§ Ms Lawrence
To ask the Chancellor of the Exchequer what estimate he has made of the revenues which will be obtained by the Treasury under the new definition of ultra-low sulphur diesel in the Finance (No. 2) Bill; and how this compares with the revenues that would be received if no changes were made. 
§ Dawn Primarolo
The decision to change the definition of ultra-low sulphur diesel was made solely for environmental reasons. No separate estimate was made of the revenue effect. It was assumed that the effect on ULSD clearances of the new definition would be broadly offset by the increased demand for ULSD created by simultaneously widening the duty differential with conventional diesel from 1 to 2 per litre.
