About us

At Arca, we pull carbon dioxide from the air and store it permanently as rock. To do this at scale, we partner with the minerals industry to implement our technology at mine sites, using their rock waste as our feedstock. These are the same mines that are producing the minerals necessary for the transition to a clean energy future. Arca’s founders are leaders in the field of carbon capture in mine tailings with more than 20 years of experience in innovation and research.

We believe that by working with nature, not against it, we can achieve carbon dioxide removal on the scale needed to secure thriving and abundant life on Earth for generations to come. If that resonates, we want to hear from you. We’re building a team of sharp, mission-driven, and collaborative individuals who take pride in using their skills to contribute to a sustainable future.
