Drawdown Climate Solutions Library

Our scientific analysis shows that the world can reach drawdown—the point in time when levels of greenhouse gases in the atmosphere stop climbing and start to steadily decline—by mid-century if we make the best use of all existing climate solutions. Each solution presented here reduces greenhouse gases by avoiding emissions and/or by sequestering carbon dioxide already in the atmosphere.

Project Drawdown reviews and analyzes practices and technologies that can reduce greenhouse gas concentrations in Earth’s atmosphere and also are

  • currently available
  • growing in scale
  • financially viable
  • able to have a net positive impact
  • quantifiable under different scenarios.

More solutions are needed and emerging, but there is no reason—or time—to wait. Now is better than new, and society is well equipped for transformation today.

Below you will find links to individual solutions, filterable by sector and area of action. The Table of Solutions link presents all solutions in a table sortable by impact and sector. Each solution includes a “What You Can Do” section with specific suggestions on how you might advance it within your own sphere of influence.

Many Drawdown Solutions can improve human health and equity and provide other benefits in addition to mitigating climate change. Look for the “Co-benefits” sidebar to learn more about the additional benefits of specific solutions.

Our Methods page explains how we arrived at our conclusions for each solution, and a Glossary defines terms used in the solutions summaries. If you would like to see the original, unedited research reports, please contact us.

In addition to providing solution summaries, we are in the process of moving our research models—which help us quantify the potential size and economics of different climate solutions—into the public domain. This process is still in the early stages, and many pieces of software are still under development.  Interested individuals can check out the ongoing work on Github, where Python and Excel versions of the models are being worked on, along with user interfaces, data management tools, and other software tools.
