1The site renders a metadata table automatically from YAML frontmatter (circular_id, version, badge, circular_status, last_updated). Authors do not hand-write the display block in the markdown body.
2Required frontmatter fields for the metadata table:
circular_id: TG-X.Yversion: "0.1.0"badge: Applied # Core | Applied | Emergingcircular_status: Draft # Draft | Completed | Plannedlast_updated: Month Year # e.g. May 20263Note on Last Updated: Manually maintained by the author at publication time.
4.3 Standard Section Structure
Section titled “4.3 Standard Section Structure”Standard Circular Template (Sections 1—4, 6)
Section titled “Standard Circular Template (Sections 1—4, 6)”# Circular Title
## 1. Outcome[What readers will achieve -- 1-2 paragraphs]
## 2. Requirements[Prerequisites with hyperlinks to other circulars]
## 3. Guidance Material### 3.1 [Topic]### 3.2 [Topic]...[Core methodology -- bulk of content]

References## Appendixes2Note: This template has not yet been validated against compiled Section 5 drafts. Authors should cross-check against TG-5.x working drafts when available.
Front Matter Template (Section 0)
Section titled “Front Matter Template (Section 0)”1Section 0 circulars have unique structures appropriate to their purpose:
- 20.1 General Introduction: Extended conceptual content with figures
- 30.5 Navigating: Primarily visual/tabular (dependency graphs, pathways)
- 40.6 Glossary: Definition list format organised alphabetically
- 50.7 QA Principles: Reference document format with standards citations
6Any Section 0 circular not listed above follows the Standard Circular Template.
4.4 Section Content Guidelines

