## Description

USGBC’s LEED certification deadlines table specifies transition dates for LEED v4 and v4.1. For most LEED v4/v4.1 commercial rating systems (BD+C, ID+C, O+M), new registrations close on 2026-06-30 and certification submissions sunset on 2032-06-30. The table also documents exceptions (e.g., some O+M recertification/interiors pathways and certain campus/volume scenarios) that allow registration beyond 2026-06-30 while retaining the 2032-06-30 sunset. This impacts project pipeline planning (which rating system a project can register under) and internal controls to ensure teams register before the applicable close date and plan submissions ahead of the sunset.
