“Securing a spot on this list is a remarkable achievement for everyone involved in the green building movement in these states,” said Rick Fedrizzi, president, CEO, and founding chair, USGBC. “From architects and designers to local chapter advocates, their collective efforts have brought sustainable building design and use to the forefront of the national discussion on the environment, and I applaud their efforts to create a healthier present and future for the people of their states.”
