than ever, we need a clear course of action. What if the goal-setting techniques that powered the rise of today's most innovative organizations were brought to bear on humanity's greatest challenge? Fueled by a powerful tool called Objectives and Key Results (OKRs), SPEED & SCALE offers an unprecedented global plan for cutting greenhouse gas emissions and preserving a habitable planet. Used by Google, Bono's ONE foundation, and startups the world over, OKRs have scaled ideas into achievements that changed the world. With clear-eyed realism and science- backed precision, Doerr identifies the OKRs we need to reduce emissions across every sector of the economy and to arrive by 2050 at net zero-the point where we are no longer adding to the heat-trapping carbon in the atmosphere. By turns pragmatic and inspiring, SPEED & SCALE intersperses Doerr's wide- ranging analysis with firsthand accounts from Jeff Bezos, Christiana Figueres, Al Gore, Mary Barra, Bill Gates, and other intrepid policy leaders, entrepreneurs, scientists, and activists. A launchpad for those who want to act now, this book is geared to ambitious leaders of every kind. With a definitive plan, science, and a rising climate movement on our side, we can still reach net zero before it is too late. But as Doerr reminds us, there is no more time to waste.
