We have many potential options for capturing and storing CO₂. These can be nature-based (tree planting, regenerative agriculture) or engineered, such as DAC. Some of these options cannot guarantee that the CO₂ will remain sequestered indefinitely. Carbon removal that lasts 50 years has little to no impact on preventing global warming. Trees planted for afforestation projects can be decimated by wildfires, releasing and reversing sequestered carbon.
Carbon removal with durations of 1,000+ years is increasingly required by international standards. Our mineralizing process effectively stores carbon durably and irreversibly for geological timescales of 10,000+ years.
