Recommendation 18

18

Green Book changes aim to improve place-based interventions by aggregating benefits from multiple projects.

Recommendation
We asked about how changes to the Green Book will ensure that projects are effective place-based interventions. The Treasury outlined that the key objective of the place-based business case is to bring together all the different projects that will make a substantial difference to a particular place, and where these projects are greater than the sum of their parts. It said that this approach would not necessarily apply to mega projects but would be important for a number of individual projects or programmes to bring out the benefits that would perhaps not be seen on an individual basis.35 33 Q 44 34 Q 45 35 Q 37 13 2 NISTA’s new role Ensuring that HM Treasury and NISTA gains assurance about progress with all major projects
