The built environment has a profound impact on our natural environment,
economy, health, and productivity.
In the United States alone, buildings
• 72% of electricity
• 39% of energy use,
38% of all carbon dioxide (CO2)
• 40% of raw materials use,
30% of waste output (136 million tons annually), and
14% of potable water consumption.
More statistics on the built
environment in the U.S. and the growing size of USGBC membership and LEED are
available in our Green Building by the Numbers document.
