At the AIA National Convention in Atlanta, GA, Architecture 2030 Founder and CEO Ed Mazria was officially presented with the Kemper Award.

In his acceptance speech to a packed audience of more than 7,000 architects, Mazria told his colleagues, “Because of your critical role in all this [addressing climate change], because you have a moral imagination and see a purpose in what you’re doing, you have given the world the courage to take bold actions to address the defining issue of our time.”
