Amy Smart and TV handyman Carter Oosterhouse met at an environmental conference, so there was never any question that their September 2011 dream wedding in his Michigan hometown would be eco-friendly. Carter used his woodworking skills to build the bar out of reclaimed wood, the dinner and flowers were locally sourced, and even the seating cards were nature-based. Just how green was it? With a 220-person guest list, the couple were left with only a single bag of garbage at the end of the night.
