ISO 53001 harmonized structure: ten clauses applied to the SDGs (ISO/UNDP 53001)
ISO 53001 follows ISO's harmonized structure, formerly known as Annex SL: ten clauses in the same order as ISO 9001, ISO 14001 and ISO 45001. Clauses 1 to 3 set the framework; the certifiable requirements sit in clauses 4 to 10, from context of the organization to improvement, adapted to managing the SDGs.

The ten clauses and their role
| Clause | Title | Role in the system | PDCA stage |
|---|---|---|---|
| 1 | Scope | What the standard covers | Framework, not audited |
| 2 | Normative references | Documents needed to apply it | Framework, not audited |
| 3 | Terms and definitions | Common vocabulary plus SDG-specific terms | Framework, not audited |
| 4 | Context of the organization | Internal and external issues, interested parties, scope of the system | Plan |
| 5 | Leadership | Top management commitment, policy, roles | Plan |
| 6 | Planning | Risks and opportunities, objectives, planned changes | Plan |
| 7 | Support | Resources, competence, communication, documented information | Do |
| 8 | Operation | Control of the activities that carry the SDG contribution | Do |
| 9 | Performance evaluation | Monitoring, internal audit, management review | Check |
| 10 | Improvement | Nonconformity, corrective action, continual improvement | Act |
Common text and SDG-specific text
In every standard built on the harmonized structure, part of the wording is identical from one standard to the next, apart from the name of the subject. Examples include the duty to determine internal and external issues, to assign roles and authorities, to run internal audits at planned intervals and to address a nonconformity through corrective action.
ISO 53001 adds its own requirements to this base. Public information from ISO and UNDP indicates that they concern, among other things, the selection of priority SDGs, the setting of objectives and monitoring indicators, and the consideration of the SDGs in governance decisions. As in any standard built on the harmonized structure, these subject-specific requirements sit inside the common clauses 4 to 10 rather than in a separate chapter, which is why the clause titles, from context of the organization to improvement, look familiar to anyone who knows ISO 9001.
Read as a loop, not a line
Numbering suggests a straight progression. In practice the clauses feed one another. Context analysis (clause 4) informs objectives (clause 6); monitoring them (clause 9) feeds management review, whose decisions return to planning; nonconformities handled under clause 10 may call into question the scope defined at the outset. That loop is what turns a set of requirements into a system.
What the harmonized structure makes possible
- An integrated system: the same processes (management review, internal audit, control of documented information) can carry quality, environmental, health and safety and SDG requirements together.
- Certificates that read alike: a customer or buyer understands that two certificates based on the harmonized structure rest on the same management logic.
- Comparable findings: a nonconformity raised against a given clause concerns the same mechanism, whichever standard is being audited.
- Coordinated change: when ISO amends the common text, the standards concerned take it on board at their next revision.

- ISO 53001 certification: what it proves and how it is issued (ISO/UNDP 53001)ISO 53001 certification confirms, after an audit by an independent body, that an organisation's management system meets the standard's requirements for managing its contribution to the SDGs.
Frequently asked questions
What is Annex SL?
Annex SL is the former name of ISO's harmonized structure, taken from the annex of the ISO Directives where the framework was defined. It sets out a ten-clause outline, clause titles, core text and terms shared by all management system standards. ISO 53001 applies it, as do ISO 9001, ISO 14001 and ISO 45001.
Why are clauses 1 to 3 not audited?
They contain no requirements addressed to the organisation. Clause 1 describes what the standard covers, clause 2 lists normative references and clause 3 defines terms. They help interpret the requirements, but the certification audit focuses on clauses 4 to 10, where the verifiable obligations are found.
Does an ISO 9001 certified organisation already know ISO 53001?
It knows the architecture and the shared mechanisms: context, leadership, planning, internal audit, management review and corrective action. It does not know the SDG-specific requirements, which address a different subject from quality. Familiarity with the structure does not replace the assessment of those specific requirements at audit.
