§ Ms. HarmanTo ask the Secretary of State for Transport what are the latest figures for(a) how many and (b) what proportion of (i) new cars use unleaded fuel and (ii) car owners have converted their cars to unleaded fuel, and what proportion this is of cars that can be converted, (iii) new cars have a catalytic converter and (iv) car owners have a catalytic converter fitted.
§ Mr. Kenneth CarlisleAll new petrol-engined cars manufactured since 1 October 1990 have had to be capable of running on unleaded petrol, deliveries of which in November 1992 amounted to 49.2 per cent. of the total figure of 1,925,987 tonnes for deliveries of motor spirit. The number and proportion of older cars adapted to use unleaded is unknown. Since 31 December 1992 virtually all 693W new petrol-engined cars have been fitted with catalysts; and of the total car fleet of some 22.9 million vehicles, the proportion fitted with these devices is currently about 5 per cent.
