On April 28, the U.S. Green Building Council (USGBC) introduced LEED v5 (leadership in energy and environmental design), the latest version of its green building certification program. Shaped by feedback from thousands of industry professionals, LEED v5 tackles key sustainability challenges, emphasizing decarbonization, human health and resilience.
Decarbonization now represents 50% of the total certification score, with the new system guiding projects toward ultra-low-carbon buildings through life cycle emissions strategies—from operations to transportation. All projects must produce an operational carbon projection and adopt a long-term decarbonization plan.
LEED v5 also enhances its focus on occupant well-being and community health, aligning with growing global demand for healthier, more transparent, and sustainable buildings.
