This session brings together major Saudi masterplanned developments that are applying the LEED for Cities and Communities framework to drive measurable sustainability outcomes at community scale. As Saudi Arabia advances ambitious transformation goals under Vision 2030, giga-scale developments are using LEED not simply as a certification target, but as a structured governance and performance framework guiding infrastructure investment, renewable energy integration, environmental protection, and long-term resilience planning. Moderated by Vatsal Bhatt, this panel will explore how large-scale Saudi projects are embedding LEED requirements into early master planning, policy alignment, and infrastructure design to ensure accountability and measurable impact. Speakers will share implementation lessons from certified and pursuing LEED community projects, highlighting how certification has influenced capital decisions, stakeholder coordination, performance monitoring systems, and cross-sector collaboration. The discussion will examine how LEED for Cities and Communities supports transparency, risk reduction, and long-term operational performance while delivering third-party validated environmental and social outcomes. Attendees will gain practical insights into applying LEED at masterplan scale and understanding its role in shaping sustainable national development through structured, performance-driven investment.
