Thirty-five of the 47 World Green Building Council (WGBC) member councils responding to our survey predicted that there will be at least a 100 percent increase in the number of green-certified buildings (under any rating system) within their countries over the next five years. Also, 37 responding councils forecast that there will be at least a doubling in the size of their memberships during the same period.
Councils participating in the survey, combined, represent more than half of WGBC's membership and serve countries whose populations total an estimated 3.14 billion people.
