The emission control for commercial vehicles in Latin America has just begun and it brings an exceptional opportunity for the introduction of a common concept towards an air quality program suited for developing countries. The analysis of prior experiences accumulated by countries where legislations on that field have already been settled and improved is a worthy tool to choose the most convenient alternative to deal with the emission control in an affordable way. Steady-state test procedures provide enough information to estimate the engine emission levels on actual operation, avoiding the use of expensive facilities. Through simple and already well-proven methods and considering all aspects concerning the problem, from the fuel quality to the vehicle maintenance, it is possible to reach the main aim, the air preservation, alloting fewer resources and promoting Latin America's integration.
