Microsoft and UNDO have announced a new carbon removal agreement to capture 28,900 tonnes of carbon by 2036, supported by innovative debt financing from Canadian climate fund Inlandsis.

On Oct. 21, UNDO, a U.K.-based carbon removal company, and Microsoft announced a new agreement to remove 28,900 tonnes of carbon dioxide (CO2) by 2036. The project, supported by innovative debt financing from the Canadian climate fund Inlandsis, will utilize wollastonite sourced from the Canadian Wollastonite mine near Seeley’s Bay, in a process known as enhanced rock weathering (ERW). By spreading finely crushed silicate rock on farmland, UNDO accelerates a natural chemical reaction that captures CO2 from the atmosphere and stores it in a stable form in soil and groundwater for centuries.
