Executive Summary:
- The Ministry of Environment and Natural Resources (SEMARNAT) published an agreement that revokes the extension granted for the start of compliance with some points of NOM 044.
- To comply with NOM 044, it is essential that the country has ultra-low sulfur diesel (ULSD).
On April 25, 2024, SEMARNAT published in the Official Gazette of the Federation (DOF) the agreement by which the agreement that modified the validity of the period established in the notes of tables 1, 2 and 4, of numerals 4.1 and 4.2, exclusively with regard to the AA Standards, of the Mexican Official Standard NOM-044-SEMARNAT-2017 (Version 2017) is repealed. This standard establishes the maximum permissible emission limits of carbon monoxide, nitrogen oxides, non-methane hydrocarbons, non-methane hydrocarbons plus nitrogen oxides, particulate matter and ammonia from the exhaust of new engines that use diesel as fuel and that will be used for the propulsion of motor vehicles with a gross vehicle weight greater than 3,857 kilograms, as well as from the exhaust of new motor vehicles with a gross vehicle weight greater than 3,857 kilograms equipped with this type of engines. This agreement was originally published on November 26, 2021.
As its name indicates, the main objective of this Agreement is to invalidate several aspects of NOM 044 Version 2017 that regulate the moment of its entry into force.
What has been the history of NOM 044 2017?
- Previously, the automotive industry that imported or manufactured diesel-powered vehicles weighing more than 3.857 kg was governed by NOM-044-SEMARNAT-2006 (Version 2006), which had objectives and guidelines similar to those of Version 2017, but with considerably more lax pollution limits.
Since then, NOM-044 Version 2006 established that for the manufacture or importation of this type of motors it was necessary to obtain a “NOM Compliance Certificate” from the Federal Attorney for Environmental Protection (PROFEPA), a document that certified that the motor complied with NOM-044. The lack of this certificate implied significant fines and sanctions.
- Later, in 2018, NOM-044-SEMARNAT-2017 was published in the Official Journal of the Federation (DOF), with the aim of updating the standards applicable to new diesel engines to comply with the EPA 2010 regulation of the United States of America and the Euro VI regulation of the European Union. These regulations establish procedures to certify diesel engines that significantly reduce the emission of gases into the atmosphere.
In addition, NOM-044 Version 2017 establishes that PROFEPA must issue a “NOM Certificate”, which is the new name for the previous “NOM Compliance Reports”. The lack of this certificate could result in the imposition of various sanctions.
It is important to note that Version 2017 repealed Version 2006 of NOM-044.
- In addition, NOM-044 Version 2017 established three standards for diesel engines, namely: A, AA and B, with A being the most polluting and B being the least polluting.
Within the framework of energy transition policies, NOM-044 Version 2017 imposed a restriction on the production and importation of motors with A and AA standards until the end of 2020. However, according to the provisions of NOM-044 Version 2017, until that date, AA motors would be regulated by less strict regulations, until DUBA is fully available in the country.
- On November 11, 2020, SEMARNAT published in the DOF an agreement extending the entry into force of some provisions of NOM-044 Version 2017 referring to the AA standard, establishing the new compliance date for the end of 2021. It was highlighted that the applicable guidelines would continue to be more flexible for this type of engine.
This extension was again extended until the end of 2024 through another agreement published in the DOF by SEMARNAT on November 26, 2021. Therefore, the applicable guidelines, including the procedure for obtaining the NOM Certificate, would continue to be more lax.
- It is important to note that these extensions were necessary because, in order to comply with the NOM-044 Version 2017 standard, the country must have ultra-low sulfur diesel (ULSD). However, to date, ULSD is not fully available throughout the country.
- Despite the sensitivity of this situation, a non-governmental organization (NGO) filed a claim for protection against the SEMARNAT agreement that extends the entry into force of NOM-044 Version 2017 until the end of 2024. They argued violations of the right to a healthy environment and to health.
This appeal was resolved in favor of the NGO, and the corresponding ruling stated the following: i) SEMARNAT must revoke the extension of the deadline for the entry into force of NOM-044 Version 2017; ii) diesel engines that are imported or manufactured must comply with the guidelines established in Version 2017, having a period of 60 days for this purpose, during which SEMARNAT may not impose sanctions; and iii) once this period has concluded, the applicable regulations will be NOM-044 Version 2017.
What is the problem?
Companies dedicated to the manufacture or import of vehicles with this type of engine are the main ones affected by this decision. Although they have been complying with the NOM Certificate, as established by NOM-044 Version 2017, the reality is that said compliance has been carried out according to more lax standards.
It is important to note that in the amparo trial between the NGO and SEMARNAT, the companies holding NOM Certificates were not considered. These companies, which were not summoned, will be affected by the early entry into force of the 2017 Version.
The recent publication of SEMARNAT in the DOF, which nullifies the extension for the entry into force of the provisions of Version 2027, does not establish the 60-day period that the automotive sector should have to regularize itself, as indicated in the ruling of the amparo. It only left the agreement to extend the period “inoperative.”
Likewise, this new agreement does not establish what will happen to the NOM Certificates obtained under the extension agreement that is no longer in force.
Given the impossibility of ensuring the supply of DUBA, applying the standards of NOM-044 Version 2017 suddenly will mean that many companies will not be able to comply with it.
What are the next scenarios?
First of all, we must consider that it is the obligation of all parties involved to take care of the atmosphere and commit to the environment. The automotive sector has shown openness and willingness to comply with this standard, as long as there are sufficient inputs to make it possible, especially the DUBA.
Now, we must analyze the effects of this 'non-existence' decreed by SEMARNAT, given that it was extremely limited and the limits, scope and other legal implications were not clearly established. In particular, what will happen with the NOM Certificates in force to date?
Given this scenario, the automotive sector may attempt to file amparo lawsuits, basing its main arguments on: 1.- the brevity and limitations of the 'non-existence' agreement; and 2.- that they were not summoned to the trial brought by the NGO against SEMARNAT, despite having a legal interest in it.
