As someone who is hoping to learn more about climate change (and become more immersed in climate tech), this book provided a nice lay of the land. The fundamental driver of climate change is greenhouse gas emissions. Greenhouse gasses trap heat in the atmosphere and too much of them is a problem. They are measured as carbon dioxide equivalents (CO2e) and include carbon dioxide, methane, nitrous oxide, and more. In the pre-industrial era, we had 283ppm CO2e. We are now at 500ppm. To prevent a climate catastrophe, we need to bring this under 430ppm. Doerr breaks this book out into 10 chapters, each with its own Objectives and Key Results. The topline objective of the book is to reach net-zero emissions by 2050, and get halfway there by 2030. The current drivers of greenhouse gas emissions are energy (41%), industry (20%), agriculture (15%), transport (14%) and nature (10%). To save me some time, the OKRs are below. Apologies in advance for the poor image quality. You can read about them in more depth at the Speed and Scale website. I’ve also left some of my own notes below.
