Resolution 263/2026, issued by the Secretariat of Tourism and Environment and published in the Official Gazette on March 20, 2026, amends the specific procedure for obtaining the Environmental Configuration License (LCA). Following the amendment, applicants may obtain the LCA submitting certification test reports or without submitting them, but through the recognition of local or foreign environmental homologations.

The Resolution regulates the regime applicable to the issuance of the Local Environmental Homologation Validation Certificate (CVHAL) and the Foreign Environmental Homologation Validation Certificate (CVHAE), which allow proving compliance with the environmental requirements established in the applicable regulations, without the need to submit the corresponding testing reports, if the vehicle model holds a valid homologation.

Manufacturers and importers of light and heavy vehicles, trailers, semi-trailers, multi-stage vehicles, as well as engines who hold prior homologations based on certifications issued by agencies recognized by the United Nations (TRANS/WP29/343), as well as those issued by the United States Environmental Protection Agency or the National Highway Traffic Safety Administration, may validate such homologations without submitting test reports or certification protocols. This will be subject to compliance with the maximum limits established under the applicable environmental reference standards.

Regarding applicable technical parameters, the Resolution maintains EURO 5a as the environmental reference standard for light vehicles and EURO V for engines and heavy vehicles, pursuant to European Union regulations and equivalent standards of the United Nations Economic Commission for Europe (UNECE). It also admits equivalent technological standards from the United States and Brazil.

The Resolution also allows assigning LCAs, pursuant to article 1614 of the Argentine Civil and Commercial Code and expressly prohibits assigning them as collateral.

The Resolution establishes a specific regime applicable to private, non-commercial imports of motor vehicles. When the vehicle matches brand, model, version and technical characteristics, a previously issued LCA, environmental compliance may be accredited through the corresponding CVHAL or CVHAE. This regime is limited to one vehicle per importer per calendar year, and such vehicles may not be transferred for two years as of their customs clearance.

Finally, the Resolution provides that, where it is not possible to obtain a CVHAL or a CVHAE, vehicles imported by private individuals and suitable for road use that do not hold an LCA may be processed through a Vehicle Safety Certificate (CSV), issued by the Argentine Road Safety Agency (ANSV). In such cases, at the request of the ANSV or the Argentine Directorate of National Registries of Motor Vehicles and Pledges, the Undersecretariat of Environment in connection with the CSV may issue a Vehicle Environmental Labeling Technical Certificate (CTEAV).
