To solve the seemingly-insurmountable climate crisis, we have to take collective action, drive societal change and accelerate the net zero economy using a plan of speed and scale. And we have to start now. In Speed and Scale, award-winning author and investor John Doerr convenes the world's foremost change-makers to show us how we can, if we fully commit to a high-stakes action plan, cut carbon emissions in half by 2030 and reach Net Zero by 2050. He shares practical efforts that individuals, businesses and politicians must take, applying Objectives and Key Results (OKRs)—the simple but powerful tools that scale small ideas into global movements—to our climate goals, setting out the standards that we need to reach as leaders. Featuring exclusive interviews with the world's most influential climate and business thinkers, including Bill Gates, Christina Figueres, Elon Musk, Marry Barra, Jeff Bezos and Al Gore, this is the only global and definitive action plan for how we might save our planet.
