According to July totals provided by the USGBC, there are roughly 7,665 accredited professionals in the U.S.; 1,044 in Canada and about 13 members from other points abroad.

Which states have the highest number of LEED-qualified individuals? Of course, state population is a big driver, but the most recent count is as follows:

California 1,567

Washington 669

New York 527

Texas 505

Massachusetts 469

Colorado 423

Pennsylvania 422

Georgia 404

Illinois 383

Virginia 365

Membership from British Columbia would fall at number six on the “state” list, with 432 LEED-accredited professionals.
