Mexico's severe environmental pollution stems from a confluence of three structural factors:
With 120+ million people concentrated in valleys and basins (e.g., Valley of Mexico), intense urbanization creates massive localized emissions (vehicles, industry, waste) exceeding atmospheric dispersion capacity.
Economic disparity limits access to clean technology. Low-income households rely on older, high-emission vehicles, solid fuels for cooking/heating, and lack capital for efficiency upgrades (solar, EVs, insulation). Informal settlements often lack waste/sewage infrastructure.
While laws exist (LGEEPA), enforcement capacity is insufficient. Inspections are infrequent; penalties are often non-deterrent; industrial lobbying influences standards. Corruption allows non-compliance. Cross-border pollution (e.g., Tijuana River) adds complexity.
Air: CDMX frequently exceeds WHO PM2.5 limits. Water: Major rivers (Lerma, Santiago) heavily contaminated. Land: Municipal waste management crises. Public health burden (respiratory, diarrheal diseases) is substantial.
