Improvement Assessment on the Quality of the Country’s Automotive Fuels -2005
This study analyzed the situation of fossil fuels in Mexico from a perspective concentrating on the environmental benefits which would result from the introduction of ultra-low-sulfur fuels (ULS) in the transport sector of the Mexico City Metropolitan Area (ZMVM), as well as in a nationwide scale. In accordance to the results obtained by the model developed, the introduction of ULS fuels would revert the upward trend of total vehicular pollutant emissions into the atmosphere, even if we take into account a significant increase in the vehicle fleet.
According to what is established in the program stipulated by NOM-086, in 2008 the introduction of ULS gas and diesel into the ZMVM was complied. It is expected that by 2020 the transport sector will reduce by 93% its dispersion of sulfur dioxide, 67% of nitrogen oxides, 56% of total hydrocarbons and 53% of particulate matter with regards to emissions that would exist if these fuel types where not introduced (baseline scenario). Nowadays, the national scenario is not very favorable, as Pemex has failed to comply with the last stage of the program established in NOM-086, which contemplates the availability of this fuel in the entire country. Had this goal been achieved, a reduction in emissions of the road transport sector for up to a 92% of sulfur dioxide, 67% nitrogen oxides, 57% in total hydrocarbons and 54% in particulate matter would have been reached. Only ULS Premium gasoline is available nationwide, while ULS Magna gasoline has been available since 2008 only in the Metropolitan areas in the Valley of Mexico, Guadalajara and Monterrey, and ULS diesel is available only on the northern border and in the Metropolitan areas in the Valley of Mexico, Guadalajara and Monterrey.
