Implementation Readiness Assessment

This Circular provides a country readiness self-assessment framework for launching or scaling ocean accounts. It guides countries through evaluating their institutional, data, and human capacity prerequisites, and outlines phased implementation pathways appropriate to different starting conditions. After reading this Circular, national statistical offices, ocean agencies, and inter-ministerial coordination bodies will be able to diagnose their current readiness level, identify priority gaps, design a sequenced implementation plan, and mobilise the institutional arrangements necessary to sustain ocean accounting as a regular statistical programme.

How account outputs then reach the planning cycle is TG-1.10 OA and National Planning Integration; the operational design of data-coordination committees is TG-4.7 National Data Coordination Architectures.

Essential prerequisites:

• TG-0.1 General Introduction to Ocean Accounts — for the conceptual framework and the nested superset structure of economy, society, and environment

Helpful background:

• TG-0.4 Structure and Focus — for the overall structure of the Technical Guidance and dependency relationships between circulars
• TG-0.5 Navigating the Technical Guidance — for audience pathways that help prioritise which accounts to compile first

3.1 Country Readiness Self-Assessment Framework

The readiness assessment covers four dimensions. Legal and regulatory environment is embedded as a sub-dimension of institutional capacity, because legal barriers to data sharing operate differently from coordination weakness and must be diagnosed separately:

3.1.2 Readiness scoring rubric

Each dimension is scored on a four-level maturity scale aligned to SEEA implementation progression. The levels are cumulative: achieving a higher level implies that the requirements of lower levels have also been met. Where sub-element profiles are mixed, score to the highest level for which all criteria are met and record partial achievement of higher-level criteria as evidence for gap analysis in Section 3.1.3 Step 3.

Institutional capacity scoring:

Data infrastructure scoring:

Human skills scoring:

Policy demand scoring:

3.1.3 Conducting the assessment

The self-assessment should be conducted by a small team that includes representatives from the national statistical office, the lead ocean or environment agency, at least one major data provider, and where possible a policy user from a planning or finance ministry. The assessment can be completed in a structured workshop of one to two days, following these steps:

Countries are encouraged to share their assessments through the GOAP network to support peer learning.

3.2 Phased Implementation Pathway

The following three-phase pathway is recommended as a general model. Countries should adapt it to their specific circumstances. The phases are not rigidly sequential, and countries may pursue elements of later phases in parallel where capacity permits. Figure 0.8.1 illustrates how a country’s SNA and spatial capacity profile routes it to an entry point, and how the phase at which it starts the Foundation—Expansion—Integration pathway is set separately by its overall readiness level.

Phase 2: Expansion

Phase 2 begins at Phase 1 completion, with elements that may be initiated in parallel where capacity permits. Key activities:

• Additional account types: Extend to ecosystem condition accounts, physical ecosystem service flow accounts, and asset accounts. The sequence should be guided by policy demand and data availability, drawing on the requirements matrix in Section 3.3.
• Monetary valuation: Initiate monetary valuation of ecosystem services where appropriate, beginning with services where market-based methods can be applied.
• Indicator derivation: Develop indicators from the accounts in consultation with policy users.
• Institutional consolidation: Formalise data-sharing agreements. Integrate ocean accounting into the NSDS or equivalent. Establish quality assurance procedures aligned with TG-0.7.

Countries with existing SEEA implementation experience for land, water, energy, or forest accounts will often find that their readiness levels are higher across multiple dimensions. Institutional arrangements, data infrastructure, and human skills developed for those accounts are substantially transferable to ocean accounting.

3.3 Implementation Requirements Matrix

The matrix below maps institutional capacity, data infrastructure, and human skills needed across major ocean account types. Reading down a column identifies the full set of prerequisites for a particular account type. Reading across a row indicates how requirements scale across types for planning purposes.

3.3.1 Institutional capacity requirements

Lead-agency entries in the first row are illustrative, whilst country governance choices in Section 3.5.2 take precedence.

The lead agency should have both the institutional authority to convene data-contributing agencies and a clear mandate to manage or report on the relevant resource or ecosystem. Where no single agency holds both, a joint coordination mechanism is appropriate (see Section 3.5.2).

