Leadership in Energy and Environmental Design. LEED is an internationally recognized green building certification system through the U.S. Green Building Council, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

LEED Professional Credentials and Exams are administered by the Green Building Certification Institute. The credentials, such as LEED Green Associate, demonstrate current knowledge of green building technologies, best practices, and the rapidly evolving LEED Rating Systems.
