<h1>Decarbonization requirements under LEED v5 create a clearer pathway for near zero carbon and broader certification access.</h1> USGBC has opened LEED v5 project certification and published implementation resources - scorecards for decarbonization, quality of life, and ecological conservation; calculators; a scorecard builder; a decarbonization workbook; recertification guidance; and updated Reference Guides - to support planning and certification. LEED v5 establishes decarbonization and capital planning requirements, including minimum carbon reductions at the Platinum level, and offers crosswalks with WELL and SITES plus O+M beta examples demonstrating early adopter certifications and operational benefits.
