Massachusetts topped the U.S. Green Building Council’s annual ranking of states for LEED green building in 2024 after ranking No. 3 on the list in 2023, according to USGBC.
States were ranked based on the number of LEED-certified square feet per capita in the state. In 2024, Massachusetts certified 132 LEED projects, surpassing 34 million square feet, equating to 4.95 LEED-certified square feet per person. The top 10 states certified 1,437 projects and more than 414 million gross square feet under LEED.
The states following Massachusetts in the Top 10 included Illinois, New York, Washington, Maryland, California, Texas, Nevada, Colorado and Virginia. USGBC notes Washington, D.C., would have had the highest ranking with 33.3 green square feet per capita and 111 green building projects, but it is not included because it is not a state.
