Supplementary memorandum submitted by TRL (AQ 33)
In reference to some of the costs for the technologies discussed in relation to Q39:
1. It is envisaged that the two technologies concerned Selective Catalytic Reduction (SCR) and Diesel Particulate Filters (DPF), will essentially be required on all new vehicles to meet the new Euro VI standard. This will come into effect for Heavy Duty Engines in 2013 and for Light passenger and commercial vehicles in 2014. Hence, for these vehicles it is likely the costs will be incorporated within the manufacturer's price of the vehicle/engine.
2. These specific emission-control technologies can be retrofitted. The costs will vary depending on the type of vehicle, the baseline Euro standard and the target Euro standard. For heavy duty vehicles, figures ranging from £5,000–10,000 for SCR (Energy Saving Trust, 2003) and around £5,000 for DPFs (based on Case studies on the Transport for London website) seem typical. In addition there are running and maintenance costs. Furthermore, DPFs and SCR can be fitted in combination which is likely to reduce the costs. Costs for light-duty vehicles are lower.
