I apologise to the noble Baroness—I am so sorry, but I am trying to juggle 300 devices. That is a slight exaggeration, if I am honest. We recognise the importance of ensuring that all chemicals in the NHS supply chain are appropriate and properly managed as part of the net-zero strategy. I think the noble Lord, Lord Stevens, even touched upon some of the chemicals that were used and some of the issues he looked at during his time at the NHS when it comes to chemicals. The NHS must also comply fully with the Control of Substances Hazardous to Health Regulations, the CoSHH regulations.
More broadly, although Defra is the lead department for harmful chemicals, the UK Health Security Agency feeds in its expertise in relation to restricting and banning chemicals, and we are grateful to it for that work. The UKHSA is also looking at each of those chemicals, which we hope in future can be replaced by less harmful materials and chemicals. I undertake to write to the noble Baroness in more detail than the short answer I have given her at this stage.
