Former President Barack Obama will deliver the keynote speech at the 2019 Greenbuild International Conference and Expo this year in Atlanta, Georgia. 

The conference is organized by the United States Green Building Council (USGBC), and bills itself as "the only event genuinely dedicated to sustainability in the built environment, from the sessions we present to the products on the show floor to the way the event is produced," according to its website.

Mahesh Ramanujam, president & CEO of USGBC, said via press release, “President Obama is a global leader and a long-time friend of the green building community. While in office, his administration negotiated the landmark Paris Climate Accords, expanded the impact of our field and helped open the door for energy efficiency investments in both the public and private sectors," adding, "I know that when he joins us on the keynote stage in November, he will impart his ideas, passion and vision to our growing global green building family.”

The conference and expo are set to take place between November 19 and 22, 2019; Climate activist Jamie Margolin is also set to give a keynote presentation at the conference.
