Image Paul Wermer (NCC Representative)
Trained as a chemist, Paul’s focus on sustainable practices began while he managed materials development programs in the semiconductor industry. Work on environmentally related projects highlighted how significant both regulatory and market forces are in influencing business actions, and the power of advocacy in shaping both those forces. Following his interests, he joined Global Footprint Network as a senior scientist, where he applied the Ecological Footprint as a sustainability metric in a number of projects – and was astonished at the resource impacts of building and remodeling practices. This evolved into an interest in land use and green building practices. Paul has been active in USGBC-NCC’s State Advocacy activities since 2008.
