William McDonough’s message for TEDxRio
Our founder, William McDonough, was invited to speak at TEDxRio, which preceded the Rio+20 Summit. Because he couldn’t be there in person, he sent a video message instead.
He delivered a brief statement, referencing The Hannover Principles, which he presented at the Rio Earth Summit in 1992. Here’s the link, via YouTube, to that video message.
