A list of every carbon dioxide removal (CDR) company in the world

Or at least all the ones I could find as of October 2025

Almost two years ago, I published a list of every direct air capture (DAC) company in the world to support job seekers, analysts, and various other groups in understanding the actual DAC landscape on the ground. I received a ton of positive feedback regarding the impact of the list, including from some unexpected groups like industrial equipment vendors. Ultimately, the project informed the development of an official DAC definition and company analysis report I put together while working at the Department of Energy, which drove additional attention to and insight into the space.

To expand on this effort, I painstakingly combed through dozens of other CDR company lists and leveraged my experience in the industry to develop what I believe is the most comprehensive and up-to-date CDR company list in the world. To focus the list, it only includes active, incorporated companies working on durable CDR and excludes artisanal biochar. Please see below to explore.

I also recorded an episode on the Reversing Climate Change podcast where I had the great pleasure of discussing the origin of the list and other takeaways with my friend Ross Kenyon. You can listen to the episode here.

Due to the sheer number of CDR companies (708 at the time of publication), an English-language bias, and how volatile CDR is right now, I am 100% confident that the list is not 100% correct but am 90% confident that it is 90% correct. You can help improve this confidence level by submitting new companies and update requests using this form.

Putting this resource together was a fascinating exercise. Some quantitative insights can be seen on the “Analysis” tab, but it is fun to pry a level deeper and ask why some of the results are what they are.

For example, industrial biochar companies make up over 40% of the total number of companies, which is likely a consequence of biochar having established use cases and production methods prior to the uptick in interest in durable CDR. Biochar, BECCS, and DAC alone make up around 80% of the total companies, which likely reflects their relative technological maturity and heightened interest in technologies offering “closed-system” storage. Around exactly one third of the companies are headquartered in the U.S., with Germany sitting in second place at under 10% and the UK not far behind. The changing political winds in the U.S. paired with the large fraction of CDR companies located here could help explain the disproportionately sour mood in the industry as of late.

I could go on, but I challenge you to dive into the list and come to your own conclusions about the state of play and where the next big opportunity lies. If you’re a job seeker, you can start working on cover letters to apply to all the companies working on your favorite technology!
