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

A federal court in New Mexico has granted a preliminary injunction against the state's PFAS labeling rule for consumer products, finding that the regulation likely violates constitutional protections for commercial speech. The court questioned whether the state's characterization of the label as a "consumer awareness" measure rather than a warning undermines the connection between New Mexico's stated health and environmental interests and the means used to achieve them.

Commission Proposes EU Public Procurement Act

The European Commission has proposed replacing the EU's three core procurement directives with a single, directly applicable Regulation that would fundamentally reshape how companies compete for public contracts across Member States.
