Barclays has entered its first major carbon dioxide removal (CDR) agreement, partnering with British climate technology firm UNDO to deploy enhanced rock weathering (ERW) in Canada. The deal covers the removal of 6,538 tonnes of CO₂, marking the largest ERW contract to date led by a UK-based supplier.
Enhanced rock weathering is a nature-based solution that accelerates the natural process of carbon sequestration by spreading crushed basalt rock across agricultural land. As the rock interacts with rainwater and soil, it captures atmospheric CO₂ and stores it in stable mineral forms.
The agreement reflects Barclays’ growing commitment to climate innovation and carbon removal as part of its broader sustainability strategy. UNDO, a leading developer in the ERW space, will implement the project across Canadian farmland, contributing to both carbon drawdown and soil health.
This milestone signals increasing momentum in the voluntary carbon market and highlights the role of financial institutions in scaling durable climate solutions. Barclays joins a growing list of global banks investing in emerging carbon removal technologies to meet net-zero targets and support climate resilience.
