LEED v5 and the evolving US landscape

The United States created LEED through the U.S. Green Building Council (USGBC) and remains its largest market. With over 50 million gross square metres of certified space, LEED is the de facto standard for commercial real estate sustainability in America.

LEED v5, launched in April 2025, introduces stricter carbon requirements, enhanced social equity credits, and lifecycle assessment mandates. Federal, state, and municipal incentives increasingly reward LEED certification. ISG brings international cross-certification experience — bridging LEED with Estidama, BREEAM, and GSAS knowledge from Gulf markets.
