“Chicago has just 29 buildings and projects that bear the equivalent of the Good Housekeeping Seal of Approval from the U.S. Green Building Council, the Washington-based non-profit that sets the standards for what is officially considered green. While that is more than any other American city except Seattle and Portland, Ore., it nonetheless represents a tiny fraction of Chicago’s total of more than 500,000 buildings. More broadly, it is a sign that the fledging green movement has mountains to climb before it achieves broad acceptance.”