3.3.2 Data infrastructure requirements

3.3.3 Human skills requirements

3.3.4 Using the requirements matrix

1. Identify target accounts: Based on the implementation pathway (Section 3.2) and policy priorities, identify which account types will be compiled in each phase.
2. Read requirements: For each target account type, read down the relevant column across all three requirement tables to identify the full set of prerequisites.
3. Compare to readiness assessment: Map identified requirements against the country’s current readiness levels. Where requirements exceed current capacity, these represent gaps to be addressed.
4. Sequence investment: Prioritise requirements shared across multiple account types (e.g., spatial framework, inter-agency coordination) as foundational investments that enable multiple downstream products.

Requirements become progressively more demanding moving left to right across the matrix. Ocean economic accounts build substantially on existing SNA infrastructure. Ecosystem accounts require environmental science and geospatial capabilities. Social and governance accounts add survey and community engagement capabilities.

3.4 Human Capacity Requirements and Team Composition

3.4.1 Core team structure

Sustained ocean accounting requires a dedicated core team combining expertise across multiple disciplines. The following structure provides a general model for countries at Phase 2 or later:

During Phase 1, a smaller team of two to three staff may be sufficient, provided they have access to specialist advice from other agencies or international partners. The programme coordinator role matters from the outset, as the primary challenge in Phase 1 is institutional coordination rather than technical compilation.

3.4.2 Extended expertise network

Beyond the core team, ocean accounting requires access to specialised expertise distributed across multiple agencies and institutions:

Countries should map existing expertise early in the implementation process and develop formal or informal mechanisms (secondments, advisory panels, memoranda of understanding) to access it on a sustained basis.

3.4.3 Capacity building strategy

A systematic approach to building and sustaining human capacity should address three time horizons:

Short-term: Targeted training for the core team in SEEA concepts, ocean accounting methods, and relevant tools, combined where possible with practical application to real data through mentored pilot compilation exercises.

Medium-term: Deepening expertise through peer exchanges with more experienced countries and participation in international expert networks. Formal recognition of ocean accounting competencies within institutional human resource frameworks helps retain skilled staff.

The coordination arrangement is the first structural decision a country makes when standing up an ocean accounting programme, and it is expensive to reverse. This subsection is normative for the publication. TG-4.7 National Data Coordination Architectures Section 3.1 covers the operational design of the resulting committee — mandate content, membership seniority, relationship to existing statistics committees — and TG-1.10 OA and National Planning Integration covers how its outputs reach the planning cycle.

Arrangements observed in environmental-economic accounting programmes vary on two independent axes, and presenting them as a single list of models obscures that the two can be combined:

Table 3.5.1: Coordination arrangements by mandate holder

Table 3.5.2: Instruments that carry the mandate

Most working arrangements combine both axes. A common and effective configuration is a dedicated unit in the NSO for compilation, bilateral MOUs for data access, and a cabinet-mandated inter-ministerial committee for strategic direction and policy engagement. Countries also migrate between configurations: beginning with MOUs and adding a unit once compilation volume justifies permanent staffing, or adding a committee layer when political visibility becomes the constraint. Such transitions should be anticipated in the founding terms of reference.

Federal and shared-jurisdiction contexts. In federal systems — Australia, India, Canada — the arrangement must operate at both sub-national and national level, with an additional inter-governmental layer to harmonise methods and consolidate data flows between jurisdictions. In Pacific island states with shared or delegated ocean data access, such as the Federated States of Micronesia, the Marshall Islands and Palau, relevant data may be reached through regional bodies or bilateral arrangements rather than domestic agency networks; countries in this position should consult the GOAP Secretariat for tailored guidance.

3.5.1.1 Reviewing and adapting the arrangement

Establishing an arrangement is not a one-time decision. Three diagnostics indicate whether it is still working:

• Meeting regularity and seniority. A declining meeting rate, or persistent delegation to staff without authority to commit, signals attrition.
• Data-delivery compliance against agreed schedules, as recorded in MOU delivery logs or data-sharing registers. Missed or delayed deliveries indicate a commitment that needs renewal or renegotiation.
• Proportion of planning-cycle entry points met on time. Systematic lateness points to a compilation-cycle misalignment rather than a coordination failure, and is addressed through the scheduling in TG-1.10 Section 3.2.

