The U.S. Green Building Council (USGBC) released its annual ranking of the top 10 states for LEED. The list highlights states throughout the country that are making impactful strides in sustainable building design, construction and transformation. The per-capita list is based on 2010 U.S. Census data and includes commercial and institutional green building projects that were certified in 2014.

Collectively, 1,662 commercial and institutional projects became LEED certified within the top 10 states in 2014, representing 251.7 million square feet of real estate. Washington, D.C., which is not ranked because it is a federal district rather than a state, has the highest per-capita square footage in the country at 29.44.

The top 10 states based on per-capita square footage are Illinois (3.31), Colorado (3.15), Maryland (2.7), Virginia (2.33), Massachusetts (2.2), Hawaii (1.95), California (1.87), Georgia (1.83), Minnesota (1.79), and Arizona and New York (tied at 1.74).
