Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if she will include section 17(5) of the Environment Act 2021 in the Green Book.

Ministers of the Crown have a legal duty to have due regard to the environmental principles policy statement when making policy, in line with section 19 of the Environment Act 2021.

This is made clear on the Green Book webpage and will be reflected in the Green Book when the document is next updated.
