The premier organization independently recognizing excellence in green business industry performance and practice globally. Through rigorous certification and professional credentialing programs, GBCI drives the adoption of green building and sustainable business practices globally.
With the emergence of COVID-19, GBCI has adapted our certification review process to provide project teams flexibility, help them update their certification work plans and extend timelines. Our goal is to steady the ship for our customers and focus on the health and safety of all people involved in certification and verification activities.
How we transform the market
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.
While LEED is GBCI’s most well-known program, over the last several years, GBCI has also expanded to administer several other complementary rating systems that cover nearly every facet of the sustainability industry. 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.
Building a global network of leaders
GBCI’s credentials demonstrate proficiency in green building and sustainability, and are a way for professionals to showcase their knowledge, experience and credibility in the green building and sustainability marketplace. Whether you are a student, emerging professional or industry expert, GBCI offers a full suite of 15 credentials and certificate programs that strengthen your resume, help you stand out from the crowd and showcase your knowledge and expertise to the industry and potential employers.
In response to COVID-19, we now offer online testing for all of our programs including the LEED Green Associate, LEED AP with specialty, WELL AP, SITES AP and Urban Greenhouse Gas Inventory Specialist exams.
GBCI credentials consist of competency exams and certificate programs. The GBCI credentialing team consists of program managers, test developers and psychometricians who design, develop and maintain the credentialing exams.
The exams are constructed using rigorous test development best practices to assess whether working professionals have the minimum competencies to perform their jobs. GBCI credentials require ongoing maintenance to encourage credentialed professionals to participate in learning experiences that demonstrate continued competency and up-to-date industry knowledge.
GBCI has received and maintained Personnel Certification accreditation from the American National Standards Institute (ANSI) since 2011. Accreditation ensures that a certification agency meets a recognized standard for the programs and services it employs, and that the certification agency is engaged in continuous review and quality improvement.
A LEED credential denotes proficiency in today’s sustainable design, construction and operations standards. More than 205,000 professionals have earned a LEED credential to help advance their careers. GBCI develops and administers the ANSI-accredited LEED professional credential exams, which include the LEED Green Associate and LEED AP with specialty credentials.
