Written question asked by Lord Bradshaw (Liberal Democrat), in the House of Lords. It was answered by Earl Attlee (Conservative) on Thursday, 3 March 2011.

Transport: Appraisals

Question: To ask Her Majesty’s Government, further to the Written Statement by Earl Attlee on 4 February (WS 7–10), whether the projects detailed have been assessed using the New Approach to Transport Appraisal (NATA); and, if so, whether NATA has been modified, particularly with regard to the aggregation and valuation of small time-savings.

Answer: Decisions on the projects detailed were supported by information on scheme impacts assessed using the NATA framework. Estimates of the benefit-cost ratio (BCR) used in this assessment were adjusted to account for the impact of wider impacts, reliability, landscape and higher CO2 values consistent with Department of Energy and Climate Change’s latest advice. Benefit-cost ratios were also adjusted in line with draft departmental guidance on the treatment of indirect tax revenues, specifically the impact on fuel duty revenue to the Treasury. No modification was made in regard to the aggregation and valuation of small time-savings.
