GPM PSM3™
Portfolio, Program & Project Sustainability Model
The most comprehensive sustainability maturity assessment available for project-driven organizations
Most organizations know their ESG commitments on paper. Fewer know whether their project portfolio is actually delivering on them. PSM3™ closes that gap. It is an independent, third-party assessment that examines how sustainability is embedded across your entire portfolio, program, and project management practice — and produces a data-driven benchmark that tells you exactly where you are, what it costs you to stay there, and what it takes to advance.
PSM3™ assesses performance across more than 40 domains aligned with the GRI 2021 Framework, integrated with the PMI-GPM P5™ Standard across four dimensions: People, Planet, Prosperity, and Practice. Independent GPM assessors conduct the evaluation across all departments, producing quantitative scores, qualitative findings, and a structured 18–24 month improvement roadmap. The output is shareable with senior leaders, investors, and external stakeholders — and is structured to feed directly into ESG disclosures.
You cannot disclose what you cannot measure. PSM3™ gives you the measurement — grounded in practice, verified by independent experts, and structured for audit.
The PSM3™ Maturity Scale
PSM3™ places your organization on a six-level scale. Most organizations are surprised by where they land. The assessment identifies not just the level but the specific practices, governance structures, and accountability gaps driving it.

What the Assessment Delivers
|
Independent Third-Party Assessment
Conducted by certified GPM assessors across all departments — not a self-assessment survey. Independent findings carry weight with auditors, investors, and regulators that internal reporting cannot.
|
|
Quantitative and Qualitative Benchmark Data
Domain-level scores across People, Planet, Prosperity, and Practice, plus narrative findings on strengths and gaps. Data is structured for direct input into ESG disclosures aligned with GRI 2021 and the PMI-GPM P5™ Standard.
|
|
An 18–24 Month Improvement Roadmap
Not just a score — a structured development path with clear, achievable maturity goals. Each recommendation is tied to specific practices, governance changes, or capability investments with defined outcomes.
|
|
Stakeholder-Ready Output
The PSM3™ report is structured for sharing with boards, investors, CSOs, and external auditors. It provides the transparency investors need and the evidence regulators increasingly require under CSRD and CSDDD.
|
|
ESG Disclosure Alignment
PSM3™ findings connect directly to your GRI materiality assessment, CSRD double materiality obligations, and ISSB/IFRS S2 reporting. The assessment gives your sustainability team the project-level evidence base that organizational-level reports typically lack.
|
Is Your Organization Ready for What’s Coming?
Regulatory pressure on sustainability disclosure is tightening. Investor scrutiny of ESG claims is increasing. Supply chain due diligence is becoming a legal obligation in major markets. The organizations that will manage this well are the ones that understand their current position clearly — not the ones with the most polished sustainability narrative.
Ask your team these questions honestly:
| Are environmental and social impacts systematically assessed in every project at authorization? |
| Do your ESG reports contain project-level evidence, or organizational estimates? |
| Can you quantify the sustainability performance of your portfolio with data an auditor would accept? |
| Does your sustainability commitment extend beyond your own operations into your supply chains? |
| Do your project leaders have the governance tools and accountability structures to deliver on ESG targets? |
If the honest answer to any of these is no — or uncertain — PSM3™ tells you what is actually in place, what is missing, and what to address first.

Linking ESG strategy to verifiable project-level performance. PSM3™ provides the data to close the gap between sustainability commitments and board-level reporting.

PSM3™ does not tell you what you want to hear. It tells you where you are — with the specificity and independence that gives the findings value to the people who matter most: your board, your investors, and your regulators.
