Research demonstrates that LEED certification, developed by the U.S. Green Building Council, is essential in advancing sustainable building practices, reducing environmental impact, and enhancing occupant health.
LEED has experienced significant global expansion, with over 195,000 certified buildings across 186 countries as of March 11, 2025, notably in regions such as North America and East Asia & Pacific.
The evidence suggests that LEED influences buildings by decreasing operating costs and enhancing efficiency, while globally, it contributes to reducing carbon emissions and resource consumption.
The current status indicates robust adoption in North America, with approximately 60,000 buildings, in East Asia and the Pacific, with about 50,000 buildings, and in South Asia, with roughly 20,000 buildings. Other regions, such as Sub-Saharan Africa, exhibit varying levels of adoption, with around 5,000 buildings.
Historical Evolution
Leadership in Energy and Environmental Design (LEED), initiated by the U.S. Green Building Council (USGBC) in 1993, introduced its inaugural rating system in 1998. The Operations and Maintenance (O+M) version, originally known as LEED for Existing Buildings, was launched in 2004 to promote the sustainable management of existing structures. This version underwent updates in 2009, 2013, and 2019, with LEED v4.1 focusing on data-driven performance and mandating recertification every five years. By 2025, LEED has certified over 195,000 buildings across 186 countries, underscoring its global impact and reach. LEED - Wikipedia.
The Importance of LEED Certification
LEED certification is crucial because buildings are responsible for approximately one-third of global CO2 emissions and substantial resource consumption, surpassing the Earth's ability to regenerate. This certification decreases operating costs by 8–9%, enhances property value by up to 7.5%, and promotes occupant health with improved indoor air quality, making it indispensable for both sustainability and economic advantages.
