El ACAAN y sus instituciones como catalizadores de la gobernanza ambiental en México: del TLCAN al T-MEC
Bibliographic record
Abstract
The renegotiation of the North American Free Trade Agreement (NAFTA) culminated in the signing of the new United States-Mexico-Canada Agreement (USMCA) and a series of symbolic changes on environmen-tal issues. Environmental protection was not a priority for any of the three member states during the round of negotiations. This has been analyzed and criticized by environmental groups, who argue that a twenty-first-century trade agreement should not ignore the environmental and climate crisis we are suffering today. This article summarizes the content of the North American Agreement on Environmen-tal Cooperation (NAAEC), still in effect, and analyzes the changes slated for environmental issues with the signing of USMCA and its new environmental accord, the Agreement on Environmental Cooperation (AEC). Both USMCA’s Chapter 24, dedicated to the environment, and the new AEC are steps backward that paralyze the advances for environmental regulation in the region.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
