About GBCI

GBCI is the premier organization independently recognizing excellence in green business industry performance and practice globally.

Through rigorous certification and credentialing standards, GBCI drives adoption of green building and business practices.

GBCI is the global certification body for the LEED green building program. LEED was founded more than 20 years ago to provide a road map for developing sustainable buildings. Today, LEED is the most widely used green building program in the world with more than 102,000 registered and certified commercial projects across 178 countries and territories.

LEED is at the heart of everything we do, but we want our community to have the option to go further, get faster and dive deeper into the areas you care about. So over the last several years, GBCI has expanded to administer several other complementary rating systems and credentialing programs that cover nearly every facet of the sustainability industry including LEED, TRUE, PEER, SITES, WELL, EDGE, ICP, and RELi.

With the addition of these programs, GBCI is consistently advancing our strategy to create new markets, build capacity and create value. Together, these programs complement LEED and ensure we are addressing all areas of the sustainability community as we work toward a common goal of ensuring a sustainable, healthy future for all.

By investing in GBCI and in new rating systems, we aren’t undermining the focus on LEED. We are doubling down on how to augment it, how to add layer after layer, how to promote the issues that most affect our communities like waste, equity and resilience – particularly in the face of climate-related risks – and how to protect the human health and wellbeing of all of us.

GBCI provides its customers with trusted, quality third-party certification and award-winning customer service. Dedicated technical experts specializing in architecture, engineering and building management at GBCI ensure building certification meets the highest levels of quality and integrity.

GBCI has a global strategic partnership with Bureau Veritas to deliver onsite certification and verification as well in country support to project teams. GBCI is known around the globe for its commitment to quality and transparency.


GBCI works rigorously to maintain quality control on the project certification through global green building standards set and annually reviewed by our board members. GBCI credentialing programs are developed, delivered and maintained using best practices in test development. Since 2011, GBCI’s LEED credentialing programs have been ANSI-accredited under the ISO/IEC 17024:2012, Conformity assessment – General requirements for bodies operating certification of persons.

The quality and rigor of project certification is maintained through standards viewable in fully documented manuals available to the public. These standards are internationally renowned to follow best practices that allow GBCI to be transparent and open to feedback.

As an independent certifying and credentialing agency, GBCI has managed the certification of more than 3 billion square feet of real estate and the credentialing of nearly 190,000 green building professionals (a number that is almost equivalent to the number of architects in the U.S.).
