D.C. leads the region in “green” building space, according to the first analysis of green building trends in the National Capital Region.

Between 2003 and 2009, there were 72 LEED-certified projects in the District. Virginia ranked second in the region with 59 projects, while Maryland had 40 for the same time period.

LEED certification is a program that rates buildings based on how well they meet or incorporate environmentally-friendly practices into their operations.

The “Green Buildings Trend” report, released Wednesday by the Metropolitan Washington Council of Governments, is based on a national report that ranks all 50 states and the District of Columbia in terms of green building practices.
