Which States LEED the Way in Green Buildings?

Which states have the most LEED-certified building square footage per capita? The U.S. Green Building Council has crunched the numbers, and the results are in, with the District of Columbia leading the country in LEED-certified commercial and institutional green buildings (per capita, based on 2010 Census data). In 2011, our nation’s capital boasted more than 31 square feet of LEED-certified space per person, including the Treasury Building (how green can you get?), which happens to be the oldest LEED-certified project in the world.
