The new Green Book ensures that investment decisions are no longer based solely on single metrics, such as benefit-cost ratios, and that decisions instead take into account the full range of impacts on people and places.

This new approach will shape important decisions, such as on Northern Powerhouse Rail, and ensure that government investment brings about higher living standards in every part of the country. This includes urban, rural and coastal communities.
