“You need some measure of what you mean by sustainability,” said Paul Zofnass, founder of the Zofnass Program for Sustainable Infrastructure at Harvard University. “You can say that sustainable infrastructure is important and everyone nods, ‘Yep, right, sustainable infrastructure is important,’ but what do you mean by sustainability? How do you define it? How do you measure it?”
