Microsoft Inks Major Carbon Removal Agreement with Biomass Waste Management Firm, Vaulted Deep
Microsoft has entered into a significant 12-year partnership with Vaulted Deep, a waste management startup, to remove up to 4.9 million tonnes of carbon dioxide from the atmosphere by 2038. This marks one of the largest carbon removal agreements to date and underscores a shift towards leveraging existing industrial infrastructure and waste streams for scalable, durable carbon removals.
Vaulted Deep's approach to carbon removal is differentiated and scalable, with low technology risk. The company removes carbon by collecting organic wastes such as biosolids, manure, paper sludge, food waste, and agricultural residues that cannot be reused or safely applied to land. These wastes are blended into a slurry and permanently injected into deep underground porous rock formations via deep well injection. The formations are sealed by impermeable rock layers thousands of feet underground, ensuring long-term carbon storage.
This methodology not only permanently removes carbon from the atmosphere but also reduces methane emissions and helps prevent local environmental contamination from trace pollutants such as PFAS. Vaulted Deep has already removed nearly 18,000 tonnes of CO₂ and diverted over 69,000 tonnes of organic waste. The company’s carbon removal methodology is certified by the Isometric carbon registry, underscoring the durability and reliability of its process.
Microsoft's investment in Vaulted Deep aligns with its updated "Criteria for High-Quality Carbon Dioxide Removal," which emphasize direct measurement and science-based standards for carbon removal technologies. The deal supports Microsoft’s broader climate strategy aimed at scaling high-quality carbon dioxide removal solutions.
The deal with Vaulted Deep is the latest in a series of large-scale carbon credit deals by Microsoft. By far the largest corporate buyer of carbon removal credits globally, Microsoft has announced several multi-million tonne agreements recently. The financial terms of the agreement have not been publicly disclosed.
Vaulted Deep collaborates with municipalities, industrial operators, and agricultural producers to manage their organic waste. The company is actively seeking new waste partners across various industries to manage their hard-to-manage organic waste. The new agreement will enable Vaulted Deep to expand its operations to new sites across the U.S.
The storage offered by Vaulted Deep provides a permanence of over 10,000 years. Julia Reichelstein, co-founder and CEO of Vaulted Deep, made a statement regarding the new deal with Microsoft, saying, "Our work delivers immediate climate benefits while stimulating local economies and addressing long-standing environmental challenges."
With this deal, Microsoft's carbon removal purchases now total over 30 million tonnes. The company faces growing carbon emissions tied to expanding data center operations, challenging its goal to be carbon negative by 2030. Partnering with Vaulted Deep is a strategic move to offset these emissions through verified, large-scale carbon removal.
The deal with Vaulted Deep is a testament to the growing recognition of the potential of existing industrial infrastructure and waste streams for delivering scalable, durable carbon removals. It reflects a broader shift in how carbon removal is being deployed, no longer limited to emerging technologies but increasingly delivered through large-scale existing infrastructure with novel applications.
- The science-driven approach of Vaulted Deep's carbon removal method, certified by the Isometric carbon registry, aligns with Microsoft's updated Criteria for High-Quality Carbon Dioxide Removal, which prioritize direct measurement and science-based standards.
- The partnership between Microsoft and Vaulted Deep, a waste management startup, is a significant step in environmental-science, as it leverages existing industrial infrastructure and waste streams for scalable, durable carbon removals, potentially influencing the business and technology sectors.
- With the latest investment in Vaulted Deep, Microsoft is expanding its carbon removal efforts, aiming to offset growing carbon emissions tied to expanding data center operations, and moving towards its goal of becoming carbon negative by 2030, also supporting its broader climate strategy focused on scaling high-quality carbon dioxide removal solutions in finance.