Review at the close of each national planning cycle — typically every three to five years — or when a major funding or personnel disruption occurs, such as a budget cut to the compilation agency or the departure of a key champion. A significant change in the scope of the accounting programme, such as adding new account types, should also trigger a review of whether the existing arrangement can carry it.

3.5.1.2 Champions and their sustainability

Institutional arrangements alone do not sustain ocean accounting programmes. Formal mandates, coordination bodies, and data-sharing agreements provide the structural scaffolding, but programmes depend on individuals who advocate for the accounting programme, defend its budget allocation during fiscal contractions, explain its value to sceptical colleagues, and connect technical outputs to policy debates. These individuals are champions, and their role is particularly important for ocean accounting because the field is relatively new, the outputs are unfamiliar to many planning officials, and the benefits of accounting may take several compilation cycles to become apparent.

Countries that have successfully sustained environmental-economic accounting programmes over multiple years consistently identify the presence of senior advocates — in the NSO, in the finance ministry, or in the head of government’s office — as a critical success factor. The WAVES programme emphasised that “high-level political commitment” and “champions at senior levels of government” are among the most important prerequisites for successful natural capital accounting implementation. Champions serve three distinct functions that correspond to three types of champion: political, technical, and institutional. Effective ocean accounting programmes cultivate all three types, recognising that each serves a different purpose and operates in a different institutional space.

Political champions are elected officials or senior political appointees who use their public platform and decision-making authority to advocate for ocean accounting. A minister of finance who cites ocean accounting data in budget speeches, a president or prime minister who references natural capital depletion in state-of-the-nation addresses, or a parliamentarian who calls for ocean economy reporting in legislative oversight hearings — these are political champions. Their advocacy creates the political demand signal that justifies budget allocations for compilation work and motivates agency heads to prioritise data contributions.

Identifying potential political champions requires understanding which political leaders have both an interest in ocean issues and the institutional position to influence planning processes. In many countries, the minister of finance or the head of the planning ministry is the most influential political champion because they control resource allocation decisions. In small island developing States, where the ocean economy may constitute a large share of national GDP, the head of government may take a personal interest in ocean accounting as a tool for demonstrating the country’s marine resource endowment in international forums.

In statistical, scientific, and analytical agencies, technical champions are the senior professionals who drive the methodological development and compilation quality of ocean accounts. The chief national accountant at the NSO, the chief scientist at the fisheries research institute, or the head of the marine environment division at the environment ministry — these individuals provide the technical credibility that underpins the programme’s outputs and advocate for methodological investment within their agencies.

Technical champions are essential because ocean accounting requires sustained investment in statistical infrastructure, data systems, and human capital. When the NSO faces competing demands for limited compilation resources, a chief national accountant who understands the value of environmental-economic accounting will protect the ocean accounts compilation programme from being crowded out by other priorities. When the fisheries research institute is asked to provide stock assessment data in formats compatible with asset account requirements, a chief scientist who appreciates the planning applications of the data will ensure that staff time is allocated to the task.

Agencies become institutional champions when they adopt ocean accounting as a core part of their mandate and allocate recurrent budget and staff to compilation and policy communication. An NSO that lists ocean accounts in its multi-year statistical work programme, a planning ministry that requires ocean economy data in its development plan templates, or a fisheries ministry that uses asset account data as a standard input to stock management decisions — these agencies are institutional champions. Their commitment outlasts individual personnel changes because the accounting function is embedded in organisational structures, job descriptions, and budget lines.

Building institutional champions requires demonstrating that ocean accounting serves the agency’s existing mandate rather than imposing additional work with unclear returns. For the NSO, ocean accounts extend the thematic and extended accounts portfolio that the 2025 SNA identifies as a priority, and this contributes to the agency’s core mission of measuring economic performance and well-being. For the fisheries ministry, asset accounts provide the biomass trajectory data needed for stock management decisions that the ministry is already mandated to make. For the planning ministry, ocean economy data fill an information gap in development diagnostics that the ministry recognises but currently lacks the data to address.

