Other players in the market use direct air capture technologies. Why doesn’t UNDO?

Enhanced rock weathering is presented as a more favorable option compared to direct air capture (DAC) for long-term carbon dioxide removal. ERW promises over 100,000 years of carbon storage, while DAC's storage permanence can vary, with about half of its captured CO₂ injected underground for long-term storage and the rest used in products with shorter-term carbon sequestration potential. 

DAC relies on specialised, often new technology to pull CO₂ from the air, which can be energy-intensive and costly. In contrast, ERW leverages existing agricultural infrastructure for spreading silicate rocks, making it energy-efficient and cost-effective. Moreover, ERW provides additional environmental and socio-economic benefits, such as improved soil health, enhanced crop productivity, and job creation in rural areas, thereby supporting multiple UN Sustainable Development Goals.
