With the green building movement now in its second decade, Giants 300 firms have made sustainability comparable to breathing. They do it automatically.
New this year: charts showing the total number of green accredited staff—in addition to LEED APs and LEED Green Associates, the total includes Certified Energy Auditors and Managers, Certified Sustainable Building Advisors, Green Advantage Certified Professionals, Green Globes Assessors and Professionals, Green Roof Professionals, and High-Performance Building Design Professionals.
Note: An AEC professional who is, for example, both a LEED AP and a CEM would be counted in both categories.
Below, you’ll find rankings of green accredited professionals as a percentage of total employees in the firm. We did this to recognize smaller firms that have a high percentage of green-certified staff. +
