Carboniferous offers large-scale carbon dioxide removal (CDR) using Marine Anoxic Carbon Storage (MACS). This process preserves unused agricultural plant matter in deep-sea, oxygen-free brine pools to sequester carbon permanently. The method leverages natural photosynthesis to draw down atmospheric CO2 for over a millennium.

Problem
The concentration of atmospheric carbon dioxide is increasing, driving climate change. Effective and scalable methods for carbon dioxide removal (CDR) are needed to mitigate these effects and achieve long-term climate goals.
Solution
Carboniferous employs Anoxic Biological Carbon Sequestration (ABC'S), a method that leverages the natural ability of plants to capture carbon dioxide and then stores the resulting biomass in deep hypersaline anoxic basins. These basins provide a stable, oxygen-free environment that prevents the biomass from decomposing and releasing carbon back into the atmosphere, ensuring long-term carbon permanence. The company focuses on validating the safety and efficacy of this process through rigorous laboratory and real-world experiments, with the goal of scaling to megaton-scale carbon dioxide removal. By combining carbon fixation with durable preservation, Carboniferous offers a nature-based solution for large-scale carbon sequestration.
Target Audience
Carboniferous targets organizations and governments seeking large-scale, durable carbon dioxide removal solutions to meet climate goals and offset emissions.
