Technological, Energy and Environmental Tendencies from the Use of Diesel Fuel -2007
The present study evaluated the environmental benefits from the introduction of ultra-low-sulfur diesel (ULSD) -Concentrations below 15 ppm- in the reduction of emissions into the atmosphere, as well as the environmental effects that scrapping policies will have as a result of opening up the border to vehicles imported from the United in compliance with the North American Free Trade Agreement (NAFTA). It was demonstrated that using this type of fuel will reduce, by 2025, 500,000 annual tons of nitrogen oxides (NOx) emissions, and 20,000 tons/year of particulate matter (PM10), which would have an important impact on the air quality of our country. Furthermore, the scrapping program showed positive short-term results, accelerating the renewal of the vehicle fleet and thereby inducing a reduction of pollutant emission levels.
ULSD is available on the northern border area of the country since 2007, extending its availability to the metropolitan areas of Guadalajara, Monterrey and Mexico City in 2008. However, to date, the benefits estimated in this study resulting from the introduction of ULSD has not been reached because of failure to comply with the last stage of the program established in NOM-086, which establishes the availability of ULSD fuel nationwide. Between October 2005 and May 2012 the heavy motor vehicle fleet increased by about 275,000 units, 10% of which represented used imported cars and 90% were new cars sold in the country.
