Mr. Liam O'Sullivan:

Absolutely. There is an initial cost, but based on information we have from trials and judged over 20 or 25 years, this will be very positive for the country in terms of economic benefits and reduced emissions. Somebody spoke earlier about particulates but they are effectively eliminated in the change from diesel to CNG. There is a contribution with regard to CO2, NOx, SOx, particles etc. There are major benefits and, ultimately, there will be an economic benefit to the country because we will avoid fines and so on that would otherwise come our way.
