The Current State of Pollution in Mexico City
Mexico City, one of the largest cities in the world, faces significant challenges with air pollution. Its location in a valley traps pollutants, contributing to a blanket of smog that often covers the cityscape. Despite efforts to combat pollution through initiatives like vehicle emissions testing and the ‘Hoy No Circula’ program—which restricts vehicle usage by plate number to reduce traffic—the air quality in Mexico City often falls short of international health standards.
Industrial activities and the vast number of vehicles on the road are primary contributors to the air pollution problem. The high concentration of nitrogen dioxide, sulfur dioxide, and particulate matter poses health risks ranging from respiratory problems to cardiovascular issues. The city’s dense population only amplifies the impact of these pollutants, with millions potentially exposed to harmful air substances, especially during periods of high pollution known locally as “contingencias ambientales”.
Another aspect of air pollution in Mexico City is the impact of seasonal variations. The dry season, which typically runs from November to May, often sees a spike in air pollution levels. During this period, the lack of rain means that pollutants do not get washed away, while thermal inversions are more common, trapping pollution closer to the ground where people live and breathe.
Moreover, the issue of pollution is not restricted to outdoor air. Indoor pollution, often attributed to the use of certain cleaning products, cooking with charcoal or wood, and the presence of mold, is another health concern. Public awareness campaigns and regulations have been aimed at improving household air quality, but the impact of these measures is still being evaluated. What remains clear is that both outdoor and indoor air quality in Mexico City require consistent monitoring and proactive strategies to safeguard the health of its residents and the environment.

The high levels of pollutants in the air not only obscure the panoramic views of the city but also pose a significant risk to public health.
One major contributor to air pollution in Mexico’s capital is vehicular emissions. With over five million vehicles on the road, the exhaust from cars, trucks, and buses accounts for a substantial share of the airborne contaminants. The city’s geographical location further exacerbates the problem. Nestled in a valley surrounded by mountains, Mexico City is prone to thermal inversions that trap pollutants close to the ground, preventing them from dispersing and diluting in the atmosphere.
Industrial activities are another source of pollutants in the air. Factories and power plants around the city release significant amounts of sulfur dioxide, nitrogen oxides, and particulate matter into the air. While regulations exist to control industrial emissions, enforcement can be inconsistent, and many facilities continue to contribute to the city’s air quality problems. The growth in industrial zones has also meant that many residents are now living closer to these sources of pollution.
Aside from vehicles and industry, everyday activities of Mexico City’s inhabitants also play a role in air pollution. The use of solid fuels for cooking and heating in some areas, the accumulation of waste, and even the dust from construction sites all add to the particulate matter suspended in the air. Efforts are being made to address these issues, but they persist as contributing factors to the city’s ongoing struggle with air quality.
