§ Dr. David Clarkasked the Secretary of State for the Environment what is his estimate of the percentage reduction (a) NOx (nitrogen oxides), (b) hydrocarbons and (c) atmospheric ozone likely to be achieved by the introduction of vehicle emission control in the United Kingdom by the years 1995, 2005 and 2010, respectively.
§ Mr. Patrick JenkinGaseous emissions from vehicles have been controlled in the United Kingdom since the early 1970s, and the progressive tightening of standards since then will continue to have an effect well into the 1990s. But because the European Community has still to reach final agreement on the limit values to be included in a new directive on vehicle emissions coming into effect in the late 1980s and early 1990s, it is not possible to predict what further emission controls might come into force in the United Kingdom, or to estimate what the overall effects on individual pollutants might be.
