UNDO has been awarded a contract to provide Microsoft with its first carbon removal via enhanced rock weathering (ERW). The award will contribute towards Microsoft’s commitment to becoming carbon negative by 2030 and removing all of its historic CO₂ emissions by 2050.

As part of the agreement with Microsoft, UNDO will spread 25,000 tonnes of mineral-rich basalt rock on agricultural land in the UK, which will permanently remove approximately 5,000 tonnes of CO₂ over the next 20 years. The rock is a by-product supplied by our partner Breedon’s Cragmill Quarry in North East England and spread using existing machinery. As well as funding UNDO’s ERW operations, Microsoft will be funding UNDO’s Measurement, Reporting, and Verification (MRV) enhancement and agronomy trials.
