Costa Rica, Sweden, Australia and Canada are among the countries with active, high-profile certification programs. In the United States, California, Georgia, Pennsylvania, Florida, Michigan, Maine and Vermont all certify green hotels at the state level. The Green Seal and Energy Star programs administered by the U.S. Environmental Protection Agency allow U.S. hotels to self-certify their eco-practices.