The most effective approach to building institutional champions is to co-design the accounting programme with potential champion agencies. This co-design should ensure that the compilation outputs address questions the agency already faces. The coordination model chosen (Section 3.5.1) should be designed to facilitate this co-design process, bringing potential institutional champions into the programme design phase rather than presenting them with a completed plan.

Sustaining champions over time requires deliberate investment in four areas:

International recognition. Champions’ domestic standing is strengthened when their country’s ocean accounting programme receives international recognition. Presenting results at UN Statistical Commission sessions, contributing to GOAP technical publications, or hosting study visits from other countries all enhance the programme’s reputation and the champion’s standing within their agency.

Embedding in institutional processes. The most durable form of champion support is to embed ocean accounting in the routine institutional processes of champion agencies — statistical work programmes, budget templates, planning guidelines, and performance indicators. Once ocean accounting data are required inputs to processes that agencies must complete regardless of individual preferences, the programme acquires institutional momentum that does not depend on any single champion’s continued advocacy.

3.5.2 Implementation readiness checklist for institutional arrangements

Countries should aim to address all items by the end of Phase 1, though items 7 and 8 may extend into Phase 2:

For how account outputs reach the planning cycle once an arrangement is in place, see TG-1.10 OA and National Planning Integration. For data coordination architectures, see TG-4.7 National Data Coordination Architectures.

3.6 Country Commitment Framework

This section provides a commitment checklist for use at the readiness assessment stage, before implementation begins. It records political endorsement, resource commitment, and accountability mechanisms as preconditions for programme launch. For guidance on embedding ocean accounts in national planning frameworks and integrating accounts into budget cycles, see TG-1.10 OA and National Planning Integration.

A country commitment framework for ocean accounting should address the following elements:

Political endorsement: A statement of commitment from an appropriate authority (minister, chief statistician, or inter-ministerial body) establishing ocean accounting as a national priority. The statement should reference the policy objectives ocean accounting will support and the institutional arrangements to be put in place.

Strategic plan integration: Inclusion of ocean accounting in the NSDS or equivalent national statistical plan. For countries without an NSDS, ocean accounting can be included in the strategic plan of the lead agency.

Resource commitment: An explicit commitment to allocate financial, human, and infrastructure resources. The commitment should distinguish between initial investment (which may draw on international technical assistance) and recurrent production costs (which should transition to domestic funding). A realistic budget estimate, benchmarked against GOAP partner country experience, should accompany the resource commitment.

Timeline and milestones: A time-bound implementation plan with clear milestones aligned to the phased pathway in Section 3.2 (e.g., “Complete data inventory by month 6 of Phase 1; publish first ecosystem extent account by end of Phase 1”).

Accountability mechanism: A designated person or body responsible for monitoring implementation progress and reporting to the coordination mechanism and senior leadership at least annually.

Countries should plan early wins: policy-relevant outputs deliverable in the early stages of the programme. Phase 1 account types (see Section 3.2.1) serve well as early wins because they are feasible with existing data and are directly relevant to common policy processes.

3.7 Scoping and Pilot Implementation: Experience from the ESCAP Programme

3.7.1 The Diagnostic Tool as a scoping instrument

The ESCAP Ocean Accounts Pilot Programme (2019) demonstrated a structured implementation methodology across five countries: China, Malaysia, Samoa, Thailand, and Vietnam, each of which established a national inter-agency working group. ESCAP also supported pilot studies in Indonesia and Vanuatu. The approach used the Diagnostic Tool for Environment Statistics as a framework for guiding a structured conversation among stakeholders to determine which accounts should be prioritised.

The Diagnostic Tool addresses two core components:

Table 3.7.1: Diagnostic Tool components for ocean accounts scoping

Pilots to date have addressed topics including the value of the ocean economy and sustainability of food supply, physical measures of regulating and maintenance services (coastal protection, carbon sequestration, water purification), ecosystem extent and change (e.g., decline in mangrove area, increase in marine protected area coverage), land-based sources of marine pollution, and resource requirements of coastal tourism. The following table illustrates the types of pilot topics selected across the ESCAP programme:

Table 3.7.2: ESCAP pilot topics and associated policy concerns

The scoping phase typically involved an independent consultant, the National Statistical Office, or a responsible government agency coordinating a detailed scoping report. Most pilots identified data availability and access as major constraints and addressed these by using publicly available data, establishing data sharing arrangements with relevant institutions, or conducting original fieldwork and socio-economic surveys. A second national workshop reviewed preliminary results, benefited from additional technical guidance, and developed messaging for a release document. The process was followed in all five ESCAP pilots, which demonstrated substantial results within an approximately six-month timeframe.

