Mr. Gerry Brady:

It is a mixture of rebates. We use the excise rate on petrol as a benchmark. When a comparison is made with diesel, marked gas oil or kerosene, which have a lower excise rate, the amount of revenue forgone can be seen. The quantity of auto diesel may be 3.5 billion litres. When that is multiplied by the difference in the excise tax, a calculation of revenue forgone for auto diesel can be made.
