2026: The New Green Book and Business Cases for Major Transport Projects
Hosted by Transport Planning Society
The new Green Book was published by Treasury at the beginning of February. While it gives much greater clarity on how cost benefit analysis and metrics such as benefit cost ratios should be used to support scheme longlisting and shortlisting, and the assessment of value for money, it still leaves many unanswered questions. In particular, how should place-based business cases inform a scheme-based business case? And what is the role of vision-led strategy made up of a portfolio of interventions when it comes to making the case for a scheme? Come and join the discussion and help shape the future direction of guidance.