Case illustration: Vietnam ESCAP Pilot (Quang Ninh Province, 2019)

The Vietnam pilot illustrates a broader finding from the ESCAP programme: initial ocean accounts can be compiled by integrating existing data from multiple sources within a common spatial and classificatory framework, rather than requiring substantial new data collection. The scoping reports produced by each pilot country have been published by ESCAP and provide detailed documentation of the diagnostic process, data sources used, and accounts compiled.

3.7.2 Prioritising account types

Countries with limited capacity should consider extent accounts as the lowest-cost, highest-data-availability starting point: area data for major ecosystem types can typically be compiled from existing remote sensing products and protected area registries without primary data collection. The planning-use-case view of the same question is TG-1.4 OA and Sustainable Ocean Planning Table 3.2.2.

This scoping phase precedes Phase 1 of the pathway in Section 3.2 and produces the account priorities the Phase 1 work programme implements.

3.8 Investment Readiness for Ocean Finance

Readiness for ocean finance is a specific case of the country readiness this Circular addresses. A proposal fails to attract finance for much the same reasons a national accounting programme stalls: an inadequate evidence base, no counterfactual, targets that cannot be measured against a compiled account, and no commitment to compile it again. The instruments themselves are treated in TG-1.8 OA and Project-Level Finance and the multilateral project cycle in TG-1.7 OA and Multilateral Development Finance.

3.8.1 Nature-based solutions: minimum evidence

Nature-based solutions (NBS) for ocean and coastal environments represent a growing category of investable projects, but many promising NBS proposals fail to attract finance because they lack the structured evidence base that investors require. The minimum information requirements are set out below.

NBS typology for ocean contexts. Ocean-related NBS can be categorised into three broad types, each with distinct accounting requirements:

Minimum evidence requirements. For any NBS proposal to be considered investment-ready, the information summarised in Table 3.8.1 below should be available from Ocean Accounts or compilable from existing account data.

Table 3.8.1: Minimum evidence requirements for NBS investment readiness

Connecting NBS to finance instruments. Different NBS types align with different financial instruments. Restoration projects typically suit results-based payment mechanisms (including blue carbon credits and performance-based grants) because outcomes can be measured through extent and condition account changes. Protection projects align with sovereign commitments (including debt-for-nature swaps) where the maintenance of ecosystem condition is the deliverable. Sustainable management projects can support blue bonds and sustainability-linked loans where KPIs are derived from supply and use table metrics such as extraction rates relative to maximum sustainable yield. For detailed guidance on these instrument types, see TG-1.8 OA and Project-Level Finance.

• Score 0-8: Not investment-ready. Substantial gaps in evidence base and financial structuring. Requires further account compilation and capacity building before approaching investors.
• Score 9-14: Emerging readiness. Core elements are in place but important gaps remain. Targeted technical assistance can address specific weaknesses.
• Score 15-19: Investment-ready with conditions. Evidence base is substantially complete. Financial structuring may require refinement. Suitable for engagement with concessional finance providers and blended finance structures.
• Score 20-24: Fully investment-ready. Complete evidence base from Ocean Accounts, sound financial structuring, and full disclosure alignment. Suitable for engagement with commercial investors and capital markets.

Application of the scoring methodology. Project developers can use this methodology as a self-assessment tool to identify gaps in their evidence base. MDBs and development finance institutions can use it as a screening tool to prioritise technical assistance. Financial institutions can use it as part of their due diligence process to evaluate the quality of environmental evidence underpinning project proposals. Sections 3.1 and 3.3 of this Circular set the wider readiness and quality assurance context this rubric sits within.

3.8.3 Shared investment criteria

Applying common criteria across instrument types. The shared criteria are designed to be applicable regardless of the specific financial instrument being used. For blue bonds, the criteria ensure that use-of-proceeds frameworks are grounded in account data. For debt-for-nature swaps, the criteria provide the monitoring framework for conservation commitments. For results-based payment mechanisms, the criteria establish the measurement basis for performance verification. For blended finance structures, the criteria provide the common evidence base that aligns public and private investors around shared environmental objectives.

