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.
