Why 2025 Was a Breakthrough Year for CSE’s US Programs
The year 2025 marked one of the most successful periods in the 20-year history of the Centre for Sustainability & Excellence (CSE). Our U.S. Certified Sustainability Practitioner Programs held in February, June, and October, and throughout the fall reached record participation, stronger engagement, and outstanding feedback from professionals across key sectors.
According to our 2025 impact updates, participants valued the program’s hands-on methodology, real-world case studies, and direct applicability to their organizational Sustainability needs. From New York to Chicago and online cohorts across North America, CSE continued to empower sustainability leaders with practical tools aligned with global frameworks such as GRI, SASB, ISSB, TCFD, and emerging regulatory updates.
These achievements reflect the growing importance of sustainability skills in the U.S. workforce, and why more organizations are sending team leaders back to CSE for advanced Sustainability training.

Real-World Impact: Testimonials from US Leadership Training Participants
Nothing demonstrates our success more clearly than the words of our 2025 graduates.
Esther Ro – Section Manager/Consolidated Edison, Inc.

Esther’s experience reflects the clarity and confidence many professionals gained moving from conceptual understanding to actionable sustainability integration.

“What I liked most about the training was its practical and forward-thinking approach. The use of real-world data.
