On June 21, Mexico's Ministry of the Environment and Natural Resources published in the Official Gazette of the Federation the Mexican Official Standard "NOM-163-SEMARNAT-ENER-SCFI-2013, Carbon Dioxide emissions from light-weight vehicles' exhaust pipelines and their equivalence in terms of fuel economy, applicable to new automotive vehicles with a gross weight of up to 3,857 kilograms" (the "Standard"). The Standard is binding to trading companies of new lightweight vehicles (those with a gross weight not exceeding 3,857 kilograms) commercialized in Mexico (except when those companies commercialize up to 500 units per model/year). It aims to establish the parameters and methodologies for the calculation of both observed and desired corporate averages regarding CO2 emissions expressed in grams of CO2 per kilometer (g CO2/km), and their equivalence in terms of fuel economy expressed in kilometers per liter (km/l), based on new lightweight vehicles from model years 2014 through 2016 that use gasoline or diesel as fuel. In accordance with the above, the Standard establishes compliance values and parameters with target emissions for the period 2012 to 2016, which gradually reduce...
