Because of the large number of kilometers traveled each day by taxis, their emissions are quite high. Even though taxis account for only 3.4% of Mexico City’s vehicle fleet, the their emissions make 3.6% of particulate matter, 11.5% of sulfur dioxide, 10.7% of carbon monoxide, 10.2% of nitrogen oxide and 14% of volatile organic compounds of all transportation related emissions (McKinley et al., 2005). Thus, all the taxis around the city have to be diminished. Instead of taxis, the government should provide the residents with more buses and minibuses. The advantage of this policy is obvious: if there would be no taxis traveling in the city, less harmful gases would be emitted. Moreover, the analysis made by McKinley et al. (2005) suggests that a turnover of the taxi fleet due to its size and age would benefit from over $70 million US in reduced health impacts from air pollution, and would also benefit from fuel savings, whose costs summed up together, is greater than this measure’s investment cost. However, there are several drawbacks to this solution.

The second program, PROAIRE 1995-2000 (Programa para Mejorar la Calidad del Aire en el Valle de Me´xico – Program to Improve Air Quality in the Valley of Mexico) had other major accomplishments, such as the introduction of methyl tertiary butyl ether (MTBE) in gasoline to improve combustion efficiency, and carried out restrictions on the aromatic content of fuels and on the sulfur content in industrial fuel (McKinley et al., 2005). These programs have had significant impact on reduction of air pollution in the city. That is why more of these kinds of programs should be implemented in Mexico City, so the city can finally reduce the levels of air pollution to acceptable norms. For instance, the government should implement policies concerning taxis. According to Connolly (1999), taxis and individual cars that replaced traditional buses are the most polluting of all forms of transport. Approximately 110,000 taxis “circulate the streets of Mexico City” (McKinley et al., 2005, p.1955).
