To revise the criteria by which a school may be designated as a “green school” and establish new levels of “green-ness,” including “emerald” and “evergreen.” The new criteria specify in more detail various types of recycling, and add doing energy audits of the homes of students, engaging in letter writing or lobbying campaigns on environmental issues, offering classes in energy or environmental issues, creating a student environmental organization and “eco reading” program, and much more. Some criteria of the current “green school” statute are not included, such as hosting a Sierra Club spokesperson, students dusting coils on cafeteria refrigerators and checking bus tire pressure, etc.
