asked the Secretary of State for Transport what is the latest position in regard to motor car exhaust regulations in Great Britain; when new measures will be introduced; and if he will make a statement comparing the position in the United Kingdom with the United States of America and West Germany.
The Motor Vehicles (Construction and Use) Regulations 1973 incorporate standards for controlling the emission of carbon monoxide and hydrocarbons which apply throughout the European Community. Agreement has also been reached in the Community on standard for nitrogen oxide, and my right hon. Friend hopes to introduce them into United Kingdom law early next year. Longer-term standards for all these pollutants are being considered by the United Nations Economic Commission for Europe. The test methods employed by the United States authorities differ from those in Europe, and direct comparison of standards is not practicable; but the United States requirements are generally more stringent.
