DrawdownExplorer

Your ultimate guide to stopping climate change

We know what we need to do: stop climate change as quickly as possible. Now, with the Drawdown Explorer, we know how to do it.

Building upon thousands of hours of analysis by scientific experts from around the world, the Drawdown Explorer provides detailed information on 100-plus technologies and practices proven or proposed to effectively reduce greenhouse gas concentrations in the atmosphere.

The Drawdown Explorer analyzes solutions in four categories:

Highly Recommended: solutions that meet Project Drawdown’s criteria for global climate solutions
Worthwhile: solutions that may help mitigate climate change or have additional benefits but do not meet the scale to be considered a global climate solution
Keep Watching: solutions that have potential but given current technology, cost, or adoption, are not yet ready to be deployed
Not Recommended: solutions we do not expect to be global climate solutions either due to lack of evidence for their effectiveness, high costs, or high risk.

Browse the full complement of Drawdown Explorer solutions below, or filter by criteria of your choice using dropdowns or the table format. Then click through to individual solutions to get a close-up view of current and potential impact – including, for recommended solutions, the optimal timing, cost, additional benefits, interactive maps showing where action can have the greatest impact, and specific advice for how you, whatever your role, can best put the solution to work.

Primer FAQs Methodology Acknowledgments

From Science to Solutions

The climate crisis is urgent, so it’s critical that the solutions are fast-acting and effective.

Drawdown Explorer identifies and characterizes the most effective climate solutions that can address climate change on a meaningful scale today. It also provides valuable insights into proposed solutions that are not viable, not impactful enough, or not yet ready for prime time.

See A Primer on Science-Based Climate Solutions to learn more about the science behind our next-generation guide to meaningful climate action.
