Often in green communities, homeowner understanding is left out of the project. We evaluated the impact of a new environmental education program installed in a green community, Town of Harmony, Florida. Consisting of educational kiosks, website, and brochure, we evaluated whether Harmony residents' environmental knowledge, attitudes, and behaviors improved when compared to residents of a conventional community. After two years of exposure to the program, Harmony homeowners did show some improvement in environmental knowledge, attitudes, and behaviors and the control community did not. Such on-site educational programs can help homeowners understand ways to manage their homes, yards, and neighborhoods in a more sustainable manner. (Contains 2 tables and 1 figure.)
