Understanding LEED v5: Embodied Carbon, WBLCA & the Road Ahead

With LEED v5 becoming applicable for new project registrations from July 1, 2026, embodied carbon assessment and Whole-Building Life Cycle Assessment (WBLCA) are becoming more central within green building certification workflows. Compared to LEED v4/v4.1, the updated framework places greater focus on A1-A3 carbon quantification, EPD integration, baseline comparisons, and construction activity emissions assessment.

This webinar explores how LEED v5 changes may affect embodied carbon assessments, WBLCA workflows, material reporting, and certification requirements across building projects.

WHAT THE SESSION WILL COVER

• The evolution of WBLCA requirements from LEED v4/v4.1 to LEED v5
• The updated MRp2 prerequisite, MRc2 structure, and compliance pathways
• Baseline vs proposed building modelling approaches under LEED v5
• Project scope definition, system boundaries, lifecycle stages, and reporting requirements
• EPD integration, material data hierarchy, and handling incomplete datasets
• Embodied carbon hotspots across concrete, steel, façade systems, interiors, and MEP materials
• Structural and material optimisation strategies for reducing embodied carbon
• Common implementation, coordination, and documentation challenges across project teams
• The role of digital workflows and automation in supporting carbon analysis and LEED reporting
• What the June 30, 2026 LEED v4/v4.1 registration deadline means for future projects
