Watershed customers Aledade, Canva, SKIMS, Skyscanner, Wise, and Zendesk are participating in $58.3M in carbon removal offtake agreements from Vaulted Deep, a waste biomass supplier, via Watershed’s partnership with Frontier.
Vaulted will remove 152,480 tonnes of CO₂ by 2027 on behalf of Frontier buyers, with 18,321 tonnes expected to be delivered in 2024. Vaulted’s approach offers 10,000+ year permanence, near-term scalability, and local co-benefits.
Vaulted removes emitted carbon dioxide from the atmosphere by injecting carbon-rich organic waste deep underground for permanent storage. Their approach starts with plants that naturally absorb CO₂ from the atmosphere via photosynthesis. Much of that plant life ends up as carbon-rich waste in the form of biosolids, manure, food, or agricultural waste that is incinerated, landfilled, or spread on land. As that waste burns or decomposes, the once-captured CO₂ is released back into the atmosphere. Vaulted prevents that from happening by turning that waste into a carbon-rich slurry and then injecting it into deep disposal wells for permanent geologic storage.
In addition to removing carbon, Vaulted offers a safe way to dispose of waste like biosolids, manure, food and agricultural waste, and papermill sludge. The typical disposal methods for this waste can create a number of problems for nearby communities, including soil, water, and air pollution; Vaulted’s solution has the potential to reduce environmental and human health harms in surrounding communities.

In addition to Watershed’s customers, Frontier facilitated these purchases on behalf of Founding Members Stripe, Alphabet, Shopify, Meta, and McKinsey Sustainability, as well as Autodesk, H&M Group, JPMorgan Chase, and Workday.
