What a GPM360° certificate does for you
It ends the conversation that starts with "prove it".
When a rating agency cites ESG factors in a negative action, when an institutional investor asks for evidence that a flagship project delivers on stated commitments, or when a disclosure under GRI or ISSB needs project-level substantiation, "we believe so" is a weak answer. "An independent third party has verified it, and here is the report" is the answer GPM360° produces.
Evidence in the language rating agencies use
Findings are mapped to the published methodology factors of Moody's ESG Credit Impact, S&P Global ESG Evaluations, Fitch ESG Relevance, MSCI ESG and Sustainalytics, so investor relations has citable evidence for analyst dialogue.
Disclosure-ready project data
The verification report is structured to support disclosures under GRI, ISSB S1 and S2, CSRD and the IFC Performance Standards. Project-level data flows into corporate sustainability reporting without re-work.
A certificate with one meaning
Certification requires every material impact to reach baseline or better after proposed responses. Strong scores in one area cannot offset degradation in another. The certificate states that no known harm remains unmitigated.
Risks surfaced before they become liabilities
Environmental, social, governance and resilience risks are identified against the structured criteria of the chosen model, with proposed responses, while there is still time to act.
One account of the project, shared by every team
The assessment brings project, sustainability, finance, governance and investor relations teams to a single evidence-based account of performance. The certificate becomes an institutional record rather than one team's deliverable.
Three assessments, one discipline
Choose the model by the question in front of you.
The three models share GPM's assessment discipline: evidence-based scoring, the certification floor, project-level focus and structural independence. Each answers a different question for a different audience. They are alternatives rather than tiers, and an organization can move between them as the need changes.
Model 1
Investor Confidence
P5 for Business v2.0 · 28 cross-sector indicators · lifecycle-aware
"Can investors trust that this project is well run, resilient and durable under uncertainty?"
Assesses: the whole picture: business and financial profile, resilience, governance, conduct integrity and sustainability, across 28 indicators aligned with the full methodologies of the five rating and ESG agencies, at the right stage of the project's life.
Gives you: an independent signal of project resilience and quality in the factor language credit and ESG agencies use, built to strengthen investor confidence and defend against downgrade.
For: issuers, sponsors and government-linked companies facing investor scrutiny or downgrade risk; CFOs, treasurers and boards carrying capital and rating risk.
Model 2
ESG Alignment
P5 for Business v2.0 · 71 elements × five raters + Tier 1 · 524 mapped points
"How does this project align with the ESG criteria the rating world uses?"
Assesses: the project against the ESG frameworks of Moody's, S&P Global, MSCI, Fitch and Sustainalytics, plus the Tier 1 foundation standards: IFC Performance Standards, ISSB S1 and S2, GRI, TCFD and the Equator Principles. 524 traceable alignment points.
Gives you: an ESG-specific view in the raters' own language, showing where the project's evidence corresponds to what each framework assesses, with every claim auditable to a specific criterion.
For: heads of sustainability and ESG facing rater scrutiny, investor relations and disclosure teams, and organizations preparing for ESG due diligence, green finance or index inclusion.
Model 3
Sustainability Assessment
PMI GPM P5 Standard, Version 4.0 · 52 elements · three domains, eleven subcategories
"Is this project making things better, worse or neutral across People, Planet and Prosperity?"
Assesses: the project's sustainability impacts across the 52 elements of the P5 Standard, scored 1 to 5 against baseline with the P5 Impact Analysis. Scores aggregate to subcategory, domain and overall, and feed a Sustainability Management Plan.
Gives you: GPM's established project-level sustainability assessment, applied by trained assessors, producing a defensible score and a managed path to improve it. The foundation the model family is built on.
For: Chief Sustainability Officers, project teams and sponsors who want a credible sustainability score for a project and a plan behind it.
How the three relate
Model 3 is the sustainability assessment on the P5 Standard, Version 4.0. Models 1 and 2 are built on the newer P5 for Business v2.0 and extend the assessment outward to the criteria of the rating and ESG agencies: Model 2 through the ESG lens, Model 1 through the full credit and resilience picture. Model 2 is, in effect, the sustainability dimension of Model 1 expanded into rater-specific detail; Model 1 places that view inside the broader picture an investor weighs.
Certify at any stage
Evidence at the moment the disclosure or the investor needs it.
A GPM360° verification is anchored to a specific project stage, so a project can be certified when its disclosure or investor commitment requires evidence rather than only at completion. All three models support this.
Planned
Verification based on project design, business case and intended outcomes, establishing accountability and stakeholder evidence before work begins.
In progress
Verification of performance during execution. The most common stage for investor-facing certification of multi-year capital projects.
Completed
Verification of realized outcomes after completion: the strongest evidence base for ESG reporting, benefits realization claims and investor communication about flagship projects.
How verification works
An assessment team, GPM validation, three steps.
Each verification is conducted by an assessment team led by a registered GPM360° Lead Assessor. The team's findings are then validated by GPM before any certificate is issued, so the organization that wrote the standards signs off on every result. The process is documentary and interview-based; site visits are available as a paid addition for clients who require them. The same structure applies to all three models.
1. Scoping and materiality
The assessment team, led by the Lead Assessor, works with the project team to identify which elements of the chosen model are material to the project's outcomes and practices. Materiality is determined jointly, documented, and reviewed by GPM at validation, which prevents convenient omission of difficult areas.
2. Evidence review and verification
Project plans, contractor agreements, monitoring data, regulatory filings, environmental and social studies and stakeholder records are reviewed against each material element. Structured interviews with the project team, the sponsor and, where relevant, external stakeholders test claims against evidence. Each material impact is scored 1 to 5 before and after proposed responses.
3. GPM validation and certification
GPM validates the assessment team's findings, evidence and scoring. Certification is issued only if every material impact scores at Baseline (3) or higher after proposed responses. The certificate, executive summary and framework alignment map are then released.
The scale and the certification floor
Every material impact at baseline or better. No averaging.
A GPM360° certificate carries one meaning whichever model was applied: every material impact identified for the project has been independently verified to meet or exceed baseline after proposed responses, with no material area in degradation. This absolute standard is what separates a GPM360° certificate from rating products that compress findings into a weighted score.
5
Net positive enhancement
The impact significantly improves the project's outcomes.
4
Net improvement
The impact improves the project's outcomes.
3
Baseline: the certification floor
The project is neither materially improving nor degrading baseline conditions.
2
Degradation
Any material impact at this score after proposed responses prevents certification.
1
Severe degradation
Any material impact at this score after proposed responses prevents certification.

