"The recently announced 2020 Top 10 States for LEED Professionals showcases the growing body of LEED credential and certificate holders across the U.S., with California ranking first in the nation. Using their skills and expertise, LEED professionals support the sustainable transformation of buildings and the growth of a healthier, more equitable economy.

Accompanying the Top 10 States for LEED list for the first time, this new ranking is based on the current active numbers of LEED Green Associates, LEED APs and LEED Green Raters in each state. More than 100,000 LEED professionals live in these states, part of a global network of more than 204,000 professionals.

California's 26,906 green professionals brought the state to its number one ranking. New York follows at number two, with 12,575, and Texas rounds out the top three, with 10,474. Among this year's Top 10, Colorado has the distinction of the highest percentage of the population holding a LEED credential.

Through acquiring and maintaining LEED credentials, the professionals in these states have demonstrated their commitment to the health and sustainability of their communities.
