For some twenty years this Journal has reported advances in the application of platinum metals catalyst technology for the control of automobile exhaust gases. The first work was directed at reducing atmospheric pollution in Los Angeles, where climatic and topographic conditions, together with a high concentration of automobiles combined to create a clearly perceived problem. Since that time the use of pollution control catalysts for vehicle emission abatement has grown substantially. In Europe, popular concern about the effects of pollution is now being translated into legislation to protect the environment, so it is timely to re-examine the existing evidence of the atmospheric changes caused by motor vehicles, and from that to predict what may happen on a global scale in the future. It is suggested by the author, who was formerly Deputy Assistant Administrator for Mobile Source Air Pollution Control at the U.S. Environmental Protection Agency, that the latest catalyst technology must be applied worldwide, without delay, to prevent further major damage to the environment.