Before you choose, understand your context
The same score means something different on a simple project and a complex one.
A GPM360° assessment is read in context. An indicator score on a well-understood project means something different from the same score on a project operating under shifting regulation, contested supply chains or cascading risk. The GPM Project Complexity Rating is a free, structured tool that produces a context profile across twelve indicators of internal complexity, external complexity and risk coupling.
The rating describes the terrain rather than judging the project, so whichever model is chosen its findings can be read with the right posture. It is also useful on its own for sponsor and board conversations about what the project faces.

Start the free rating toolWhy a GPM360° certificate holds up
Six properties an investor or analyst can test.
Project-level
Corporate ESG ratings cannot answer a project-level investor question. GPM360° is built for the unit of work investors and rating agencies scrutinise, with three lenses for the question that matters most.
An absolute standard
Certification requires every material impact at baseline or higher. There is no averaging, no offsetting and no medal hierarchy, in any of the three models.
Mapped to the frameworks that matter
Findings cross-reference the IFC Performance Standards, ISSB S1 and S2, the GRI Sector Standards and Equator Principles 4, extended in Models 1 and 2 to the full methodologies of the five major rating and ESG agencies.
Structurally independent
An assessment team led by a Lead Assessor does the work, and GPM validates it before certification. A certificate is neither a self-declaration nor a single-author opinion.
Verifiable
Every certificate carries a unique identifier, and GPM confirms its authenticity to any investor, analyst, journalist or regulator who asks.
Run by the organization that wrote the standards
GPM360° certifies against standards GPM wrote: the P5 Standard, now published with PMI as Version 4.0, and P5 for Business v2.0. No other organization in the world can certify a project against them. GPM360° has given projects defensible standing in front of investors, regulators and rating agencies since 2015.
GPM360° Assessors
Registered, supervised, and kept current.
GPM trains and registers the assessors who form GPM360° assessment teams, and the Lead Assessors who lead them, inside their own organizations or as independent practitioners. Registration follows structured training and supervised engagements alongside registered GPM assessors. Each model has its own assessor track, so an assessor may be registered for one, two or all three.
To stay registered, an assessor must lead or co-lead at least one verification in every sixteen-month period, which keeps their familiarity with the standards, the disclosure frameworks and the method current.

Questions we are asked
Before you request a briefing.
Is GPM360° a rating or a ranking?
It is an independent verification of one project. There is no peer ranking and no weighted score. A certificate is issued only when every material impact is at baseline or better after proposed responses.
Which model should we choose?
By the question you need answered. Investor or downgrade risk points to Model 1. Rater scrutiny, ESG due diligence, green finance or index inclusion points to Model 2. A sustainability score for a project with a plan to improve it points to Model 3. The briefing settles it.
What is involved for our team?
Providing project documentation and taking part in structured interviews. The process is documentary and interview-based; site visits are available as a paid addition where required.
Can a project be certified before it is finished?
Yes. Verification is anchored to a stage: planned, in progress or completed. In-progress certification is the most common for multi-year capital projects.
How does a third party confirm a certificate?
Every certificate carries a unique identifier. A third party sends it to GPM, and GPM confirms whether the certificate is genuine, which model was applied and when it was issued.
How does GPM360° relate to PSM3™?
PSM3™ measures the maturity of the organization that delivers projects. GPM360° certifies a single project. Organizations often use PSM3™ to raise the share of projects that can reach the GPM360° floor.
