Our firm held off from signing the AIA Materials Pledge because it was perceived as a feel-good commitment to promise to have good intentions, with no tracking.  I was pleased to learn yesterday that reporting for signatories of the AIA Materials Pledge would "open" today (July 18) and close August 31, and would include mandatory reporting on...
