The duty does not require us to maintain a comprehensive list of policies within scope of the duty. The duty applies to all policies made from 1 November 2023, whether developed by a central department or an arm’s length body, which are: made by Ministers of the Crown; and not covered by the exemptions for the armed forces, defence or national security, taxation, spending or the allocation of resources within government. The environmental principles policy statement provides further information on what is considered policy in scope of the duty. Examples include strategies and frameworks.
