Showcasing the expansion of green building across the U.S.
USGBC offers theÌýLEED rating systemÌýand other industry-shaping resources to aid in reducing greenhouse gas emissions in new and existing buildings. LEED is the world’s most widely used green building program, created by USGBC as a leadership standard defining best practices for healthy, high-performing green buildings.Ìý
A new record was set in 2023 for adding the most LEED-certified gross square footage (GSF) of green building space in a single year as the world saw alarming climate impacts including record-setting temperatures and storms of increasing intensity. In total, there were more than 6,000 LEED-certified commercial projects worldwide, representing 1.36 billion GSF.
* The list of states in the U.S. with certified GSF per capita includes commercial projects certified in 2023. To calculate the rankings, the commercial square footage certified in 2023 is divided by the state population, based on the 2020 U.S. census records. Washington, D.C., is not included in the rankings as it is a federal district.
