New Book: REGEN360
An Operating System For A Regenerative Earth
Coming October 2026
Available for Preorder:
CIVILIZATION IS RUNNING ON VERSION 1.0.
It counts everything except life.
David Gottfried co-founded the U.S. Green Building Council, founded the World Green Building Council, and helped create LEED. Three decades later, buildings improved. The operating system beneath them never did.
Regen360 is Gottfried's reckoning with why. Version 1.0 rewards extraction, speed, and short-term profit. Life pays the bill. Version 2.0 is RegenOS: fifteen Earth Codes, one operating system, one question. Does this increase Health on Planet Earth (HOPE), or degrade it?
He runs the same diagnostic on himself. A twenty-year marriage he held together with his own silence, until he finally spoke and it broke. His father's paperweight read Do not confuse effort with results. His daughter inherits whatever we leave running.
Net worth fades. Self-worth bends with ego and applause. Soul Worth survives the eulogy.
The new code is written. Do we have the guts to run it?

Book Testimonials
"David Gottfried doesn't moralize; he analyzes. He gives us code — fifteen Earth Code equations, nestled in a framework called HOPE. At this bleak moment in our planet's history, hope is just what we need."
— Denis Hayes, founder of Earth Day; President Emeritus, Bullitt Foundation
"Regen360 is his most honest book yet — part memoir, part systems manifesto, part father's reckoning with what his daughter's generation is inheriting. He's not selling optimism. He's offering an operating system. That distinction matters, and so does this book."
— Chip Conley, New York Times bestselling author and founder of MEA
"Regen360 is what happens when someone who helped build the green building movement steps back and interrogates his own life's work with total honesty. It's essential reading for the journey forward."
— Joel Makower, Chairman and Co-founder, Trellis Group
"David Gottfried has long challenged the building and construction industry to think bigger, and Regen360 does exactly that — showing that the next phase depends on accelerating solutions we already know are possible by aligning mindsets, capital and action at scale."
— Cristina Gamboa, CEO, World Green Building Council
"In Regen360, you will discover a work that is as deeply authentic, inquisitive, and compelling as David himself."
— Jean Rogers, PhD, Founder and former CEO, Sustainability Accounting Standards Board
