    Air pollution in Mega-Cities around the world is a big concern for their governments due to its negative effects on human health, animals, vegetation and building materials.

    Furthermore, these cities have limited resources to fight back pollution, that is why it is important to use methodologies like the cost-benefit analysis for helping decision makers to choose the best options for this task.

    This work reports on the cost-benefit analysis of replacing the additive commonly used in the gasoline sold in Mexico City before 1997, by the new additive called IMP-D-13, that is now currently used in this area.

    Two scenarios were analyzed, one considered the use of the new additive in a concentration of 400 ppm, and the other one considered 600 ppm.

    Both scenarios were compared with the scenario actually happening by the end of 1996 (base case).

    Experimental results of exhaust emission measurements from a fleet of 17 vehicles using both types of additives were used for calculating the costs and benefits of this action.

    The experiment was carried out for a travel distance of 20000 km (equivalent to 1 year).

    For the analysis the vehicular fleet profile was assumed to remain unchanged all along the travel distance.

    The benefits considered in this work were those stemming from human health improvement due to reduction in ozone.

    The costs were calculated as the incremental cost compared with the base case.

    The analysis found a benefit-cost ratio of at least 1 : 4.
