It is widely acknowledged that automobiles are becoming dominant contributors to atmospheric pollution in most of the world's cities. Hence, the need to find effective methods of controlling automobile emissions becomes imperative. Available automobile emissions' control measures which include various legislations and responses to legislations such as improvement in the state of the art controls, greater attention towards automobiles growth, improvement of engine design features, periodic tune-up, the use of alternative fuels and the development of non-fossil energy sources were reviewed in this paper.

Increasing worldwide effort to decrease the amount of air pollutants (NOx, COx, SOx, volatile organic compounds etc.) according to strict environmental legislative opens a new worldwide business. Environmental catalysis has seen one of the biggest growth in importance. This report is focused to NOx emission control. Commercial techniques of NOx abatement and future NOx emission control possibilities are discussed. The main stress is given to the selective catalytic reduction of NO with hydrocarbons as one of the promising and attractive systems to NOx abatement from mobile and stationary sources of NOx operating in the excess of oxygen.
