LEED Certification Levels
“Quit thinking about decent land-use as solely an economic problem. Examine each question in terms of what is ethically and esthetically right, as well as what is economically expedient. A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise.”
-Aldo Leopold, Ecologist
LEED offers four certification levels to distinguish how green a building is: Certified, Silver, Gold, and Platinum.
