Mexican emissions and efficiency standards draw upon both US and European standards as models. For example, current heavy-duty diesel vehicles can comply with either US 2004 or Euro IV equivalent standards, and light-duty emissions standards are a mix of US Tier 1 to 2 and Euro 3 and 4. Fuel quality standards require sulfur levels to be reduced in both diesel and gasoline, although implementation is not yet complete. Mexico has modeled its first light-duty vehicle efficiency standards after the US standards for model years 2012–2016.
