Ms Verona Murphy:

They are virtually emissionless. There is an AdBlue aspect whereby it is cleaned before it ever comes out of the exhaust but it is costing us more money. It is 35 cent per litre on top of fuel. That is our contribution; that is what we do. It has also increased the cost of trucks by about €20,000 meaning it is very difficult for someone to purchase to that standard in the current environment. The incentive that is required here is to do like the European model, which is to have an essential-user rebate that works. In Belgium it is 22 cent a litre. In Ireland with the same excise regime it is less than 1 cent. Does that sound right? It is not right. It is why Belgium is running predominantly on a Euro 6 standard fleet.
