Project Drawdown conducts an ongoing review and analysis of climate solutions—the practices and technologies that can stem and begin to reduce the excess of greenhouse gases in our atmosphere. Our work shows the world can reach Drawdown by mid-century, if we make the best use of all existing climate solutions. Certainly, more solutions are needed and emerging, but there is no reason—or time—to wait on innovation. Now is better than new, and society is well equipped for transformation today.
