HC Deb 31 January 1983 vol 36 c41W
32. Mr. Parry

asked the Secretary of State for Transport what further progress has been made towards the reduction of lead in petrol.

Mrs. Chalker

Substantial investment by the petroleum industry is under way to implement the Government's decision to reduce the maximum lead content of petrol from 0.40 grams/litre down to 0.15 grams/litre—a 62 per cent. reduction—by the end of 1985. As a result of this, total lead emissions from vehicles which averaged 7,500 tonnes per year during the 1970s will fall to an estimated 2,300 tonnes per year from 1986.
