ISO 53001 certification for organisations that need credible, audit-ready sustainability governance

ISO 53001 is the international standard for embedding the UN Sustainable Development Goals (SDGs) into strategy, governance, and operational decision-making. SDG Assessment provides ISO 53001 certification services in the United Kingdom for organisations that need independent assurance that sustainability is being managed as a system — with roles, controls, measurement, and evidence that can be tested.
Whether you’re responding to procurement requirements, investor scrutiny, public sector expectations, or internal audit demands, ISO 53001 certification helps you demonstrate that sustainability is governed, implemented, and continually improved — not just reported.

What ISO 53001 certification demonstrates

Certification provides assurance that your organisation has implemented a management system aligned to ISO 53001, typically including:
  • Clear governance, accountability, and leadership oversight
  • SDG-aligned policy, objectives, and decision-making controls
  • Risk and opportunity management linked to sustainability outcomes
  • Measurement, monitoring, and continual improvement
  • Documented evidence that can be sampled and verified through audit
This is especially valuable when stakeholders need confidence that sustainability claims are backed by a repeatable, auditable approach.

Who we certify

ISO 53001 certification is suited to organisations across the world that need credible sustainability assurance, including:
  • SMEs in regulated or high-impact sectors
  • Local authorities and public bodies
  • NGOs and mission-led organisations
  • Financial institutions, DFIs, and impact-focused investors
  • Corporates managing supply-chain sustainability performance

Our certification process (clear, structured, audit-led)

We run certification in a controlled sequence designed to reduce disruption and increase audit confidence.
  1. Scope & audit planning
    Confirm organisational boundaries, sites/functions, exclusions (if any), and audit approach.
  2. Stage 1 audit (system review)
    Review documented system design: governance, policy, objectives, risk controls, and measurement approach.
  3. Stage 2 audit (implementation & evidence testing)
    Verify the system is operating in practice through interviews, sampling, and evidence checks.
  4. Certification decision
    Certification is issued following successful audit completion and closure of any nonconformities.
  5. Surveillance & recertification
    Ongoing audits confirm continued conformity and continual improvement.

Frequently Ask Questions

Is ISO 53001 relevant if we already report under CSRD/ESRS, B-Corp or use GRI?

Yes. Reporting frameworks focus on disclosure. ISO 53001 focuses on the management system behind the work — governance, controls, measurement, and continual improvement. Many organisations use ISO 53001 certification to strengthen the credibility of what they report.

How long does certification take to complete?

It depends on organisational size, complexity, and readiness. After scoping, we confirm audit duration, sampling approach, and a practical timeline.

What do you audit?

We audit conformity to ISO 53001 requirements — including governance, objectives, risk management, operational controls, measurement/KPIs, and evidence that the system is implemented and effective.
