Five years ago Project Drawdown published a collection of “drawdown solutions,” technologies and practices that, if ambitiously implemented together, can achieve drawdown—the point in the future when levels of greenhouse gases in the atmosphere stop climbing and start to steadily decline, thereby stopping catastrophic climate change. A newly released update of this landmark analysis adds 11 new solutions and confirms with even more clarity and conviction that humanity has the solutions needed to reach drawdown quickly, safely, efficiently, and equitably.
