In a sense, the interviewer really missed the boat on this last question - anybody building in Manhattan and Brooklyn in inherently building green - the average New Yorker produces a carbon footprint less than 1/3 that of the average American - and I suspect even much lower in Union Square and Williamsburg, where toll is builidng, as those neighborhoods have car ownership well below 10%. Simply having everybody living at the densities in these neighborhoods with the amazing transit available would cure our entire greenhouse gas problem overnight, even if not built close to LEEd standaqrds. Nonetheless, it's a shame that the leader of Toll Brother is such such a smug douche.
