Solutions Library

Each solution reduces greenhouse gases by avoiding emissions and/or by sequestering carbon dioxide already in the atmosphere.

Project Drawdown conducts ongoing review and analysis of practices and technologies that are able to reduce greenhouse gas concentrations in Earth’s atmosphere and also are 1) currently available, 2) growing in scale, 3) financially viable, 4) able to have a net positive impact, and 5) quantifiable under different scenarios. 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. 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. 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.
