§ Mr. David Price
asked the Secretary of State for the Environment what research he is sponsoring into the health hazards of concentrations of carbon monoxide, emanating from vehicle fumes in areas of dense traffic; and when he expects to be able to make a progress report.
§ Mr. Peyton
Extensive studies, carried out by the Medical Research Council, have shown no danger to health from the levels of carbon monoxide found in heavily trafficked areas. I have just published proposals that all petrol engined vehicles manufactured after 1st April, 1973, should comply with the European standards on vehicle emissions. This would reduce emissions of carbon monoxide by up to 30 per cent.
