To ask the Secretary of State for Energy Security and Net Zero, if she will update her Department’s greenhouse gas removals business model to include (a) enhanced rock weathering and (b) other technologies that do not use carbon capture and storage.

The Government recognises the potential role of greenhouse gas removal (GGR) technologies that do not require carbon capture and storage (CCS) in meeting net zero, including enhanced rock weathering, though specific technical and regulatory barriers must be addressed before any decisions can be made on their eligibility for the GGR business model. As set out in the government response to the GGR business model consultation, published in June 2023, this includes the need for further evidence on permanence, reversibility, and environmental impacts associated with these methods.
The Government is working closely with academics, industry, and the UK Research and Innovation (UKRI) GGR Demonstrator projects to investigate the feasibility of scaling non-CCS GGR technologies in future.