| References | Citations | Footnote format for in-text citations; numbered list acceptable when no in-text anchors present |
4.5 Section Scope Tests
Section titled “4.5 Section Scope Tests”1Each section’s scope is stated in Section 3.1. The tests below say what that scope means when an author is deciding whether a passage belongs in the circular they are writing. They were derived from the Section 1 review of September 2026 and the Section 3 review that followed it, both of which found method distributed across sections that had no rule to test it against.
| Section | The circular gives | It cross-refers for |
|---|---|---|
| 1 Decision-Making | Which accounts and indicators bear on a decision, how to read them, how to present them | How they are built (2, 3, 4, 6) |
| 2 Indicators | The indicator’s definition, normalisation and aggregation | The account it is derived from (3) |
| 3 Accounts Compilation | The account table — its rows, columns and accounting identities — and the compilation procedure that populates it | Sector-specific method (6), measurement protocol and data source (4), the indicator derived from it (2), the decision that uses it (1) |
| 4 Data Methods | The variable delivered to an account: definition, source, unit, coverage, reference value, uncertainty, quality tier | The account the variable enters (3) |
| 5 Case Studies | What one country did and what others can act on | Every method it applied |
| 6 Thematic Methods | Method specific to one ecosystem, sector, asset class or intervention class | The generic account structure it populates (3), the measurement protocol (4), the indicator derived from it (2), and readiness and sequencing (0.8) |
2Two consequences are worth stating explicitly, because both have been breached in practice:
- 3A Section 4 worked example may show a variable being produced and quality-assured; it should not show an account being balanced. Balancing an account is Section 3 work, and so is the valuation choice that populates a monetary cell.
- 4Section 3 keeps what generalises across assets — the boundary decision, the classification into SEEA asset categories, the account rows and identities. Sector-specific method belongs in Section 6, named by circular. Where a Section 3 circular is the only place a method appears, it moves rather than being deleted.
- 5Section 6 is not only ecosystems and industries. The row above was widened in September 2026 after a read-across of the whole section found four circulars that the earlier wording did not admit: TG-6.11 treats an asset class, TG-6.12 a residual-flow class, TG-6.13 a spatial interface between two accounting domains, and TG-6.15 an intervention class. All four give method specific to their subject and cross-refer for the generic structure, which is the operative half of the test; the earlier wording named only ecosystems and sectors and so excluded them by accident rather than by decision.
- 6Where two Section 6 circulars can record the same entry, one of them owns it and says so. The read-across found four such overlaps — submerged artificial structures, the coastal protection service, blue carbon pricing, and nutrient loads to coastal waters — each recorded in two places without a rule. A Section 6 circular that shares an account entry with another must name the owner in its boundary statement or at the point of overlap.
7Every circular in Sections 1 to 4 and 6 should carry a short boundary statement, in its :::note[Framework Position] block or immediately after it, naming which account or decision it owns and which circulars own the method it excludes. TG-3.9 is the model.
5. Page Length Guidance
Section titled “5. Page Length Guidance”1Page counts refer to rendered PDF A4 pages at approximately 500 words per page. These are guidance targets, not enforced limits.
| Section | Typical Length | Notes |
|---|---|---|
| Section 0 (Front Matter) | Variable | 0.1 and 0.5 are longer by design |
| Section 1 (Decision-Making) | 4—6 pages | Conceptual + examples |
| Section 2 (Indicators) | ~4 pages | Methods focus |
| Section 3 (Accounts Compilation) | 6—8 pages | Detailed methodology |
| Section 4 (Data Methods) | 4—6 pages | Practical procedures |
| Section 5 (Case Studies) | 8—12 pages | Full treatment |
| Section 6 (Thematic Methods) | 6—8 pages | Ecosystem/sector deep-dives |
6. Version and Revision Policy
Section titled “6. Version and Revision Policy”6.1 Version Numbering
Section titled “6.1 Version Numbering”1Format: v0.[Major].[Minor] — the leading 0. marks the consultation edition, which is not adopted guidance
- 2Major version (v0.1.0 → v0.2.0): Substantive content changes — new standards incorporated, significant methodological corrections, structural reorganisation
- 3Minor version (v0.1.0 → v0.1.1): Editorial improvements — clarifications, added examples, typographic corrections, updated cross-references
6.2 Revision Policy
Section titled “6.2 Revision Policy”- 1All circulars undergo annual review to assess whether updates are needed
- 2Core circulars are updated only when underlying standards change
- 3Applied and Emerging circulars may be updated based on implementation experience
6.3 Superseded Versions
Section titled “6.3 Superseded Versions”1Superseded versions will be archived, with the URL scheme to be confirmed. The current version always appears at the canonical URL.
7. Production Process
Section titled “7. Production Process”7.1 Circular Development Workflow
Section titled “7.1 Circular Development Workflow”1Table 7.1.1 below summarises the full per-circular review lifecycle for the Second Edition.
| Phase | Description |
|---|---|
| Triage | Issues raised against each draft are triaged (immediate-fix, verification-needed, user-input-needed) and recorded in the draft’s issue inventory. |
| Draft compilation | A new draft is compiled applying all closed/fixed resolutions; each draft has a paired revision log. |
| Director review | The draft undergoes a director-level quality gate; findings logged in director-review-vN.md. |
| Director fixes | Actionable director-review findings are applied to the draft. |
| Secretariat review | New issues raised are logged in secretariat-review-vN.md and feed the next triage cycle. |
| Publication | Approved circular published with DOI assignment. |
2Internal production uses an extended triage / director-review / Secretariat-review pipeline. Details are documented in project tooling and are not part of this public-facing circular.
7.2 Publication Cadence
Section titled “7.2 Publication Cadence”1Circulars are published on a monthly cadence following Secretariat review, with publication frequency varying by batch. Priority circulars may be fast-tracked, and updates to existing circulars are published as needed.
8. Dependency and Prerequisites
Section titled “8. Dependency and Prerequisites”8.1 Dependency Tracking
Section titled “8.1 Dependency Tracking”1Dependencies are tracked in two ways:
- 2YAML frontmatter:
prerequisitesandenablesfields in each circular - 3Prose requirements section: Human-readable list with hyperlinks (Section 2 of each circular)
4The prerequisites field and the prose Requirements section must be kept synchronised. The enables field is machine-readable only and has no prescribed prose counterpart.
8.2 Dependency Principles
Section titled “8.2 Dependency Principles”| Principle | Guidance |
|---|---|
| Explicit prerequisites | Only list circulars that are genuinely required. |
| Minimal dependencies | Avoid unnecessary prerequisites that create barriers. |
| Bidirectional tracking | When adding a prerequisite, update the enables field of the prerequisite circular. |
| Foundational circulars | Explicit listing of foundational circulars (e.g., TG-0.1) is recommended even when transitively covered; omit only for mid-chain intermediaries. |
8.3 Dependency Graph
Section titled “8.3 Dependency Graph”1See TG-0.5 Navigating the Technical Guidance for the visual dependency graph.
9. Cross-Cutting Themes
Section titled “9. Cross-Cutting Themes”1Cross-cutting themes are catalogued in TG-0.5 Navigating the Technical Guidance. Authors should ensure consistency with the treatments described there. Key threads include:
| Theme | Thread |

| Uncertainty | 0.7 (QA principles) → relevant methods circulars |
| Governance | 1.1—1.2 (decision-making entry points) → 3.7 (governance accounts) → 5.x (all case studies) |
| Traditional knowledge | 0.1 (conceptual framing) → 3.6 (traditional knowledge accounts) → 5.x (case studies) |
| Sub-national applicability | 3.11 (sub-national accounts) → 5.x (case studies, where applicable) |
| Ocean economy | 1.0 (terms, and what an account can certify) → 3.3 (boundary and account) → 2.5 (indicators) → 1.1 / 1.10 (use) → 5.x (case studies) |
