Details

The Green Book is the UK government guidance on appraisal, which is the process of assessing the costs, benefits and risks of different options to achieve government objectives. It is recognised internationally as an example of good practice. In January 2025, the Chancellor announced a review of the Green Book and how it is being used to ensure ministers and other decision makers are confident that they are receiving fair, objective and transparent advice on investments across the different regions of the United Kingdom. The review has not found conclusive evidence that the methodology set out in the Green Book is itself biased towards certain regions. However, HM Treasury has identified six important issues that need to be addressed. This report sets out the review’s findings and the subsequent actions that HM Treasury will take to improve appraisal across the public sector.
