UNDO

UNDO

Glasgow, UK

Permanent carbon dioxide removal with added co-benefits.

UNDO spreads crushed silicate rock on agricultural land, removing carbon dioxide from the atmosphere while enhancing soil health through a process called enhanced rock weathering. UNDO aims to spread enough rock by 2025 to remove one million tonnes of CO₂, a first step towards gigatonne-scale operations.