These platforms support national programmes in three ways. First, countries should use regional technical assistance to build initial compilation capacity. Regional bodies often have access to technical expertise and compilation tools that individual countries — particularly small island developing States with limited statistical capacity — cannot develop independently. Second, participate in regional peer-learning networks that enable countries at different stages of implementation to share experiences, methodological innovations, and lessons from coordination challenges. Third, use regional forums to build political support for ocean accounting by presenting national results in contexts where comparison with neighbouring countries creates incentives for continued investment.

3.9.2 Regional fisheries and ocean governance bodies

Regional fisheries management organisations (RFMOs), large marine ecosystem programmes, and regional seas conventions provide governance platforms where ocean accounting data have direct policy applications. RFMOs require stock assessment data that physical fish stock asset accounts (TG-3.1 Asset Accounts) can provide. Large marine ecosystem programmes (such as those supported by the Global Environment Facility) require integrated environmental-economic assessments that ocean accounts are designed to produce. Regional seas conventions (such as the Nairobi Convention, the Barcelona Convention, and the Noumea Convention) increasingly call for integrated marine and coastal area assessments that draw on the kinds of data ocean accounts compile.

Countries that have established ocean accounting programmes can support neighbouring countries through South-South cooperation arrangements. These arrangements — which may include secondment of technical staff, joint training programmes, and shared compilation tools — accelerate implementation in receiving countries whilst deepening the expertise of contributing countries. The coordination body should explore South-South cooperation opportunities with countries in the same region or with similar ocean economies, building networks that sustain implementation beyond the initial establishment phase.

3.9.4 Peer exchange for account-finance integration

Peer learning for account-finance integration. Countries that have successfully used Ocean Accounts to support finance mobilisation can share their experience with countries at earlier stages of implementation. Effective peer learning involves structured exchanges focused on specific aspects of the account-finance pipeline: how accounts were compiled, how they were presented to financial institutions, what investor feedback was received, and how account products were refined in response. The GOAP network provides a platform for such exchanges, and participating countries are encouraged to document their experiences in standardised formats that facilitate cross-country learning.

Regional cooperation on account compilation. For transboundary marine ecosystems (shared fisheries, migratory species corridors, large marine ecosystems), coordinated account compilation across countries strengthens the collective evidence base for regional finance proposals. Regional development banks and multilateral funds favour programmatic approaches that address transboundary challenges, and harmonised Ocean Accounts across participating countries provide the coordinated data infrastructure that such programmes require.

Knowledge exchange formats. Effective South-South exchange can take several forms:

• Technical workshops: Hands-on training in account compilation and finance application, typically hosted by a country with implementation experience
• Study tours: Visits to countries that have successfully used accounts to mobilise finance, allowing direct observation of institutional arrangements and data systems
• Twinning arrangements: Long-term partnerships between countries at different stages of implementation, with regular exchange of staff and knowledge
• Online communities of practice: Ongoing platforms for sharing templates, methodologies, and lessons learned across the GOAP network

4. Limitations and Considerations

The readiness assessment framework and phased pathway provide a general model that must be adapted to country-specific circumstances. Small island developing states may face distinctive challenges related to limited institutional capacity and data infrastructure but may also benefit from relatively simpler ocean geographies and strong policy demand. Large maritime nations may have abundant data and institutional resources but face coordination challenges across multiple agencies and levels of government.

Self-assessment inherently involves subjective judgement. Countries can mitigate that subjectivity by including diverse perspectives in the assessment team, requiring evidence to support scores, and inviting external review through GOAP peer review or technical assistance missions (see Section 3.1.3 Step 6).

This Circular draws on the methodological frameworks established by the System of Environmental-Economic Accounting — Ecosystem Accounting (SEEA EA), the Strategy for Implementing 2025 SNA and BPM7, the UN National Quality Assurance Frameworks Manual, the Global Statistical Geospatial Framework (2nd edition), and NSDS guidelines. The guidance also benefits from the practical experience of GOAP partner countries in implementing ocean accounts across diverse institutional contexts.
