Colorado and Illinois have pushed out New Mexico and Nevada in the U.S. Green Building Council's annual ranking of states by certified LEED space per capita, while Washington, D.C. continues to leave all states behind in its wake.The capital city had 18.9 million square feet earn LEED certification in 2011, or 31.5 square feet per person – miles ahead of Colorado at 2.74 and Illinois at 2.69.
Of course, the District has a few unfair advantages over its competitors. Being a city rather than a state, it has a comparatively high density of buildings, and a high proportion of those buildings belong to the federal government, which has pushed its agencies to adopt green building practices. D.C. also has only about 600,000 residents.
Washington, D.C. also came first in last year’s rankings, when it was followed by Nevada, New Mexico and New Hampshire. But those states are nowhere to be found in this year’s top 11.
The top states this year were:
Sq. ft. of space earning LEED certification in 2011 | Per capita | |
| District of Columbia | 18,954,022 | 31.50 |
| Colorado | 13,803,113 | 2.74 |
| Illinois | 34,567,585 | 2.69 |
