In early March, USGBC released a white paper titled “The Legal Risk in Building Green: New Wine in Old Bottles?” The eight-page paper, which was presented as a panel discussion between four attorneys, concluded that “[p]erhaps surprisingly, in light of the increased attention in seminars and workshops . . . much of the discussion among the attorneys [in the paper] suggests that many of the legal theories advanced in those venues to suggest novel liability associated with building green are, instead, simply new wine in old bottles.” While the paper does not appear on the USGBC’s web site, it was circulated by individual chapters; I accessed a copy through our New York chapter’s weekly email blast and have included a link to download the paper from the USGBC-NY homepage below. I applaud USGBC for taking a critical step towards acknowledging the liability implications of green real estate development and construction, but do think it is important for attorneys practicing in this space to digest the paper’s conclusions. Although the paper does identify and discuss many important legal issues, I think that it ultimately falls short of elevating the analysis of such issues to the level necessary for legislators and stakeholders to make completely informed policy- and project-related decisions. Specifically, by suggesting that “[c]onjecture, anecdote, and even rumor swirl around recent presentations, workshops and discussions circling the question of what legal claims may be based on the design, development, and construction of sustainable buildings,” the paper seems to be an effort to sweep many of the thornier legal issues that may indeed ferment into “new wine” under the rug.
