The New Approach to Transport Appraisal (NATA) was introduced in 1998 as part of the government’s integrated transport policy. In May 2007, The Department for Transport (DfT) announced that it was to ’refresh’ NATA and has published a detailed consultation document.This report contributes to the refresh by asking two fundamental questions. The first is whether NATA delivers an appraisal process that accurately represents the true costs and benefits of transport schemes and fully reflects the government’s objectives in general and, in particular, its climate change targets. The second issue is whether NATA’s basic principles have been followed in practice.
