The programme for Government includes a commitment to reduce carbon emissions, particularly in respect of diesel. Will the Ministers for Transport, Tourism and Sport and Finance carry out an urgent review of variations in diesel prices at the pumps, which, despite the same company supplying the fuel, can be as much as €10 per fill? There is also a concern, which is not related to diesel laundering, that the integrity of the fuel process may be compromised in terms of the supply of fuel to customers. I ask that the Minister for Finance and Revenue Commissioners examine this matter.

I am not sure whether the Deputy is referring to the quality of diesel or interference with diesel, which is a serious issue that has been under investigation for many years. I will have the Minister reflect on the Deputy's comments. Motorists and consumers have at their disposal instantaneous communications about where cheaper prices apply at filling stations. I will have the Minister respond to the Deputy on the question he asked.
