Introducing the Emerging ChangeMaker Retreat Cohort

Meet the participants of the Holcim Foundation Emerging ChangeMaker (ECM) Retreat 2025

The Emerging ChangeMaker Retreat brought together a diverse group of early-career professionals from around the world to explore leadership, foresight, and systemic transformation in the built environment.

Last updated: December 12, 2025 Zurich, Switzerland

Over the course of the retreat, participants engaged with experts from leading organisations, collaborated in workshops and scenario exercises, and examined how interdependent actors can shape more sustainable and resilient futures.

They took part in discussions, site-based learning, and cross-disciplinary exchanges that deepened their understanding of strategic foresight, systems thinking, and impactful leadership. The retreat provided a platform for shared enquiry and collective imagination, equipping the cohort to apply their insights within their own contexts and future practice.
