The U.S. Green Building Council reported that Illinois has 3.09 square feet of LEED-certified commercial and institutional green buildings per capita — ranking it eighth in the nation.

That’s based on 2010 census information. LEED stands for Leadership in Energy and Environmental Design.

Washington D.C. led the council’s list with 25.15 square feet per person, followed by Nevada with nearly 11 square feet per person. Other states that made the top ten were New Mexico, New Hampshire and Oregon.
