§ Mr. Ernie Robertsasked the Prime Minister if Her Majesty's Government will introduce legislation to provide for the compulsory fitting of vehicle exhaust gas filters to eliminate lead from vehicle emission.
§ The Prime MinisterThe Government considered the case for lead filters before deciding that it is preferable and more effective to reduce the lead content of petrol from 0.4 to 0.15 grammes per litre. This will reduce the lead emissions from vehicles by more than 60 per cent. If a further reduction were required, filters would be considered as an alternative to lead-free petrol.
