Health on Planet Earth, with David Gottfried
David Gottfried founded the World Green Building Council, a movement now spanning 85 countries and billions of square feet of certified green buildings. David is a Stanford-trained engineer, four-time author, and keynote speaker. His fourth book, Regen360: An Operating System for a Regenerative Earth, publishes October 2026.
The book goes beyond green building to take on a harder question: what if the operating logic underneath our civilisation is the problem? David proposes an Earth Code — 18 governing codes for a regenerative future — and a framework called HOPE: Health on Planet Earth. When you run the code, you get the Fourth World — the one we forgot to build.
