Mexico's Air Pollution: Regulations And Their Impact

Mexico has implemented various regulations and initiatives to combat air pollution, a historically pervasive issue in the country, particularly in Mexico City, which was once labelled the world's most polluted city. Air quality legislation has been in place since the 1970s, with the Secretary of Health regulating seven criteria pollutants by setting maximum allowable concentrations. Mexico's Ecology and Climate Change Institute (INECC) also plays a crucial role in monitoring air quality and managing the Air Quality National Information System (SINAICA). Additionally, Mexico has introduced ProAire programs, which aim to reduce emissions, strengthen institutions, and protect public health through various measures such as promoting public transportation, regulating fuel consumption, and improving environmental education.

The Air Quality Mexican Official Standards set maximum allowable concentrations of pollutants

Mexico has been facing an air quality crisis for decades, with over 90% of the population breathing polluted air. The Air Quality Mexican Official Standards, or Normas Oficiales Mexicanas de Calidad del Aire (NOMs), were implemented in 1994 to regulate maximum concentrations of environmental contaminants. These standards are defined by the Secretary of Health and set maximum allowable concentrations for seven criteria air pollutants: carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate pollution (PM2.5 and PM10), and sulfur dioxide (SO2).

While the NOMs have been updated in recent years, some critics argue that the regulatory framework is lax and outdated, with the State failing to provide timely information on air quality. This is particularly concerning given that air pollution is the eighth-largest cause of death in the country, impacting those with heart disease, coronary artery disease, and congestive heart failure, as well as pregnant women, children, senior citizens, and those working outdoors.

To address this issue, Mexico's Ecology and Climate Change Institute (INECC), under the Secretary of Environment, monitors air quality and manages the Air Quality National Information System (SINAICA). The INECC aims to enforce the NOMs effectively and has taken steps such as requiring the reformulation of gasoline, closing or moving polluting factories, and implementing vehicular restrictions.

Additionally, Mexico has set a goal of achieving zero deforestation by 2030 and is working to modify mobility systems to prioritize public and active transport, such as electric transportation, cycling, and walking, over private vehicles, which are currently the main cause of air pollution in city centres. The country is also working to expand environmental health standards to align with the World Health Organization's health protection limits, ensuring that sectors like transportation and industry abide by these limits and reduce their emissions.

Mexico's Ecology and Climate Change Institute monitors air quality and manages the Air Quality National Information System

Mexico has been facing an air quality crisis for decades, with over 90% of the population breathing polluted air. The country's rapid industrial growth, population boom, and proliferation of vehicles have contributed significantly to this issue. Mexico's Ecology and Climate Change Institute (INECC) plays a crucial role in addressing this crisis by monitoring air quality and managing the Air Quality National Information System (SINAICA).

INECC, also known as the National Institute of Ecology and Climate Change, serves as the research arm of the Secretary of Environment, Secretaría del Medio Ambiente y Recursos Naturales (SEMARNAT). It is responsible for monitoring air quality across Mexico and enforcing regulations to ensure a healthy environment for its citizens. INECC's work is essential in combating the country's air pollution crisis and protecting public health, especially for those most vulnerable, such as individuals with heart disease, pregnant women, children, and senior citizens.

The institute regulates and sets maximum allowable concentrations for several criteria pollutants, including carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate pollution (PM2.5 and PM10), and sulfur dioxide (SO2). These regulations are vital in reducing emissions and improving air quality, ultimately mitigating the health risks associated with polluted air.

Additionally, INECC collaborates with various organizations to address climate change and environmental challenges. For example, the institute worked with the Global Environment Facility (GEF) and the United Nations Development Programme (UNDP) on the Sixth Communication, which included topics such as climate finance, scientific articles, and progress toward a low-carbon economy. This collaborative effort demonstrates INECC's commitment to tackling climate change and its recognition of the interconnectedness between air quality and climate change mitigation.

Mexico has also implemented initiatives to address the root causes of air pollution. The country aims to achieve zero deforestation by 2030 and is working to modify mobility systems to prioritize public and active transport, such as electric transportation, cycling, and walking. These measures aim to reduce emissions from transportation, which is currently the main cause of air pollution in Mexican cities.

ProAire's fourth iteration includes the renewal of bus fleets and expansion of the subway network

Mexico has been facing an air quality crisis for decades, with over 90% of the population breathing polluted air. The main sources of air pollution in Mexico are industrial growth, a sharp increase in population, and the proliferation of vehicles. To tackle this issue, ProAire, Mexico's air quality management programme, has implemented its fourth iteration, which includes the renewal of bus fleets and the expansion of the subway network.

The renewal of bus fleets aims to replace older, more polluting buses with newer, more environmentally friendly ones. This will help reduce emissions generated by transport, which is currently the main cause of air pollution in Mexican cities. The expansion of the subway network will provide a more efficient and sustainable transportation option for the population, reducing the number of vehicles on the roads and, consequently, the emissions that cause air pollution.

The fourth iteration of ProAire also includes other measures to improve air quality in Mexico. For example, the programme aims to give priority to electric public transport and active transport, such as cycling and walking. Additionally, the Mexican government is working to update and expand environmental health standards to align with the World Health Organization's health protection limits. This includes regulating sectors that are not currently adequately regulated, such as transportation and industry, and forcing them to reduce their emissions.

The Air Quality Mexican Official Standards, implemented in 1994 and regulated by the Secretary of Health, set maximum allowable concentrations of seven criteria pollutants: carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate pollution (PM2.5 and PM10), and sulfur dioxide (SO2). However, these standards have been criticised as lax and outdated, and the government has been accused of not fulfilling its duty to provide timely information on air quality.

The effects of air pollution on public health in Mexico are significant, and the government is under pressure to take urgent action. The fourth iteration of ProAire is a step towards improving air quality in the country and ensuring the population's right to a healthy environment and clean air.

The Mexican government is upgrading municipal wastewater treatment plants

Mexico has been facing an air quality crisis for decades, with over 90% of the population breathing polluted air. The main sources of air pollution in Mexico include industrial growth, a sharp increase in population, and the proliferation of vehicles. The Mexican government has implemented various regulations and initiatives to combat this issue. One such initiative is the upgrade of municipal wastewater treatment plants.

The landscape of wastewater treatment plants in Mexico has changed significantly over the last sixteen years, with a 200% increase in new plants and a 300% increase in abandoned plants. This discrepancy can be attributed to the federal government's focus on investing in new plants rather than maintaining existing ones, leaving the latter's fate in the hands of individual municipal governments. This has resulted in a lack of proper planning and financial self-sufficiency, leading to the abandonment of plants.

The Mexican government's approach to upgrading municipal wastewater treatment plants involves addressing the challenges of local water governance. This includes investing in new plants while also providing the necessary resources and support for their continued operation. This approach aims to ensure the optimal functioning of these plants, which is crucial for local governments to guarantee treated wastewater reaches the treatment plants.

Upgrading municipal wastewater treatment plants is a complex issue due to the high costs involved. It requires significant investment to renovate and upgrade these plants to improve their efficiency. However, the Mexican government's ideological dispute with political opponents over centralization versus decentralization of resources has impacted the effectiveness of their approach.

To address the issue, the Mexican government has proposed administrative solutions to end corruption by centralizing resources and delivering them directly to beneficiaries. Additionally, they have recognized the need for proper planning and financial self-sufficiency in municipalities to increase the effectiveness of wastewater treatment plants. This includes exploring low-cost, low-maintenance wastewater treatment systems and expanding environmental health standards to align with the World Health Organization's guidelines.
