Nuevo León’s metropolitan emissions inventory is in its final adjustments, with the state saying the results should be presented to the public in the coming weeks. The inventory is being assembled with federal authorities and the UNAM, and the federal government is expected to make the public presentation.
The state’s Environment Secretary, Raúl Lozano Caballero, said the last meeting to close the study is expected before the end of August. The work is intended to show how fixed and mobile sources contribute to air pollution across the metropolitan area.
Why it matters
For companies operating around Monterrey, the useful part is the baseline: a clearer accounting of sources and their relative contribution can inform compliance planning, operational priorities and the public conversation around industrial activity.
The timing also matters. The inventory had previously been described as finished, but it was not released. This latest update moves the process from promised publication toward a defined final meeting and a public release window.
The other side
The sources do not provide a firm publication date or any new enforcement measures. The immediate development is informational: finishing the study, publishing the methodology and showing the share attributed to each source.
What to watch
Watch for the final meeting before August ends, the public release by the federal government and the breakdown of fixed versus mobile sources across the metropolitan area.
