Everyone wants kids to grow up smart. A child's educational success depends on good teachers, challenging curricula and involved parents. Student achievement also can be affected by the healthfulness of a school's environment. That environment includes the restrooms that consume millions of gallons of water on campuses throughout the nation. Education institutions that embrace environmentally friendly products and technologies for restrooms can cut down on water and energy use, and save valuable resources. At last year's annual meeting of the U.S. Conference of Mayors, the mayors cited studies that identified the benefits of learning in a green school and the urgent need for more healthful and productive places of learning. They noted the benefits of improved indoor air quality, including lower asthma rates, fewer allergies, reduced absenteeism and increased teacher retention rates. The mayors also urged Congress to support K-12 green school demonstration projects and research to better understand the environmental, economic and health benefits of green schools. The consensus was that if schools and universities do not invest in more efficient, energy-saving products and installations, their cost of operations will increase, and student performance will suffer.
