LEED project certifications in the U.S. as of 2025, by state
As of May 2025, the number of LEED certifications in California was over higher than in Texas, the next U.S. state in the ranking. This might not be surprising for some, as the Golden State is also the most populous U.S. state. Nevertheless, some differences are still observed: Florida, for instance, has more residents than New York but less LEED certifications. Meanwhile, the District of Columbia was the U.S. territory with the highest number of certifications per capita. Note that the figures provided are cumulative - which means that the state of Washington had LEED certifications as of May 2025, a figure that also includes certificates issued in previous years.
