From GPM-b™ to CSPP™
The credential matures with the profession

Effective June 5

On June 5, the Green Project Manager – Basic (GPM-b™) becomes the Certified Sustainable Project Professional (CSPP™).

The GPM-b™ was established in 2013 as the first sustainability certification for project professionals.GPM btoCSSP Thousands of practitioners adopted it and applied its principles across industries, geographies, and project types. It created a foundation where none existed and moved sustainability from concept into execution within the project lifecycle.

The CSPP™ reflects how the profession has matured. Sustainability is now embedded across governance, planning, decision-making, and delivery. It operates as a knowledge area that intersects with cost, risk, schedule, quality, and value realization. The scope spans labor and working conditions, community impacts, emissions, resource use, compliance, ethics, and adaptive governance. These domains influence outcomes, performance, and long-term project viability.

The certification is built for practitioners responsible for delivering outcomes under real constraints. It focuses on tools, methods, and decision frameworks that apply within active projects and integrate into existing delivery models without requiring parallel systems or separate processes. It aligns with the PMI Gold Standard Certification format, strengthening its structure and recognition across the global project management community.

Backed by two global leaders

The CSPP™ is the only certification backed by two global leaders: PMI, the world’s leading professional organization for project management, and GPM, the global leader in Sustainable Project Management™ practice.

What this means for current holders

Opt in to upgrade

Current GPM-b™ holders may opt in at no cost to upgrade to the CSPP™. No exam and no additional training required.

Or retain the GPM-b™

Holders may also choose to retain the GPM-b™ designation through its current validity period. The work behind either credential reflects the same foundation and is recognized within a framework that reflects how sustainability operates in modern project practice.

Why this matters

Projects are the point of execution for strategy, policy, and investment. Embedding sustainability at that level is how organizations move from stated intent to measurable outcomes. The CSPP™ is how the profession makes that commitment operational.
