Mr. Liam O'Sullivan:

Absolutely. I agree completely and, to be fair, it is one comment we made. We are seeking incentives for operators to change. If we get a volume of buses, I hope the differential will reduce in time and quickly. As we currently stand, there is a very significant positive upside for the transport provider, which is the difference between the cost of natural gas and its excise treatment versus diesel. It is 79 cent per litre versus €1.19 per litre. There is a positive incentive anyway but the Deputy is right. There should be additional incentives. Similar to electric vehicles, there is an extra cost to buying the vehicle and if there is an incentive for electric vehicles, there should be an incentive for going to CNG.
